Explain why sugar was used in this experiment. How does the experiment relate to a baker adding yeast to bread to make it rise?

Physics

Answer:

Yeast can use oxygen to release the energy from sugar (like you can) in the process called "respiration". ... So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point - even yeast cannot grow in very strong sugar - such as honey).

In an atom of hydrogen the orbit radius is given by the formula:
r = n² · α₀

where:
n = number of orbit = 15
α₀ = Bohr radius (innermost radius) = 0.529 Â

Since d = 2 · r, we can write:
d = n² · d₀
   = 15² · 1.06
   =  238.5 Â

Hence, the <span>diameter of the fifteenth orbit of the hydrogen atom is 238.5 </span>Â.

HURRY!!!!! Which change of state is shown into the model?
nadezda [96]

Option (B) is correct. The process shown in the model is the process of DEPOSITION.

Explanation:

The first container shows the molecules of the substance present inside it at a fairly large distance from one another whereas the second container, the molecules of the substance are very close to each other.

This shows that the substance in the first container is gaseous in nature whereas the substance in the second container is solid in nature as its molecules are closely packed.

Therefore, it shows the phase transition of a substance from gaseous sate to the solid state. The process of conversion of a gas directly into a solid is termed as deposition. This process is the opposite of the Sublimation in which the solid gets directly converted into a gas. Thus, the process is also termed as desublimation.

Thus, Option (B) is correct. The process shown in the model is the process of DEPOSITION.

Christopher drives into the city to buy new new hockey equipment. Because of traffic conditions, he averages only 15 mph. On the
alina1380 [7]

Answer:

36 minutes

Explanation:

Distance= Time*Speed

Let time taken to go to city be x hours, therefore, time to travel back is (2-x) hours

The distance to and from the city are equal hence

15x=35(2-x)

15x=70-35x

50x=70 hence x=70/50=1.4 hours

Time to drive home will be 2-x=2-1.4=0.6 hours

0.6*60=36 minutes

Therefore, time to travel back home is 36 minutes
