Answer:
C. 1.5 W/m²
Explanation:
= Unpolarized light = 4 W/m²
= Angle with which the polarizer is turned
The polarization of light is given by

The intensity of light after passing through the first polarizer is 1.5 W/m²
Answer:
B)
D)
Explanation:
Carnot cycle ;
This is the ideal cycle for all type of heat engine.All the process in the Carnot cycle is reversible processes ( those process does not leave any effect on the system as well as surrounding when the process is reversed is known as reversible process).It have four process in which two process is constant temperature and other two is isentropic or we can say that reversible adiabatic.
In the two process(constant temperature) only heat interaction take places and other two process(adiabatic) only work interaction take places.
So the option B and D is incorrect for Carnot cycle.
Answer:
93328 kg
Explanation:
= Density of mud = 1900 kg/m³
Volume of the cuboid is given by

Volume is also given by

The length of the cuboid is 0.89312 m
For the small volume

Mass is given by

The mass of the mud is 93328 kg
Answer:
Explanation:
There is no acceleration in vertical direction
Fn = mg + Fp sin 35
Frictional force = 99.7 N
Net force in forward direction = Fp cos 35 - 99.7
= 168 cos 35 - 99.7
= 137.61-99.7
= 37.91 N
net acceleration of chair = net force / mass
= 37.91 / 50
= .7582 m / s² .
