On or near the surface of the Earth, 1 newton is the weight of about 102 grams of mass.
Note that the gravitational force between the object and the Earth is always the
same. It doesn't matter whether the object is falling, flying, floating, fluttering,
rising, sinking, rolling, sliding, or just laying there. It doesn't change.
Answer:
The velocity of ball and man after catching ball is
Explanation:
Since there is no friction and no external force the momentum is conserved .
Here when man catches ball then man and ball move with common velocity .
Let the final common velocity be ,
Given that mass of the ball is =
Given that mass of man is
Initial velocity of ball =
Now considering momentum conservation
Answer:
False
Explanation:
A Larger pulse with more energy means that the wave has a large amplitude. As in the given question, both the waves are travelling in the same medium, hence their speeds will remain the same and therefore the larger pulse will not overtake the smaller pulse. Remember the amplitude of a wave does not affect the speed at which the wave travels.
