Answer:
The magnitude of the electric field in the second case will be 
of the electric field in the first case
Explanation:
The electric field at a distance 
< R from the center of the sphere is given by
the formula 
= 
where R is the radius of the sphere, and, Q is the charge uniformly distributed on the sphere.
It is given that the same charge Q is distributed uniformly throughout a sphere of radius 2R and we have to find the electric field at same distance from the center.
In the second case the electric field will be given by
= 
Therefore the magnitude of the electric field in the second case will be of the electric field in the first case.
Answer:
Conduction
Explanation:
When one object touches another heat moves through it (think of a saucepan on a hot stove). Aluminium foil is a great conductor of heat, which means it is a poor insulator when it is in direct contact with something hot.
Answer:
This is the definition of slope.
Step-by-step explanation:
The formula for slope is:
m(slope) = (y2 - y1)/(x2 - x1)
This shows the difference in y, which is rise, divided by the different in x, or run.
Answer:
The kinetic energy is 200.000 Joule (200KJoule)
Explanation:
We use the formula of kinetic energy:
Ec =1/2 x m x v^2
Ec=1/2 x 1000kg x (20m/s)^2 = 200.000Joule
200.000J/1000KJ/J=200 kJoule
