Answer:
n = 1.76
Explanation:
According to the rule of ( n1 sin theta1 = n2 sin theta2 )
we know both angles so we insert them to the law and apply n1 = 1
so 1/2 = n2 sin 62 and we get the final answer
Answer:
Object C has the most potential energy.
Between A and B, we do not know which has more potential energy.
Explanation:
We know the object with the most potential energy and this is the object at C.
Potential energy is the energy due to the position of a body above the ground surface.
The higher a body is above ground, the more its potential energy.
Potential energy = mass x acceleration due to gravity x height
So;
Object C has the most potential energy.
Between A and B, we do not know which has more potential energy.
This is because, the height and mass of the objects are not quantified using numbers.
Potential energy is a function of mass and height and acceleration due to gravity but acceleration due gravity is a constant.
Answer:
Explanation:
Let the electric field strength is E and the charge is q. The force experienced by the charge due to the presence of electric field is
F = q x E
The direction of force is same as that of the electric field strength if the charge is positive in nature and if the charge is negative in nature the direction of force is opposite to the direction of electric field.
Answer: C
use formula F=ma : Force = mass(acceleration)
F = 1000(0.5)
F = 500N
