If the maximum linear velocity her center of mass reaches is 2.3 m/s, what is her maximum angular velocity

Answers

Answer 1

Like linear velocity, angular velocity is the relationship between the variation of angular space at a given time.

It was agreed that the trajectory of the movement is clockwise. Thus, the movement that follows this orientation will be positive and the opposite, negative.

For the formula relating the linear velocity, it is necessary to take into consideration the following formula

[tex]v = \omega \times R[/tex]

For example, for a R = 0.738 m

[tex]2.3 m/s = \omega \times R \therefore\\ R = 0.738m \therefore\\\omega = 3.12 \frac{rad}{s}[/tex]

What are ionic bonds?

The electrical attraction between two ions with opposing charges creates an ionic bond, also known as an electrovalent bond, in a chemical molecule.

Ionic compounds are created by ionic bonds, while covalent bonds create covalent compounds. Ionic bonds are created by a complete transfer of electrons, whereas covalent bonds are created by sharing electrons.

Covalent bonds are weaker than ionic ones. Ionic compounds have higher melting and boiling points.

Therefore, the correct option is D.

Two wires A and B made of the same material and having the same lengths are connected across the same voltage source. If the power supplied to wire A is six times the power supplied to wire B, what is the ratio of their diameters

Answers

Answer:

sqrt (3) : sqrt (2)

Explanation:

Given that Two wires A and B made of the same material and having the same lengths are connected across the same voltage source.

Since they are both made of the same material, they will have the same resistivity.

Resistance is directly proportional to the length of the wire and inversely proportional to the cross sectional area.

Resistance R =1/ πr^2

If the power supplied to wire A is six times the power supplied to wire B, that is,

Pa = 6Pb

Where

Power P = IV

Since the same voltage passes through both wires,

P = V^2/R

Substitutes resistance R into the equation .Therefore,

V^2 ÷ 1 / πr^2 = 6( V^2 ÷ 1 / πr^2 )

V will cancel out , leaving

πr^2 = 6πr^2

Pi( π) will also cancel out. And since diameter d = 2r

r = d/2

Substitutes r into the equation

(d/2)^2 = 6( d/2)^2

d^2/4 = 6( d^2/4)

d^2/4 = 3d^2/2

da^2/2 = 3db^2

(Da/Db)^2 = 3/2

Da : Db = sqrt (3) : sqrt (2)

therefore, the ratio of their diameters is

sqrt (3) : sqrt (2)

The ratio of the diameter of Wire A to Wire B is; √6 : 1

What is the power in the wire?

Since both wires are made of the same material, they will definitely have the same resistivity.

Formula for the resistance with area is;

R = 1/A = 1/(πr²)

We are told that the power supplied to wire A is six times the power supplied to wire B. Thus;,

Pa = 6Pb

Since the same voltage passes through both wires, then formula for power in both cases is; P = V²/R. Thus;

V² ÷ (1/πr_a²) = 6(V² ÷ (1/πr_b²))

V and π will cancel out to give;

r_a² = 6r_b²

We know that radius; r = d/2

Thus;

(d_a/2)²= 6(d_b/2)²

d_a²/4 = 6(d_b²/4)

(d_a/d_b)² = 6

d_a/d_b = √6 : 1

A trebuchet launches a pumpkin at an angle of 27 degrees at an initial velocity of 32 m/ s from the ground. What is the apogee of the pumpkin?​

Answers

Answer:

10.77 m

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 32 m/s

Angle of projection (θ) = 27°

Acceleration due to gravity (g) = 9.8 m/s²

Apogee i.e maximum height (H) =?

Thus, the apogee i.e the maximum height of the pumpkin can be obtained as follow:

H = u² Sine² θ /2g

H = 32² × (Sine 27)² / 2 × 9.8

H = 1024 × (0.454)² / 19.6

H = (1024 × 0.206116) / 19.6

H = 10.77 m

Thus, the apogee i.e the maximum height of the pumpkin is 10.77 m.

How would natural cycles (day/night, moon phases) change if gravity did not
exist?

Answers

Answer: Eh, we would be dead...

Explanation: First off, the moon is orbiting us for one reason, gravity. and if the switch for gravity just flicked off, poof! The moon would be speeding away at 1,000-2,000 hours! And the reason that we orbit the sun is gravity too. So every planet would fling into space. Everything in the UNIVERSE would fling into space. That much flying debris would eventually smash into earth. Well, if we did survive that, then we would freeze instantly because when we travel too far away from the star that we orbit, the planet would become very life-threateningly cold. And in this case, we are traveling away from the sun, which is the star we orbit. If we still manage to survive THAT, then we...would actually die from the start, cuz what holds our planet together?

A fundraising company agrees to donate an extra $75 for every $100 the school raises through selling cookies. Part A: What is the constant of proportionality

Answers

Answer:

3/4 0r 0.75

Explanation:

Let E represent the extra cash.

Let R represent the amount raised.

From the question given above, we can say that:

The extra cash (E) is directly proportional to the amount raised (R) i.e

Extra cash (E) ∝ Amount raised (R)

E ∝ R

E = KR

NOTE: K is the constant of proportionality.

With the above formula, we can obtain the value of K as follow:

Extra cash (E) = $ 75

Amount raised (R) = $ 100

Constant of proportionality (K) =?

E = KR

75 = K × 100

Divide both side by 100

K = 75/100

K = 3/4 0r 0.75

Thus, the constant of proportionality is 3/4 0r 0.75

The force was increased
The force was decreased
The mass was increased

Answers

2 Answers: Choice A, Choice BMass was decreasedForce was increased

=========================================

Explanation:

If the force is kept the same, but the mass was decreased, then the car will travel further. The less mass an object has, the less inertia it has. Inertia is the tendency for the object to stay at rest if it's initially at rest (or the tendency for the object to stay in motion if already in motion).

If the mass is kept the same, but the force was increased, then the object will travel further than before. The same idea applies as discussed in the last paragraph.

------

If the force was decreased and mass kept the same, then there is less push, which results in the object traveling a shorter distance. If the mass is increased but the force kept the same, then the object moves a shorter distance because there's more inertia to overcome. There are more particles needed to be moved and they resist motion if at rest.

Andrew and Deshawn are teammates on a high school soccer team. They’ve been playing soccer together for years. They both play the center forward position. Some years, Andrew is better than Deshawn and serves as the team’s starter. Other years, Deshawn is the stronger player and gets the most playing time. They are both very competitive with each other. Although they know each other well, they have never been friends.

In practice yesterday, the team was running drills in the rain. Deshawn slipped in the mud and collided with Andrew. Andrew hurt his knee badly in the fall and will have to sit out for several weeks.

The next day, Andrew told everyone at school that Deshawn hurt him on purpose to get more playing time. Deshawn retaliated by sharing private information about Andrew on social media. Andrew’s best friend Mateo saw the collision. He knows it was a complete accident.

Pick the role of Andrew, Deshawn, or Mateo.
What are the main issues/problems from this person’s perspective?
What ethical issues are involved for this person?
Why are these ethical issues relevant for this person?
How should the person you chose handle the situation?

Answers

Answer:

1. I pick the role of Mateo.

2. The main problems from Mateo's perspective are: He knows that the collision was a complete accident and that Deshawn did not injure Andrew on purpose. Because Andrew told everyone that Deshawn injured him on purpose, Deshawn did something unethical by sharing private information about Andrew on social media.

3. The ethical issues are: Andrew took his hurt and frustration of being injured and missing play time out on Deshawn, so he slandered him by saying that Deshawn hurt him on purpose. Deshawn then retaliated by sharing personal information about Andrew on social media, which is also unethical.

4. These issues are relevant to Mateo because he is Andrew's best friend AND he saw the incident happen and knows it was an accident.

5. If I was Mateo, I would talk to Andrew and explain to him that I know he is mad that he is injured and can't play for several weeks, but telling everyone that Deshawn did it on purpose wasn't right or good sportsmanship. I would encourage Andrew to meet with Deshawn with me and have Andrew apologize to Deshawn for saying it was his fault, and then encourage Andrew to go and tell everyone the real story. I would also encourage Deshawn to apologize for posting private information about Andrew, have Andrew ask him to take it down, and then ask Deshawn to post another post saying why he did it and that he was sorry. I would also encourage them to work together, since they are both star players.

A force of 1000N is applied to push
a mass of 500kg. How quickly does
it accelerate?

Answers

Answer:

Explanation: use f= ma

we get 1000 ÷ 500 = a

∴ a = 2 m/s²

When a mass of 500 Kg with the force 1000N, the acceleration produced is equal to 2m/s².

What is Newton's second law of motion?

According to Newton’s second law of motion, the force equals the mass of the object times acceleration when the object has constant mass.

This law states that acceleration depends on two variables. The first variable is the mass and the net force acting on the body. The acceleration is directly proportional to the net force acting and inversely proportional to the mass.

Newton’s second law can be represented in the equation as follows:

[tex]F= ma[/tex]

or, [tex]a =\frac{F}{m}[/tex]

Acceleration or gaining speed happens when a force acts on an object.

Given the mass of the object, m= 500 Kg

The force applied on the object, F = 1000N

The acceleration produced in the mass, a = F/m = 1000/500 = 2m/s².

Therefore, the mass accelerates at a rate of 2m/s².

The vehicle land-speed record has long been held by rocket cars. These vehicles resemble the high-speed rocket planes that were used in the early days of the space program, but they have heavy metal wheels. On September 5, 1997, the world land-speed record was set by the British-built Thrust SSC rocket car, which had a top recorded speed of 341 m/s. The kinetic energy of the car at this speed is 5.289 × 108 J. What is the car’s mass?

Answers

Answer:

9096.93 Kg

Explanation:

The following data were obtained from the question:

Velocity (v) = 341 m/s

Kinetic energy (KE) = 5.289×10⁸J.

Mass (m) =.?

The mass of the car can be obtained as follow:

KE = ½mv²

5.289×10⁸ = ½ × m × 341²

5.289×10⁸ = ½ × m × 116281

5.289×10⁸ = m × 58140.5

Divide both side by 58140.5

m = 5.289×10⁸ / 58140.5

m = 9096.93 Kg

Therefore, the mass of the car is 9096.93 Kg
