I read the Shakespeare has a much higher IQ than Einstein.
Einsteins IQ is only 160 and I forgot Shakespeares one but it was around 190 - 200.

Who was Smarter?

Can please someone tell me the answer to this question:

Regarding the theory of relativity developed by Einstein in 1905, which one of th e following statements is not true?

A. Einstein assumed that light always travels at a constant speed in vacuum of 299,792,458 or 3*108 m/s.

B. The relative mass m is always larger than the rest mass mo of any particle.

C. No particle or object can travel at a speed equal or greater than that of light.
D Energy released in a chemical explosion is proportional to the difference between the mass of all reactants and the mass of all
products.

E. The gain in kinetic energy by a particle can be achieved by losing its mass.

For example, a 1 kilogram object traveling at 10 meters per second will generate 10 newtons, but how would translate into pounds? You always hear things like thing in accidents and they say (not to this particular problem) that when they hit the wall their body's generated 1000lbs of force. How did they determine that (i am assuming with g-forces, but i don't know how to calculate that either)?

1) A 12 V automobile battery is connected to an electric starter motor. The current through the motor is 216 A. How much energy does the battery deliver to the motor each seconds? Answer in units of J.
I got 11.988 but Im not sure if I am correct.

2) If 5.4 x 10^21 electrons pass through a 10 resistor in 8 minutes, what is the potential difference across the, what is the potential difference across the resistor? Answer in units of V.

Assume that a steel pipe is embedded in the concrete floor of a bare room. The inside dia. of the pipe is .06 inches larger than the dia.of a ping-pong ball that is resting at the bottom of the pipe. You are in the room with 6 other people with the following objects: 100 ft of clothesline, A carpenter's hammer ,A chisel, A box of wheaties, A file, A wire coat hanger, A monkey wrench, A light bulb. List as many ways as you can think of to get the ball out of the pipe without damaging the ball,tube,or floor.

1) A dog walks at a speed of 1.8m/s along the deck toward the front of a boat that is traveling at 6.6m/s with respect to the water. What is the velocity of the dog with respect to the water? Wat if the dog were walking toward te back of the boat?
2) A vacationer walks 4km/h directly across a cruise ship whose speed relative to the earth is 13.2km/h. What is the speed of the vacationer with respect to the earth?
3)Two trains approach each other on parallel tracks. ach has a speed of 80km/h with respect to the earth. If they are initially 10km apart, how long will it be before they pass each other?

When General Relativity theory (GR) is mathematically mixed with equations for Quantum Mechanics (QMs), more often than not, infinities arise. Why? Could these infinities actually be useful information that is trying to communicate something significant about the laws governing nature? One has to wonder at just what point does GR breaks down when combining QMs? Is it at the atomic level, or on the order of molecules? Could it be that GR and QMs express the same information but in two different kinds of formats and, are just a duality of one another? If GR and QMs are just dualities with GR representing the large version of its duality, QMs; and, QMs representing the small version of its duality, GR, do we really even need to combine them to understand the forces in this universe? Could it be that GR and QMs are to each other what M-theory is to the 5 versions of string theory? The infinities may be telling us that we need to rethink our whole approach to GR/QMs unification.

earnshows theorem says that no particle can b in stable equilibrium under the action of electrostatic force alone. consider ,however, a positive point charge at the center of a square of four equal positive charges ,this point charge seems to b in stable equilibrium as all the four charges push it towards the center ,yet earnshows theorem holds,,, can u explain how?
