Given:
\[ P = 25 \, \text{watts} \]
\[ W = 5000 \, \text{joules} \]
Find the time \((t)\).
Answer (3)
P = W/t 25 = 5000/t 25t = 5000 t = 5000/25 = 200 watt.
The question asks us to find the time (t) it takes for a device with a power (P) consumption of 25 watts to use an energy (W) of 5000 joules. The relationship that connects these quantities is given by the equation P = W/t , which means power is the rate at which energy is used over time. To find the time, we can rearrange this formula to solve for t , which is t = W/P .
Using the provided values:
P = 25 watts
W = 5000 joules
Time ( t ) can be calculated as follows:
t = W / P = 5000 joules / 25 watts = 200 seconds.
So, the device will take 200 seconds to use 5000 joules of energy.
The time it takes for a device using 25 watts to consume 5000 joules of energy is 200 seconds. This is calculated using the formula t = P W . By substituting the given values, we find that t = 200 s .
