Answer:
a. the amount of work done on a system is dependent of pathway
Explanation:
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system.
ΔU = Q - W
Where;
Q, the net heat transfer into the system depends on the pathway
W, the net work done by the system also depends on the pathway
But, ΔU, the change in internal energy is independent of pathway
Therefore, the correct option is "A"
a. the amount of work done on a system is dependent of pathway
That symbol represents a source of DC, usually a battery.
The zig-zag line represents a resistor, and the two little circles
connected by a short line represent a switch in the closed position.,
Main answer- the velocity of 2.2kg ball is 12.566m/s
supporting answer- In circular motion the velocity is termed as angular velocity
Angular velocity represents the rate of variation of an object's position angle with respect to time.
W =theta/ time
W = length of the arc/ radius of circle × time
body of the answer-2πr/r×t =2π/t
2×π/ 0.5 = 12.566 m/s
final answer- hence the velocity of ball is revolving is 12.566 m/s

Answer:a means of solving a problem or dealing with a difficult situation.
Explanation:Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture. Let's make use of our salt water example to talk about the two main parts of a solution.
