London lives 1200 meters south of Chick-fil-A and is thinking about going there for lunch. When she is ready to leave, she realizes she left her wallet at her Aunt's house. She walks 750 meters to her aunt's house and then 1000 meters to Chick-fil-A. It took her 30 minutes to get from her house to Chick-fil-A. What was her distance traveled?

Answers

Answer:

  1750 m

Explanation:

The distance traveled is the 750 meters to the Aunt's house plus the 1000 m from there to Chick-fil-A.

Electricity is the movement of electrons around a closed-loop known as a circuit.

Magnetism is a phenomenon that results from the motion of electric charges phenomenon resulting in the attractive and repulsive forces between objects.

Both electricity and magnetism are known to be similar in nature in that a magnetic field that is changing can create an electric field and also a changing electric field can create a magnetic field.

Find out which of the following sentences is a false statement. Group of answer choices The potential energy of a pair of positively charged bodies is positive. The potential energy of a pair of oppositely charged bodies is negative. The total work required to assemble a collection of discrete charges is the electrostatic potential energy of the system. The potential energy of a pair of negatively charged bodies is negative. The potential energy of a pair of oppositely charged bodies is positive.

Answers

The statements which are false from the choices above are:

The potential energy of a pair of negatively charged bodies is negative

The potential energy of a pair of oppositely charged bodies is positive

In scenarios of like charges, the potential energy is always positive, that is because we need to put energy in the system to bring like charges closer together.

Conversely, for unlike charges, the potential energy of the pair of unlike charges is negative, as a result of the energy expended by the system in pushing the charges away from each other.

Please complete the following:

You and Tim, who is larger than you, are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon when it had the greatest acceleration during start up? Why? Use Newton’s second law to explain.

Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton’s second law.

Answers

Answer:

First scenario,

From 2nd Newton's law

F = ma

from the above eqn, it's evident

a = F/m

that is to say, acceleration is inversely proportional to mass

The greater the mass, the smaller the acceleration and the higher the acceleration, the smaller the mass.

Thus, You was in the wagon when it had the greatest acceleration because You has the smaller mass and thus the acceleration will be greater.

Second scenario,

Since Sara pulls with greater force and Force is directly proportional to acceleration according to the second Newton's law,

F = ma

then, when You is in the wagon it had greater acceleration since they have the same mass.

Hi there!

We can use the conservation of energy:

Ei = Ef

The initial energy involves kinetic energy while the final energy involves maximum elastic potential energy, so:

1/2mv² = 1/2kx²

We can cancel out the 1/2s for ease of solving:

mv² = kx²

Plug in given values to solve for x:

√(mv²/k) = x

√(5.7)(12²)/(150)) = x

x = 2.339 m

What is Juan’s velocity between 0-5 seconds?

Answers

Juan’s velocity between 0-5 seconds would be 2 m/s, the slope of the position time graph represents the velocity of the object and between the 0-5 seconds slope of the line is 2.

What is Velocity?

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.

velocity= total displacement/Total time

As given in the problem we have to find the velocity of Juan between 0-5 seconds.

The displacement covered between 0-5 seconds is 10 meters.

the time taken to change position is 5 seconds,

the velocity of the Juan = 10/5

                                 =  2 meters/seconds

Thus, its velocity of Juan comes out to be 2 meters/second.

Following are the solution to the given points:

To find:

gravitational potential energy(GPE)=?

kinetic energy(KE)=?

concept=?

v=?

Solution:

For point a:

[tex]\to GPE= mgh[/tex]

             [tex]= 65 \times 10 \times 9.8\\\\ = 6370 \ J\\\\[/tex]

For point b:  

[tex]\to KE=\frac{1}{2} m v^2\\\\[/tex]

           [tex]=\frac{1}{2} \times 65 \times 14^2 \\\\=\frac{1}{2} \times 65 \times 14 \times 14 \\\\= 65 \times 14 \times 7 \\\\=6370\ J\\[/tex]

For point c:

As we've seen, there really is no force acting, and the mechanic KE: GPE is used. Because legitimate is conserved. Home energy loss means GPE must be equal to KE gain.

For point d:

A diver has risen 5 feet above the surface. As a result, according to the energy conservation law:

[tex]\to U_i + K_i= U_f + K_f\\\\ \to mg \times h + 0 = mg \times \frac{h}{2} + \frac{1}{2} m v^2\\\\ \to 9.8 \times 10 = 9.8 \times 5 + \frac{v^2}{2}\\\\\to 9.8 \times 10 - 9.8 \times 5 = \frac{v^2}{2}\\\\\to \frac{v^2}{2} =9.8( 10 - 5) \\\\\to v^2 =9.8( 10 - 5) \times 2 \\\\\to v^2 =9.8\times 5 \times 2 \\\\\to v^2 =98 \\\\\to v =98\ \frac{m}{s^2} \\\\[/tex]

Answers

Answer:

Explanation:

100 kph = 27.8 m/s

a = (v² - u²) / 2s

a = (22.2² - 27.8²) / (2(88))

a = -1.578282828...

a = -1.58 m/s²

t negative sign means the acceleration opposes the initial velocity.
