Two, large, parallel, metal plates are connected to a DC power supply. The plates are squares. The plate connected to ground is at x = 0 and sits in the y-z plane. The x-axis runs perpendicular to the plates. The other plate is connected to the positive terminal of the power supply. z y 5 pts For the parallel plates mentioned in the previous question, what is the direction of the electric field? a) negative z b) positive y c) negative y d) negative x e) positive x f) positive z

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
