Answer:
20.25 W
Explanation:
Applying,
P = I²R.................... Equation 1
Where P = Power, I = current drawn by the test light, R = Resistance of the test light
From the question,
Given: I = 1.5 A, R = 9.00 Ω
Substitute these values into equation 1
P = (1.5²)(9)
P = 2.25×9
P = 20.25 W
A pie graph is the graph used to show how a part of something relates to the whole.
Answer:
19.39mph
Explanation:
To calculate speed, the formula; distance (d)/time(t) is used.
In this question, a distance of 40yards and a time of 4.22seconds is given. We need to convert the distance to miles and time to hours.
If 3600s = 1 hr
Then 4.22s will be 4.22/3600 hours
= 0.001172hours.
If 1760 yd = 1 mile
Then 40 yd will be 40/1760 miles
= 0.02272miles
Hence, the speed in miles per hour (mph) = 0.02272miles ÷ 0.001172hours
= 0.02272 ÷ 0.001172
= 19.38566
= 19.39
Therefore, the speed of the player is 19.39 miles per hour (mph).
