AIt depends.Would you be taking Physics B or Physics C?Physics C is Calculus based, and if you don't like Calculus you should definitely not go into Physics C.But Physics B is non-Calculus based. HOWEVER, Calculus concepts do help you as you continue studying Physics.I don't know what Math you have gone up to, but I would suggest that you take Calculus and Physics C simultaneously, OR take Physics B if you want an easier time.

AOk, it's been a real long time so I had to pull out the formulas and this is what I came up with.a. f = 20 O = 40 I = 40 M = -1b. f = 20 O = 20 I = 0 M = 0c. f = 20 O = 10 I = 20 M = -2a. 1 / I + 1 / 40 = 1 / 20 1 / I = 1 / 20 - 1 / 40 1 / I = 1 / 40 I = 1 / .025 I = 40 M = - I / OM = - 40 / 40M = -1b. 1 / I + 1 / 20 = 1 / 20 1 / I = 1 / 20 - 1 / 20 1 / I = 0 M = - I / O M = - 0 / 20 M = 0 c. 1 / I + 1 / 10 = 1 / 20 1 / I = 1 / 20 - 1 / 10 1 / I = - 1 / 20 I = 1 / .05 I = 20 M = - I / OM = - 20 / 10M = - 2 I could have missed the boat entirely, but, here's the math. Work it yourself and check.Hope it helps!!

AIn elastic collision, both kinetic energy and momentum are conserved. In an elastic collision between two bodies of equal masses, the velocities get exchanged. In our case since the second body initially was at rest, after collision, the first body comes to rest transferring 100% of its kinetic energy to the second body!

AThis is a pretty rudimentary physics equation. If you don't know how to figure it, you need to stop posting your homework questions online and start reading your textbook. You're going to have a hell of a time in class if you're stumped at such a fundamental level.

Ayou need to apply an equal and opposite force! thats how stabaling works! make your rseultant force = 0.

AX-rays.Microwaves and infrared are too well absorbed by metals to be of much use. They simply build up heat or make the electrons crazy. So to speak.X-rays, from decaying radioactive material, can be very good at detecting tiny flaws in metal parts, especially in welds of metallic pieces.

ABig tires. They spread the weight out. So the pressure on the mud is actually less.

AThe whole wavelength. Then everything will be exactly doubled.If they are offset by half the wavelength, for sinusoidal waves they will be completely cancelled out. (Results vary for other waveforms.)
