Answer:

Explanation:

Given

radius of purse from center r_p=2\ m

radius of wallet from center r_w=2.3\ m

Merry - go - round is undergoing uniform circular motion therefore angular velocity is constant

acceleration of purse is equal to centripetal acceleration a_p=\omega ^2\times r

where \omega =angular\ velocity

2=\omega ^2\times 2

\omega =1\ rad/s

acceleration of wallet is

a_w=\omega ^2\times r_w

a_w=1\times 2.3=2.3\ m/s^2

A block lies on a horizontal frictionless surface and
zhenek [66]

Answer:

0.1 m

Explanation:

F = Force exerted on spring = 3 N

k = Spring constant = 60 N/m

x = Displacement of the block

As the energy of the system is conserved we have

Fx=\dfrac{1}{2}kx^2

\\\Rightarrow x=\dfrac{2F}{k}

\\\Rightarrow x=\dfrac{2\times 3}{60}

\\\Rightarrow x=0.1\ m

The position of the block is 0.1 from the initial position.

Newton's _____law states that when one object exerts a force on a second object, the second object always exerts a force back on
Nina [5.8K]
<h2>Answer:Third</h2>

Explanation:

Newton's third law states that every action force has a equal and opposite reaction force.

Example 1:

Consider yourself hitting a wall with your hand,you are exerting a force on the wall but still you feel hurt because the wall exerts same force on your hand in opposite reaction.

Example 2:

Consider yourself standing on ground.You are exerting force on ground.But how are you able to stand on ground even if your mass is forcing you to go down?The answer is normal reaction force.The ground exerts a force on your feet which makes you to stand still.

The atomic number of magnesium is 12. This means that its nucleus must contain
lana [24]
<span>The correct answer is D) 12 protons and no electrons. This is correct because the number of protons in the nucleus of the atom is 12. The number of protons in the nucleus represents the atomic number. Therefore if there are 12 protons in the nucleus, the atomic number is 12.</span>
