Explanation:
Answer:
Explanation: Rutherford model, also called Rutherford atomic model, nuclear atom, or planetary model of the atom, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford. The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun. Hope that helps!
Answer:
<h3>The answer is 1.04 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of coke = 21.36 g
volume = 20.5 mL
So we have
We have the final answer as
<h3>1.04 g/mL</h3>
Hope this helps you
Scientific notation is defined as writing a number between 0 to 10 multiplied by a power of 10
3.5 x 10² x 8.0 x 10⁻²
when we solve the equation
answer - 28
to write in scientific notation the decimal point should come after the first digit from the right. to bring the decimal point from after digit 8 to after digit 2, we have to move one decimal place to the left. then we get 2.8, to get the value as 28 we have to multiply 2.8 by 10
therefore answer is
2.8 x 10¹
1.) When a man is engaged to continuous exercise or work, not only his muscles are working but also there is increase in the rate of respiration too. This accelerated rate of respiration and heartbeat provides more oxygen and food to the body. So all the organs and organ systems work in coordination.
2.) I'm sorry that I don't know the answer to your question. The one which I know, I have already written.
