The energy that fuels the processes inside our bodies and everything we do with our bodies comes from chemical energy stored in what we eat.

But that only raises another question: Where does the chemical energy in our food come from ?

If you follow it back far enough, eventually it ALL comes from the sun.

An electron is accelerated from rest by an electric potential difference of 437 V, and then enters a region of uniform magnetic

Lelu [443]

The radius of the electron's path is once it enters the magnetic field 3.16*10^-4 m.

The electric capacity difference, additionally called voltage, is the outside work needed to bring a rate from one region to some other area in an electric discipline. The electric powered capacity distinction is the change of potential electricity skilled by way of a test rate that has a fee of +1.

The distinction in ability among two points represents the paintings worried or the electricity released in the switch of a unit amount of power from one factor to the other.

Electric ability is the work executed in step with unit fee in bringing the fee from infinity to that factor against electrostatic pressure. In a conductor, electrons float simplest when there is a difference in electric stress at its ends. This is additionally known as the capacity distinction.

Mr. Stephenson drives his car from Dallas to Town X, a distance of 437 km. The trip takes 7.27 hours. What is the average speed

alexandr1967 [171]

Answer: Speed = 60.11 miles per hour

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

What might be an advantage to making a magnet horseshoe-shaped?

Mkey [24]

Every magnet has at least one “North” and one “South” pole where its magnetic forces leave the magnet and enter its surroundings. It is commonly thought that the magnetic forces leave one pole and enter the other pole. Therefore, The magnetic forces are concentrating the forces between those poles and making the attraction/repulsion stronger. Hope this helps! :)
