The plane's heading is 4.61 degrees south of east, which is the direction the pilot needs to steer the plane in order to reach her objective and the trip takes 1.83 hours.
<h3>What is the distance?</h3><h3 />
Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Let the pilot's heading be theta south with an east direction. The resultant the velocity will be;
![\rm 400 sin(\theta) - 50 sin(40) = 0 \\\\\ \rm 400 sin(\theta) - 37.25 = 0 \\\\ \ \theta= sin^{-1}\frac{37.25}{400}\\\\ \theta = 4.61^0](https://tex.z-dn.net/?f=%5Crm%20400%20%20sin%28%5Ctheta%29%20-%2050%20%20sin%2840%29%20%3D%200%20%5C%5C%5C%5C%5C%20%5Crm%20400%20%20sin%28%5Ctheta%29%20-%2037.25%20%3D%200%20%5C%5C%5C%5C%20%5C%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%5Ctheta%3D%20sin%5E%7B-1%7D%5Cfrac%7B37.25%7D%7B400%7D%5C%5C%5C%5C%20%5Ctheta%20%3D%204.61%5E0)
Hence the direction of the plane heading is 4.61 degrees south of east
b)
The resultant speed of the plane(V)is found as;
![\rm V= 400 cos(4.61) + 50 cos(40)\\\\ V = 437 miles/hr \\\\ T = \frac{800}{437}\\\\ T = 1.83 hour\](https://tex.z-dn.net/?f=%5Crm%20V%3D%20400%20%20cos%284.61%29%20%2B%2050%20%20cos%2840%29%5C%5C%5C%5C%20V%20%3D%20437%20miles%2Fhr%20%5C%5C%5C%5C%20T%20%3D%20%5Cfrac%7B800%7D%7B437%7D%5C%5C%5C%5C%20T%20%3D%201.83%20hour%5C)
Hence, the trip takes 1.83 hours.

Homogeneous - the mixture is even throughout the solution cannot tell one part from another
heterogenous - the mixture is not mixed even and you can tell one compound from another.
NaCl is a homogeneous solution since you cannot visibly separate the NaCl from the water it is dissolved in.

B cus is in the south but that pfp tho
This means that we shouldn't imagine electrons as single objects going around the atom. Instead, all we know is the probability of finding an electron at a particular location. What we end up with is something called an electron cloud. An electron cloud is an area of space in which an electron is likely to be found. It's like a 3-D graph showing the probability of finding the electron at each location in space. Quantum mechanics also tells us that a particle has certain numbers (called quantum numbers) that represent its properties. Just like how materials can be hard or soft, shiny or dull, particles have numbers to describe the properties. These include a particle's orbital quantum numbers, magnetic quantum number, and its spin. No two electrons in an atom can have exactly the same quantum numbers. Orbital quantum numbers tell you what energy level the electron is in. In the Bohr model, this represents how high the orbit is above the nucleus; higher orbits have more energy. The first orbit is n=1, the second is n=2, and so on. The magnetic quantum number is just a number that represents which direction the electron is pointing. The other important quantum mechanical property, called spin, is related to the fact that electrons come in pairs. In each pair, one electron spins one way (with a spin of one half), and the other electron spins the other way (with a spin of negative one half). Two electrons with the same spin cannot exist as a pair. This might seem kind of random, but it has effects in terms of how magnetic material is. Materials that have unpaired electrons are more likely to be magnetic
