Answer:

Explanation:

a) Electric Power = V X I ,  where V is potential difference  and I is current

= 12 x .18 =2.16 Watt .

b) Resistance = volt / current ( ohm's Law )

Resistance = 12/0.18 = 66.67 ohm.

A 1980-kg car is traveling with a speed of 15.5 m/s. What is the magnitude of the horizontal net force that is required to bring
Dennis_Churaev [7]

Answer: 6067.5 N

Explanation:

Work = Change in Energy. To start, all of the energy is kinetic energy, so find the total KE using: KE = 1/2(m)(v^2). Plug in 1980 kg for m and 15.5 m/s for v and get KE = 237847.5 J.

Now, plug this in for work: Work = Force * Distance; so, divide work by distance to get 6067.5 N.
