Answer:
0.0083km or 8.3m
Explanation:
Given parameters:
Distance = 5km
Time = 10min
Unknown:
Distance moved in 1sec = ?
Solution:
To solve this problem, let us first find the speed of the motorbike.
Speed =
Speed = = 0.5km/min
So;
In 1sec:
60 sec = 1 min
1 sec = min
Distance moved in 1sec = speed x time
Distance moved = 0.5km/min x min = 0.0083km or 8.3m
Answer:
The answer is B
Explanation:
The absorption happens when photons from light hit atoms and molecules, and they vibrate because of that specific interaction. Then the heat ejects from the object in the format of thermal energy.
a/b. The ball has velocity vector at time
where is the ball's initial speed and .
c. At its highest point, the ball has 0 vertical speed. This occurs when
d. Recall that
so that at its highest point,
e. This is just twice the time it takes for the ball to reach its maximum height, .
f. The ball's horizontal position after time is
so that after the time found in part (f), the ball has traveled
