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:
The value is
Explanation:
From the question we are told that
The distance of the target from the riffle is
The height at which the bullet hit the target is
Considering the vertical motion
Generally from kinematic equations we have that
At the initial stage the velocity is zero i.e
=>
=>
Generally the velocity of the bullet when it leaves the riffle is mathematically represented as
=>
=>
