Answer:
The question is incomplete. I will assume you intend to find the total momentum of the two carts during collision. Therefore, we can use the conservation of momentum principle to get the total momentum at a certain instant before collision.
Explanation:
The conservation of momentum principle states that the initial net momentum of two bodies before collision is equal to the final net momentum after collision.
In this case, let's denote the rolling cart as <em>'a'</em> and the stationary cart as <em>'b'</em>.
Therefore, the total momentum before collision is 11.02 Kg.m/s.
Answer:
c) billions
Explanation:
there are more than 0 stars, because our sun is a star
and there are more than one because the milky way has a lot of suns
there aren't infinite because the milky way is finite it has some volume and even you made the smallest star possible you wouldn't have infinite stars
so the only option is billions
Answer:
35.16 degrees
Explanation:
Knowing that the index of refraction of the guide is 1.33, calculate the resulting angle of refraction for a ray of light that falls on a pool with an angle of incidence of 50º
Refractive index, n = 1.33
The angle of incidence, i = 50°
We need to find the angle of refraction. let it is r. It can be calculated using Snells law as follows:
So, the angle of refraction is 35.16 degrees.
Answer:
a. 8p
Explanation:
We are given that
Radius of hollow sphere , R1=R
Density of hollow sphere=
After compress
Radius of hollow sphere, R2=R/2
We have to find density of the compressed sphere.
We know that
Therefore,
Volume of sphere=
Using the formula
Hence, the density of the compressed sphere=
Option a is correct.
