In collision of the steel ball and the steel plate, the collision is an inelastic collision and there is loss in the kinetic energy.

<h3>What are collisions?</h3>

Collisions occur when two objects that are moving in the same directions or in different direction meet each other and collide.

There are two types of collisions:

  • elastic collision - the kinetic energy is conserved
  • inelastic collision - there is a loss in kinetic energy

In the collision of the steel ball and the steel plate, there is loss in the kinetic energy of the steel ball which is converted to sound energy.

In conclusion, the collision of the steel and steel plate is an inelastic collision.

pogonyaev

Answer:

a = 5.7 \times 10^{-5} m

Explanation:

As we know that position of first minimum on the either side of central maximum is given as

a sin\theta = \lambda

\theta =sin^{-1} \frac{\lambda}{a}

so the width of the central maximum is given as

W = L (2\theta)

so we have

15.20 \times 10^{-3} = 0.68 \times 2(sin^{-1} \frac{\lambda}{a})

so we have

0.011 = sin^{-1} \frac{\lambda}{a}

0.011 = \frac{638 nm}{a}

a = 5.7 \times 10^{-5} m

fiasKO [112]

Answer:

636.619772368 A

Explanation:

\tau = Torque = 1\times 10^{-3}\ N/m

B = Magnetic field of Earth = 5\times 10^{-5}\ T

A = Area

d = Diameter = 20 cm

Current is given by

I=\dfrac{\tau}{BA}\\\Rightarrow I=\dfrac{1\times 10^{-3}}{5\times 10^{-5}\times \dfrac{\pi}{4}\times 0.2^2}\\\Rightarrow I=636.619772368\ A

The current is 636.619772368 A
