A machine is applying a torque to rotationally accelerate a metal disk during a manufacturing process. An engineer is using a gr

aph of torque as a function of time to determine how much the disk’s angular speed increases during the process.
The graph of torque as a function of time starts at an initial torque value and is a straight line with positive slope. What aspect of the graph and possibly other quantities must be used to calculate how much the disk’s angular speed increases during the process?

Explanation:

Question 9 A machine is applying a torque to rotationally accelerate a metal disk during a manufacturing process. An engineer is using a graph of torque as a function of time to determine how much the disk's angular speed increases during the process The graph of torque as a function of time starts at an initial torque value and is a straight line with positive slope. What aspect of the graph and possibly other quantities must be used to calculate how much the disk's angular speed increases during the process? The slope of the graph multiplied by the disk's radius will equal the change in angular speed The area under the graph multiplied by the disk's radius will equal the change in angular speed. The slope of the graph divided by the disk's rotational inertia will equal the change in angular speed. The area under the graph divided by the disk's rotational inertia will equal the change in angular speed. The area under the graph multiplied by the disk's rotational inertia will equal the change in angular speed E

Answer:

(D) The area under the graph divided by the disk's rotational inertia will equal the change in angular speed.

Explanation:

Angular momentum is equal to the product of rotational inertia and angular speed. Therefore, angular speed would be angular momentum divided by rotational inertia.

Torque is the slope of angular momentum, so the area under the torque curve would be equal to the angular momentum.

In conclusion, the angular speed would be the area under the torque curve divided by the rotational inertia.

Hope this helps!

On a day when the temperature reaches 50°F, the temperature in degrees Celsius is: 20°C
anzhelika [568]

Answer:

10°C

Explanation:

To convert °F to °C, we use the formula:

°C =  (°F - 32) * ( 5/9)

So, to convert 50°F to the equivalent  in °C, we can proceed as follows:  

°C = ( 50 - 32 ) * (5/9)  

°C = ( 18 ) *  (5/9), which is, approximately,

°C = 9.999999999... ≈ 10 (5/9 ≈0.555555...)

So, 50°F is equivalent to 10°C.

A hypothesis that survives peer review receiving similar results and has predictive capabilities a Fact a) Theory b) a Law an Ax
MaRussiya [10]

Answer:

The correct answer will be option-B.

Explanation:

A scientific hypothesis is the proposed perdition or idea which is based on the earlier works and knowledge related to the scientific issue. The hypothesis can be tested and proved on the basis of the experiments.

The proved hypothesis can either become law or theory after peer-reviewed by fellow scientists. If the hypothesis still has predictive capabilities help form another hypothesis. Such statements are known as the "theory".

Thus, Option-B is the correct answer.

Which has more energy for erosion? A. fast-moving stream B. slow-moving creek C. lake D. rainfall
Rufina [12.5K]
A. A fast moving stream. Water has erode Earth for thousands of years. This was what caused the Grand Canyon. A faster ,owing stream would cause a faster erosion due to the speed and strength of the water itself.
