Answer:
The amount of electrons that flow in the given time is 3.0 C.
Explanation:
An electric current is defined as the ratio of the quantity of charge flowing through a conductor to the time taken.
i.e I = ...................(1)
It is measure in Amperes and can be measured in the laboratory by the use of an ammeter.
In the given question, I = 1.5A, t = 2s, find Q.
From equation 1,
Q = I × t
= 1.5 × 2
= 3.0 Coulombs
The amount of electrons that flow in the given time is 3.0 C.
<u>Answer:</u>
950-kg subcompact car be moving to have the same kinetic energy of truck at 116.08 km/hr
<u>Explanation:</u>
Kinetic energy of body with mass m and moving at velocity v is given by
KE of truck
KE of subcompact car
Equating
So 950-kg subcompact car be moving to have the same kinetic energy of truck at 116.08 km/hr
