The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass). Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
force of friction on the cart is given as
here we also know the reaction force due to surface
so we can say reaction force is given as
now by force balance we will say
also we know that
now minimum force required to set this into motion
here we know that
So it will require 259 N minimum force to move it
Answer:
Explanation:
Apply the law of conservation of energy
from the law of conservation of the linear momentum
Therefore,
Substitute the values in the above result
B) the speed of the sphere with mass 107.0 kg is
C) the magnitude of the relative velocity with which one sphere is
D) the distance of the centre is proportional to the acceleration
Thus,
and
When the sphere make contact with eachother
Therefore,
And
The point of contact of the sphere is
