Does anyone know what types of forces are in work between the time when the golfer hits his club towards the golf to the end when the golf ball goes into the hole? Thank you.

Ok, it's a measurement, but of what exactly? We take time for granted as if it is something, yet is not an object, an energy or even a force like gravity. Newton thought it was fixed, Einstein found it relative, Quantums puts it on LSD and Strings make it whatever you want it to be. From 2 year olds holding up 2 fingers to theoretical physists we all acknowledge time. Yet, think about it: What exactly is TIME?

A 1.25-kg object is moving in the x direction at 17.4 m/s. Just 3.41 s later, it is moving at 26.8 m/s at 34° to the x axis. What are the magnitude and direction of the force applied during this time?

I know that the electric and gravitational forces diminish wrt distance in accordance to the inverse square.

But what of dipoles? If you have an electric dipole, at what inverse power does the electric force diminish wrt distance? What about magnetic force?

Is it THEORETICALLY possible to actually = the speed of light

because I've read so many articles where physicists @ CERN accelerate particles to 99.999% of the speed of light, but never actually REACH it ...


If this were possible, what would it be like? Would your thoughts slow down completely as well ...would you be frozen for infinity ????

A toaster uses a Nichrome heating wire. When the toaster is turned on at 20°C, the initial current is 1.50 A. A few seconds later, the toaster warms up and the current has a value of 1.22 A. The average temperature coefficient of resistivity for Nichrome wire is 4.5 10-4 (C°)-1. What is the temperature of the heating wire?

~If possible, please explain in detail how you got the answer. Thanks.

An insulated beaker with negligible mass contains a mass of 0.345 kg of water at a temperature of 60.4 deg. Celsius.

How much ice at a temperature of -11.2deg. Celsius must be dropped in the water so that the final temperature of the system will be 20.2deg. Celsius?

Take the specific heat for water to be 4190 J/(kg*K), the specific heat for ice to be 2100 J/(kg* K), and the heat of fusion for water to be 334 kJ/kg.

Spontaneous generation is impossible in a macroscopic environment because of the 2nd law of thermodynamics. Fluctuation theorom, however, states that entropy can be decreased in a microscopic environment. Does that prove spontaneous generation (RNA world) are possible?
