Rose has been working as a receptionist for 20 years. One day, she receives a check in the mail for $750,000-an inheritance from a distant relative.

A 2 µC charge q1 and a 2 µC charge q2 are 0.3 m from the x-axis. A 4 µC charge q3 is 0.4 m from the y-axis. The distances d13 and d23 are 0.5 m. Find the magnitude and direction of the resulting vector R. Round your answer to the nearest tenth.

Two metal balls have charges of 7.1 * 10-6 coulombs and 6.9 * 10-6 coulombs. They are 5.7 * 10-1 meters apart. What is the force of interaction between the two balls? (k = 9.0 * 109 newton·meters2/coulomb2)

The probability that a battery will last 10 hr or more is 0.8, and the probability that it will last 15 hr or more is 0.11. Given that a battery has lasted 10 hr, find the probability that it will last 15 hr or more

What is the sum of 9260 and 3240? Express your answer numerically to at least three significant figures.

What could you do if the plant is placed in your community and later leads to pollution beyond the amounts allowed by the EPA?

The friends now feel ready to try a problem. Suppose an Atwood machine has a mass of m1 = 2.5 kg and another mass of m2 = 8.5 kg hanging on opposite sides of the pulley. Assume the pulley is massless and frictionless, and the cord is ideal.
