Answer:
At the highest point and at the lowest point the velocity of the mass hung on a spring = 0
Explanation:
Simple Harmonic Motion ( S.H.M) : Simple harmonic motion can be defined as a type of motion were a body vibrates or moves to and fro along a straight line under the influence of a force, so that the acceleration of the body towards a fixed point (equilibrium position) is proportional to its distance or displacement from that point. Examples of bodies undergoing simple harmonic motion are
<em>⇒ The motion of a mass hung on a spring.</em>
<em>⇒ The motion of a simple pendulum</em>
<em>⇒ The motion of a loaded test - tube in a liquid.</em>
Motion of a mass hung on a spring:When a mass is hung to one end spring and other end is firmly clamped to a rigid support.(i)When the mass is in motion, (ii)it pulled down to its lowest point, passes through it equilibrium position (iii) goes to its highest point.
<em>(1) At the lowest and the highest point during the motion of a mass hung a spring, the velocity = 0</em>
<em>(2) At the equilibrium point or unstretched position the velocity is maximum</em>

The variable that is altered by the independent variable is called the dependent variable. the spectrum given out by the hypothetical unknown celestial object.

The term electromagnetic spectrum refers to the range of electromagnetic radiation's frequencies, as well as the wavelengths and photon energies connected to each frequency.
By analyzing the absorption spectra of the planets and moons, the electromagnetic spectrum experiment seeks to identify the components that make up their atmospheres.
From below one hertz to over 1025 hertz, electromagnetic waves are included in the electromagnetic spectrum.
The wavelengths that correlate to the frequency range from tens of thousands of kilometers to a small portion of the size of an atomic nucleus.
Starting at the low frequency (long wavelength) end of the spectrum, each frequency band's electromagnetic waves are referred to by a variety of names.
Hence the dependent variable is the one that changes as a result of the independent variable.

Answer:
1 m/s²
Explanation:
Force = mass × acceleration
F = ma ............ Equation 1
Where F = force, m = mass, a = acceleration.
Given: m = 0.058 kg, a = 10 m/s²
Substitute into equation 1
F = 0.058(10)
F = 0.58 N.
If the same force was used to hit the baseball,
F = m'a
a = F/m'.............. Equation 2
Where M' = mass of the baseball.
Given: F = 0.58 N, m' = 0.58 kg.
Substitute into equation 2
a = 0.58/0.58
a = 1 m/s²
I think it’s C. Marshmallow and toothpicks are used to show the composition of a water molecule
Here's the formula for the distance covered by an accelerating body in some amount of time ' T '. This formula is incredibly simple but incredibly useful. It pops up so often in Physics that you really should memorize it:
D = 1/2 a T²
Distance = (1/2)·(acceleration)·(time²)
This question gives us the acceleration and the distance, and we want to find the time.
(9,000 m) = (1/2) (20 m/s²) (time²)
(9,000 m) = (10 m/s²) (time²)
Divide each side by 10 m/s²:
(9,000 m) / (10 m/s²) = (time²)
900 s² = time²
Square root each side:
<em>T = 30 seconds</em>
