When storm clouds produce lightning and thunder, energy changes to energy and energy.
balandron [24]
When storm clouds produce lightening and thunder, then, potential energy changes into kinectic energy.

The clouds become negatively charged,and the ground is positively charged during a storm. So there creates a potential difference between the charged clouds and the ground. And when this becomes huge so much that it over comes the electrical insulation cover of air, the electrons jump to the ground.i.e. the potential energy changes into kinetic energy.

zmey [24]

Answer:

The divergence on the sensor shows the magnitude of the charges

Explanation:

This will increase as length increases since it is said to be proportional to the length. note that test charge is always positive and charge on the grid is positive as indicated (1 nC)

A 296-kg motorcycle is accelerating up along a ramp that is inclined 26.2° above the horizontal. The propulsion force pushing th
Alexeev081 [22]

Answer:

The magnitude of the motorcycle's acceleration is 5.20 m/s².

Explanation:

Given that,

Mass of motorcycle = 296 kg

Angle = 26.2°

Force on motorcycle= 3106 N

Force = 286 N

We need to calculate the magnitude of the motorcycle's acceleration

The net force acting on the motorcycle

Using newton's second law

ma=F_{p}-F_{air}-F_{g}

ma=F_{p}-F_{air}-mg\sin\theta

Put the value into the formula

296a=3106-286-296\times9.8\times\sin26.2

a=\dfrac{3106-286-296\times9.8\times\sin26.2}{296}

a=5.20\ m/s^2

Hence, The magnitude of the motorcycle's acceleration is 5.20 m/s².
