My Durango always seems to accumulate a lot of brake dust on the front wheels. I don't ride the brakes and it builds up quickly after washing. What could be causing this aside from using the brakes?

Also whenever it gets cold and it has been raining or even just misting, my brakes lock up when I apply them for about the first half mile after moving. What could cause this?

I own a 2001 Dodge Durango and I need to change/get some brake fluid and some tail lights(bulbs).

And I need to replace my head light bulbs.

My first ? is: What type of tail light bulbs do I need to get?

My second is: What type of brake fluid do I need to get?

And third: Can I get to the head light bulbs without having to take out the whole entire headlight? If so how and if not what will I need to do this?

I'm going to be visiting New York this week, and I was wondering what are some things I can't pass up seeing? I know I'm going to see a play on Broadway, and I'm going to Macy's, and I'm doing some other things.

Two objects with masses of 1.00 kg and 7.00 kg are connected by a light string that passes over a frictionless pulley

(a) Determine the tension in the string. ______ N

(b) Determine the magnitude of the acceleration of each mass. ______ m/s²

(c) Determine the distance each mass will move in the first second of motion if both masses start from rest. ______ m

A 3.0 x 10^-5 C is placed 1.0m from a 6.0 x 10^-6 C charge. Where will the electric field be zero?

I am not good at doing these.

A carbon-14 ion, with a -4 charge, is launched into a .50 T magnetic field at a velocity of 3.0 x 10^5 m/s in a direction perpendicular to the field. Calculate the radius of the particle's motion. A carbon-12 ion, with the same charge, is launched into the same field at the same velocity, what is the radius of this particle's motion?

It has been a while since I have done this, and I have lost my notes. So if you could explain how you get the answers, I would be very thankful.
