what happens to the acceleration (of a ball going around in a circle tethered to a string) if: 1) radis of the circle halves and the period of rotation stays the same 2) the peiod of rotation halves and the radius stays the same 3) the period doubles and...

Suppose you want to add a sprinkler system, and the location of one section of the sprinkler line can be described by the equation .

this is my last questions and I'm stumped can someone help, if not I'll continue You recently started the paperwork to purchase your new home, and you were just notified that you can move into the house in 2 weeks. You decide to hire a moving company, but...

Two tiny conducting spheres are identical and carry charges of -20.0 μC and +50.0 μC. They are separated by a distance of 2.50 cm. (a) What is the magnitude of the force that each sphere experiences, and is the force attractive or repulsive? (b) The spher...

A spring with an unstrained length of 0.074 m and a spring constant of 2.4 N/m hangs vertically downward from the ceiling. A uniform electric field directed vertically upward fills the region containing the spring. A sphere with a mass of 5.1 X 10^3 kg a...

My homework question is to find the Laplace transform of the function f(t)=e^(10-2t)*step(t-5). I am not sure how to handle the e^(10-2t) portion of the equation. Thanks in advance.

I think this question is ridiculous it should at least tell where to find the information. Encarta built into my word program does not even recognize Orientalism as a word so that should tell us something.

so.... e^10 (e^-2t) (1/s+5)?

or is it: (e^10)(e^-2t)((e^-5t)/s) = (e^(10-7t))/s?
