tiana's little sister sits 1.2m from the pivot of a see-saw. her mass provides a force of 200N. tania pushes down on the other end of the seesaw to a ke it balanced. the maximum pushing force she can provide is 100N. how far from the pivot must Tania push to make the seesaw balanced

Use the empirical rule. the mean speed of a sample of vehicles along a stretch of highway is 70 miles per hour, with a standard deviation of 4 miles per hour. estimate the percent of vehicles whose speeds are between 66 miles per hour and 74 miles per hour. (assume the data set has a bell-shaped distribution.)

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
