D none of the above
all of them is related to energy and motion , not to positioning.
Answer:
b)
movement creates a difference in air pressure.
as warm air rises up it creates a vaccum so due to that the pressure in that region decreases.
Answer:
W = 0 J
Explanation:
It is given that,
Weight of the crate, W = 100 N
Distance moved by the crate, d = 1.5 m
Let W is the work done to hold the crate 1.5 m above the ground in this way. It is given by the product of force and the displacement. Its formula is given by :

Here,
as it is lifted vertically
W = 0
So, the work done to hold the crate is 0. Hence, this is the required solution.
The correct answer for this question would be option A. When the thermal energy in a hot iron flows into a shirt, what we can possibly say about this situation is that, the iron is warmer than the shirt. The transfer of heat from the iron to the shirt is called heat conduction. Hope this answer helps.
