(a) A line with a slope of 3, passing through the point (5,5)
(b) A horizontal line with a y-intercept of 8.
(c) A line that passes through the points (11,8) and (12,3)
(d) A horizontal line y=3


How would you define these functions? Thanks soooo much for the help! :)

A 75.0- man steps off a platform 3.10 above the ground. He keeps his legs straight as he falls, but at the moment his feet touch the ground his knees begin to bend, and, treated as a particle, he moves an additional 0.60 before coming to rest.

The gravitational force between a pair of neutron stars is 300 N when they are separated by a distance of 10,000 m. What would the attractive force be if the distance was increased by a factor of 3?

I tried 300 N / 3(10,000m)^2 = .000001 N
or do you take half of 10,000 for the radius so it is
300 N / 3(5,000m)^2 = .000004 N
or am I doing it wrong?? Please let me know thanks

I am making a drinking apparatus for a party. I have punch in a bowl. It is siphoned from there through a small rubber hose. That hose drains into a glass beaker with a burret on the bottom that the kids can turn on and off to get the punch out of the beaker. The problem is that the punch fills up the beaker and doesnt stop. HOW do i make it stop and fill up only part of the beaker? Any ideas please help!

Please help! I can't figure this one out.

The gap between electrodes in a spark plug is 0.045cm . To produce an electric spark in a gasoline-air mixture, an electric field of 2.2 X 10^6 V/m must be achieved. On starting a car, what is the magnitude of the minimum voltage difference that must be supplied by the ignition circuit? Answer in units of V.

When something is different about a chicken other chickens peck and peck at that difference. People seem to do the exact samething to other people. Any thoughts about this?

hey im doing this project for my biology class, and we need to create an analogy of an animal/plant cell is like a ___________ ? i need help thinking of ideas

also, if you can think of analogies that have to do with the main subject, and apply it to things like "nucleous" or "endoplasmic reticulum" or "golgi complex" or "ribosomes" etc

thanks:]
