Answer:

The magnitude of the acceleration of a proton at a distance of 1.5cm from the bead is 5.6 x10^13m/s².

The magnitude of the acceleration of a proton at a distance of 1.5cm from the bead is 9.8 x10^16m/s².

Explanation:

Newton's second law states that the total sum of the force acting on a particle in motion is equal to the mass of the particle times the acceleration due to the force. So the electric force between the bead and proton is equal to ma. That is,

Fe = kq1*q2/r² = m*a

The proton had a charge of +1.6x10^-19C and a mass of 1.67×10^-27kg

By substituting these values into the equivalent for a we have that the acceleration of the proton at a distance of 1.5cm form the bead is 5.6×10^13m/s²

The proton had a charge of -1.6x10^-19C and a mass of 9.10×10^-31kg

By substituting these values into the equivalent for a we have that the acceleration of the proton at a distance of 1.5cm form the bead is 9.8×10^16m/s²

A car interior is heated to 48 C by the sun What type of energy transfer?

Aneli [31]

Answer:

Radiation heat energy transfer

Explanation:

The type of heat transfer from the Sun is radiation heat transfer, which is the transfer of heat through electromagnetic radiation

The distance of the Sun to the Earth is several million kilometers away, with the space between being composes of vacuum and the nuclear reaction in the Sun's core generates vast amount of electromagnetic radiation that is transferred all across the universe and reaches the Earth as visible light and radiant energy at the speed of light

The radiant energy transferred from the Sun heats up the Earth, including the car's interior.

When you used the energy in our body to pull the rubber band, it was transformed into elastic potential energy. We know that ene

GuDViN [60]

Answer:

Converted to heat energy

Explanation:

Some of the elastic potential energy is transformed into heat energy. When we stretch a rubber band, it is often observed that the rubber becomes warmer after the stretch and even during the stretch.

Some energy in the band initially at rest will be converted into elastic potential energy and heat energy as it is stretched .

The heat energy is not usually accounted for since the major concern most times is the elastic energy.
In this process, heat energy becomes a waste energy.
By deducing the efficiency, we would find that this transformation is not efficient as predicted by one of the laws of thermodynamics.
