Given theta = 7pi/6, find (sec theta, cos theta) ...?

Physics
1 answer:
uysha [10]3 years ago
5 0
There is an identity of sin(2pi-x) = -sin(x) and cos(2pi-x) = cos(x). This is what we are going to use. 


<span>(7pi/6) = (2pi)-(pi/6)

 </span>
Therefore: 
<span>
1) sec(7pi/6) = 1/cos(2pi-(pi/6)) = 1/cos(pi/6) = 2sqrt(3)/3 
</span>
<span>2) cos(7pi/6) = cos(pi/6) = sqrt(3)/2

A pulley system has an efficiency of 74.2%. If you perform 200 J of work, how much useful work does the pulley perform?
kirill115 [55]

<span>Efficiency is the measure of how efficient a process is. It is used to assess the ability of a process in avoiding waste energy, materials, money and time in doing a desirable output. It is calculated as;

Efficiency = useful energy ouput / total energy input</span>

<span>
.742 = useful energy / 200 J
Useful energy = 148.4 J  <-----------OPTION B</span>

These four surfaces are opaque; that is they reflect or absorb certain rays of light determine the color
masya89 [10]
In the first figure, the surface absorbs all colors except for green light, which is reflected: so, the surface will appear as green to our eyes, because green is the only color which is reflected by that surface.

Similarly, in the  second figure, the surface absorbs all colors except for blue, and so the surface will appear blue to our eyes.

In the third figure, the surface absorbs all colors, so it will appear black to our eyes (because no colors are reflected, and black=absence of colors).

In the fourth figure, all colors are reflected: this means the surface will appear white to our eyes (white= sum of all colors).
