Answer:

C. accelerates.

D. changes speed but not direction.

Explanation:

• When the body accelerates, the net force increases, when changes speed, acceleration changes and force as well.

{ \rm{force = mass \times acceleration}}

» So, the force is determined by acceleration.

{ \rm{force = mass \times ( \frac{ \delta \: speed}{time}) }} \\

» Also force is determined by change in speed

Calculate the total resistance in a series circuit made up of resistances of 3Ω, 4Ω, and 5Ω.
-BARSIC- [3]
The total resistance in a series circuit is equal to the sum of all resistors (R total = ΣRi).

R total = R1 + R2 + R3 = (3 + 4 + 5) Ω = 12 Ω

A car travels 82 meters do North and 14 seconds the car turns around and travels 44 m due south in four seconds what is the magn
Yakvenalex [24]

Answer:

2.11 m/s

Explanation:

Take north to be positive and south to be negative.

Average velocity = displacement / time

v = (82 m + -44 m) / (14 s + 4 s)

v = 2.11 m/s

The velocity is positive, so it is 2.11 m/s north.  The magnitude of the velocity is 2.11 m/s.
