Answer: The value of x is -6.
Explanation:
To calculate the value of 'x', we need to solve each function happening inthe equation.
The equation provided to us is
To solve this, we will multiply 4x with 2 and then subtract the like terms and finally, we evaluate the value of 'x'.
Hence, the value of x will be -6.
The impulse is equal to the variation of momentum of the object:
where m is the mass object and
is the variation of velocity of the object.
The ball starts from rest so its initial velocity is zero:
. So we can rewrite the formula as
or
and since we know the impulse given to the ball (I=16 Ns) and its mass (m=2 kg), we can find the final velocity of the ball:
where m is the mass object and
The ball starts from rest so its initial velocity is zero:
or
and since we know the impulse given to the ball (I=16 Ns) and its mass (m=2 kg), we can find the final velocity of the ball:
The required value of the index of refraction of glass is 1.5.
Given data:
The speed of light in a vacuum is, .
The speed of light in a glass is, .
Light has the tendency to travel from one medium to another, then the difference between the speeds of light in various mediums is determined by a term, known as the index of refraction. The mathematical expression for the index of refraction of glass is,
n = c / v
Solving as
Thus, we can conclude that the required value of the index of refraction of glass is 1.5.
