Give a reason why it might be important to know Newton’s second law in the real world.
Answer:
Newton's Second Law states that an object's acceleration depends on the net force upon the object, as well as the object's mass.
So, a real world example of this would be pushing a vehicle out of a ditch. If your vehicle is a motorcycle, with a relatively small mass, then you don't need to apply much force on it, as compared to if the vehicle were a pickup truck, with a large mass, which would require much more force applied to move it out of the ditch.
I hope this helps! Feel free to give me Brainliest if you feel this helped. :)

What best explains why the moon's surface gravity is only one-sixth of Earth's surface gravity?
A) Earth is closer to the Sun, so it has much more gravity.
B) Gravity is controlled by the tides, which are much closer to Earth than the moon.
C) The moon orbits Earth faster than Earth orbits the Sun, giving the moon less gravity.
D) Gravity is the result of an object's mass and size; the Earth is much larger than the moon.
Answer:
D) part is the correct answer
Answer:The answer is D
Explanation:The moon is a bit more than one-fourth (27 percent) the size of Earth, a much larger ratio (1:4) than any other planets and their moons. Earth's moon is the fifth largest moon in the solar system. The moon's mean radius is 1,079.6 miles (1,737.5 kilometers).
Match the correct type of energy transfer that takes place.
Answer:
Lightbulb: electrical energy to light energy
Alarm Clock: electrical energy to sound energy
Rollercoaster: electrical energy to mechanical energy
Riding a Bike: chemical energy to mechanical energy
Explanation:
Light bulbs, alarm clocks, and roller coasters require electrical energy to work. This energy then changes into the subsequent types. Light bulbs primarily emit that energy in the form of light, alarm clocks change that energy into sound, and roller coasters begin to move (mechanical). People power bikes, and the energy in our body is stored as chemical energy. So, when we rides bikes, that energy gets turned into moving (mechanical) energy.

Answer:
Aluminum
Explanation:
Ferromagnetic Metals
Ferromagnetic metals and alloys are the only magnetic metals. Out of all of the elements on the periodic table, there are only 3 metals that are attracted to magnets: iron, nickel, cobalt.
Aluminum
Aluminum is a nonferrous metal (meaning not including iron or steel) that does not include any ferromagnetic metals. Additionally, aluminum itself is not magnetic, so there is no attraction between aluminum and a magnet.

18 sep analyze and interpret data the table shows several ionic solids, their average
bond energies in electron volts (ev), and their melting points. use the pattern
indicated in the table to predict the average bond energy of calcium fluoride (caf2
), which has a melting point of 1420°c.
The bond energy is the energy that must be supplied to break the bond. Ionic substances are held together by strong bonds.
What is bond energy?This question is incomplete but I will try to explain what is meant by average bond energy as the tables are missing.
The average bond energy of a bond simply means the energy that is stored in that bond as it holds two atoms together. It is equal to the energy that must be supplied to break the bond. The numerical value of the bond energy can not be deduced as the data is missing.

HNO3(aq)+H2S(s)> Ss)+ NO(g)+H2O(l)
Answer: Nitric acid + Hydrogen disulfide
Explanation: To balance HNO3 + H2S = NO + S + H2O you'll need to be sure to count all of atoms on each side of the chemical equation.
Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Nitric acid + Hydrogen disulfide .
Important tips for balancing chemical equations:
Only change the numbers in front of compounds (the coefficients).
Never change the numbers after atoms (the subscripts).
The number of each atom on both sides of the equation must be the same for the equation to be balanced.

An atom can be called a particle, but a molecule is never called a particle.
Answer:
Atoms are composed of particles called protons, electrons and neutrons. ... A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. Protons and neutrons are both composed of other particles called quarks and gluons.
Particles can be atoms, molecules or ions. The term molecule is often used incorrectly to refer to any type of chemical compound. A molecule is a neutral particle made of two or more atoms bonded together. Take care with your own language, especially when referring to compounds formed during chemical reactions.

A gas at STP occupies 16 L of space. If the pressure changes to 2.6 atm and the temperature increases to 195 degrees C, what is the new volume? Show your work.
I WILL MARK YOU BRAINLIEST! PLEASE HELP!
The new volume of a gas at STP that occupies 16L of space is 27.43L.
HOW TO CALCULATE VOLUME?The volume of a given gas can be calculated using the following expression:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressureP2 = final pressureV1 = initial volumeV2 = final volumeT1 = initial temperatureT2 = final temperature1 × 16/273 = 2.6 × V2/468
16/273 = 2.6V2/468
0.0586 × 468 = 2.6V2
V2 = 27.43
Therefore, the new volume of a gas at STP that occupies 16L of space is 27.43L.

CrO42-+2H+=Cr2O7^2-+H2O
A student add sodium hydroxide (NaOH) to the solution equilibrium. In 1 to 2 sentences describe and explain any changes to the solution that the student will observe.
Addition of NaOH will cause the equilibrium position to move to the left because of the removal of the hydrogen ions.
Equilibrium position
When changes in temperature, pressure or concentration is imposed on a reaction system in equilibrium, the system will readjust itself in order to annul the change.
This change occur when the equilibrium position is moved to the left or right. For the reaction, CrO4^2-+ 2H^+ ⇄ Cr2O7^2- + H2O, addition of NaOH will cause the equilibrium position to move to the left because of the removal of the hydrogen ions.

Is there a different way to balance a synthesis, decomposition, single displacement and double displacement reactions or is it all the same
Answer:
This is the reverse of a synthesis reaction. Replacement reactions occur when elements switch places in compounds. In a single replacement reaction, one element takes the place of another in a single compound. In a double replacement reaction, two compounds exchange elements
