The correct option is D.
The Quantum theory states that both light and matter are made up of small particles that possess wavelike and particle like properties. This is described as the dual nature of light and matter. Light is made up of photons while matter is made up of electron, proton and neutron. The two can behave as both waves and particles.

Answer:
The mass of the bullet is 15 g.
(b) is correct option.
Explanation:
Given that,
Momentum = 2.8 kg m/s
Speed = 187 m/s
We need to calculate the mass of the bullet
Using formula of momentum
Where, P = momentum
v = speed
Put the value into the formula
Hence, The mass of the bullet is 15 g.
