Answer:
156.8 Watts
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 10 kg
Height (h) = 8 m
Time (t) = 5 s
Power (P) =?
Next, we shall determine the energy used by the motor to raise the block. This can be obtained as follow:
Mass (m) = 10 kg
Height (h) = 8 m
Acceleration due to gravity (g) = 9.8 m/s²
Energy (E) =?
E = mgh
E = 10 × 9. 8 × 8
E = 784 J
Finally, we shall determine the power output of the motor. This can be obtained as illustrated below:
Time (t) = 5 s
Energy (E) = 784 J
Power (P) =?
P = E/t
P = 784 / 5
P = 156.8 Watts
Therefore, the power output of the motor is 156.8 Watts
Answer:
The force of gravity is not the same as being on the earth. when your on the earth there no gravitational pull its all up to the air

Answer:
the answer would be microwelds.
i’m not 100 percent sure but I need points to ask questions good luck th
1. Magnets attract iron and other ferromagnetic materials such as neodymium and cobalt.
2. Magnets attract or repel other magnets.
3. In addition one part of a magnet will always point north when allowed to swing freely.
