Answer:
The height of the Everest mountain is, x = 8514.087 m
Explanation:
Given data,
The gravitational field strength at the top of mount Everest, gₓ = 9.772 m/s²
The formula for gravitational field strength is,
<em> gₓ = GM/(R+x)²</em>
Where, x is the height from the surface of the Earth
Therefore,
(R+x)² = GM/gₓ
x = √(GM/gₓ) - R
Substituting the values,
x = √(6.67408 x 10⁻¹¹ X 5.972 x 10²⁴ / 9.772) - 6.378 x 10⁶
x = 8514.087 m
Therefore, the height of the Everest mountain is, x = 8514.087 m
Energy Produced by water and heatfrom the inner core of the earth of the earth
Answer:
mass of the composite lump is 10 kg
Explanation:
given data
mass = 4 kg
to find out
mass of composite lump
solution
we know energy is conserved so
so m1 = m2 = m0 that is 4kg
and
E(1) release+ E(2) release = E(1,2) rest
so γ(1)m(1)c² + γ(2)m(2)c² = Mc² ..........................1
that why here
|v(1)| = |v(2)| = 3/5 c ......................2
and
γ = 1 / √(1 − v²/c²) .......................3
put here v = 3 and c is 5
γ = 1 /√(1 − 9/25)
γ = 5/4
so
γ(1) = γ(2) = γ = 5/4
so from equation 1
γ(1)m(1)c² + γ(2)m(2)c² = Mc²
M = 2γm0
M = 2(5/4 )(4)
M = 10 kg
so mass of the composite lump is 10 kg
After the ball leaves the bat, the only forces on it are air resistance and gravity.
