Answer:
a
The mass is
b
The velocity is
Explanation:
From the question we are told that
The speed of the protons is
The mass of the protons is
The speed of the rebounding protons are
The negative sign shows that it is moving in the opposite direction
Now according to the law of energy conservation mass of one nucleus of the unknown element. is mathematically represented as
Where is the mass of a single proton
So substituting values
The mass of on proton is
So
Now according to the law of linear momentum conservation the speed of the unknown nucleus immediately after such a collision is mathematically evaluated as
Now because before collision the the nucleus was at rest
So
=>
Recall that
So
=>
substituting values
The velocity of light in glycerol is 2.04 × 10⁸ m/s.
To find the answer, we need to know about the expression of velocity of light in any medium.
<h3>What's the expression of the speed of light in any medium?</h3>
- Mathematically, the speed of light in any medium= C/n
- C = speed of light in vaccum, n = refractive index of the medium
<h3>What's the speed of light in glycerol having refractive index of 1.47?</h3>
Speed of light in glycerol= 3×10⁸/1.47 = 2.04 × 10⁸ m/s
Thus, we can conclude that the velocity of light in glycerol is 2.04 × 10⁸ m/s.

Answer:
physical measurement comprises the measurement of objects, things, etc. and is concerned with the measurement of height, weight, length, size, volume etc.
Answer:
Explanation:
<u>Average Speed</u>
The speed of an object is the rate of change of its distance. When an object travels at different speeds over time, the average speed is usually calculated to represent the whole travel.
The average speed is the total distance (d) traveled by the object divided by the elapsed time to cover that distance (t):
The airplane covers a distance of d=1200 m in t=90 s. The average speed is:
