Answer:
Explanation:
Given
mass of satellite
orbital radius
mass of Earth
Minimum amount of Energy to move Satellite from its orbit to an infinite distance is sum of Potential Energy + Kinetic Energy of Satellite
Where
i.e. Energy is required to provide to move Satellite out of its orbit
A distance of d is covered with 53 mile/hr initially.
Time taken to cover this distance t1 = d/53 hour
Next distance of d is covered with x mile hours.
Time taken to cover this distance t2 = d/x hours.
We have average speed = 26.5 mile / hour
= Total distance traveled/ total time taken
=
False, There are no genetics that can save you from constant overeating and there are no genetics that can prevent you from working out, at least to your possible extent.
Answer:
440J
Explanation:
First, let us find the <u>weight </u>of the barbell.
The formula to find the weight is :
W = m × g
Here,
m ⇒ mass ⇒ 20 kg
g ⇒ acceleration of gravity
<u>Let us find it now.</u>
W = m × g
W = 20 kg × 10 ms⁻²
W = 200N
And now let us find<u> the work done by this weight lifter.</u>
Work = Force × Displacement
<u>Let us find it now.</u>
Work = Force × Displacement
= 200N × 2.2m
=<u> 440J</u>
Answer:
A
Explanation:
Light has both wave and particle characteristics. It behaves as wave in examples such as Reflection, refraction, diffraction, interference. It behaves as a particle in photoelectric effect, compton's effect etc. Light is an example of wave-particle duality.
