Answer:
the solid particles that settle down at the bottom of the container are known as sediment.
Explanation:
"Q = ΔU + W" is the equation is used to solve the questions related to "First law of thermodynamics".
<h3> What is the first law of thermodyanamics?</h3>
"First law of thermodynamics" states that "energy" neither created nor destroyed, but it can transfer from "one form of energy" to "another form of energy".
This "First law of thermodynamics" is also called as "law of conversation of energy". The formula for "First law of thermodynamics" of a system is that "change in internal energy of a system" is same as the difference of "heat energy" flows across the " boundaries of a system" and the "work done" on the system.
ΔU = Q - W
Q = ΔU + W
Where, "ΔU" is "change in internal energy", "Q" is "heat transferred and "W" is "work done.
Hence "Q = ΔU + W" is the equation is used to solve the questions related to "First law of thermodynamics".

Answer: 5.5 mass
Explanation: The force of gravity pulling the car up the hill = 5.5
Answer:
a) Is in the same direction.
Explanation:
Since on both cases the wheel is rotated at a constant angular speed the acceleration will only be the centripetal one, which, as the name implies, will be directed at the center of the wheel, so it will point in the same direction on both situations.
Answer:
Heat sink is a heat exchanger used to transfer heat generated by a mechanical or an electronic device to the surroundings. Heat sinks are either made up of aluminium or copper or any other material which is good conductor of heat. Because conductor helps in conduction of heat from heated surface to the outside air.
