Astronomers estimate that the Sun has enough fuel for hydrogen fusion to last how many more years?

What kind of destructive force or forces will most likely change the way Stone Mountain looks over the next million years? A) volcanoes B) landslides C) erosion and weathering D) earthquakes and faulting

A wave has a wavelength of 12 mm and a frequency of 7 hertz. What is its speed?

A wire carries a current of 0.71 A. This wire makes an angle of 46° with respect to a magnetic field of magnitude 6.4 * 10-5 T. The wire experiences a magnetic force of magnitude 8.9 * 10-5 N. What is the length of the wire?

What is the relationship between mass and weight on earth?

In a food fight, two blobs of Jell-O collide and stick together. Initially, the 35.0 g blob was traveling at 9.60m/s to the right, and the 85.0 g blob was moving at 8.4 m/s to the left. What is the velocity of the new, larger blob?

According to Newton's first law of motion, what would happen to a car traveling at a constant velocity of 55 MPH to the west in the absence of an unbalanced force?

The Appalachian mountain range in the Eastern United States was once much taller than the Rocky mountain range in the Western United States.

Describe how lighting is just like you walking across a carpet and getting shocked

You need to raise a heavy block by pulling it with a massless rope. You can either (a) pull the block straight up height h, or (b) pull it up a long, frictionless plane inclined at a 15∘ angle until its height has increased by h.

A 320-m length of wire stretches between two towers and carries a 120-a current. determine the magnitude of the force on the wire due to the earth's magnetic field of 5.0 * 10-5t which makes an angle of 60 ∘ with the wire.
