Answer:
absorbs heat and its kinetic energy increases.
Explanation:
As we know that heat is defined as the change in the temperature as there is increase in the temperature change then the heat will increase or decrease with respect to increase or decrease in temperature change.
In the given, question temperature is changing from 20° to 50° which means there is increase in the temperature which results in the absorption of heat. And increase temperature will increase the average speed of the molecules which results in increase in kinetic energy.
Explanation:
Below is an attachment containing the solution.
Answer:
See explanation below
Explanation:
The equation to use for this is the following:
dU = q + w
As the heat is being release, this value is negative, and same here happens with the work done, because it's in the surroundings.
Therefore the change in the energy would be:
dU = -2.59x10^4 - 6.46^4
dU = -9.05x10^4 kJ
Answer:
25.25%
Explanation:
Mean diameter (μ) = 0.35 inches
Standard deviation (σ) = 0.03 inches
For any given diameter, X, the z-score is given by:

For X= 0.37 inches:

A z-score of 0.6667 is equivalent to the 74.75-th percentile of a normal distribution.
Therefore, the percentage of bolts that will have a diameter greater than 0.37 inches is:
