If a light bulb's power rating is 75w, it means it consumesjoule of electric energy in 1 second of time

Electrical energy consumed, E = 1.95 × 10⁻⁵ kWh  

Explanation:

It is given that,

Power rating on the light bulb, P = 75 W

We need to find the electrical energy consumed by the bulb in 1 second of time i.e in 0.00026 hours.

Energy consumed, E = P × t

E = 75 W × 0.00026 h

E = 0.0195 W-h

Energy consumed is calculated in kilo watt hour. Since, 1 watt = 0.001 kW

So, E = 1.95 × 10⁻⁵ kWh  

Hence, this is the required solution.

answer: cesare beccaria developed the classical school of criminology with from philosopher jeremy bentham

explanation:

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
