You are given a sample of metal and asked to determine its specific heat. you weigh the sample and find that its weight is 28.4 n. you carefully add 1.25 x 104 j of heat energy to the sample and find that its temperature rises to 18.0 °c. what is the sample’s specific heat?
The specific heat of the given sample of metal is 14.32 J/kg.K.
What is the Specific heat of a sample?The specific heat of a sample is the amount of heat needed or required to raise the temperature of that sample by 1K. It is given by the formula:
Q = mCΔT
where;
Q = Heat transferredm = Mass of the substanceC = Specific heat ΔT= Change in temperature.Recall that:
weight of a substance = mass × gravity
mass = 28.4 N/ 9.8 m/s²mass = 3 N/m/s² = 3 kgFrom the equation:
Q = mCΔT

Why do molecules have the most variation in their properties
Answer:
Timing and energy are also factors in isomerism. Molecules are mobile entities, undergoing all sorts of rotational motions that change their shapes, and those motions require energy. Thus, some molecules can be the same on one timescale or set of energy conditions but different, or isomeric, on others.

The finishing times of a 5k race run by competitive male runners age 15-18 are approximately normal distribution with a mean time of 18 minutes and a standard deviation of 2 minutes. a particularly tough 5k race tends to take these same runners 4.5 additional minutes. to earn a completion medal in this particular 5k race, the runner must complete the race within 25 minutes. approximately, what percent of competitive male runners in the 15-18 age bracket typically do not earn a completion medal at this race?
Using the normal distribution, it is found that 0.1056 = 10.56% of runners do not earn the competition medal.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, considering the 4.5 additional minutes, the mean and the standard deviation are given, respectively, by:
[tex]\mu = 22.5, \sigma = 2[/tex].
Runners that take more than 25 minutes to complete the race do not earn a medal, hence the proportion is one subtracted by the p-value of Z when X = 25, so:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{25 - 22.5}{2}[/tex]
Z = 1.25
Z = 1.25 has a p-value of 0.8944.
1 - 0.8944 = 0.1056.
0.1056 = 10.56% of runners do not earn the competition medal.

A varicocele is an abnormal enlargement and tortuosity of the spermatic cord veins. Although varicoceles are frequently discovered during routine physical examinations and are common in the general population, they are the most frequently treatable cause of male factor infertility.
In the veins located in the scrotum, directly above the testicles, it is thought that varicoceles are brought on by faulty valves. These valves typically control how much blood is sent to and received from the testicles. Blood backs up when normal flow doesn't happen, which causes the veins to enlarge.
