Answer:
E
Explanation:
A vector is a physical quantity that has magnitude and direction while a scalar is a physical quantity that has magnitude only
*electric potential is a scalar quantity because it only has magnitude
*electric field and electric force are vector quantities because they have magnitude and direction
Answer:
the charge generated in the circuit is 240 C.
Explanation:
Given;
current flowing in the circuit, I = 2A
time of current flow, t = 2 minutes = 2 x 60s = 120 s
The current flowing through a given circuit is defined as the quantity of charge flowing through the circuit in a given time.
where;
Q is the charge flowing in the circuit
Q = 2 x 120
Q = 240 C
Therefore, the charge generated in the circuit is 240 C.
Answer:
a) , b)
Explanation:
a) The maximum possible acceleration that the truck can give to the SUV is:
b) The equation of equilibrium for the truck is:
The force of the SUV's bumper on the truck's bumper is:
Electric field is defined as force per unit charge.
So it is given by
now we can find electric field by
So field strength is 0.75 N/C.
Formula : CaCl2
Eh hope this helps
