Answer: C. Some of uranium's mass is converted into energy, so the smaller atoms have less mass.
Explanation:
From Einstein's mass-energy relation:
E = mc²
Mass and energy are equivalent. Mass can be converted into energy and energy into mass.
When Uranium atoms under go nuclear fission, smaller atoms are formed and huge amount of energy is released. This energy comes from the mass difference of the uranium nuclei and new nuclei formed. This mass converted into energy according to Einstein's equation.
I think the answer is D but i could be wrong
Answer:
Radiation , Conduction and Convection
Explanation:
Those are the ways heat is transferred
Answer:
Explanation:
Given:
- mass of the one ion,
- mass of another ion,
- velocity of projection into the magnetic field,
- charge on each ion,
- magnetic field,
We have, force on a charged particle due to the perpendicular magnetic field:
............................(1)
Force on mass moving in a circular trajectory
...............................(2)
where "r" is the radius of trajectory.
from eq. (1) & (2)
putting the values for the condition 1:
putting the values for the condition 2:
∵The charges have covered a semicircular path from the point of entrance,
∴ their difference in the radius will give their distance from each other.
Answer:
Coefficient of kinetic friction = 0.38 (Approx.)
Explanation:
Given:
Applied force = 45 N
Mass of wooden crate = 12 kg
Find:
Coefficient of kinetic friction
Computation:
Coefficient of kinetic friction = Applied force / (Mass)(Acceleration due to gravity)
Coefficient of kinetic friction = 45 / (12)(9.8)
Coefficient of kinetic friction = 45 / 117.6
Coefficient of kinetic friction = 0.3826
Coefficient of kinetic friction = 0.38 (Approx.)
