Answer:
Explanation:
P = 1.84 x 10³ N / 1.20² m² = 1,277.77777... N/m²
P = 1.28 x 10³ Pa
Answer:
3.78 kWh
Explanation:
Power of incandescent bulb = 60 W = 0.06 kW
Power of fluorescent bulb = 15 W = 0.015 kW
Number of hours in a week if each day the light is turned on 12 hours
12×7 = 84 hours
Difference in power
0.06-0.015 = 0.045 kW
Multiplying with the number of hours
Hence, the fluorescent bulb will consume 3.78 kWh less electricity energy than the incandescent bulb.
Answer:
All objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.
