The tail consists of gas and dust that can extend hundreds of millions of kilometers away from the coma. Most comets actually have 2 tails: a plasma tail made of ionizedgas, and a dust tail made of small solidparticles. Comet tails point away from the Sun.
Answer:
Explanation:
Magnetic field due to a long wire
B = ( μ₀ / 4π ) x 2 I / r ( I is current through the wire )
= (μ₀ Q t ) / ( 2 π r ) [ I = Q t ]
b ) Magnetic field will change through the length of the square shaped loop . So we shall have to take the help of integration to calculate the flux through the loop.
Flux Φ = ∫ B dA
=∫ ( μ₀ / 4π ) x 2 I / r dA
10⁻⁷ x 2 I ∫ a dr/r
2 x 10⁻⁷ x Qt x a [ ln (2.9+1.2) / 1.2 ]
4.6 x 10⁻⁷ x 2.9 x 10⁻² t ln 4.1 / 1.2
16.4 x 10⁻⁹ t
Φ( t ) = 16.4 x 10⁻⁹ t
Induced emf = dΦ( t ) / dt = 16.4 x 10⁻⁹ v
current
16.4 x 10⁻⁹ / 2.5
= 6.56 x 10⁻⁹
Answer:
3751.80514 radians
Explanation:
= Final angular velocity
= Initial angular velocity
= Angular acceleration
= Angle of rotation
t = Time taken
The angular displacement would be 2932.8 rad
The angular displacement would be 4570.8 rad
Actual value of the angular displacement is 3751.80514 radians
