Answer:
24.54 m
Explanation:
From the following equation of motion, we can calculate the time it takes for the swan to reach the speed of 4.7m/s from rest at an acceleration of 0.45 m/s2:
where v is the final speed, v0 = 0 m/s is the initial speed at rest, a is the acceleration and t is the time it takes
And the distance it covered within 10.44 s is
Answer:
The angular speed of the wheel is 0.452 rad/s
Explanation:
The angle through which the car wheel turns, Δθ = 277° = 277/360 × 2·π radian
The time it takes for the car wheel to turn, Δt = 10.7 s
The angular speed, ω is given by the following equation;
Substituting the known values for Δθ and Δt gives;
The angular speed of the wheel = 0.452 rad/s
Answer:
30 C
Explanation:
Given:
Current flowing in the circuit (I) = 50 A
Start-up time (t) = 0.60 s
Now, we know that, charge drawn in through a cross sectional area of the circuit is given as:
Where, 'q' is the amount of charge drawn, 'I' is the current and 't' is the start-up time.
Now, plug in 50 A for 'I', 0.60 s for 't' and solve for 'q'. This gives,
Therefore, the amount of charge drawn in the circuit at the start-up of the compressor of an air conditioner is 30 C.
