56 J of work was done to increase the kinetic energy of a 1.90 kg mass. If the object’s initial velocity was zero, what is its s
const2013 [10]

Answer:

7.68 m/s

Explanation:

Ek = 56 J

m = 1.90 kg

u = 0

v = ?

Ek = 0.5m(v - u)²

56 = 0.5×1.90×(v -0)²

56 = 0.5×1.90v²

56 = 0.95v²

v² = 56/0.95 = 58.95

v =√58.95

v = 7.68 m/s

A 10.0-cm-long solenoid of diameter 0.400 cm is wound uniformly with 800 turns. A second coil with 50 turns is wound around the
levacccp [35]

Answer:

M = 6.32 x 10⁻⁶ H

Explanation:

given,

Length of solenoid = 10 cm = 0.1 m

diameter = 0.40 cm

radius = 0.2 cm = 0.002

number of turns, N₁ = 800

                            N₂ = 50

mutual inductance will be equal to  

     M = \dfrac{\mu_0N_1N_2A}{l}

     M = \dfrac{4\pi \times 10^{-7}\times 800\times 50 \times \pi \times (0.002)^2}{0.01}

           M = 6.32 x 10⁻⁶ H

hence, mutual inductance of the combination of two coil is equal to  M = 6.32 x 10⁻⁶ H
