Answer:
x = 1, y = 1 and z = 0
Explanation:
Given equation;

Boyle's law states that at constant temperature, the volume of a fixed mass of gas is inversely proportional to its pressure.
Mathematically the law is written as;

From the given equation, the values of x, y and z that will match this law is calculated as follows;

Answer:
F=4040.81 N
Explanation:
Given that
Time ,t= 2.45 ms
Mass ,m= 0.055 kg
v= 1.8 x 10² m/s = 180 m/s
We know that rate of change in the linear momentum is known as force.
Momentum P = m v

Therefore force F


F=4040.81 N
Therefore force on the ball will be 4040.81 N
Speed (v) = wavelength (λ) x frequency (f)
If speed is constant and frequency is reduced by factor of 3, you will need to increase wavelength by the same factor so that your changes reduce out.
Answer is A.
Answer:

Explanation:
The electric potential can be found by using the following formula

Applying this formula to each charge gives the total potential.

Since the potential is a scalar quantity, it is safe to sum all the potentials straightforward. And since they all placed on the corners of a square, +3 and -3 μC charges cancel out each other.
