Answer:
Explanation:
Given:
- mass of water,
- initial temperature of water,
- final temperature of water,
- specific heat of water,
<u>Now the amount of heat energy required:</u>
Since all of the mechanical energy is being converted into heat, therefore the same amount of mechanical energy is required.
A). m/s ... meters per second.
That's a speed.
b). m/s² ... (meters per second) per second.
Acceleration.
c). m²/s ... square meters per second.
Rate of change of area.
Meaningless unit, unless you happen to be
a painter of houses or a mower of lawns.
d). kg-m/s² ... (mass) x (an acceleration).
This is a unit of force.
In fact, it's the definition of "newton".
Answer. dry friction- <span> resists relative lateral motion of two solid surfaces in contact.</span>
A). Both the energy and the wave travel in the same direction.
If they didn't, they'd wind up in different cities almost instantly.
The potential difference across 3 Ohm resistor is 20V.
The resistors are connected in parallel which means all the three resistances have a fully potential difference of 20V.
