Drop "moves" from the list for a moment.
You can also drop "stops moving", because that's included in "changes speed"
(from something to zero).
When an object changes speed or changes direction, that's called "acceleration".
I dropped the first one from the list, because an object can be moving,
and as long as it's speed is constant and it's moving in a straight line,
there's no acceleration.
I think you meant to say "starts moving". That's a change of speed (from zero
to something), so it's also acceleration.
C. Chemical Energy is transformed to light energy and heat energy. The heat energy is keeping you warm and light energy is giving you the light you need to be able to read the book.
A battery is a real-life voltage source. A battery can be thought of as a perfect voltage source with a small resistor (called internal resistance) in series. ... The terminal voltage equals the emf minus the voltage drop across the internal resistance (current of the external circuit times the internal resistance.)
Answer:
175J
Explanation:
Work done is given by the product of the force applied and the distance travelled as a result of that force.
Or in formula , W=F×d
Thus,
W= 35 × 5.0=175 J or 1.8 e2 J
