Physics 12 Review
End of the semester, working on the final review... I have a couple of questions I am stuck on right now. My notes on these questions seem to have vanished into the void... 1. "A 2.0kg puck travelling due east at 2.5m/s collides with a 1.0kg puck travelling due south at ...

Physics 12
"Two small spheres are located 0.50m apart. Both have the same charge on them. If the repulsive force is 5.0N, what charge is on the spheres, in microcoulombs?" I can begin to use my electrical force formula, but then I have two unknown charges. The anwser is 12 uC...

It's midterm time! Can anyone explain the NAD cycle to me in VERY SIMPLE TERMS or have a website that might do it? I keep reading through my notes but I just can't quite get it. Thank you!

Midterm review time! I just can't manage to get this question. "A 12kg shopping cart rolls due south at 1.5m/s, 30 degrees E of S. What is the magnitude of the change in momentum sustained by the shopping cart?" I know momentum equals the mass times the change in...

Read through the essay again and look for anything that jumps out at you. Concentrate on making the title reflect your main topic. For a researched paper, the title is often a little more dry and formal. For an informal essay, however, you can jazz it up a little. Try to make ...

Dog Breeds
Finally, one I can anwser! Actually, this dog would be listed under Group 1: Sporting Dogs by AKC standards. These cover retrievers and gun dogs. The varying Hound group covers anything from Salukis to beagles. Internationally, it would be listed under Group 8: Flushing dogs/...

Ohmygoodness, I am not having a good time tonight. "A 5.2kg block sliding at 9.4 m/s across a horizontal frictionless surface collides head on with a stationary 8.6kg block. The 5.20kg block rebounds at 1.80 m/s. How much kinetic energy is lost during this collision?&...

Oh goodness, another review question. "The 2.0kg head of an axe strikes a tree horizontally at 40 m/s. The blade penetrates 0.040 m into the tree. What is the average force exerted by the blade on this tree? Is this just net force? Why do they give you the distance the ...

This came up on our test review for tomorrow, and I'm stumped! "A hockey puck of mass 0.51 kg is moving north across the ice with a speed of 32 m/s. If it is hit with a hockey stick so as to make it travel due west at the same speed, what is the magnitude of the ...

Grade 12 Physics
Well, my final question before the big test, but this is messing me up in various assignment questions (rrrr). How do you find the magnitude of an object when friction is negligible? What is the actual definition of magnitude? I didn't take Physics 11, and this isn't ...

This question came up on my review package tonight, and it has me stumped. "A box of mass 14.5kg slides at a constant speed of 4.70m/s down a ramp at 35.3 degrees below the horizontal. What is the force of friction on the box?" I can calcuate force of friction on ...

"If a skier coasts down a slope at an angle of 24 degrees below the horizontal, what is her acceleration if the force of friction is negligible?" I must have done this question 15 times, and still can't get the right anwser. Can anyone help me?
