Physics
i still couldnt get the answer either

Physics
is Ma the mass of block a?

Physics
the knot is inbetween block b and the wall. block a hangs from the knot. the knot is connected to the wall by a rope attached to the wall at 30 degrees from the horizontal

Physics
Block B in the figure below weighs 713 N. The coefficient of static friction between block and table is 0.20. Assume that the cord between B and the knot is horizontal. Find the maximum weight of block A for which the system will be stationary.

college
the length of the top of a table is 3 m greater than the width. the area is 88m^2. find the dimensions of the table

math
(y plus 5)y^2 - 5y plus 25)

math
(y plus 5)y^2 - 5y plus 25)

chemistry
why is it important to record detailed observations, not just conclusions?

physics
Andy (mass 80 kg) uses a 3.0 m long rope to pull Bob (mass 60kg) across the floor (uk= .2) at a constant speed of 1.0 m/s. Bob signals to Andy to stop by plucking the rope, sending a wave pulse forward along the rope. The pulse reashes andy 150 ms later. What is the mass of th...
