Answer:
D) This is the correct answer
Explanation:
In this exercise the two ball loads are suspended by a thread.
To answer this exercise, let us remember that charges of the same sign repel and charges of a different sign attract.
Therefore, for the system to maintain equilibrium, the two charges must be of the same sign.
When examining the different proposals
A) in this case, as a sphere has no charge, there is no electric force and the induced charge is of the opposite sign, so the spheres attract each other
B) in this case there is an electric force, but being of a different sign, the force is attractive so the system is not in equilibrium
C) as the charges are of different magnitude the system does not have equal angles
D) This is the correct answer, since the charges have the same magnitude and are of the same sign, so the force is repulsive and is counteracted by the weight component
F_e = W sin θ
Answer:
the watt is the unit of power or radiant flax
Answer:
I think the answer is B, I am not for sure
Answer:
The acceleration and the distance are 25200 mi/h² and 0.1008 mi.
Explanation:
Given that,
Initial speed = 71 mi/h
Final speed = 50 mi/h
Time = 3.0 s
(a). We need to calculate the acceleration
Using equation of motion
Put the value in the equation
Negative sign shows the deceleration.
(b). We need to calculate the distance
Using equation of motion
Hence, The acceleration and the distance are 25200 mi/h² and 0.1008 mi.
