Your grandmother in Ireland sends you her favorite cookie recipe. Her instructions say to bake the cookies at190.5°C. To what Fahrenheit temperature would you set the oven to bake the cookies?

Answer: Here's my answer, I made it step-by-step so you can understand it! <3

Explanation:

To find the centripetal acceleration of the tip of the fan blade, we can use the formula for centripetal acceleration:

a = (v^2) / r

where:

a is the centripetal acceleration,

v is the linear velocity, and

r is the radius of the circular path.

Given that the fan completes 2 rotations every 1.0 second, we can find the angular velocity (ω) using the formula:

ω = (2π * n) / t

where:

ω is the angular velocity,

π is a constant (approximately 3.14),

n is the number of rotations (2),

and t is the time taken (1.0 second).

Substituting the values into the formula, we have:

ω = (2π * 2) / 1.0 = 4π rad/s

Next, we can calculate the linear velocity (v) using the formula:

v = r * ω

Substituting the given radius value (0.61 m) and the angular velocity we found earlier, we have:

v = 0.61 * 4π = 2.44π m/s

Finally, we can calculate the centripetal acceleration (a) using the formula:

a = (v^2) / r

Substituting the linear velocity and the radius, we have:

a = (2.44π)^2 / 0.61 = 5.88π^2 / 0.61 ≈ 96 m/s²

Therefore, the centripetal acceleration of the tip of the fan blade is approximately 96 m/s² (Option 4).

Radioisotopes used as tracers in the industry are a benefit associated with nuclear energy, therefore the correct answer is option B.

What is a nuclear power plant?

It is a particular kind of power plant where electricity is produced using a nuclear reactor that may use nuclear fusion or nuclear fission.

When a radioactive substance undergoes a nuclear reaction, a tremendous quantity of energy is produced. This energy is used to heat the water in the nuclear reactor, creating steam that is then pumped through a turbine to create electricity.

Humanity has come a long way in finding solutions to complex issues for the benefit of human society, as we can see how challenging it is to generate electricity from a trace amount of radioactive material.

Engineering-assisted applications of science are what fuel the advancement of human civilization.

The correct answer is option B because radioisotopes used as tracers in the industry are a benefit of nuclear energy.
