A student uses a meter to measure 120 coulombs flowing through a circuit in 60 seconds. The electric current in this circuit will be 2 A
Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere, symbolized by A.
current = charge / time
given
time = 60 seconds
charge = 120 Coulombs
current = Q / T = 120 / 60 = 2 A

Answer:
Net force ( F ) = 208 N.
Speed of car ( v ) = 68.58 m/s.
Explanation:-
The radius ( r ) = 480 m.
Mass of passenger ( m ) = 65 kg.
Horizontal force ( 
) = 208 N.
Vertical force ( 
) = 637 N.
Net vertical component of force ( ) = m*g - 637 = 65 * 9.8 - 637 = 0 N.
a ) magnitude of net force .
= 208 N.
b) The speed of car.
where v is the velocity.
v² = 4704
v = 68.58 m/s.
Answer:
D. The cart is moving at a constant speed or velocity
Explanation:
Equilibrium is a state of body in which it is either at rest or moves with uniform velocity. The sum of forces acting on such a body is always zero and the sum of all the torques acting on it is also zero.
There are two types of equilibrium as follows:
Static Equilibrium: When a body is at rest it is said to be in static equilibrium.
Dynamic Equilibrium: When a body is moving with constant velocity, then it is said to be in dynamic equilibrium.
Hence, the correct option here will be:
<u>D. The cart is moving at a constant speed or velocity</u>
My height is 178 centimeters.
My weight is 700N.
A) Electrons in a series circuit travel in one path, and if the path or wire is broken, the current has no other path to travel, and the circuit does not work. Hope this helps!
