Which missing item would complete this beta decay reaction?
Flauer [41]
For us to understand the missing item that would complete beta decay reaction, we need to achieve in depth understanding of chemical formulas and nuclear symbols. Next is to have great comprehension of the following points:
<span>1.) Neutron in nucleus breaks down and changes into a proton.
2) Then it emits an electron, as well as an anti-neutrino which go into space.
3) Lastly, atomic number continuously goes UP while mass number remains unchanged.</span>

A telephone line hangs between two poles 14 m apart in the shape of the catenary , where and are measured in meters.
Masja [62]

Answer:

a) At x=14 the slope will be given by:

\frac{dy}{dx}(14)=a\sinh \left({\frac {14-C_{1}}{a}}\right).

b) Then, the angle between the line and the pole will be:

\phi=\pi - \theta

where \theta is the angle between the tangent to the catenary and the x-axis.

Explanation:

The catenary has the following general form:

y(x)==a\cosh \left({\frac {x-C_{1}}{a}}\right)+C_{2}

a) The slope at any point will be given by the derivative of y.

\frac{dy}{dx}(x)=a\sinh \left({\frac {x-C_{1}}{a}}\right)

At x=14:

\frac{dy}{dx}(14)=a\sinh \left({\frac {14-C_{1}}{a}}\right).

b) The angle between the tangent to the catenary and the x-axis at a given point will be given by:

\frac{dy}{dx}(x)=tan(\theta) ⇒ \theta=tan^{-1} (\frac{dy}{dx}(x))

Then, the angle between the line and the pole will be:

\phi=\pi - \theta.

A glass bottle of soda is sealed with a screw cap. The absolute pressure of the carbon dioxide inside the bottle is 1.50 x 105 P
MArishka [77]

Answer:

F \approx 19.5 N

Explanation:

From the question we are told that:

Pressure of  P_{CO_2}=1.50 * 105 Pa.

Bottle cap area A_b= 4.40 * 10-4 m^2

 

Generally the equation for Resultant pressure P_r is give as is mathematically given by

P_r=P_{CO_2}-P_a

Where

P_a=atmospheric\ pressure = 1.013*10^5 pa

P_r=1.50 * 105 Pa-1.013*10^5 pa

P_r=0.487*10^5 pa

Generally the equation for Force exerted by screw F is give as is mathematically given by

F = P*A\\F = 0.487*10^5*4.00*10^-4\\ F = 19.48 N

F \approx 19.5 N
