Explanation:
Given that,
Number of turns in the coil, N = 100
Area of the coil, A = 100 cm² = 0.01 m²
It is placed at an angle of 70°.
Magnetic field, B = 0.1 Wb/m²
We need to find the magnetic flux through the coil and the emf is induced in the coil after 10⁻³ s.
Magnetic flux is given by :
So, the magnetic flux through the coil is 0.1 Wb.
Emf induced in the coil is :
So, 34V of emf is induced in the coil.
Answer:
Electromagnetic induction is a phenomenon in which a changing magnetic field across a loop of wire results in the generation of an induced emf. When there is relative motion between a magnet and the coil, magnetic flux changes and hence an electromotive force is generated in the coil.
Answer:
Mass, m = 1561.23kg
Explanation:
Given the following data;
Weight = 15300N
We know that acceleration due to gravity is equal to 9.8m/s²
To find mass;
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;
Where;
- m represents the mass of an object measured in kilograms.
- g is the acceleration due to gravity measured in meters per seconds square.
Substituting into the equation, we have;
<em>Mass, m = 1561.23 Kg</em>
<em>Therefore, the mass of the car is 1561.23 kilograms.</em>
