Answer:
208.33 W
141.26626 seconds
Explanation:
E = Energy = 
t = Time taken = 8 h
m = Mass = 2000 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Height of platform = 1.5 m
Power is obtained when we divide energy by time
The average useful power output of the person is 208.33 W
The energy in the next part would be the potential energy
The time taken would be
The time taken to lift the load is 141.26626 seconds
<span>Pice=920kg/m^3
deltaP=PgH=920kg/m^3 X 9.80665m/s^2 X 1000m = 9022118 Pa
P=Po + deltaP=101.325 + 9022 = 9123kPa</span>
The correct answer is visible light.
Hope this helps.
To answer this question we subtract the initial velocity from her final velocity. On the starting blocks the initial velocity was 0 m/s. Her final velocity was 11 m/s.t = 11m/s - 0 m/s, so the change in velocity is 11m/s. Time was 5 seconds.Plug it into the formula: 11 m/s ÷ 5 s= 2.2 m/s<span>2</span>
Answer:
230.53°
Explanation:
α = angle in rad / t^2
t =2mins = 2 × 60 = 120sec.
α = angle in rad / 2^2
α = angle in rad / 16
15+4(2) = angle in rad /4
23 = angle/4
23× 4 = angle in radian
92 = angle in radian
But π rad = 180°
1 rad = 180 /π
Therefore
92 rad = 92 ×180/π = 5270.53°
This value is far more so we subtract from 360° continuously till we get a value less than 360°
5270.53- (360×14) =5270.53- 5040
230.53°
