All I know that K-theory is like something dealing with physics, kinectics, velocity, math, at stuff like that.

Hi, I need to draw a venn diagram for linear and non linear motion. Basically putting the differences on the end part of the circle and the similarities in the middle. It's for my 9th grade physics class

An aluminum conductor (resistance 50 ohms, mass 15g, specific heat capacity 0.215) in plced in liquid N2 (-195.8C). How much N2 will evaporate while the resistor cools from 20 deg C to the N2 temp?? The conductor is not connected to a power source and the container is NOT insulated. (This is an ALGEBRA based physics question).
So far I have tried: deltaQ=mass x sp. heat of aluminum x deltaT
AND deltaQ=the latent heat of vaporization of N2 (47.8) x delta mass.

Sadly (and not surprisingly for me...neither works out).

Any help would be greatly appreciated.

A 8.50 kg block (m1) and a 7.55 kg block (m2) rest on a horizontal frictionless surface with m2 resting on top of m1. The surface between the top and bottom blocks is roughened so that there is no slipping between the two blocks. A 42.6 N force is applied to the bottom block.

I determined the accelertation of the two block system to be 2.65 m/s^2, but help on how to solve these questions would be appreciated:

What is the force of static friction between the top and bottom blocks? (Friction is supplying the net force on the top block.)

What is the minimum coefficient of static friction necessary to keep the top block from slipping on the bottom block? (The frictional force is a function of the weight of the top block)

A cannonball is shot from a hill 10 meters higher than the surrounding ground.

a. If the firing trajectory is 0 degrees from the horizontal, and the firing velocity 50 m/sec, how far will the cannon ball travel?
b. If the cannon’s trajectory is 30 degrees instead, how far will the cannon ball travel now?
c. If the cannon’s trajectory is 45 degrees how far will its range be?
d. If the cannon is moved to level ground and fired at 45 degrees, how far will its range be?

I don't know what equations should be used for this problem and have no idea where to start. Any help would be great.
