Shanika is an engineer at an amusement park who is experimenting with changes to the setup for a magnetic roller coaster ride. In one ride, there are two identical roller coaster cars (orange and green) that start on opposite sides of a large magnet located at the center of a station. Shanika wants to get the largest increase in potential energy she can by moving one car one space to the left or the right. Shanika can move the orange car to point A or point B, or she can move the green car to point C or point D. Which movement should she make? Why will that movement result in the largest increase in potential energy? Describe the magnetic force that will act on the roller coaster car she moves.

To determine the best movement for Shanika to make in order to achieve the largest increase in potential energy, let's analyze the scenario provided.

First, let's understand the concept of potential energy. Potential energy is the energy possessed by an object due to its position or condition. In this case, the potential energy of the roller coaster car is influenced by its location with respect to the magnet.

Now, let's evaluate the options Shanika has:

1. Moving the orange car to point A: If Shanika moves the orange car to point A, it will be closer to the magnet. This movement will result in an increase in potential energy because the car will be moving against the magnetic field.

2. Moving the orange car to point B: If Shanika moves the orange car to point B, it will be farther away from the magnet. This movement will lead to a decrease in potential energy because the car will be moving with the magnetic field.

3. Moving the green car to point C: If Shanika moves the green car to point C, it will be closer to the magnet. Similar to moving the orange car to point A, this movement will result in an increase in potential energy.

4. Moving the green car to point D: If Shanika moves the green car to point D, it will be farther away from the magnet. Just like moving the orange car to point B, this movement will lead to a decrease in potential energy.

Based on the analysis, Shanika should move the orange car to point A. This movement will provide the largest increase in potential energy. Moving the car against the magnetic field requires work to be done, thus increasing the potential energy of the system.

The magnetic force acting on the roller coaster car Shanika moves can be described as a force that opposes the motion of the car. When the orange car is moved closer to the magnet, the magnetic force will act in the opposite direction to the movement, resisting the car's motion and contributing to the increase in potential energy.

It is important to note that the analysis provided assumes that the strength of the magnetic field remains constant and that other factors, such as external forces or frictions, are negligible in this scenario.

Answer: 0.0045 mol
Explanation: Convert 30 ml to l: 30 mL = 0.03 L
Molarity = mol/l
mol = molarity * L
mol = 0.15 * 0.03 = 0.0045 mol

Answer: chalcogens.
Explanation: Strontium is an alkaline earth metal, it always exhibits a degree of oxidation in its compounds +2.
Chalcogens are a group of 6 chemical elements (oxygen O, sulfur S, selenium se, tellurium te, polonium Po) that have an oxidation state of -2 => Chalcogens will combine with strontium in a ratio of 1:1.

Answer:

A

Step-by-step explanation:

The input force is 50 N. But it will not create not any change. No mechanical advantage is observed.

Answer: b. Fiona is correct because the diagram shows two individual simple machines.

Explanation:
A mechanical device using which we can change the direction or magnitude of force applied is known as simple machine.
For example, in the given diagram there are two individual simple machines.
The machine helps in changing the direction or magnitude of force applied by the man. As a result, it becomes easy for him to carry different things easily from one place to another.
Thus, we can conclude that the statement Fiona is correct because the diagram shows two individual simple machines, is correct.

Answer:

52.6 gram

Step-by-step explanation:

It is clear by the equation 2(27+3×35.5)= 267 gm of AlCl3 reacts with 6× 80 = 480 gm of Br2 . So 29.2 gm reacts = 480× 29.2/267= 52.6 gm

15 moles.Explanation:Hello,In this case, the undergoing chemical reaction is:Clearly, since carbon and oxygen are in a 1:1 molar ratio, 15 moles of carbon will completely react with 15 moles of oxygen, therefore 15 moles of oxygen remain as leftovers. In such a way, since carbon and carbon dioxide are also in a 1:1 molar ratio, the theoretical yield of carbon dioxide is 15 moles based on the stoichiometry:Best regards.

Answer: 25 g
Explanation: Given:
Original amount (N₀) = 100 g
Number of half-lives (n) = 11460/5730 = 2
Amount remaining (N) = ?
N = 1/2ⁿ × N₀
N = 1/2^2 × 100
N = 0.25 × 100
N = 25 g

Answer: 7.8125 g
Explanation: Given:
Original amount (N₀) = 500 g
Number of half-lives (n) = 9612/1602 = 6
Amount remaining (N) = ?
N = 1/2ⁿ × N₀
N = 1/2^6 × 500
N = 0.015625 × 500
N = 7.8125 g
