Answer:
Option A, Boyle's law
Explanation:
The complete question is
Pressure and volume changes at a constant temperature can be calculated using
a. Boyle's law. c. Kelvin's law.
b. Charles's law. d. Dalton's law.
Solution
In Boyle’s law, the gas is assumed to be ideal gas and at constant temperature. With these two conditions fixed, Boyle’s established that volume of gas varies inversely with the absolute pressure.
The basic mathematical representation of this phenomenon is as follows -
OR
Where P is the pressure of ideal gas, V is the volume and k is the constant of proportionality.
Hence, option A is correct
in a hypotonic solution like distilled water, a red blood cell would burst, because inside the cell has a higher solute concentration than outside.
In a hypertonic solution, there is a higher solute concentration on the outside of the cell than on the inside, causing the cell to shrivel.

Answer:20 mph
Explanation:
Given
distance between college to Tyrone=20 miles
Given professor drives with a velocity of 60 mph
he returns to college after reaching tyrone and then again drive to tyrone.
so his net displacement is 20 miles
time taken to cover 20 miles is 
hr
average velocity
Explanation:
It is given that,
Mass of the car, m = 1000 kg
Speed of the car, v = 100 km/h = 27.77 m/s
The coefficient of kinetic friction of the tires, 
Let f is the net force acting on the body due to frictional force, such that,
We know that the acceleration of the car in calculus is given by :
, x is the stopping distance
On solving the above equation, we get, x = 78.69 meters
So, the stopping distance for the car is 78.69 meters. Hence, this is the required solution.
