The correct answer is letter C, regular reflection.
<span>An image seen in a smooth dinner plate is an example of a
regular reflection. This phenomenon only occurs in smooth and polished surfaces.
During this stage light occurs at a certain angle and is reflected back at the
same angle producing reflections in a way like a mirror does this commonly.</span>
In an Inelastic Collision , the momentum of system is conserved .
In the question ,
it is asked about what happens in inelastic collision .
The Inelastic collision is defined as a collision in which there is a loss of kinetic energy. While the momentum of system is conserved in an inelastic collision, kinetic energy is not.
That's because some kinetic energy gets transferred to something else like ⇒ thermal energy, sound energy, or material deformation .
For Example : Let the two similar trolleys are traveling towards each other and if they collide,
but the trolleys are equipped with magnetic couplers they join together in the collision and behave like a one connected mass. This collision is perfectly inelastic .
Therefore , the details about Inelastic Collision is explained above .

Answer:
a) 378Ns
b) 477.27N
Explanation:
Impulse is the defined as the product of the applied force and time taken. This is expressed according to the formula
I = Ft = m(v-u)
m is the mass = 70kg
v is the final velocity = 5.4m/s
u is the initial velocity = 0m/s
Get the impulse
I = m(v-u)
I = 70(5.4-0)
I = 70(5.4)
I = 378Ns
b) Average total force is expressed as
F = ma (Newton's second law)
F = m(v-u)/t
F = 378/0.792
F = 477.27N
Hence the average total force experienced by a 70.0-kg passenger in the car during the time the car accelerates is 477.27N

Answer:
Explanation:
It is given that,
Mass of the loop, m = 10 g = 0.01 kg
Resistance of the loop, R = 0.02 ohms
Dimension of square loop, 7 cm × 7 cm
Area of the loop,
At time t = 0 s, the magnetic field increases from 0 to 1 T in 0.01 s
(a) Due to change in magnetic field, an emf is induced in the loop. Using the formula for induced emf as :
Now using Ohm's law to find the induced current in the loop. It is given by :
I =24.5 A
(b) A magnetic force acting on the loop is given by :
F = 0.8575
Since,
v = 0.8575 m/s
Hence, this is the require solution.
