Answer:
No it will not make to the top of the hill
Explanation:
From the question we are told that
The velocity is 
The height of the hill is 
Generally from the law of energy conservation we have that
The kinetic energy of the pluck at the level position = The potential energy of the pluck at the maximum height the pluck can get to
So
=> 
=> 
=> 
Given that the maximum height which the pluck can get to at this speed given in the question is less than the height of the hill then conclusion will be that the pluck will not make it to the top of the hill
Yes, that’s very inspiring.
the reign of the sun is very an important because the typically is about the size of 6,000 ceilometers
Answer:
Explanation:
acceleration of a rolling body down an inclined surface is given by the formula
a = g sinθ / 1 + k² / R² , θ is inclination , k is radius of gyration , R is radius
It will not depend upon mass .
for solid sphere
k , radius of gyration = √(2/5)R
k² / R² = 2/5 = .4
a = g sin20 / (1 + .4 )
= 2.4 m /s²
from s = ut + 1/2 at²
100 = .5 x 2.4 t²
t = 9.13 s
For hollow sphere
k , radius of gyration = √(2/3)R
k² / R² = 2/3 = .67
a = g sin20 / (1 + .67 )
= 2 m /s².
from s = ut + 1/2 at²
100 = .5 x 2 t²
t = 10 s
So time taken are 9.13 and 10 s respectively.
When Particles are cold they move closer together and move slower. When they’re hot it’s the opposite.
