1. If the wavelength is changed, what will happen to the absorbance values?
S_A_V [24]

Answer:

The longer the path length, the more molecules there are in the path of the beam of radiation, therefore the absorbance goes up. As you likely know from other experiences, a particular chemical species absorbs some wavelengths of radiation and not others

The first five questions refer to the following problem:
MariettaO [177]

The Acceleration of a model rocket = 4 m/s²

<h3>Further explanation  </h3>

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  

∑F = m. a  

\large{\boxed{\bold{a=\frac{\sum F}{m}}}

F = force, N  

m = mass = kg  

a = acceleration due to gravity, m / s²  

An upward thrust of 35 N

A model rocket has a mass of 2.5 kg(weight = 25 N)

so resultant force :

\tt \sum F=F~upward~thrust-F~weight\\\\\sum F=35-25\\\\\sum F=10~N

The acceleration :

\tt a=\dfrac{\sum F}{m}\\\\a=\dfrac{10}{2.5}\\\\a=4~m/s^2

Animal Reproduction Interactivity
Leviafan [203]

<u>Step</u><u> </u><u>1</u>

Jellyfish do not give birth to their young because they expel undeveloped eggs in the form of zygote or embryo from their bodies and deposit them on the ocean floor before moving on. They don't even care about the eggs that have been laid.

<u>Step</u><u> </u><u>2</u>

Jellyfish have two distinct body types during their lives: medusa and polyps. Polyps reproduce by budding while medusa reproduce as by spawning eggs and sperm.

Jellyfish can reproduce in the adult, or medusa, stage by releasing sperm and eggs into the water, forming a planula. Polyps clone themselves and bud, or strobilate, into ephyra, a different stage of jellyfish life. The adult medusa jellyfish develops from his form.

Only a few jellyfish species obtain sperm through their mouths in order to fertilise eggs within their bodies, but the majority of jellyfish simply release sperm or eggs into the water. They will do this once a day, normally at dawn or dusk, if conditions are favorable.
