Arod of length l and mass m rotates about an axis through its center (1 = ml) with angular velocity oa. a second rod with the same length and mass rotates about an axis through an endpoint (1 = ml) with angular velocity 03. they have the same rotational kinetic energy. which of the following is true? a) oa=0.250b c) oa = 2.00b b) oa = 0.500b d) oa = 4.00b

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?

What is the relationship between the direction of motion of the balloon and the wind currents

Agroup of monkeys is trying to cross the river in a rowboat. the maximum buoyant force on the rowboat is 2,000 n. the weight of the rowboat is 1,000 n. each monkey has a weight of 150 n. how many monkeys can safely cross in the rowboat at one time? explain your reasoning, including any calculations you used to find the answer.
