Answer:
speed of molecule ∝ 1/mass of molecule.
Explanation:
The velocities of the molecules depend on their masses. That's because if the molecules are large in size, their velocity is slower. Therefore their velocity is quicker when their size is small, since the molecules can move faster.
Therefore , it can be written as
speed of molecule ∝ 1/mass of molecule.
Answer:
An energy source in which we use to power most powerplants and reactors.
Explanation:
So we want to know what will happen to the needle of a compass that is held upright and pointing left in front of the solenoid if the current in the solenoid is reversed. If the current is reversed in the solenoid then the direction of the magnetic field of the solenoid is also reversed. So the needle that was pointing left will now point right after the direction of the current is changed.
