Can someone please help me with these equations for my Physics class I would really appreciate it.

1. A light bulb is found to have a current of 0.25 A when a voltage of 3.2 V is applied to it. Calculate the resistance in the light bulb.

2. Calculate the current in a wire that has 3.5 coulombs passing a fixed point every 12.0 seconds.

3. A current of 1.90 Amps is allowed to flow through a resistor for 30 seconds. Calculate how much charge pass through the process of torturing the 30.0 seconds.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
