Yes, if the temperature increases, than that means the particles are moving faster. Temperature is the measure of movement of particles in an object or substance.
By thermal energy, you mean adding heat correct....? I'm not very good at this sort of thing, but I gave you what I have..

Answer:
v₂ = 48 mph
Explanation:
We know that,
Speed = distance/time
A German Shepherd takes 4 hours to cover a distance, if it travels at a speed of 36mph.
We need to find the speed to cover the same distance in 3 hours.
So, the new speed is 48 mph.
simple harmonic motion is a special type of periodic motion or oscillation where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.
Answer:
y = L h / a √√ (2q V m)
Explanation:
This is a diffraction exercise, so we must use the D'Broglie relation to encode the wavelength of the electron beam.
p = h / λ
λ= h / p
the moment is
p = m v
λ = h / mv
Let's use energy conservation
E = K
q ΔV = ½ m v²
v = √ 2qΔv / m
λ = h / (m √2q ΔV / m)
λ = h / √ (2q ΔV m)
Having the wavelength of the electrons we can use the diffraction ratio
a sin θ = m λ
First minimum occurs for m = 1
sin θ = λ / a
let's use trigonometry for the angles
tan θ = y / x
as in these experiments the angles are very small
tan θ = sin θ / cos θ = sin θ
sin θ = y / x
we substitute
y / x = λ / a
y = x λ / a
we replace the terms
y = L h / a √√ (2q V m)
