Answer: Sprinter's average acceleration = 
Explanation:
The formula for the average acceleration is given as follows:
--- (A)
Where,
= Final velocity = 
= Initial velocity = 
= Elapsed time = 10 seconds
Plug the values in equation (A):
Therefore, the sprinter's average acceleration is .
Answer:
1.09 km, 3 km
Explanation:
displacement, d = 3.20 km at 20° North of east
A vector quantity has two components one along the x axis and the other is along Y axis. the component along X axis is called the horizontal component and it is due east.
The component along y axis is called vertical component and it is due North.
Displacement due North, dy = 3.20 Sin 20° = 1.09 km
Displacement due east, dx = 3.20 Cos 20° = 3 km
yes if it was submerged long enough
Answer:
I think it is the last one
Hot air rising and cool air sinking.
Explanation:I am not 100% sure. I just think the hot air rises bc evaporation.
Good luck. : )
