Question

W mg, where mis mass of an object and g is
acceleration due to gravity of that planet.
For Earth, g -9.8 m/s For Mars, g 3.7 m/s?
As the value of g for Earth and Mars are different, the
weight of an object on them will be different.
Weight of object on mars will be less than that on earth.
(b) What are i) Free fall (n) Acceleration due to
gravity (il) Escape Velocity (iv) Centripetal force.
Ans. ) Free fall - When the object moves under the
influence of the force of gravity alone, it is said to be in a
tate of free fall
During free fall (o) Initial velocity u=0. (ii) Force acting
en object is only gravitational force. (iii) Acceleration
eroduced is a 8-9.8m's. (iv) Frictional forces and
ugyant forces due to air or surrounding are absent.​

Answer 1

Answer:

Putting out a candle may not seem like a task that requires much explanation, but you might be surprised at how many different ways there are to do it, and the effects each has on the life of the candle. Should you simply blow out the flame, or is it better to use another object to stifle it? Is it safe to use your fingers if there’s nothing else around? The short answer is that different methods will work best for different purposes.
