Answer:
solar panels exposed in the sun and also charging electric circuit
The formula we can use in this case is:
d = v0t + 0.5 at^2
v = at + v0
where,
d = distance travelled
v0 = initial velocity = 0 since at rest
t = time travelled
a = acceleration
v = final velocity when it took off
a. d = 0 + 0.5 * 3 * 30^2
d = 1350 m
b. v = 3 * 30 + 0
<span>v = 90 m/s</span>
Answer:
Airplane cabins are pressurized because as the airplane climbs higher in altitude, the air becomes very thin, this pressurization ensures that there is still enough breathable oxygen in the cabin to prevent everyone from suffering the effects of hypoxia and passing out.

Conservation of energy just means that the total energy is unchanged.
Energy is made up of potential and kinetic, so if the total is unchanged, that means the sum of them is unchanged, which is D.
Answer:
Explanation:
Ratio of the largest amplitude to the smallest amplitude is called voltage standing wave ratio ( along a transmission line )
<u>Determine the ratio of the largest such amplitude noted by an observer tot the smallest amplitude </u>
Expression for VSWR
VSWR = where ; Pr = reflected power , Pi = Incident power
hence the ratio of the largest amplitude to the smallest amplitude
= = where ; Ei = amplitude of incident wave, Er = amplitude of reflected wave
