Answer: 46.5 m/s
Explanation:
Momentum = mass(m) × velocity (v)
momentum of car = momentum of truck
1210 × v = 2250 × 25
v = 46.5 m/s
Answer:
1. They should not trust this study. 2. Pseudoscience.
Explanation:
Because they drank the water and after 24 hours, they said that it was gone. Head aches go away sooner than that. Another reason is that some people could have lied about having a headache just so they could have the water or their headache could have gone away before they drank the water.
It increases with the motion of particles within a substance
I just took the test
The wire needs to be sauderwired to be connected back into place to get energy into column so it came function properly again!
The correct answer is
C. Light can pass through Object B faster than it can pass through Object A.
In fact, the index of refraction of a material is defined as:

where c is the speed of light in vacuum and v is the speed of light in the material. Rearranging the equation, we can write the speed of light in the material as:

So we that, the smaller the refractive index n, the greater the speed of light in the material, v. In this problem, object B has lower refractive index than object A, so light travels faster in object B.
