Answer 1

Answer on Question #47911, Physics, Mechanics | Kinematics | Dynamics

an electric bulb of 60 W is used for 6 hour per day. calculate the units of energy consumed in one day by the bulb.

Solution:

$t = 6$ hour $= 6 \cdot 3600s$ - time;

$P = 60W$ - power;

The formula for the power:

$$Power = \frac{Energy}{time}$$ $$Energy = time \cdot Power = 6 \cdot 3600s \cdot 60W = 1.296 \cdot 10^6 J$$

Answer: energy consumed in one day: $1.296 \cdot 10^6 J$
