Answer:
Part a)

Part b)
It will not able to cross the pole
Explanation:
As we know that ball is hit with speed of 110 ft/s at an angle of 35 degree
so here we will say


now at the maximum height the vertical velocity will become zero
so here we can use kinematics

here we have



now we have


Part b)
now the height of ball is related to the distance from point of projection is given as

now we know that



since its coming negative so it will not able to cross the pole
Sm = small piston
la = large piston
P=F/A
P=15000/(20^2)π
F of sm = PA
= (75/2π)•((8^2)π)
= (75•64)/2
= 4800/2
= 2400N
We already know the pressure but giving it in an approximate decimal form, to two significant figures (since that's what your supplied precision is at):
a) 12 Pa
b) 2400 N
The heat of fusion must be approx from 0 to infinity
The cloud chamber, the Geiger counter, and a piece of
photographic film can all reveal the presence of radioactivity.
Batteries don't.
