Using the impulse-momentum theorem and taking this down as positive, we will get:
FΔt = Δp
F = Δp / Δt
= m(v - v₀) / t
= 0.056kg [13m/s - (- 20m/s) / 0.00125s
= 1478.4 N when properly rounded off is the answer we are looking for in this problem.
Answer:
Some atoms do not have a proton.
Protons have about same mass as electrons.
Protons have the magnitude of charge as neutrons, but are opposite in sign.
Explanation:
Protons are the positive charge particles which are present inside the nucleus and has a mass equal to neutron.
an atom has equal number of electrons and protons hence it is not possible that atom is found in a state where is does not have any proton.
The mass of proton is equal to that of neutron but not electron. Protons are heavier than that of electrons.
Protons are the positively charged particles whereas neutrons do not have any charge present in it.
Hence the selected three options about protons are false.
Answer:
mass= 0.1993 kg
Explanation:
Using the formula c = Q / (mΔT)
Some of the scientific questions that may be answered through the experiment are:
(1) What are the physical changes that may occur in the solution or the indicator when added with acidic/basic solution?
(2) How much of the indicator is needed in order to bring about a significant physical change in the solution to identify its H+ concentration?
