osciillating on the moon that has the same period as a 4.87 m pendulum oscilating on Earth. If the moon's gravity is one-sixth of the Earth's, what is the length of the pendulum on the moon (in units of m)??

Instead of building something to encase the egg, we need to build something to drop the egg into from various heights. It can't be more than 17"x17" x 7cm height to cushion the impact. The egg will be dropped from 2 meters, 3 meters etc... What are good ways to cushion the fall to prevent the egg from breaking upon impact?

I used an ohmmeter on the 200 ohms setting. How would i change the following readings to conductivity since an ohmmeter measures resistance. The readings are .3, .4, .5, .6, .7, .8,.9,.10,.11.


Please tell me what the appropriate conductivity readings are after converting it from resistance. Can you also include what the units will be. THanks. i really appreciate it.

On my ohmmeter this is a section with the following values. 2000k, 200k 20k, 2000 with a horseshoe sign next to it, and 200. I used the one with the 200. I want to know what unit this is and how should i write it. I know the other ones but the 200 on its own i dont know what it stands for

Thanks for your help

What mass of steam initially at 150 degrees C is needed to warm 180 g of water in a 100 g glass container from 20.0 degrees C to 53.0 degrees C?

I have found the specific heats of the materials. I thought I should use Q=(m)(c)(delta T), but I can't figure out how to do that without the initial mass of the steam. Please help!

I am in the process of doing a project for a science fair exhabition and I'm interested in finding out as part of my project how I might be able the make a simple bar-magnet levitate through a series of magnetically charged coils (electromagnetic of course). Basically I'm trying to find out info about the circutes I might need and also the find out about the meterials I might need. I would be grateful if you could give me any info at all, even if you have info about URL's I might be able to go to on this subject. Thank for your help.

a. What pressure does it exert on the floor?

b. If it is turned so that the 5 cm and 2 cm sides are in contact with the floor, will the pressure on the floor be increased or decreased?




What volume will a gas occupy at 975 millimeters of pressure if the gas occupies 525 cubic cm at 650 cimllimeters of pressure?







A container with equal sides of 10 cm is filled with 500 grams of fluid.

a. What is the force in newtons on the bottom of the container?

b. What is the density of the fluid in per cubic cm?

c. what is the pressure on the bottom of the container in newtons per square cm?
