Answer:
Option 1
Explanation:
The question is asking us what formula is used to obtain the quantity of heat added to a given mass of mercury in order to cause its temperature to change.
This quantity of heat is obtained from;
q = mcspΔT
Where;
q = quantity of heat added
m = mass of the mercury
csp= specific heat capacity of mercury
ΔT = temperature change
Answer:
protons: 36
neutrons:48
electrons:36
Explanation:
the number of protons in an element is = to the atomic # (36)
the number of neutrons is the atomic mass - atomic # (84-36=48)
In a neutral charged element the # of protons = # of electrons
Answer:
3-1-5-2-4
Explanation:
scientists believe that the solar system was formed when some star had its explosion and due to its explosion there were waves generated in the space thus squeezing clouds and dust eventually gravity pulling everything together forming solar nebula. the clouds spin faster and faster thus making it into a thin disk and also the cloud becoming hotter and dense thus forming stars.
