Explanation:
The given data is as follows.
mass (m) = 0.160 kg, spring constant (k) = 8 n/m,
Maximum speed (
) = 0.350 m/s
Formula for angular frequency is as follows.
= 7.07 rad/sec
(a) Formula to calculate the amplitude is as follows.
A = 
= 
= 0.05 m
Hence, value of amplitude is 0.05 m.
(b) Displacement = 0.030 m
Formula for mechanical energy is as follows.
M.E = 
Putting the values into the above formula as follows.
M.E =
= 
= 
Joule
For x = 0.03,
As, P.E = 
= 
= 
Hence, calculate the kinetic energy as follows.
K.E = M.E - P.E
= ( - ) J
= 
J
Thus, we can conclude that kinetic energy of the puck when the displacement of the glider is 0.0300 m is J.

Answer:
it will decrease
Explanation:
According to the law of universal gravitation, the gravitational force exerted by the moon on the spacecraft is equal to the product of their masses and inversely proportional to the square of the distance that separates them. Therefore, as the spacecraft moves away, its distance increases and the force of attraction exerted by the moon decreases.
The volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.
<h3>Why does water change in volume?</h3>
Water is a substance that is known for its unique characteristics that makes it stand out among all other liquids.
One notable feature of water is it's ability to become denser when subjected to cooler temperatures i.e. water is more dense when cold.
As water cools or becomes less warm, it contracts and decreases in volume. When water decreases in volume, it becomes more dense.
Therefore, according to this question, it can be said that the volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.
