Answer:
An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current in the conductor. In the circuits using metallic wires, electrons constitute a flow of charges.
Answer:
the answer is B. it's too easy
Answer:
clockwise torque is due to weight of the person + weight of the ladder
Explanation:
As we know that the forces that act on the ladder is given as
1) friction force
2) Normal force at the ends of the ladder
3) Weight of the person standing on the ladder
4) Weight of the ladder
So here we know that our reference point is at the bottom position of the ladder
So we will have
Torque due to weight of the person and weight of the ladder is counter balanced by the torque due to normal force and torque due to friction force
So here we have
clockwise torque is due to weight of the person + weight of the ladder
Answer:
B will take 1.034 times the time of A from Boston to Hartford.
Explanation:
Let the distance from Boston to Hartford be S.
Person A drives at a constant speed of 55 mph for the entire trip,
Time taken by person A
Person B drives at 65 mph for half the distance and then drives 45 mph for the second half of the distance.
Time taken by person B
Ratio of time of arrival of B to A
B will take 1.034 times the time of A from Boston to Hartford.
