The average current passing through a device is given by:
I = Q/Δt
I is the average current
Q is the amount of charge that has passed through the device
Δt is the amount of elapsed time
Given values:
Q = 4.00C
Δt = 4.00hr = 14400s
Plug in the values and solve for I:
I = 4.00/14400
I = 0.000277777778A
I = 0.278mA
Answer:
The laptop battery is capable of supplying 253980 J.
Explanation:
Given;
voltage of the battery, V = 11.4 V
power consumed by the laptop, P = 8.3 W
duration of the battery before depletion, t = 8.5 hours
Determine the amount of energy supplied by the laptop battery within 8.5 hours.
Energy, E = Power x time
Energy, E = 8.3 W x 8.5 h = 70.55 Wh
Energy, E in joules = 70.55 wh x 3600 s/h = 253980 J
Therefore, the amount of energy supplied by the laptop battery within 8.5 hours is 253980 J.
Answer: Distance is the actual position traveled by an object. Displacement is the shortest distance covered by the object.
Explanation:
Distance is the actual length covered by an object from one position to another. It is a scalar quantity. It cannot be negative.
Displacement is the shortest distance covered by the object. The displacement can be calculated by subtracting initial distance from the final distance. It is vector quantity. The displacement covered by an object can be zero, negative and positive.
Suppose, the boy travels from home to school then come back to his home. The distance between from his home to his school is 3 km.
In this case, the boy covers the total distance from home to school then to home is 6 km. But the displacement is zero because he comes to same position.
It’s not arrested because if you look closer it’s plug walk I don’t even understand how it talk tho
Answer:
42.417 cm³
Explanation:
The formula to find the volume of a cone is :
V = × π r² h
Here,
r ⇒ radius ⇒ 3 cm
h ⇒ height ⇒ 4.5 cm
<u>Let us find it now.</u>
V = × π r² h
V = × π × 3 × 3 × 4.5
V = × π × 9 × 4.5
V = × π × 9 × 4.5
V = × π × 40.5
V = × 3.142 × 40.5
V = × 127.251
V = <u>42.417 cm³</u>
