B. Neutrons or Protons Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium. (Actually, a few neutrons have to be added as well to make the new nucleus stable, but the end result is still helium.)
Answer:
It is due to the large impulse is imparted on the flour.
Explanation:
A ball is moving faster.
When a ball is moving faster strikes to the flour, the change in momentum is large and thus the impulse imparted on the flour is large.
Impulse = change in momentum
So, as the flour experiences large impulse and large momentum so that the flour spreads out.
If the change in momentum is large so the flour spreads out is more.
Answer:
I mean its probably a magnet so look at the fraction of the initial Kinetic Energy of magnets
Explanation:
Answer:
Option (b) is correct.
Explanation:
The amount of heat required to raise the temperature of substance of mass 1 kg by 1 degree C, is called specific heat of the substance.
The formula of the specific heat is
H = m c (T' - T)
where, m is the mass, c is the specific heat and T' - T is the change in temperature.
So, to know the rise in temperature, by adding the known amount of heat, the specific heat is required.
So, option (b) is correct.
