Answer 1

Answer:

Explanation:

No, not any of these substance will float in Methanol , simply because Methanol has a density of 0.79 g, if you put any substance that weighs more than 0.79 g, it will sink, it all depends on the weight if it is more or less than methanol  

2: D=m/v

D=135/50 = 2.7 g/cm³ ( Aluminum)

D=M/V

if two objects has the same mass but one has larger volume, then te one with larger volume has less density

example : 2 objects

mass of both=350

volume of the first one=500 and  the other 750

D1=M1/V1 = 350/500 =0.7

D2 = M2/V2 = 350/750 = 0.4666

D1 is larger than D2( with larger volume )

Texting and driving is a dangerous act
and is illegal in many areas. Suppose a driver takes 3.5 seconds to send a text. Travelling at 95 km/h, how far in meters did the vehicle travel while the driver was distracted? (Hint: How many seconds are in an hour?
How many meters are in a km?)

Answers

Answer:

s = 92.36 m

Explanation:

The distance covered by an object moving with uniform speed is given by the following formula:

s = vt

where,

s = distance covered by car during the time when driver was distracted in texting = ?

v = uniform speed of car = (95 km/h)(1 h/3600 s)(1000 m/1 km) = 26.39 m/s

t = time taken by the driver for texting = 3.5 s

Therefore, using these values in equation, we get:

s = (26.39 m/s)(3.5 s)

s = 92.36 m

300j/ 150 s² = M

A person is walking from the front of a train toward the back of a train at a constant velocity of 3 mph. The train is moving forward at a velocity of 20 mph. What is the velocity of the walking person relative to the land outside the train?

Answers

Explanation:

This is the Galilean transformation.

V' = V - U   where want to find V' in the primed frame of reference.

The primed frame is moving at speed U = -20 relative to the train.

V = -3 is the speed of the person in the frame of the train.

Then V' = -3 - (-20) = 17 mph relative to the land outside the train.

A hotwheels car is rolled from 0.72 meters to the 1.51 meter mark. What is the displacement of the toy car?
(do not enter units into your answer in canvas)

Answers

Answer:

it is d]

Explanation:

The displacement of the toy car will be 0.79 meters.

What is displacement?

The shortest route between two points is displacement.

It is a vector quantity to be displaced. This suggests that it has a size and a direction, and that it may be thought of as an arrow pointing from one place to another.

Distance is never less than displacement; it must always be more than or equal to it.

Displacement can be zero if the starting and end point are the same.

According to the question, the Hot wheel car rolled from 0.72 meters to the 1.51-meter mark.

So, the displacement of the toy car will be :

⇒1.51-0.72

=0.79

Hence, the total displacement will be  0.79 meters.

What are significant figures?

In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.

If a number describing the result of a measurement (such as length, pressure, volume, or mass) includes more digits than the number of digits permitted by the measurement resolution, only the digits allowed by the measurement resolution can be significant figures.

As given in the problem we have to convert 3 x 10⁻⁹ s into milliseconds

1 second = 1×10³ milliseconds

3 x 10⁻⁹ seconds =  (3 x 10⁻⁹)  ×  (1×10³ )

                            = 3 x 10⁻⁶milliseconds

Thus, 3 x 10⁻⁹ s converted into milliseconds it would be 3 x 10⁻⁶ milliseconds

During a sunny afternoon, the sun suddenly seems much less bright than usual. The daylight seems much less intense, as if there is a dense cloud cover, but there’s no clouds in the sky. After about half an hour, everything seems normal again. Which claim about the temporary decrease in light can be supported by the evidence?

Answers

Answer:

D). A sudden change in temperature increased the density of the atmosphere.

Explanation:

The claim that can be made and supported with evidence regarding the temporary decrease in light would be 'a sudden change in temperature will increase the density of the atmosphere.' As the temperature increases, the molecules in the atmosphere begin to move fastly which causes a decrease in atmosphere density while it increases with the fall in temperature. As a result, the intensity of sunlight gets affected due to molecules being heavier and floating in the atmosphere. Thus, option D is the correct answer.

Answer:  Its the atmosphere

A car accelerates from rest at 7.55 m/s2 for 4.25 s.
Determine the final velocity of the car.
And calculate the cars displacement.

Answers

Explanation:

This problem is on the motion of a car.

given data.

acceleration a=7.55m/s

time t= 4.25 sec

1. Determine the final velocity of the car.

we know that

acceleration= velocity/time

substituting our given data we have

7.55= v/4.25

v=7.55*4.25

v=32.08m/s

2.  calculate the cars displacement.

we also know that

velocity= distance/time

distance= velocity*time

distance= 32.04*4.25

distance= 136.37m

If the acceleration of a motorboat is 4.0 m/s2, and the motorboat starts from rest, what is its velocity after 6.0 s?

Answers

Answer:

The velocity of the motorboat after 6s is 24 m/s.

Explanation:

Given;

acceleration of the motorboat, a = 4.0 m/s²

initial velocity of the motorboat, u = 0

time of motion of the motorboat = 6s

Apply the following kinematic equation to determine the velocity of the motorboat after 6 ;

v = u + at

v = 0 + (4 x 6)

v = 24 m/s

Therefore, the velocity of the motorboat after 6s is 24 m/s.

A satellite in space has a mass of 252 kg. The engines on it provide a net force of 6.81×10-3 N. How long will it take for this satellite to go from rest to a final velocity of 262 m/s forward?

Answers

Acceleration = (force) / (mass)

Acceleration = (6.81 x 10⁻³ N) / (252 kg)

Acceleration = 2.70 x 10⁻⁵ m/s²

Time = (change in v) / (acceleration)

Time = (262 m/s) / (2.70 x 10⁻⁵ m/s²)

Time = 9,703,704 seconds

Answers

Answer:2.5s

Explanation:

Idk I guessed and got it right

Friction is the force that exists between two surfaces that are sliding or attempting to slide across each other.

The acceleration produced by the friction of water is a = [tex]-10 m/s^2[/tex]

The boat takes 2.5 seconds to slow down.

What causes of friction?Surface roughness: When two rough surfaces collide, they generate frictional force or an opposing force, which can sometimes be converted into heat. Body deformation: Deformations in the body or the surface of the body in contact may cause friction during motion.Friction is the force that exists between two surfaces that are sliding or attempting to slide across each other. For example, friction makes it difficult to push a book across the floor. Friction always acts in the opposite direction that the object is moving or attempting to move.

 The equation that rules the change of velocities is:

[tex]V = V _0 + at[/tex]

Where:

a   = acceleration

Vo = initial speed

v = final speed

t    = time

The acceleration produced by the friction of water is a = [tex]-10 m/s^2[/tex] and the boat is initially traveling at v=30 m/s. When the motor is shut off, the boat will start braking until it stops. We need to find the time it takes to ready the final speed of v=5 m/s.

t = [tex]\frac{V - V_0 }{a}[/tex] = -5-30 /10 = 2.5 s.

The boat takes 2.5 seconds to slow down.

Eric has a mass of 19.0 kg on the earth. What is Eric's weight on earth? What is Eric's weight on Mars? where the acceleration of gravity is approximately 0.381 of that of Earth's? ________.

Answers

Answer:

Weight on Earth = We = 186.2 N

Weight on Mars = Wm = 70.94 N

Explanation:

The weight of an object is defined as the force applied on the object by the gravitational field. The magnitude of weight is given by the following formula:

W = mg

were,

W= Weight of Eric

m = mass of Eric

g = acceleration due to gravity

ON EARTH:

W = We = Eric's Weight on Earth = ?

m = Eric's Mass on Earth = 19 kg

ge = acceleration due to gravity on Earth = 9.8 m/s²

Therefore,

We = (19 kg)(9.8 m/s²)

We = 186.2 N

ON MARS:

W = Wm = Eric's Weight on Mars = ?

m = Eric's Mass on Mars = 19 kg

gm = acceleration due to gravity on Mars = 0.381(ge) = (0.381)9.8 m/s² = 3.733 m/s²

Therefore,

Wm = (19 kg)(3.733 m/s²)

Wm = 70.94 N
