Your speed when your car hits a fixed object is 60 mph.
The given parameters:
- Your initial speed, v = 60 mph
<h3>What is relative velocity?</h3>
Relative velocity tells us how fast we are traveling from a fixed point or reference point.
- When travel at 60 mph in a car, you are moving at the same rate with the car.
- If you are not wearing a seat belt, when you hit a fixed object, you will move forward at the same rate as the car's speed.
Thus, we can conclude that your speed when your car hits a fixed object is 60 mph.

Answer: DC Current
Explanation:
Battery is a source of constant potential difference and it will create a constant voltage across any conductor
due to this constant voltage difference the current in this conductor will remain constant
So here since the voltage across the conductor is constant so we can say that current in the conductor will remain constant and hence this is known as DC current.
While for variable current in direction and magnitude is to be obtained only when the conductor is connected with AC voltage source as we know that AC voltage is variable with magnitude and direction both
A battery is the power source for DC type of current. A battery is a source of constant potential difference that produces a constant current unlike in AC source where the voltage and hence the current changes its polarity continuously.Hence, the current produced by battery is direct current and not Alternating current.
Hope this helps........ Stay safe and have a Merry Christmas!!!!!! :D
Answer:
One of the most important reasons for grounding electrical currents is that it protects your appliances, your home and everyone in it from surges in electricity. If lightning was to strike or the power was to surge at your place for whatever reason, this produces dangerously high voltages of electricity in your system.

Explanation:
Height is the x-axis, and gravitational potential energy is the y-axis. As the height increases, the gravitational potential energy increases linearly.
