Answer:
4.56 seconds
63.25 m
Explanation:
t = Time taken for the car to stop
u = Initial velocity = 60 km/h = 100 km/h = 100000/3600 = 27.78 m/s
v = Final velocity = 0
s = Displacement
a = Acceleration = -6.1 m/s²
Time taken by the car to stop

Time taken by the car to stop is 4.56 seconds

The total stopping distance would be 63.25 m
The solutions would be :
1. C
2. B
3. A
4. C
5. D.
To make something electrical you need electricity and the wires will turn a magnet into an electromagnet.

We are given a series circuit with two light bulbs. In this case, the light bulbs act as resistors in series and the total resistance is:

That is the sum of all the resistances in series in the circuit. To determine the voltage we can use Ohm's law:

Where "R" is the total resistance and "I" is the current in the circuit. Replacing we get:
