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
The term climate change encompasses global warming, but refers to the broader range of changes that are happening to our planet. , These broader climate changes include: rising sea levels, shrinking mountain glaciers, accelerating ice melt in Greenland, Antarctica and the Arctic, and shifts in flower and plant blooming times.
Answer:
The magnitude of the electric field is 
in the r direction.
Explanation:
The equation of the electric field is given by:
Where:
- k is the Coulomb constant is
- q is the charge
- r is the distance from A to q
Therefore, the magnitude of the electric field is in the r direction.
I hope it helps you!
Answer:
a) 70,560 J
b) 88.2 N/m
Explanation:
The spring potential will equal the change in gravity potential
PS = PE = mgh = 80(9.8)(100 - 10) = 70,560 J
PS = ½kx²
k = 2PS/x² = 2(70560)/(100 - 50 - 10)² = 88.2 N/m
Answer: It opposes the flow of electrons.
