What is the theoretical value for the speed of sound in a room at 24?

Which type of electromagnetic radiation carries the most energy and has the highest frequency?

The difference between experimental technique and procedure

1. Suppose that you have a mass of 45.7 kg and are standing on frictionless roller skates. Someone then throws you a 2.50 kg mass with a velocity of 14.5 m/s and you catch it. What will be your resultant velocity? (0.75 m/s)

The Moon does not crash into the Earth because: (a) the net force on it is zero. (b) it is beyond the main pull of the Earth's gravity. (c) it is being pulled by the Sun as well as by the Earth.

When you perform an experiment it is important the measurements are accurate what determines the accuracy of a measurement? A. How close it is to the actual value. B. The number of times that it is repeated. C.

You can identify a pure substance if you know it's?

A rod of mass M and length L can rotate about a hinge at its left end and is initially at rest. A putty ball of mass m, moving with speed V, strikes the rod at angle θ from the normal and sticks to the rod after the collision.

A satellite with a mass of 2,000 ㎏ is inserted into an orbit that is twice the Earth' s radius. W hat is the force of gravity on the satellite? The radius of the Earth is 6380 km, and the mass of the Earth is 5.98 X 1024 kg a. 2,000 N h.

our canisters contain helium gas. If all the canisters had the same amount of particles, which canister would have the fastest moving particles?

The acceleration due to gravity is
