Answer:
a) Magnitude of the average velocity from t = 0 to t = 2 s = 2.24 m/s
b) Magnitude of the average velocity from t = 0 to t = 5 s = 3.16 m/s
Explanation:
a) Velocity is rate of change of position.
A particle's position coordinates (x, y) are (1.0 m, 3.0 m) at t = 0
A particle's position coordinates (x, y) are (5.0 m, 5.0 m) at t = 2.0 s
Displacement = (5-1)i + (5-3)j = 4i + 2j
Change in time = 2s
Velocity
Magnitude of velocity
b) Velocity is rate of change of position.
A particle's position coordinates (x, y) are (1.0 m, 3.0 m) at t = 0
A particle's position coordinates (x, y) are (14.0 m, 12.0 m) at t = 5.0 s
Displacement = (14-1)i + (12-3)j = 13i + 9j
Change in time = 5s
Velocity
Magnitude of velocity
Answer:
Charge, q = 900 C
Explanation:
It is given that,
Current flowing through the circuit, I = 6 A
Time for the flow of current, t = 2.5 minutes = 150 seconds
We have to find the charge delivered to this circuit. The total charge per unit time is called the current flowing through the circuit. It q is the charge flowing, then :
q = I × t
q = 6 A × 150 s
q = 900 coulomb
So, 900 coulomb of charge is delivered to this circuit.
