The way it rotates is Counter-clockwise
I’m assuming it’s A earth.
Answer:
This is a good experiment, however there are a few flaws
Explanation:
In this experiment, the battery is not replaced. Which can then affect the experiment if it had sustained damage from the failed attempts in the garage, and then being moved to the second scenario. Another possibility is that the battery was faulty from the start, which would definitely affect the results negatively.
Another flaw would be the temperature. The first scenario of a warm garage is fine, however after being moved to an environment below zero, the water in the car would have frozen, and many other systems would be impaired. Therefore the starting of the car would be influenced by more than just the battery.
Answer:
1 joule = 0.737 foot-pound
Joule is the unit of work.
1 J = 1 N·m
In SI units
1 J = 1 kg· m/s²
0.737 foot-pound is the amount of work to raise 0.737 pounds one foot or raising one pound to 0.737 ft.
Answer:
α = 3070rev/s^2
θ = 5541.66 revolutions
Explanation:
Given;
Operating angular speed w = 350000 rpm
time t = 1.9s
Angular acceleration = change in angular speed/time
Angular acceleration=350000rpm×1/60 min/sec ÷ 1.9s
Angular acceleration α = 3070rev/s^2
Number of revolutions θ = 1/2 × α × t^2
Since initial angular speed is zero
Substituting the values;
θ = 1/2 × 3070 × 1.9^2
θ = 5541.66 revolutions
