A space traveller weighs herself on Earth at a location where the acceleration due to gravity is 9.83 m/s2 and finds a value of 549 N.
What is her mass ?The traveller travels to a planet in a neighboring solar system. It is a long trip, but she somehow manages to maintain her physical condition by conscientious exercise and diet control. The acceleration due to gravity on this planet is 13.1 m/s2.
What is the traveller's mass ′
on the planet?

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

What is a possible result of higher air temperature caused by global warming

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
