Answer:
Gravity: downwards
Air drag and air-pressure on the inner surface of the the parachute: Upwards
Explanation:
- If a sky-diver is in the final stages of his descend with open parachute such that the wind is calm and it does not blows him laterally.
- In such a condition the air resistance in the form of drag and the pressure force due to the air captured in the parachute are acting in the upward direction which balance the force of gravity on the body. But this situation may occur momentarily and then again the diver must begin to slowly descend.
Answer:
Explanation:
We are given that
When d=3 m
We have to find the intensity when the distance from the light bulb is 2 m away.
According to question
Intensity,
Where k=Proportionality constant.
Substitute the values
Intensity when d=2 m
In the veeeery distant future, our sun will transform into a red giant, and in the even more distant future, it will become a white dwarf.
Answer:
If the force is doubled, then the acceleration would also double since F-net = ma. In this case, the acceleration would be 1 m/s per second.
