plz mark me as brainliest :)
Answer:
P = 11666.6 W
Explanation:
Given that,
Work done by the motor, W = 3500 kJ
Time, t = 5 min = 300 s
We need to find the power developed by the motor. Power developed is given by :
![P=\dfrac{E}{t}\\\\P=\dfrac{3500\times 10^3}{300}\\\\P=11666.7\ W](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BE%7D%7Bt%7D%5C%5C%5C%5CP%3D%5Cdfrac%7B3500%5Ctimes%2010%5E3%7D%7B300%7D%5C%5C%5C%5CP%3D11666.7%5C%20W)
So, the required power is 11666.6 W.
the correct one is not on here but if there is no more choices then it is the first one
The term that describes the direction closest to the point of origin is Proximal. Dorsal is the directional term for the movement toward the back of the body. Cephalic is the term that describes the movement towards the top of the body. Ventral on the other hand describes the movement toward the front of the body.
Answer:
Explanation:
A ) Index of refraction = real depth / apparent depth
real depth = 7.8 cm ; Index of refraction = 1.33
1.33 = 7.8 /apparent depth
apparent depth = 7.8 / 1.33
= 5.86 cm
B )
Distance of fish fro mirror = 20.6 - 7.8 = 12.8 cm
Image will be formed 12.8 cm behind the mirror.
Distance of image from the water surface = 20.6 +12.8
= 33.4 cm
Real depth of image = 33.4
Apparent depth of image = 33.4 / 1.33
= 25.11 cm
