Help me pls!

Answers

Answer: Conductor, semiconductor, insulator

Explanation:

Just did the quiz

The correct option is option A.

The descending order in which electrons flow easily is:

Conductor, semiconductor, insulator

Conductivity and flow of electrons:

The correct order for materials by their ability to allow the flow of electrons, from most easily to least easily is Conductor, semiconductor, insulator.

Conductors are generally metals, they have plenty of free electrons due to which the electron flow is easy. Also, the conduction band and valance band in a conductor overlap, so they can conduct at room temperature.

In the case of semiconductors, the band gap between the conduction band and valance band is almost 1eV, so a little energy is enough to make the flow of electrons possible

Whereas, in insulators, the band gap is quite high and electrons can not jump from the conduction band to the valence band due to which the flow of electrons is not possible.

A river flows due east at 1.50 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 10.0 m/s due north relative to the water. If the river is 325 m wide, how far downstream is the boat when it reaches the north shore?

Answers

Answer:

Explanation:

Given that the velocity of the river is 1.50m/s due east.

The velocity of the boat with respect to the river is 10.0 m/s due north .

The width of the river is 325 m.

Note that the velocity of the boat will help in crossing the river.

Hence, speed = distance/time

Speed = 10.0 m/s

Distance = 325 m

Time = ?

10 = 325/time

Time = 325/10

Time = 32.5s

Hence in 32.5s the horizontal distance traveled by boat will be

= 1.50m/s × 32.5s

= 48.75m

How much Tension force is required to pull a 1500 kg car (it is being towed) forward with an acceleration of 3 m/s^2 if the friction force on the towed car's tires is pulling backward with a force of 2500 N?

Answers

If the pull is done horizontally, then the net force on the car is

F = T - f = (1500 kg) (3 m/s²)

where T is the magnitude of the tension in the towing cable, and f is the friction which points in the opposite direction. Then

T = f + (1500 kg) (3 m/s²)

T = 2500 N + 4500 N

T = 7000 N

As we know, the moon is a satellite of our earth, what is the

1024 kg (in hours, G = 6.67 x 10-9 N (m/kg) 3).

Answers

Answer:c

Explanation:c

This question involves the concepts of the time period, orbital radius, and gravitational constant.

The theoretical period of the moon is "658 hr".

The theoretical time period of the moon around the earth can be found using the following formula:

[tex]\frac{T^2}{R^3}=\frac{4\pi^2}{GM}[/tex]

where,

T = Time Period of Moon = ?

R = Orbital Radius = 3.84 x 10⁸ m

G = Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²

M = Mass of Earth = 5.97 x 10²⁴ kg

Therefore,

[tex]\frac{T^2}{(3.84\ x\ 10^8\ m)^3}=\frac{4\pi^2}{(6.67\ x\ 10^{-11}\ N.m^2/kg^2)(5.97\ x\ 10^{24}\ kg)}\\\\T^2=(9.91\ x\ 10^{-14}\ s^2/m^3)(56.62\ x\ 10^{24}\ m^3)\\\\T=\sqrt{561.34\ x\ 10^{10}\ s^2}[/tex]

T = 2.37 x 10⁶ s[tex](\frac{1\ h}{3600\ s})[/tex]

T = 658 hr

Students are asked to design an experiment about Newton’s 2nd Law. One student decides to roll a marble down a ramp into a pile of sand to measure the force impact.
Which variable should she manipulate to best exemplify the relationship explained by this law?

A.She should use a heavier marble, because the marbles will roll at the same rate of acceleration but more mass will produce a larger impact force.


B.She should increase the slope of the ramp by propping it up to higher height, because a steeper ramp will cause a greater rate of acceleration and a larger impact force.


C.She should use a heavier marble, because a bigger marble will accelerate more quickly down the ramp and cause a greater impact force.


D.She should decrease the slope of the ramp, because a ramp with a smaller slope will allow the ball more time to build up speed and cause a greater impact force.

Let's calculate the equivalent resistances on both circuits.

On Diagram A we have a series connection of the resistors. The equivalent resistance will be the sum of all resistances:

[tex]R_{eq}=1+1+1\\\\\boxed{R_{eq}=3\Omega}[/tex]

On diagram B we have a parallel connection of the resistors. The reciprocal of the equivalent resistance will be the sum of the reciprocals of all the resistances:

[tex]\frac{1}{R_{eq}} = \frac{1}{1} +\frac{1}{1} +\frac{1}{1} \\\frac{1}{R_{eq}}=3\\\\\boxed{R_{eq}=\frac{1}{3}}[/tex]

Therefore, the larger resistance occurs on diagram A.

For the current, recall

[tex]V=IR[/tex]

Where [tex]I[/tex] stands for current [tex]R[/tex] is the resistance and [tex]V[/tex] is the voltage. Rearranging the equation we have

[tex]I = \frac{V}{R}[/tex]

We can see that the larger the resistance, the smaller the current gets. So the larger current must happen in the diagram with smaller resistance. Therefore, the larger current occurs on diagram B.

1. A large ocean liner floating in the sea has a volume of
375 000 m² and displaces 50 000 m² of sea water. Determine the
density and mass of the ship. Explain why, despite being made
of metal, the ship is able to float.​

Answers

Answer:

Density of the ship :133.33 kg/m³

Mass of the ship :50,000,000 kg

Ships are able to float on water because they displace a volume that equals  their own weight

Explanation:

The formula for density is ;

Density = Mass/Volume

But the mass of  displaced fluid is give by the formula;

m=ρV where ρ is density of the fluid and V is volume of water displaced

Volume of liner= 375000 m³

Volume displaced = 50000 m³

The volume of the water displaced is equal to mass of the liner

I m³ = 1000 kg

50000 m³ = 50000*1000 =50,000,000 kg

50,000,000 kg ----------mass of the ship

So if ;

m= 50,000,000 kg

v= 375000 m³

ρ = m/V

ρ = 50,000,000/375000

ρ = 50,000,000/375000

ρ =133.33 kg/m³

Ships are able to float on water because they displace a volume that equals  their own weight. Additionally, the air contained in the spaces of the ship inside is much less dense than density of water aiding in the floating process.

A 55 kg boy running at 2.0 m/s jumps onto a 2.0 kg skateboard. Calculate the final velocity of the boy and the skateboard.​

Answers

Answer:

The final velocity of the boy and the skateboard is 1.93 m/s.    

Explanation:

We can find the final velocity of the boy and the skateboard by conservation of linear momentum:

[tex] P_{1} = P_{2} [/tex]

[tex] m_{b}v_{i_{b}} + m_{s}v_{i_{s}} = m_{b}v_{f_{b}} + m_{s}v_{f_{s}} [/tex]  (1)

Where:

[tex]m_{b}[/tex]: is the boy's mass = 55 kg

[tex]m_{s}[/tex]: is the skateboard's mass = 2.0 kg

[tex]v_{i_{b}}[/tex]: is the initial speed of the boy = 2.0 m/s

[tex]v_{i_{s}}[/tex]: is the initial speed of the skateboard = 0

[tex]v_{f_{b}}[/tex]: is the final speed of the boy =?

[tex]v_{f_{s}}[/tex]: is the final speed of the skateboard =?

Since the boy and the skateboard will have the same final velocity by entering the above values into equation (1) we have:

[tex] 55 kg*2.0 m/s + 0 = v_{f}(55 kg + 2.0 kg) [/tex]

[tex] v_{f} = 1.93 m/s [/tex]

Therefore, the final velocity of the boy and the skateboard is 1.93 m/s.    

I hope it helps you!                                

The final velocity of the boy and the skateboard is 1.93m/s

According to the law of conservation of momentum, the momentum of the bodies before the collision is equal to the momentum of the bodies after the collision.

Mathematically, [tex]m_1u_1+m_2u_2=(m_1+m_2)v[/tex]

[tex]m_1 \ and \ m_2[/tex] are the masses of the object

[tex]u_1 \ and \ u_2[/tex] are the velocities of the object

v is the final velocity

Given the following parameters

m₁ = 55kg

u₁ = 2.0m/s

m₂ = 2.0kg

u₂ = 0m/s

Required

Final velocity "v"

Substitute the given parameters into the formula to have:

[tex]55(2)+2(0)=(55+2)v\\110=57v\\v=\frac{110}{57}\\v= 1.93m/s[/tex]

Hence the final velocity of the boy and the skateboard is 1.93m/s

A box is being pulled across a horizontal surface by a 20 N force to the right.
a. If the box moves at a constant velocity, what do you know about the forces acting on the object?
b. If the box moves at a constant velocity, how much force opposes the motion of the box?
c. If the box experiences a force of 15 N to the left, along with the 20 N force acting to the right, what is the net force on the box?

Answers

A) If the box moves at a constant velocity, what we know about the forces acting on the object is; the sum of the forces acting on the object must be zero.

B) If the box moves at a constant velocity, the force that opposes the motion of the box is; Frictional Force of -20 N

C) If the box experiences a force of 15 N to the left, along with the 20 N force acting to the right, the net force on the box is; F_net = 5 N

We are told that a box is being pulled across a horizontal surface by a 20N force to the right.

A) Newton's first law of motion states that an object will remain at rest or continue in motion unless an external force acts on it. This means that any object/body moving with constant velocity will have no net external force acting on it. Thus, the sum of the forces acting on the object must be zero.

B) Since we are told that the box is moving at a constant velocity and that the sum of all forces must be zero. Then the force that will oppose the applied force of 20N to the right will be an equal but opposite force .

        In this case the opposing force will have to be the frictional force which will be -20 N to balance out the applied force.

C) We are told that a force of 15 N is acting to the left along with the 20 N force.

Thus, the net force will be;

F_net = 20 - 15

Trouble Times TwoThe sun was glowing dull red as it slipped down behind the curving horizon of Mars, but Gregory Hunter was not able to see it.There was no viewscreen in the ship's cabin; it was too tiny for that. Greg twisted around in the cockpit that had been built just big enough to hold him, and shifted his long legs against the brace-webbing, trying to get them comfortable.He knew he was afraid ... but nobody else knew that, not even the captain waiting at the control board on the satellite, and in spite of the fear Greg Hunter would not have traded places at this moment with anyone else in the universe.He had worked too hard and waited too long for this moment.He heard the count-down monitor clicking in his ears, and his hands clenched into fists. How far from Mars would he be 10 minutes from now? He didn't know. Farther than any man had ever traveled before in the space of 10 minutes, he knew, and faster. How far and how fast would depend on him alone."All set, Greg?" It was the captain's voice in the earphones."All set, Captain.""You understand the program?"Greg nodded. "24 hours out, 24 hours back, 90 degrees to the ecliptic1, and all the acceleration2 I can stand both ways."Greg grinned to himself. He thought of the months of conditioning he had gone through to prepare for this run ... the hours in the centrifuge to build up his tolerance to acceleration, the careful diet, the rigorous hours of physical conditioning. It was only one experiment, one tiny step in the work that could someday give men the stars, but to Gregory Hunter at this moment it was everything."Good luck, then." The captain cut off, and the blastoff buzzer sounded.He was off. His heart hammered in his throat, and his eyes ached fiercely, but he paid no attention. His finger crept to the air-speed indicator, then to the cut-off switch. When the pressure became too great, when he began to black out, he would press it.But not yet. It was speed they wanted; they had to know how much acceleration a man could take for how long and still survive, and now it was up to him to show them.Fleetingly, he thought of Tom ... poor old stick-in-the-mud Tom, working away in his grubby little Mars-bound laboratory, watching bacteria grow. Tom could never have qualified for a job like this. Tom couldn't even go into free-fall for 10 minutes without getting sick all over the place. Greg felt a surge of pity for his brother, and then a twinge of malicious anticipation. Wait until Tom heard the reports on this run! It was all right to spend your time poking around with bottles and test tubes if you couldn't do anything else, but it took something special to pilot an XP ship for Project Star-Jump. And after this run was over, even Tom would have to admit it....There was a lurch, and quite suddenly the enormous pressure was gone.Something was wrong. He hadn't pushed the cut-off button, yet the ship's engines were suddenly silent. He jabbed at the power switch. Nothing happened. Then the side-jets sputted, and he was slammed sideways into the cot.He snapped on the radio speaker. "Control ... can you hear me?
