Yes, if my friend moved from Chicago to Buenos Aires, Argentina and said that she has observed constellations that cannot be seen in Chicago, because, two stars in same constellation may be actually very far away from each other.
What are constellations?Constellations are the groups of stars. The constellations you can see at night depend on your location on the Earth and the time of year. Constellations were named after objects, animals, & people long ago. Astronomers today still use the constellations to name stars and meteor showers. A constellation is group of stars that looks like a particular shape in the sky and has been given a name. These stars are far away from the Earth and they are not connected to each other at all. Some stars in a constellation might be close while others are very much far away. But, if you were to draw lines in the sky between the stars like a dot-to-dot puzzle – and use lots of imagination – picture would look like an object, animal, or person.
Why constellation is so important?constellation, in astronomy, any of certain groupings of stars that were imagined—at least by those who named them—to form conspicuous configurations of the objects or creatures in the sky. Constellations are useful in assisting the astronomers and navigators to locate certain stars.

back pushes with a force of 50 N. Which way
does the cart move?
The body would be moved in the forward direction by a net force of 10N.
What direction does the cart move?We know that force is a vector quantity. This implies that it has both magnitude and direction. The net force that acts on a body is the resultant force and this is the force that would move the object in a given direction. The object moves in the direction of the net force.
We are told that the forward force = 60 N
The backwards force = 50 N
We now have to determine the net force in order to understand the direction in which the body would move.

a. 3

c. 13
d. 16
The correct toption is (C) 13
The neutral atom of aluminum possess 13 protons.
Aluminum, denoted by the letter Al, is a group 3 element on the periodic chart. Total weight is 27 kilos. Since the number of electrons and protons in a neutral atom are equal, an aluminum atom that is neutral or uncharged has 13 electrons, 13 protons, and 14 neutrons. Keep in mind that the product of protons and electrons determines mass.The solution to this is that a 3+ charge on an aluminum ion means that an aluminum atom has lost three electrons, or 13 electrons - 3 electrons = 10. An aluminum atom will consequently have 10 electrons because it has a +3 charge. The fact that an aluminum atom possesses 13 protons when it is in a neutral state is unaffected by this.Learn more about the quantum mechanics with the help of the given link:

What is Autotransformer?An autotransformer is a type of electrical transformer that has just one winding. The word "auto" refers to a single coil that runs autonomously, not to a system that runs without human intervention. The primary winding and secondary winding sides of an autotransformer are distinct portions of the same winding. While there is no metallic conducting channel between the primary and secondary windings of a normal transformer, they are separate. The autotransformer winding has at least three taps that are utilized to connect electrical appliances. In terms of size, weight, and cost, autotransformers usually outperform conventional dual-winding transformers, but they also have the disadvantage of lacking electrical isolation between the primary and secondary circuits. Autotransformers also have advantages in terms of reduced leakage reactance, fewer losses, lower excitation current, and higher VA rating for a given size and mass.Learn more about the Autotransformer with the help of the given link:

As volume is held constant and the temperature increases, how would the pressure be expected to change?
Gay Lussac's Law states that when a gas is held at a fixed volume, its pressure is exactly proportional to its Kelvin temperature. The molecules of a gas receive more energy when heated, causing them to move more quickly. This results in increased pressure and more impacts on the container's walls.
What do you understand by pressure?Pressure is the term used to describe the physical force exerted on an object. A perpendicular force is applied to the surfaces of the objects per unit area. F/A is the fundamental formula for pressure (Force per unit area)
This is based on the supposition that the force is applied perpendicular to the surface area. The pressure would rise proportionately if you exerted the same amount of force over a larger surface area. 5 Pa would be the force of 5 N applied over the same area of 1 square meter.
