Answer:
Sound quality depends on a lot of factors, and it is impossible to definitively state that either analog or digital is fundamentally better. These days, many records are made using playback of a digital file, so vinyl preference cannot be attributed solely to the differences in the way the sound wave is reproduced.

Answer:
Explanation:
Here we have an inelastic collision problem. We can use the momentum (p = mv) conservation law in each component of the displacement.
So,
<u>X-component:</u>
(1)
Now,
- v(i1x) is 0, because the first car just moving in y-direction
- v(i2x) is 164 km/h
- v(f1x)=v(f2x), because both cars stick together after the collision, so they have the same x-component velocity.
Then, using this information we can rewrite the equation (1).
<u>Y-component:</u>
(2)
We can do the same but with the next conditions:
- v(i1y) is 239.44 km/h
- v(i2y) is 0, because the second car just moving at the x-direction
- v(f1y)=v(f2y), because both cars stick together after the collision, so they have the same y-component velocity.
Then, using this information we can rewrite the equation (2).
Now, as we have both components of the final velocity, we can find the angle East of North. Using trigonometric functions, we have:
I hope it helps you!
1. Applying more force and energy, speeding up
2. Releasing potential and kinetic energy by going down a slope, speeding up
3. Applying less force to slow down and let friction overcome the bicyclist
I say it is false that is the correct answer
The answer is d, gravity is the only force acting on the object
