Answer:
A. increase the speed
Explanation:
For you to be able to shorten the time it takes for the care to get to its destination, you must increase the speed because if the distance is the same that means you have to increase your speed.
Answer:
-39.2m/s
Explanation:
Using the equation of motion;
v = u + at
Since the ball is thrown upward, the acceleration due to gravity acting on it will be negative, hence a = -g
v = u - gt
Since g = 9.8m/s²
t = 4.0s
u = 0m/s
v = 0 + (-9.8)(4)
v = 0 + (-9.8)(4)
v = -39.2m/s
Hence the speed of the ball before release is -39.2m/s
Answer:
Explanation:
The first derivative of the angular momentum with respect to time is defined as the magnitude of the average torque acting on the particle:
So, we calculate the magnitude of the average torque, dividing the change of the angular momemtum into the time:
You would do the √molar mass B (neon) over √molar mass A (hydrogen)
√20/√2 = 3.16
