Answer:

2.3s

Explanation:

The total time in flight is 2.3s.

Therefore, the time it takes the canon ball to reach its peak is also the total time of flight is 2.3s.

  • Time is the duration of travel of a body.
  • The amount of time spent during flight of the canon ball is 2.3s.

Two spherical conductors are separated by a distance much larger than either of their radii. Sphere A has a radius of 11.5 cm an
bonufazy [111]

Explanation:

As the given spheres are connected by a thin wire so, the potential on the spheres are the same.

          \frac{q_{1}}{r_{1}} = \frac{q_{2}}{r_{2}} ......... (1)

Hence, total charge will be as follows.

              q_{1} + q_{2} = Q = -95.5 nC .......... (2)

Using the above two equations, the final equation will be as follows.

          q_{2} = \frac{Qr_{2}}{r_{1} + r_{2}}

and,    q_{1} = \frac{Qr_{1}}{r_{1} + r_{2}}

Hence, we will calculate the charge on sphere B after the equilibrium is reached as follows.

          q_{2} = \frac{Qr_{2}}{r_{1} + r_{2}}

                     = \frac{-95.5 \times 74.4 cm}{(11.5 + 74.4) cm}

                     = 82.714 nC

Thus, we can conclude that the charge on sphere B after equilibrium has been reached is 82.714 nC.

The maximal potential energy is present at the highest point, and there is no kinetic energy due to the zero ultimate velocity at the lowest point.

<h3>What is potential energy?</h3>

The potential energy is due to the virtue of the position and the height. The unit for the potential energy is the joule.

The potential energy is mainly depending upon the height of the object.

When the egg is at the highest position, the height is maximum. Therefore, the potential energy is also maximum.

When the egg lands on the ground at the striking point only the kinetic energy exists the potential energy is zero.

According to the law of conservation of energy, total energy is defined as the sum of kinetic energy and potential energy.

Total energy = kinetic energy+potential energy

Also, the energy can not be created nor destroyed and can be transferred from one form to another form.

Hence, at the highest point potential energy is the maximum and the kinetic energy is zero. because the final velocity is zero.

To learn more about the potential energy, refer to the link;
