This relationship was first published by Sir Issac Newton. His law of universal gravitation says that the force (F) of gravitational attraction between two objects with Mass1 and Mass2 at distance D is: F = G(mass1*mass2)/D squared
Answer: <em><u>A</u></em><em><u>. The current in a 60-Watt bulb plugged into a 120-Volt outlet is 0.5 A. </u></em>
<em><u>I = P / V = (60 W) / (120 V) = 0.5 A</u></em>
<h3>
<u>For each problem, use the P = V • I equation to solve for the unknown quantity. In a, b, and e, the unknown quantity is current (I); and in c and d, the unknown quantity is power (P).</u></h3>
Other answers:
b. The current in a 120-Watt bulb plugged into a 120-Volt outlet is 1.0 A.
I = P / V = (120 W) / (120 V) = 1.0 A
c. The power of a saw that draws 12 amps of current when plugged into a 120-Volt outlet is 1440 W.
P = V • I = (120 V) • (12 A) = 1440 W
d. The power of a toaster that draws 6 amps of current when plugged into a 120-Volt outlet is 720 W.
P = V • I = (120 V) • (6 A) = 720 W
e. The current in a 1000-Watt microwave when plugged into a 120-Volt outlet is 8.3 A.
I = P / V = (1000 W) / (120 V) = 8.3 A
The area under the curve of a velocity-time graph gives us the <u>position of an object</u> to find the object's <u>displacement</u> specifically.
Therefore, <u>A: Position of an object</u> is the correct answer.
The simplest device to accomplish that process is a transformer.
