Chapter 10: Q.37 (page 257)

A system loses400J of potential energy. In the process, it does 400J of work on the environment and the thermal energy increases by 100J. Show this process on an energy bar chart.

Short Answer

Expert verified

The process on the energy bar chart is given below,

Step by step solution

01

Potential energy : 

Potential energy is the amount of energy stored by an object as a result of its position in relation to other objects, internal tensions, electric charge, and other variables.

02

Explanation : 

Potential energy loss PE=-400J

Work doneW=400J

Thermal energy increase U=100J

The energy bar's process implies that energy is conserved. This energy at the start of the process is the same as the energy at the end.

As a result, the total energy after the procedure is,

∆Eth=400-400+100=100J

The process on the energy bar chart is,

A process occurs in which a system’s potential energy increases while the environment does work on the system. Does the system’s kinetic energy increase, decrease, or stay the same? Or is there not enough information to tell? Explain.

An object moving in the xy-plane is subjected to the force F→=(2xyı^+3yȷ^)N, where x and y are in m.

a. The particle moves from the origin to the point with coordinates (a,b)by moving first along the x-axis to (a,0), then parallel to the y-axis. How much work does the force do?

b. The particle moves from the origin to the point with coordinates (a,b)by moving first along the y-axis to (0,b), then parallel to the x-axis. How much work does the force do?

c. Is this a conservative force?
