Block a is placed on a rough surface inclined at an angle ○ above the horizontal a taut string connects block A over a pulley top block B, which hangs from the string, as shown below. The massrd of blocks a and b are Ma and Mb respectively. The two blocks eventually stop and reverse direction. Which of the following graphs best predicts the acceleration of block a as it moved up and down the rough inclined surface

What is a carrier wave and how does it affect what you hear on the radio

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?
