I would say 2 but I don’t want to get you wrong
Answer:
400watts
Explanation:
Power is defined as the amount of energy expended in a specific time. It is also defined as the change in work done with respect to time.
Mathematically,
Power = Workdone/time
Work done = Force×distance
Power = Force × Distance/Time
Given force = mass× acceleration due to gravity
Force = 60×10 = 600N
Distance covered = 4.0m
Time taken = 6.0seconds
Power expended = 600×4/6
Power expended = 400Watts
The average mechanical power (in W) required to do this is 400Watts
He must throw the device AWAY from the ship.
Since momentum is conserved, that move will give HIM an equal amount of momentum TOWARDS the ship.
Answer:
Doubling the amount of charge on one of the particles.
Explanation:
The force between two charges is given by :
Where
r is the distance between charges
or
On doubling the charge on one of the particle,
F' = 2F
So, the force gets doubled. Hence, the correct option is (d).
Answer:
Earth's tilted axis
Explanation:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays.
