Answer:
PE = M g H gravitational potential energy
KE - 1/2 M V^2 kinetic energy
PE = KE kinetic energy equal to initial gravitational energy
Answer:4.04 m
Explanation:
mass of athlete
initial speed
To get the maximum height h of Athlete we conserve energy i.e.
Kinetic Energy of Athlete=Potential energy gained by athlete
(b)Speed at half of maximum height
Considering v be the velocity at half of maximum height
conserving Energy we can write
(as )
thus
So Athlete interact with the gravitational Field of Earth
I thank mars could be the closest to earths seasonal variations
The answer is DC power had to be converted in AC.
DC power is not usually in home. DC current must be converted to to AC, which is the standard in homes and to avoid short circuits.
DC or direct current explains the basic idea of electricity as a flow of electrons.
AC, also known as alternating current, electricity switches direction around 50-60 times each second. In here, electrons do not necessarily have to run in circles to transport energy, they simply run on the spot.
Answer:
Vy = 4.43 m/s
Explanation:
given data
velocity = 9 m/sec
angle horizontal = 29.5 degrees
solution
we get here ball initial vertical velocity will be here
Vy = v sinθ ...........................1
put here value and we get
Vy = 9 × sin(29.5 )
Vy = 4.43 m/s
