Assume that the solar radiation incident on earth is 1330 w/m2 (at the top of the atmosphere). find the total power radiated by the sun, taking the average separation between earth and the sun to be 1.489 × 1011 m. answer in units of w.

Experiment scenario 2: a biology student wants to conduct a study of how the amount of food affects the weight gain for mice. i have set up four cages with a mouse in each cage. fill in the boxes that would allow the biology student to complete the study correctly

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
