I would have to say B failed because I think I read something about it being only 2law not 3
Answer:
Her average speed is 5 miles per hour.
Explanation:
Average speed is the ratio of total distance travelled in particular time.
The park's pond is 0.5 miles around.
She can swim 20 laps, it means she can swim total = 20 × 0.5
= 10 miles.
Time taken by her to complete the track = 2 hour
Now, Average speed =
=
= 5 miles/hour.
Answer:
960 Watt
Explanation:
From the question,
Electric power = Voltage squared/Resistance
P = V²/R ..................... Equation 1
Where P = power, V = Voltage, R = Resistance
Given: V = 120 volts, R = 15 ohms.
Substitute these values into equation 1
P = 120²/15
P = 14400/15
P = 960 Watt
