A wheel accelerates from rest with a 4 rad/s^2. How many revolutions are experienced in 6 seconds

Answers

Answer 1

Answer:

Revolutions = θ = 11.47

Explanation:

Given that:

Angular acceleration = α = 4 rad/s^2

As the wheel starts from rest so, ω₀ = 0

Time = t = 6 seconds

So we have to calculate revolutions per second, we know that:

θ = ω₀ t + 1/2 ( α * t ^2)

By putting values:

θ = 0 * 6 + 1/2(4 * (6^2))

θ = 0 + 2* 36

θ = 72

As the rotation angle is 2π, the revolutions will be calculated as:

s = θ / 2π.

By putting values:

s = 72/2(3.14)

s = 72/6.28

s = 11.47

So, there will be 11.47 revolutions in 6 seconds.

i hope it will help you!

Remy is smoking too closely to a building that manufactures fertilizer. When he puts out his cigarette near the hazardous waste, it sparks a fire because the fertilizer is flammable. What kind of hazard did the chemical waste cause?

Answers

Final answer:

Hazardous waste caused a flammable hazard due to chemicals that can burn easily and give off harmful fumes.

Explanation:

Hazardous waste from the building that manufactures fertilizer caused a flammable hazard when Remy put out his cigarette near it, sparking a fire. The release of chemicals that can burn easily and give off harmful fumes illustrates the dangers of flammable waste in chemical environments.

The hazardous waste in this scenario caused a physical hazard by igniting due to its flammability when exposed to the heat source from Remy's cigarette.

Because of its flammability, the hazardous material presented a physical risk and when it came into contact with Remy's cigarette's heat source, it caught fire. When flammable materials—like the fertilizer—come into touch with an ignition source—like a spark, they have the ability to fire quickly.

This incident emphasises how crucial it is to handle and store hazardous items properly in order to reduce risks and avoid accidents. It also emphasises the necessity of stringent safety procedures and laws in order to reduce the risk of fires and safeguard people and property.
