For a car moving along an unbanked turn, the frictional force provides the centripetal force required to keep the car in circular motion. Therefore, we can write:

$\mu mg = m\frac{v^2}{r}$

where the term on the left is the frictional force while the term on the right is the centripetal force, and where

$\mu=0.40$ is the coefficient of friction between the tires and the road

m is the mass of the car

$g=9.8 m/s^2$ is the acceleration of gravity

v is the speed of the car

r = 150 m is the radius of the curve

Solving for v, we find the (maximum) speed at which the car can move along the turn:

$v=\sqrt{\mu gr}=\sqrt{(0.40)(9.8)(150)}=24.3 m/s$

For speed larger than this value, the frictional force is no longer enough to keep the car along the turn.

What part of an electric circuit are the wires that carry the electric current

bezimeni [28]

Answer:

okay so, An electric circuit is a closed loop through which current can actually flow. All electric circuits must have a voltage source, for example a battery, and a conductor, which is usually a wire.

how does it flow or how does .current flow in a circuit ? When a wire is connected to battery terminals which is electrons, electrons flow from negative to positive. Electrons have a negative charge in case you didnt know. they are repelled from the negative and attracted to the positive.

if this helped please mark this as brainliest!!! :)
