What does m c square mean?
mc2 could mean many things, but I assume you are talking about Einstein's famous equation E=mc2. I won't even pretend to know all the information behind this equation, but my understanding is that it basically calculates the amount of energy that could be spontaneously created by any mass. In the equation, E=mc2 E = Energy M = Mass C = Speed of Light (or 299,792,458 meters/second)
Is the word 'behind' an adverb?
No, it is a proposition.
The specific heat of lead is 128 kg degrees Celsius How much heat is needed to raise the temperature of a 0.015kg sample of lead by 10 degrees Celsius?
The relevant equation behind this problem is Q=m*c* ΔT Where Q is the energy that must be added to or taken from the system, m is the mass of the object, c is the objects specific heat, and ΔT is the change in temperature in Celsius or Kelvin. Plugging in the given values we get that Q=.015kg * 128J/(kg*C) * 10C=19.2J. Therefore, you need 19.2 joules of heat in order to raise the temperature of a .015kg sample of lead by 10 degrees Celsius.
What is the definition for butt?
A butt may be a barrel of wine, an archery target, the mound of dirt behind a rifle target range. a woodworking joint, a cigarette end, or to give a blow with the forehead.
Why calculus is important for computer scientist?
An understanding of the math behind the problem will help you solve the problem. High-level Computer Science is about modeling natural sciences which is where you will need to understand the basics of calculus.
