Decreasing pressure on a gas will cause its volume to increase, as it isn't being forced into a smaller space. Increasing temperature causes the atoms in the gas to contain more energy, making them move around more. This too increases the volume.
So basically both would increase the volume of the gas. Hope this helps
Because they behave just like all the electromagnetic waves of the spectrum. Same equations, just shorter wavelengths and more energy.
Hope you get it :)
1. The current can be calculated using the equation :
Force = current × length of wire × magnetic field strength
Plug in all the values
1.20 = current × 0.80 × 0.60
Simplify
1.20 = current × 0.48
Isolate for current
current = 2.5 Amps
2. electron moves east
magnetic field is downwards
the velocity, field and force all all perpendicular to each other. You can use the straight fingered left hand rule to determine the direction of the force.
Point your index finger to the right side (east), point your middle finger down towards the ground while you keep your index finger in place. You're left with your thumb pointing towards you, which is the south direction.
The direction of the force is south
