Below are the choices:

<span>It felt hot in the science lab, and my skin felt sticky. I ran the experiment by spinning the sling psychrometer. There was a very small difference in the dry bulb and wet bulb temperatures. This is the result of the water on the wick of the wet bulb evaporating rapidly. The evaporation caused a slight drop in the level of mercury in the wet bulb. I conclude that the relative humidity in the lab is very high.

I think the answer should be  The evaporation caused a slight drop in the level of mercury in the wet bulb.

What is the universe’s eventual fate
laila [671]

Explanation:

The eventual fate for our open universe is believed to be either universal heat death, the "Big Freeze", or what can be considered the "Big Rip". This is where the acceleration caused by dark energy eventually becomes so strong that it completely overwhelmes the gravitational, eltromagetic and our strong binding forces.

Suppose 0 is an angle in the standard position whose terminal side is in Quadrant IV and cot0= -6/7 Find the exact values of the
Sergio039 [100]
<h2>\sin \theta=\dfrac{p}{h} =\dfrac{-7}{\sqrt{85} }, \cos \theta=\dfrac{b}{h} =\dfrac{6}{\sqrt{85}}, \tan \theta=\dfrac{p}{b} =\dfrac{-7}{6},</h2><h2>\sec \theta=\dfrac{h}{b} =\dfrac{\sqrt{85} }{6} and \csc \theta=\dfrac{h}{p} =\dfrac{-\sqrt{85}}{ 7}</h2>

Explanation:

Given,

\cot \theta= \dfrac{-6}{7}

To find, the exact values of the five remaining trigonometric functions of \theta = ?

We know that,

\cot \theta= \dfrac{-6}{7}=\dfrac{b}{p}

Where, b = base and p = perpendicular

By Pythagoras's theorem,

Hypotaneous, h=\sqrt{p^2+b^2}

=\sqrt{(-6)^2+7^2}=\sqrt{36+49} =\sqrt{85}

In IVth quadrant,

\cot \theta and \sec \theta are positive.

\sin \theta=\dfrac{p}{h} =\dfrac{-7}{\sqrt{85} }, \cos \theta=\dfrac{b}{h} =\dfrac{6}{\sqrt{85}}, \tan \theta=\dfrac{p}{b} =\dfrac{-7}{6},

\sec \theta=\dfrac{h}{b} =\dfrac{\sqrt{85} }{6} and \csc \theta=\dfrac{h}{p} =\dfrac{-\sqrt{85}}{ 7}
