By locating the north celestial pole (ncp) in the sky, we can determine the latitude as the altitude of the NCP is the same as your latitude.
What is a latitude?A point on the surface of the Earth or another celestial body is given a latitude coordinate, which indicates its north-south location. Latitude is measured as an angle, with 0° at the Equator, and values ranging from -90° at the south pole to 90° at the north pole. A circle that runs parallel to the equator in both directions are lines of constant latitude, or parallels. An Earth surface location can be identified by its latitude and longitude when used as a pair of coordinates.
Typically, the word "latitude" used by itself refers to the geodetic latitude as described below. The angle created between the vector perpendicular (or normal) to the ellipsoidal surface from the point and the geodetic latitude of a point is, in a nutshell, what we refer to as latitude.

Find an equation of the normal line to the curve y = x that is parallel to the line 2x y = 1.
The equation of the normal line is y = - 2x + 3
We know that,
The equation of normal line given of the curve is given by
( y - [tex]y_{1}[/tex] ) = m ( x - [tex]x_{1}[/tex] )
Given that,
Equation of curve is y = [tex]\sqrt{x}[/tex]
Equation of the line parallel to the normal line of curve is 2x + y = 1
The slope of normal is same as that of the line parallel to it. So,
2x + y = 1
y = - 2x + 1
On differentiating both sides by x,
dy / dx = - 2
which is the slope of normal line
To find slope of the curve,
y = [tex]\sqrt{x}[/tex]
y = [tex]x^{1/2}[/tex]
dy / dx = 1/2 x
which is the slope of the curve.
Since the curve and its normal line is perpendicular,
[tex]m_{1} m_{2}[/tex] = -1
-2 * 1/2 x = -1
x = 1
At x = 1,
y = [tex]\sqrt{1}[/tex] = 1
The point is ( 1 , 1 )
The equation of normal line given of the curve is
( y - [tex]y_{1}[/tex] ) = m ( x - [tex]x_{1}[/tex] )
y - 1 = - 2 ( x - 1 )
y = - 2x + 3
Therefore, The equation of the normal line is y = - 2x + 3

What happens to most of the neutrinos produced by the nuclear reactions in the core of the sun? group of answer choices
The neutrinos produced by the nuclear reactions in the core of the sun escape from the sun into space.
The neutrinos produced by the nuclear reactions in the core of the sun is called solar neutrinos. These solar neutrinos are the decay product of nuclear fusion reaction in the sun.
These neutrinos then gets released into space which also reaches earth as light and heat.
Therefore, the neutrinos produced by the nuclear reactions in the core of the sun escape from the sun into space.

7. 122 10 292 252 Fig. 6.31 a The effective resistance of the circuit shown in the figure above is ? NE
R1+R2+R3 =1+1+1=3 is used to represent the circuit's overall resistance.
The 3 resistors on the upper side of the circuit are linked in series in this instance, and the total resistance R1 is expressed as 1+1+1=3.
The combined resistance R2 is expressed as 2+2+2=6 due to the series connection of the three 2-ohm resistors on the lower part of the circuit. The intermediate resistances R1, R2, and 2 are linked in parallel. This parallel connection's total resistance, R3, is therefore represented as 2/1+ 2/1+ 6/1 = 1/1=1 ohm.
In other words, the closed loop's resistance is decreased to 1 ohm.
Now, R1+R2+R3 =1+1+1=3 is used to represent the circuit's overall resistance (R).
As a result, the resistance in the circuit from point A to point B is 3.
