Answer:
Explanation:
First of all, we need to find the pressure exerted on the sphere, which is given by:
where
is the atmospheric pressure
is the water density
is the gravitational acceleration
is the depth
Substituting,
The radius of the sphere is r = d/2= 1.1 m/2= 0.55 m
So the total area of the sphere is
And so, the inward force exerted on it is
1. True
2. False
3. True
4. True
5. Not sure
6. False
7. True
Hope this helps!!
answer:
MAXIMUM SPEED
explanation:
IM SURE THAT IS THE ANSWER
Explanation:
X-rays are almost same as the visible light as they both electromagnetic waves with same speed. However, the only difference the energy level of photons of X- rays are higher than those of the visible light. This is because the frequency of the X-rays are higher.
E=
h= plank's constant and \nu is the frequency of the wave. So, higher the frequency higher will be the energy of the wave.
