Heat can be transferred from one place to another by three methods:
conduction in solids,
convection of fluids (liquids or gases),
radiation through anything that will allow radiation to pass.
bonded pairs of electrons, lone pairs of electrons.
Answer:
Explanation:
Given
same charge on both masses
potential Energy due to Magnetic Field =Kinetic Energy of Particle
and we know
Force due to magnetic field will Provide centripetal Force
and B is equal for both particles
thus 
Answer:
1703.24J
Explanation:
Given parameters:
Mass of brick = 7.9kg
Height of building = 22m
Unknown:
Potential energy of the brick = ?
Solution:
The potential energy of a body is the energy at rest of the body. Mathematically;
P.E = mgh
m is the mass of the brick
g is the acceleration due to gravity
h is the height of the building
Insert the given parameters and solve;
P.E = 7.9 x 9.8 x 22 = 1703.24J
