Answer:
8.75 m/s^2
Explanation:
initial speed, u = 300 m/s
final speed, v = 400 m/s
distance, h = 4 km = 4000 m
Let a be the acceleration of the plane.
Use third equation of motion
a = 8.75 m/s^2
Thus, the acceleration of the plane is 8.75 m/s^2.
Answer: Option B) Power
Explanation:
Power is the rate at which energy is expended per unit time. Hence, the rate at which electric energy is used is simply called electrical power.
Mathematically, the relationship between energy and power is:
Power = (Electrical energy /Time)
Hence, power consumption or electrical energy used in homes is rated in kilowatt per hour (kWh).
