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.

Answer:

Gunshot residue is important to forensic scientists because it can help measure the firing distance of a weapon, or if someone has fired a weapon lately based on what's on their hands. The potential complications of this evidence include it being uncertain if the residue is from another firing. This type of evidence can also be uncertain in a courtroom when firing distance is drawn into question.

Answer:

Empirical formula is CH₃Cl.

Explanation:

Given data:

Percentage of hydrogen = 6%

Percentage of carbon = 24%

Percentage of chlorine= 70%

Empirical formula = ?

Solution:

Number of gram atoms of H = 6/ 1 = 6

Number of gram atoms of C = 24 /12=  2

Number of gram atoms of Cl = 70/ 35.45 = 2

Atomic ratio:

            C                      :      H            :         Cl

           2/2                    :     6/2           :       2/2

            1                       :        3          :        1

C : H : Cl = 1 : 3 : 1

Empirical formula is CH₃Cl.

Answer:

Electronegativities generally decrease from top to bottom within a group due to the larger atomic size.

Of the main group elements, fluorine has the highest electronegativity (EN= 4.0) and cesium the lowest (EN=0.79).

Explanation:

Sulfur has the largest electronegative element. Therefore, option C is correct.

Electronegativity is a measure of an atom's ability to attract electrons toward itself in a covalent bond, and it generally increases as you move across a period from left to right in the periodic table.

The type of bond that exists between atoms will depend on the electronegativity of the system.

Out of the given elements, S (sulfur) has the largest electronegativity. Sulfur has an electronegativity value of 2.58 on the Pauling scale, while Na (sodium) has an electronegativity value of 0.93, Mg (magnesium) has an electronegativity value of 1.31, and P (phosphorus) has an electronegativity value of 2.19. Therefore, option C is correct.

Answer:

Matter has mass and takes up space.

Explanation:

Matter is everything around you. Atoms and compounds are all made of very small parts of matter.

Mass is a measure of the amount of matter in an object.

Answer:

Normal force

Explanation:

normal force always perpendicularly points away from a surface

Normal force is the equal and opposite force for the Earth's force of gravity pulling down on the person as described by Newton's third law.

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

Answer:

λ = 0.032×10² m

Explanation:

Given data:

Frequency of broadcasts = 94.7 MHz

Wavelength of broadcasts = ?

Solution:

Frequency of broadcasts = 94.7× 10⁶ Hz

Formula:

Speed of wave = frequency × wavelength

3×10⁸ m/s = 94.7× 10⁶ Hz × λ

λ = 3×10⁸ m/s /94.7× 10⁶ Hz

 Hz = 1/s

λ = 0.032×10² m

Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.
