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
In hydrosphere, the parameter surface temperatures does not change from low latitude to high.
Answer: Option B
<u>Explanation:</u>
Hydrosphere is made with all available water on earth, sea, planets and lakes. Its role is to sustain water various life and maintaining ecosystems. Water is present in high percentage on the earth's.
Comparing surface temperatures and lower temperatures in high latitude areas, lower sea surface temperatures found at high latitudes. In the deeper ocean, the water temperature is similar to the surface temperature, keeping the curve vertically. Hence, there is no rapid changes in the temperature with depth (remains constant).
The total resistance for resistors in series is the sum of the individual resistances.
The total resistance is 650 ohm + 350 ohm + 1000 ohm = 2000 ohm
