A mass, m1= 5.50 kg , resting on a frictionless horizontal table is connected to a cable that passes over a pulley and then is fastened to a hanging mass,
10.96 kg, as in the figure. When we release the mass m1, it
accelerates across the table. Find (a) the acceleration of the masses and
(b) the tension in the cable. Neglect the mass of the cable and pulley. Hint:
Draw a free-body diagram of each mass.

Which of the following is considered to be a vector?               a.  temperature    b.  velocity    c.  time    d.  mass

An object of dimensions 50 cm x 40 cm x 0.20 cm has a mass 60g. find its density in g/cm3 and kg/ m3

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
