Choice 'b' is one possible way to state
Newton's second law of motion.
The other choices are meaningless.
Answer:
higher frequency waves will have more energy
Explanation:
Answer: When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same.
Explanation:
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.
