Would be a. since KE = 1/2 m*v^2
Answer:
A
Explanation:
Molecules is made up from and atom is made up with three tiny elements: protons, neutrons, and electron.
The distance it takes 4 hours to travel 128 miles is 512 miles
HOW TO CALCULATE DISTANCE:
- The distance can be calculated by multiplying the velocity by time taken:
- Distance (miles) = velocity (miles/hr) × time (hr)
- According to this question, it takes 4.0 hours to travel 128.0 miles/hr. The distance can be calculated as follows:
Distance = 128 × 4
Distance = 512 miles
- Therefore, the distance it takes 4 hours to travel 128 miles is 512 miles.

Snell's law is defined as “The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media”.
The ozone layer absorbs UV
(ultraviolet) radiation. The answer is letter C. the ozone layer is able to
oxidize the electros and photons in the UV rays so that the light that can pass
through can be not harmful to humans.
