Answer:
A. A potential energy function can be specified for a conservative force.
TRUE
because there is no loss of energy in conservative type of forces.
B. A nonconservative force permits a two-way conversion between kinetic and potential energies.
FALSE
It is not true because energy is not conserved in non-conservative forces.
C. The work done by a nonconservative force depends on the path taken.
TRUE
It depends on total path length while in conservative it only depends on initial and final state
D. A potential energy function can be specified for a nonconservative force.
FALSE
Since energy is not stored in non-conservative forces so it is not defined for non conservative forces
E. A conservative force permits a two-way conversion between kinetic and potential energies.
TRUE
Work done against conservative forces is stored in form of potential energy so it is possible to have two way conversion.
F. The work done by a conservative force depends on the path taken.
FALSE
Conservative force work depends only on initial and final state
Answer:
1. Torque → F. Study of forces
2. C.O.G → D. Point of action of weight.
3. Plumb line → A. Line of C.O.G
The answer would be half court I think
Object B is positively charged, Object C is negatively charged, Object D is negatively charged.
Answer: Gravity has an effect of a gravitational pull, which keeps things on the ground instead of floating around like we are in space.
