When sulphur burns it turns to sulphur dioxide
Explanation:
It is given that,
Mass of the bullet, m₁ = 0.093 kg
Initial speed of bullet, u₁ = 100 m/s
Mass of block, m₂ = 2.5 kg
Initial speed of block, u₂ = 0
We need to find the speed of the block after the bullet embeds itself in the block. Let it is given by V. On applying the conservation of linear momentum as :
V = 3.58 m/s
So, the speed of the bullet is 3.58 m/s. Hence, this is the required solution.

Answer: E. None of the above
Explanation: The energy of a photon is given by the formula below.
E=hf or E = hc/λ
E = energy, h = planck constant, c= speed of light and
λ= wavelength.
From E=hf we can see that energy is directly proportional to frequency since h is a constant, this implies that as we move up the visible light spectrum, red light has the least frequency this accounting for the lowest energy while violet has the largest energy accounting for a very high energy.
Blue light is higher in the spectrum than red light.
This implies that blue light has more energy than red.
Visible light is part of the electromagnetic spectrum which implies that they all travel with the same speed of a constant value ( speed of light = 3* 10^8 m/s).
Thus in conclusion, blue light has more energy that red light but they both travel with the same speed.
This point nullifies the options thus making none of it correct.
Material composing the body,
temperature of the body and the length of the body affects the electrical
resistance of a body. Bodies directly surrounding the body will not affect the
electrical resistance of the body. The answer is letter D.
