Answer:
Energy stored in an object due to its position is Potential Energy. · Energy that a moving object has due to its motion is Kinetic Energy.
Explanation:
95% postive the answer for this question is D. How it allows the purchaser to listen to music anywhere
According to Newton;s Second Law of motion, F = ma. Acceleration is the change of velocity per unit time. Since there is no change of velocity, then acceleration is equal to zero. Consequently, the net force F is also equal to zero. The net force is equal to the sum of all the forces acting on the body. These forces are the horizontal force and the frictional force. They are acting in opposite directions. So, the sum must be
F = 0 = Horizontal - Frictional
0 = 100 N - Frictional
Frictional force = 100 N
The equilibrium constant is a quantity which characterizes an equilibrium in a reaction
.
Explanation:
- The equilibrium constant is a quantity which characterizes an equilibrium in a reaction
- it is based on the final concentrations of involved compounds.
- The value is constant for all of the experiments .
- It should be consistent because this constant is defined to be the relation between all concentrations of involved compounds at
chemical equilibrium.
C. Use Coulomb's law F=kq1q2/r^2, where q1 and q2 are the two charges, and r is the distance between the two. Plug in q1=0.0072 C, q2=-0.0060 C, r=0.0040 m, k is the constant 9*10^9 N, F=-2.4*10^10 N, so the answer is C.
