The heat moves from the hot chocolate to the handle of the spoon by a process called thermal conduction.
It is the transfer of heat energy from one object to another when they are in contact with eachother.
Hope this answers your question.
Electromagnetic would be the weakest interaction of nature.
Answer:
200 million years
Explanation:
The equation that describes the decay of a radioactive isotope is
where
is the amount of radioactive isotope left at time t
is the initial amount of isotope
is the half-life of the sample
In this problem, the ratio between unstable isotope and daughter isotope is 1:15; this means that
Because the "total proportion" of original sample was 1+15=16.
Also we know that the half-life is
So we can re-arrange the equation to find t, the age of the rock:
So, 200 million years.
Transpiration is the evaporation of water from plants. This occurs when water drawn from the roots is brought up the leaves (as it usually should), and, because of the outside heat, it vaporizes and exits via the pores found on the underside of the leaves.
The answer is A because the oryx in the picture are competing.
