Answer:
0.5 A
Explanation:
Current: This is defined as the rate flow of electric charge round a circuit,
The S.I unit of current is Ampere (A). Mathematically,
Current (I) = C/t
I = C/t................ Equation 1
Where C = capacity of the battery, t = time
Given: C= 3 Ah, t = 6 hours.
Substitute into equation 1
I = 3/6
I = 1/2
I = 0.5 A.
Hence the average current drawn = 0.5 A
Answer:
Plan A
Explanation:
Acceleration in a circle is toward the center of the circle, while velocity is always a straight line that's tangent to the circle. When the boy let's go of the rope the Acceleration toward the center of the circle disappears. The v ball then follows the straight path, tangent to the circle.
B they formed from the dense elements as compared to the others in the solar system
Answer:
a = -2.4 m/s²
Explanation:
Given,
The initial speed of the bus, u = 24 m/s
The final speed of bus, v = 12 m/s
Time taken to reach final speed is, t = 5.0 s
The acceleration of the body is given by the change in velocity by time
a = (v - u) / t
= (12 - 24) / 5
= -2.4 m/s²
The negative sign in the acceleration indicates that the bus is decelerating.
Therefore, the acceleration of the bus is, a = -2.4 m/s²
