Answer:

A.C → Alternating current.

D.C → Direct current

Explanation:

A.C is an abbreviation for Alternating current.

Alternating current is a type of current that flows sinusoidally or current that changes direction with time.

D.C is an abbreviation for Direct current.

This type of current flows only in one direction, i.e it doesn't change direction with time.

A rectifier can be used to convert A.C to D.C, allowing it to flow in one direction.

HELP PLS MARKING BRANLIST 100 pts TAKING TEST RN
AlladinOne [14]

Answer:

15 m/s^2 The first thing to calculate is the difference between the final and initial velocities. So 180 m/s - 120 m/s = 60 m/s So the plane changed velocity by a total of 60 m/s. Now divide that change in velocity by the amount of time taken to cause that change in velocity, giving 60 m/s / 4.0 s = 15.0 m/s^2 Since you only have 2 significaant figures, round the result to 2 significant figures giving 15 m/s^2

Lorico [155]
The plant will not grow. In fact it could have all the nutrients and all the water it needs, but without a sufficient amount of light, it could die because its leaves are meant for a certain minimum amount of light.
