Two tiny conducting spheres are identical and carry charges of -18.4 µC and +53.0 µC. They are separated by a distance of 2.73 cm. (a) What is the magnitude of the force that each sphere experiences, and is the force attractive or repulsive?

-11776.36 N

This force is attractive since both charges are of opposite sign

Explanation:

Given that

Distance between the spheres = 2.73 cm =0.0273 m

where K is Coulomb's constant =

According to coulombs law we know that force between two charges is given by

This force is attractive since both charges are of opposite sign

1.The Sun transforms nuclear energy into heat and light energy.

2.Our bodies convert chemical energy in our food into mechanical energy for us to move.

3.An electric fan transforms electrical energy into kinetic energy.

Explanation:

1.The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun's surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).
