Answer:
Length/time
Explanation:
As in the definition...Velocity is the rate of change of displacement...so hence
Velocity = Displacement/Time...where Displacement is length
Velocity = Length/Time
A neutron star has more mass than a bowling ball,
and is about the same size as Chicago.
Supposing the runner is condensed to a point and moves upward at 2.2 m/s.
It takes a time = 2.2/g = 2.2/9.8 = 0.22 seconds to increase to max height.
Now looking at this condition in opposite - that is the runner is at max height and drops back to earth in 0.22 s (symmetry of this kind of motion).
From what height does any object take 0.22 s to fall to earth (supposing there is no air friction)?
d = 1/2gt²= (0.5)(9.8)(0.22)²= 0.24 m
Answer:
Option B: Increase the voltage, while keeping the resistance constant.
Explanation:
Current is directly proportional to voltage, but indirectly proportional to resistance.
Answer:
0.26seconds
Explanation:
Impulse is the product of force and time
Impulse =Force * Time
Given
Impulse = 67Ns
Force = 257N
Required
Time
From the formula;
Time = Impulse/Force
Time = 67/257
Time = 0.26s
Hence the amount of time is 0.26seconds
