Because the car's wheels have treads slowing it down also rubbing against the rode and the theory is every force has a counter  force of equal power

A car accelerates from rest at 5 m/sec2 for 12 seconds what is the final velocity
VladimirAG [237]

 Vi =0  ( as car starts from rest )

Acceleration= a = 5m/s²

t =12sec

Vf =Vi + at

Vf= 0 + (5m/s²) (12s)

Vf=60 m/s

When a particular wire is vibrating with a frequency of 4.00 Hz, a transverse wave of wavelength 60.0 cm is produced. Determine
astraxan [27]

Answer : The speed of waves along the wire is, 1.2 m/s

Explanation :

Formula used :

\nu=\frac{c}{\lambda}

where,

\nu = frequency = 4.00Hz=4.00s^{-1}

\lambda = wavelength = 30.0cm=0.3m

c = speed of wave = ?

Now put all the given value in the above formula, we get the speed of waves along the wire.

4.00s^{-1}=\frac{c}{0.3m}

c=1.2m/s

Thus, the speed of waves along the wire is, 1.2 m/s

When the electric field strength is large, electric field lines are: a) close together.
LekaFEV [45]

Answer: a) close together

Explanation: The electric field lines also  represent the intensity of the field, in this sense  for strong electric fields it is usually draw the lines close to each other. In constrast when they are far apart the electric field is weak.
