In the following equations, the distance x is in meters, the time tin seconds. and the velocity v is in meters per second. whatare the SI units of the constants c1 andc2?
a. x = c1 +c2t
b. x = .5c1t^2
c. v^2 = 2c1x
d. x = c1cosc2t
e. v^2 =2c1v-(c2x)^2
I don't know how to figure this out. Help would be soonice

Another question.

an iron nucleus has a radius of 5.4 X 10^ -15 meters and a mass of9.3 X 10^-26 kg. a) what is its mass per unit volume inkg/m^3?
b) if earth has the same mass per unit volume, what would be itsradius? mass of the earth is 5.98 X 10^24kg.

If anyone can help I would sooo appreciate it! you would be alifesaver! thanks!

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.
