It's true, when we lift an object we add energy to it.
because, when we lift an object by applying force , the object attains a height and hence the energy gets stored in it, in the form gravitational potential energy .
The correct answer to the question is 8.33 minutes.
CALCULATION:
The distance of earth from sun s = 150 million km.
We know one million = 10 lakh = 
Also 1 km = 
Hence, the distance s = 
= 
The speed of light c = 300,000 km per second
= 
We are asked to calculate the time.
The time of the reaching earth is calculated as -




We know one minute = 60 second.
Hence, 500 seconds = 
=
[ans]
Answer:
2.2 s
Explanation:
Hi!
Let's consider the origin of the coordinate system at the ground, and consider that the clam starts with zero velocity, the equation of motion of the clam is given by

We are looking for a time t for which x(t) = 0

Solving for t:

Rounding at the first decimal:
t = 2.2 s
Answer:
A
Explanation:
A circle graph typically represents numbers in percentages, used to visualize a part to whole relationship or a composition
Answer:
Explanation:
The processes involved in each of the molecules involved are different.
For example, water molecules that have condensed in the atmosphere (in the cloud) return back to the earth through precipitation in the form of rain water. These cows drink these water from various water bodies around them. This is one process in which water molecules move from the atmosphere into the living cow.
In the case of carbon and nitrogen atoms; the air the cow breath in consists of nitrogen, oxygen, carbon dioxide and some other gases. These gas molecules move (from the atmosphere) into the cow through the process of respiration.
