Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave.
To understand this it is good to think of a rope being held still by person B and being moved up and down by person A. The direction of propagation is from person A to B, so you will see the waves move along this way. But the displacement will be up and down.
Can travel in solids, but not in liquids and gas.
eg. Electromagnetic radiation
Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.
A good example for this is a slinky being pushed along the table, the propagation will be along the table and so will the displacement of all the 'rings'.
Can travel through all states of matter.
eg. Sound waves
The current values in and out of the battery is going to be equal to the sum of the currents going through the light bulbs. In a parallel circuit, the current is divided as it enters different branches and light bulbs. However, the amount of current leaving the battery is always going to be the same as the amount of current entering the battery. Therefore, while current divides in a parallel circuit, the total amount of current always remains the same.
Ohm's law:
V = I * R, so R = V/I = 9/1.5 = 6 Ohm

Centripetal acceleration is the acceleration of an object acted upon a force that pulls it toward the center of origin. For constant speed, there is no acceleration, since acceleration is defined as the difference of velocities at an elapsed time. Hence, if speed doubles, then the centripetal acceleration would increase as well.
