Answer:
K.E=365.2 J
Explanation:
Given data
Weight w =953 N
radius r=1.68 m
F=73.9 N
t=2.55 s
g=9.8 m/s²
To find
Kinetic Energy K.E
Solution
From the moment of inertia

The angular acceleration is given as

The angular velocity is given as

So the Kinetic Energy is given as
Answer:
is this it?
Explanation:
λ = h/mv, where λ is wavelength, h is Planck's constant, m is the mass of a particle, moving at a velocity v. de Broglie suggested that particles can exhibit properties of waves.
If we compare the energy of visible light to the energy of X-rays, we find that X-rays have a much higher frequency. Usually, electromagnetic radiation with higher frequency (energy) have a higher degree of penetration than those with low frequency.
This shows the sunlight shining on the moon is creating a shadow. The part of the shadow that we don’t see from Earth is called the eclipse. Since the Earth gets a shadow from the moon, that causes the rest of the Earth to light up which causes a lunar eclipse.
Explanation:
Speed is distance divided by time (s = d/t)
