Two glasses of liquid with the same volume are mixed together inside an isolated system. One glass is initially at 45 °C and another one is at 4°C. Calculate the final temperature of the liquid. (Cliquid= 2,000 J/kg.°C)

How much work would be needed to raise the payload from the surface of the moon (i.e., x = r) to an altitude of 5r miles above the surface of the moon (i.e., x = 6r)?

Aresearcher plans to conduct a test of hypotheses at the 1% significance level. she designs her study to have a power of 0.90 at a particular alternative value of the parameter of interest. the probability that the researcher will commit a type ii error for the particular alternative value of the parameter at which she computed the power is: a. 0.90. b. 0.01. c. 0.10. d. equal to 1

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
