You actually sweating if the cooling part. you sweat so you can cool down.
When water freezes, it's volume INcreases, which naturally results in a DEcrease in it's density. That's why cubes and bergs float.
I'm pretty sure that water is the only known substance that behaves this way. Which is lucky for us, because if it didn't, then life on Earth would be impossible. Oceans and lakes would freeze from the bottom up. Once! And then they would never thaw, because the sun could never cut through the layer of warm water on top, to melt the ice below.
Answer:
The kinetic energy of an electron is
Explanation:
Given that,
Distance = 0.1 nm
We need to calculate the momentum
Using uncertainty principle
Where, = change in momentum
= change in position
Put the value into the formula
We need to calculate the kinetic energy for an electron
Where, P = momentum
m = mass of electron
Put the value into the formula
Hence, The kinetic energy of an electron is
Force on a moving charge inside magnetic field is given by
So as per right hand rule if we put our fingers of right hand along the velocity of charge and then curl it towards the magnetic field direction then thumb will show the direction of force on moving charge.
Above rule is known as right hand rule.
If we use the same for the given condition then velocity is given out of the plane and magnetic field is downwards then as per right hand rule direction of force on the moving charge will be "Towards Right"
