If you are over-driving your headlights and you see an object ahead, you will_____. be given the right-of-way from other vehicle

SashulF [63]

Answer: not be able to stop in time to miss the object

Explanation:

The phrase "Over-driving your headlights" means that a person is driving at such a speed that the vehicle's stopping distance is greater than the maximum viewable distance with the headlights on.

When this occurs, it will be impossible for the vehicle to stop moving in time to avoid an object viewed by the driver in the range of his headlights.

This is a <u>dangerous driving practice</u> and can be avoided by driving at <u>reduced speeds</u>.

The starter motor of a car engine draws an electric current of 20.0 A from the battery. The copper wire to the motor is 5.90 mm

insens350 [35]

Answer:

q = 13 C

Explanation:

Given that,

Electric current, I = 20 A

The starter motor runs for 0.65 s before the car engine starts up.

We need to find how much of electric charge passes through the starter motor. Let it is q.

Electric current = electric charge/time

$I=\dfrac{q}{t}\\\\q=It\\\\q=20\ A\times 0.65\ s\\\\q=13\ C$

So, 13 C of electric charge passes through the starter motor.

A roller coaster car is going over the top of a 18-mm-radius circular rise. At the top of the hill, the passengers "feel light,"

Andre45 [30]

Answer:

0.29713 m/s

Explanation:

m = Mass of person

g = Acceleration due to gravity = 9.81 m/s²

v = Velocity

r = Radius = 18 mm

By balancing the forces in the system we have

$mg-N=\dfrac{mv^2}{r}\\\Rightarrow mg-\dfrac{mg}{2}=\dfrac{mv^2}{r}\\\Rightarrow v=\sqrt{r(g-\dfrac{g}{2})}\\\Rightarrow v=\sqrt{0.018\times (9.81-\dfrac{9.81}{2})}\\\Rightarrow v=0.29713\ m/s$

The velocity of the coaster is 0.29713 m/s
