Aconducting sphere of radius r1= 0.38m has a total charge of q=.75 uc. a second uncharged conducting sphere of radius r2= 0.28m is then connected to the first by a thin conducting wire. the spheres are separated by a very large distance to their size. what is the total charge on sphere two, q2, in c?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
