Option D
The resistance in machine is 8.5 ohms
<em><u>Solution:</u></em>
Given that,
Power = 1700 W
Voltage = 120 V
We have to find the resistance in machine
<em><u>The formula used is:</u></em>
Where,
"P" is the electric power and "V" is the voltage and "R" is the resistance
<em><u>Substituting the given values we get,</u></em>
Thus resistance in machine is 8.5 ohms
There's no such thing as "an unbalanced force".
When the entire group of forces acting on an object is unbalanced,
meaning that the net force on the object is not zero, then the object
moves with accelerated motion . . . it may speed up, it may slow down,
or its speed may remain constant while its direction changes.
Answer:
It is a law of mechanics and physics discovered by Robert Hooke. This theory of elasticity says the extension of a spring is proportional to the load applied to it. Many materials obey this law as long as the load does not exceed the material's elastic limit.

Answer:
Explanation:
These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.
Answer:
<h2>B) Newton's 2nd law</h2>
Explanation:
<h2>From; force= mass × acceleration </h2><h2> f= m×a </h2><h2>where a(acceleration)= velocity/time</h2><h3> force = mv/t</h3><h3>But momentum(p) = Mass × velocity </h3><h2>hence force =p/t </h2><h3>that is Momentum = force × time ( Newton's 2nd law)</h3>
