Your temperature is 98.6°F. Assuming your skin is a perfect radiator (ε = 1), determine the wavelength corresponding to the largest intensity (in μm).
What is the maximum kinetic energy (in eV) of a photoelectron emitted from a surface whose work function is 5.0 eV when illuminated by a light whose wavelength is 200 nm?
The light intensity incident on a metallic surface produces photoelectrons with a maximum kinetic energy of 2 eV. The light intensity is doubled. Determine the maximum kinetic energy of the photoelectrons (in eV).

I will downvote and report if its just a copy and paste or not completed

It is commonly believed that the mean body temperature of a healthy adult is 98.6 F. You are not entirely convinced. You collected data using 43 healthy people and found that they had a mean body temperature of 98.21 F with a standard deviation of 1.14 F. Use a 0.05 significance level to test the claim that the mean body temperature of a healthy adult is not 98.6 F. Please do not use a table, use calculator.

The average body temperature for healthy adults is 98.6 °F. Is this statement true? Do all healthy people have exactly the same body temperature? A study was conducted a few years go to examine this belief. The body temperatures of n = 130 healthy adults were measured (half male and half female). The average temperature from the sample was found to be x̄ = 98.249 with standard deviation s = 0.7332. Do these statistics contradict the belief that the average...

It has long been stated that the mean temperature of humans is 98.6 degrees F. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6 degrees F. They measured the temperatures of 44 healthy adults 1 to 4 times daily for 3 days, obtaining 200 measurements. The sample data resulted in a sample mean of 98.3 degrees F and a sample standard deviation of 1 degrees F. Use the P-value approach...

Language C++ Most people know that the average human body temperature is 98.6 Fahrenheit (F). However, body temperatures can reach extreme levels, at which point the person will likely become unconscious (or worse). Those extremes are at or below 86 F and at or above 106 F. Write a program that asks the user for a body temperature in Fahrenheit (decimals are ok). Check if that temperature is in the danger zone (for unconsciousness) or not and produce the relevant...

1. Many health care workers believe the mean body temperature of healthy adults is 98.6 degrees Fahrenheit. Philip A. Mackowiak, a doctor at the University of Maryland Center for Vaccine Development, suspects this number might be incorrect. (Source: Journal of the American Medical Association (268) pp. 1578-1580.) a) Determine the null and alternative hypotheses. b) Sample data indicated that the null hypothesis should be rejected. State the conclusion of the researcher. c) Suppose the mean body temperature of healthy adults...
