Yes, eg., when 2 bodies move in opposite directions
, the relative velocity of each is greater than the individual velocity of either
Answer:
The distance traveled by the woman is 34.1m
Explanation:
Given
The initial height of the cliff
yo = 45m final, positition y = 0m bottom of the cliff
y = yo + ut -1/2gt²
u = 20.0m/s initial speed
g = 9.80m/s²
0 = 45.0 + 20×t –1/2×9.8×t²
0 = 45 +20t –4.9t²
Solving quadratically or by using a calculator,
t = 5.69s and –1.61s byt time cannot be negative so t = 5.69s
So this is the total time it takes for the ball to reach the ground from the height it was thrown.
The distance traveled by the woman is
s = vt
Given the speed of the woman v = 6.00m/s
Therefore
s = 6.00×5.69 = 34.14m
Approximately 34.1m to 3 significant figures.
Answer:
electrons will migrate untill there is uniform distribution of charge .
and sphere became uniformly charged
Explanation:
as conducting sphere is charged positively it is given . the left side of sphere is charged positively . there is negative charge on the left side that will be attracted by positive charge of right side .
therefore electrons from left side will start migrate towards right side due to attraction of positive charge of right side .
therefore electron will start migrate uniformly .
electrons will migrate untill there is uniform distribution of charge .
and sphere became uniformly charged
Answer:
a = 9.8 m/s²
Explanation:
Acceleration due to gravity on Earth is constant, which is 9.8 m/s²
