 Question 590827: QUESTIONS: 1. The density of a cube is given by: d=ms^-3 where m is the mass of the cube (in grams) and s is the length of a side (in centimeters). 1(a) Solve the equation for s. 1(b) A cube of ice has a mass of 7.336 grams and a side length of 2 centimeters. Use the equation to find the density of the ice. 1(c) Use the value of d you found in 1(b) to determine the side length for a cube of ice with mass 24.759 grams. 1(d) Use the value of d you found in 1(b) to determine the mass of a cube of ice with side length of 4 centimeters. MY ANSWERS: 1(a) I'm not exactly sure how to solve this one. 1(b) d=0.917 1(c) s=3 1(d) m=58.688 Click here to see answer by jim_thompson5910(28476)

 Question 590884: I am completely lost on this one,I know how to do the equations except for when it comes to the square root part. Can you give me an example or show me how to work it out please? 2. The time (in seconds) it takes a pendulum on a grandfather clock to swing back and forth once is given by T=6.28√(l/32) Where l is the length of the pendulum in feet. 2(a) Solve this equation for l. 2(b) Suppose it takes 2 seconds for the pendulum to swing back and forth once. How long is the pendulum? 2(c) Suppose a pendulum is 1.5 feet long. How long will it take the pendulum to swing back and forth once? 2(d) How many times will the pendulum in 2(c) swing back and forth in one minute? Click here to see answer by mananth(12270)
