Answer:
formula
ΔP= PgΔh
Explanation:
Calculation.
ΔP = (1.05 x 10^3kg/m^3)(9.8m/s^2)(6ft equivalent to 1.8288m)
ΔP = 1.05 x 10^3 kg/m^3 x 9.8m/s^2.
x1.8288.
ΔP = 1.88 x 10^4 Pa.
Period = 6 seconds and
.
<u>Explanation:</u>
We have , the motion of a swing that requires 6 seconds to complete one cycle. Period is the amount of time needed to complete one oscillation . And in question it's given that 6 seconds is needed to complete one cycle. Hence ,Period of the motion of a swing is 6 seconds . Frequency is the number of vibrations produced per second and is calculated with the formula of
. SI unit of frequency is Hertz or Hz. We know that time period is 6 seconds so frequency =
⇒ 
⇒ 
⇒ 
Therefore , Period = 6 seconds and
.
Answer:
Since velocity is a speed and a direction, there are only two ways for you to accelerate
Explanation:
change your speed or change your direction—or change both.
