Two blocks of aluminum (specific heat c=0.22 cal/g Celsius) with masses of 1000 g and 100 g are at a temperature of 70 c. Which

block has more thermal (internal) energy? Explain why?
Physics

Internal thermal energy is given as

Q = mCT

so it will depend on the product of mass, specific heat capacity and temperature.

so here we know that both blocks are identical with same initial temperature

So the block with larger mass must have more internal energy

So here the correct answer would be the block with mass 1000g

block with mass 1000 g must have more internal energy

1. List one way mitosis and meiosis are the same and one way they are different.
kolbaska11 [484]
1. They both are same in the process, I mean they both are types of cell division they both form and give rise to new cells from the existing ones
difference would be in their division a mitotic cell gives rise to 2 cells where as a meiotic cell gives rise to 4.
2. the advantage of sexual reproduction is that , it produces genetic variation, disadvantage is it's a very slow process and takes lot of time
3. the advantage is that ,it's a very rapid process as it doesn't involve complex interactions. of genes and chromosomal recombination, the disadvantage would be is that they don't produce variation which can have adverse affect on their survival, even due to slightest change in the environment
4. Undergoing both the type of cell division is good as in human mitotic division is meant for growth and development whereas meiotic divisions are necessary and important for gametes formation and for raising new generation

Can someone please explain the quantum theory in simple terms
BaLLatris [955]
Quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level. The nature and behavior of matter and energy at that level is sometimes referred to as quantum physics and quantum mechanics.

The ratio of the speed of light in a medium to the speed of light in a vacuum
Liula [17]

Answer:D.Refractive Indez

Explanation:

It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
