Produce power through the circuit.
Answer:
yes
Explanation:
velocity changes either in magnitude (an increase or decrease in speed) or in direction, or both
The power exerted by the cyclist is determined as 50 W.
<h3>
Average power exerted by the cyclist</h3>
The power exerted by the cyclist is calculated as follows;
P = FV
where;
- F is the applied force
- V is velocity
P = 20 x 2.5
P = 50 W
Thus, the power exerted by the cyclist is determined as 50 W.

Answer: a) 152 cm
b) 0.725 ms
c) 10°
Explanation:
Given
Frequency of the wave, f = 524 Hz
Speed of the wave, v = 345 m/s
Wavelength of the wave, λ = ?
The relation for wavelength is given by
λ = f/v, on substituting
λ = 524 / 345
λ = 1.52 m or 152 cm
T = 1/v
T = 0.0029 s
T = 2.9 ms.
Note that the phase change is 90°, thus the time required to change the phase by 90° is
t = 2.9 * (90 / 360)
t = 2.9 * 0.25
t = 0.725 ms
The phase difference at a particular instance 4.4 cm apart is
= (4.4 / 152) * 360
= 0.02895 * 360
= 10.422°
a) 152 cm
b) 0.725 ms
c) 10°
Angle is 31 adding all sides
