Without stratospheric ozone, which of the following would most likely occur?
seraphim [82]

Answer:

III only

Explanation:

The ozone layer is extremely important for the living organisms on Earth. It is a layer that manages to stop big portion of the UV radiation from reaching the surface of the Earth, thus minimizing its negative effects, and only letting enough of it to be useful for the living organisms. If the ozone layer is removed though, then the UV radiation will be so high that most of the living organisms on land would die out because they can not stand such high levels of UV radiation. The marine organisms will also be badly effected, and the majority of them will also die out because of too much radiation, thus making enormous damage to the life on the planet.

Camila took an interest inventory in her career explorations class. Read her description of the results of the assessment. Which
densk [106]

Answer:

(3.) fascination with technology, I should work in a field with computers. Based on my (4.) attraction to working with mechanics, I should be working with machines.

Explanation:

The two phrases that clearly reveal Camila's career interests are 3 and 4 because they indicate what she likes and the career that she can follow according to that as they refer to her interest in technology and in working with machines which takes her to find that she can work in the robotics field.

The other options are not right because they talk about general interests that are not specific to a particular career.

For time t≥0 , the acceleration of an object moving in a straight line is given by a(t)=sin(t23). what is the net change in velo
Firlakuza [10]

The net change in velocity during the given time interval is equal to -0.665.

<u>Given the following data:</u>

  • Initial time = 0.75 seconds.
  • Final time = 2.25 seconds.
  • Acceleration, a(t) = sin(\frac{t^2}{3} )

<h3>How to calculate the net change in velocity.</h3>

Since acceleration is the rate of change of velocity of an object, we would derive an expression for the velocity by differentiating with respect to time:

V(t) = \frac{d}{dt} a(t)\\\\V(t) = \frac{d}{dt} (sin(\frac{t^2}{3} ))\\\\V(t) =  cos( \frac{t^2}{3})(\frac{2t}{3})\\\\V(t) = \frac{2t}{3}cos( \frac{t^2}{3})

Substituting the time interval, we have:

V(t) = \frac{2\times 2.25}{3}cos( \frac{2.25^2}{3})- \frac{2\times 0.75}{3}cos( \frac{0.75^2}{3})\\\\V(t) = \frac{4.5}{3}cos( \frac{5.0625}{3})- \frac{1.5}{3}cos( \frac{0.5625}{3})\\\\V(t) =1.5(-0.11643)-0.5(0.98247)

V(t) = -0.665.

What is the exact value of sin(105degrees)?
DochEvi [55]
Sin (105) = sin (15+90)= cos 15- ℎ ℎ

Explanation:
sin(105) = sin (60+45) because sin (a +b)= sin a • cos b+ cos a• sin b

Therefore,

sin 105= sin (60+45) = sin 60• cos 45 + cos 60 • sin 45 =

What are four things a new prince should do to maintain hold of his state?
pogonyaev

Answer:

The subjects of a conquered kingdom are not used to living in freedom or standing up for themselves, and are therefore slower to take up arms than are the citizens of a republic. There are three options for the conquering prince: destroy the republic, live there, or set up a puppet government. At the end of the day, Machiavelli seems to favor the first option.
