Answer:
4.096 kW
Explanation:
Applying,
P = Fvcos∅................. Equation 1
Where P = Power of the motor, F = Force exerted on the motor, v = Velocity, ∅ = angle.
From the question,
Given: F = 500 N, v = 10 m/s, ∅ = 35°
Substitute these values into equation 1
P = 500×10×cos35°
P = 4095.8 W
P = 4.096 kW
Hence the power rating of the moto in kW is 4.096 kW

Answer:
Explanation:
Work done by mountain climber against his weight
= mgH
= 70.5 X 9.8 X 365
= 252178.5 J
Power = work done / time taken to do work
= 252178.5 / (49 x 60 )
= 85.775 J/s
= 85.775 W .
Answer:
the middle
Explanation:
the left one bulb gets power from the outher bulb
the one on right has more bulbs
Answer: The new gas pressure is 150 kPa.
Explanation :
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
where,
= initial pressure of gas = (100+200) kPa = 300 kPa
= final pressure of gas = ?
= initial volume of gas = v
= final volume of gas = 2v
Therefore, the new gas pressure is 150 kPa.
