A helium4 atom has 2 protons and 2 neutrons. Its mass is 6.645 * 10^-27 kg. The mass of 4 hydrogen atoms is 6.693 * 10^-27 kg. Subtract the helium atoms mass from the 4 hydrogen and you get 0.048 * 10^-27 kg.

Answer:

All have binocular vision with fields of view that significantly overlap, resulting in true three dimensional (3-D) depth perception or stereoscopic vision. ... Depth perception is an invaluable tool for animals that need to move quickly. It allows them to judge the distances to important objects in their environment.

Cab someone please explain how I can balance this chemical equation?
julsineya [31]
You would add a 2 to every blank but 02 the reason why is 2 in the blank of h202 then makes that h404 while putting it in the other blank makes it h4 02 and add the other 02 then it makes it balanced. I’m pretty sure. It’s been a while since I did this in chemistry so don’t take my word for it but I’m pretty sure that’s how!

The graph of x^2=-2+y+5cosy is shown for y=11
erik [133]

(a)

We have been given an equation x^{2}=-2+y+5cosy. Upon taking derivative of this equation with respect to x on both the sides, we get:

2x=0+\frac{dy}{dx}+5(-siny)\frac{dy}{dx}\\2x=(1-5siny)\frac{dy}{dx}\Rightarrow \frac{dy}{dx}=\frac{2x}{1-5siny}

(b)

In order to write the equation of tangent line, we need to find the slope of the line. We know that point (3,11) lies on the graph. Therefore, we write the slope of the tangent as:

\text{Slope}=\frac{dy}{dx}=\frac{2(3)}{1-5sin(11)}=1

Therefore, equation of tangent line is:

y-y_{1}=m(x-x_{1})\Rightarrow y-11=1(x-3)\\y-11=x-3\\y=x+8

(c)

We know that slope of tangent is given as \frac{dy}{dx}=\frac{2x}{1-5siny}. The tangent will be vertical when denominator of slope is zero, that is:

1-5siny=0\Rightarrow siny=\frac{1}{5}\Rightarrow y=arcsin(\frac{1}{5})\\y=1.732,1.525, 3.063 \text{ etc.}
