Answer:
Efficiency
Explanation:
- The amount of mechanical work an engine can do per unit of heat energy it uses is called its efficiency.
- It is also defined as the output divided by the total electrical power consumed.
- In terms of heat, efficiency of engine is given by :
are output heat and input heat respectively.
Hence, the correct option is (d) "efficiency"
Answer:
3947.6 N
Explanation:
Centripetal Force: This is the force that tend to moves a body towards the center of a circle during circular motion.
The formula for centripetal force is
F = mω²r ........................ Equation 1
Where F = Centripetal force, ω = angular velocity, r = radius.
Where π = 3.1415
Given: m = 4 kg, ω = 0.5 rev/s = (0.5×2π) rad/s = 3.1415 rad/s, r = 100 m.
Substitute into equation 1
F = 4(3.1415)²(100)
F = 3947.6 N
Hence the centripetal force on the turbine blade = 3947.6 N
Answer:
A group of atoms where the magnetic fields of the atoms point in the same direction is a magnetic domain.
Explanation:
- In every magnet's magnetic field there is a region where the magnetization is in the same direction. This region is known as magnetic domain.
- In the magnetic domain the atoms always points in the same magnetic filed direction.
- All the atom's magnetic field align in one particular direction.
- This region where atoms align is called as domains.
