The cable at left exerts a -30 N force. This is T1. On your paper, draw a force diagram showing the three forces. a) Write the equation for the sum of the forces in the x-direction. What is the value of T2 in N (round to the nearest tenth)?

Acube has a volume of 2011 cubic inches. what is the angle measure between a side of a cube and its interior diagonal?

An object weigh 40n in air ,weigh 20n when submerged in water,and 30n when submerged in a liquid of unknown liquid density.what is the density of unknown of liquid?

(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.)
