Which of the following statements is correct regarding the speed and velocity of an object? A. An object’s speed is determined by the distance the object traveled and how long it took the object to travel that distance. B. An object’s velocity is determined by the distance the object traveled, how long it took the object to travel that distance and what acceleration the object traveled. C. An object’s velocity is determined by the distance the object traveled and how long it took the object to travel that distance. D. An object’s speed is determined by the distance the object traveled, how long it took the object to travel that distance and what direction the object traveled.
Answer:
Explanation:
D
An object’s speed is determined by the distance the object traveled, how long it took the object to travel that distance, and what direction the object traveled. This statement is correct regarding the speed and velocity of an object.
What is velocity ?The directional speed of an item in motion, as measured by a specific unit of time and viewed from a certain point of reference, is what is referred to as velocity.
Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route.
Constant acceleration and constant velocity are both forms of motion, as you have already read. Because acceleration is the rate at which velocity changes, constant velocity and constant acceleration go hand in hand.
Thus, option D is correct.

which molecules are required for the citric acid cycle to fully oxidize the carbons donated by acetyl coa?
Explanation:
At the start of the citric acid cycle, a molecule of oxaloacetate accepts a two-carbon acetyl group from acetyl CoA to form citrate. This reaction kicks off the citric acid cycle; thus, oxaloacetate is required for the cycle to take place.
To begin the citric acid cycle, an oxaloacetate molecule accepts a two-carbon acetyl group from acetyl CoA to form citrate. Because this reaction initiates the citric acid cycle, oxaloacetate is required for the cycle to occur.
What is citric acid cycle ?The Krebs cycle, also known as the citric acid cycle or TCA cycle, is a chain of reactions that occurs in the mitochondria and is used by almost all living cells to produce energy through aerobic respiration. It consumes oxygen and emits water and carbon dioxide as byproducts.
All aerobic organisms use a series of chemical reactions to generate energy by converting acetate derived from carbohydrates, fats, and proteins into carbon dioxide.
The citric acid cycle involves the attachment of an acetyl group from acetyl CoA to a four-carbon oxaloacetate molecule to form a six-carbon citrate molecule.
Thus, Citrate is oxidized in a series of steps, releasing two carbon dioxide molecules for each acetyl group fed into the cycle.

for the sn1 reaction, draw the major organic product, identify the nucleophile, substrate, and leaving group, and determine the rate limiting step.
C4H9OH is the substrate, Br- is the nucleophile and H2O is the leaving group.
In an SN1 reaction, the rate limiting step is the formation of the carbocation. The carbocation is formed as water which is the leaving group departs. After the leaving group departs, the nucleophile (Br-) attacks to yield the major organic product. The protonation of the -OH group is the first step in the reaction.
It then follows that, C4H9OH is the substrate, Br- is the nucleophile and H2O is the leaving group.

21. When considering the Bohr model of a neon atom, which of the following is a true statement?
Ten protons would be located in the nucleus, and 10 neutrons would be on the outside of the atom orbiting in rings.
Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
O Ten protons would be located in the nucleus, and 20 neutrons would be on the outside of the atom orbiting in rings.
OTwenty protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
The characteristics of the Bohr model allow you to find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.
The bohr model was initially developed for hydrogen, where it manages to fully explain the spectrum of the hydrogen atom, it was quickly spread to other multi-electronic atoms with the characteristic of having a single electron in their last orbit.
The extension to atoms with more than one electron in the last shell the model results are not completely correct.
The Bohr model uses Rutherford's knowledge that the atomic nucleus is a very small part of an atom that contains all its mass, that is, it contains the protons and neutrons and the electrons are in circular orbits around the nucleus.
In the case presented of Neon, its electronic configuration is
1s² 2s² 2p⁶
Let's examine the different claims:
a) False. Protons and neutrons form the mass of the atom, therefore they are both in the nucleus.
b) True. The protons are in the nucleus and the electrons are in circular orbits.
c) False. All protons and neutrons must be in the nucleus, plus neon only has 10 neutrons.
c) False. The number of protons determines the type of atom. An atom with twenty protons is Calcium atom .
In conclusion, using the characteristics of the Bohr model we can find that the correct answer for the distribution of particles in the atom is:
b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.

Which statement correctly compares ice and liquid water?
A. Both liquid water and ice have definite shapes.
B. Particles of liquid water have more energy than particles of ice.
C. Liquid water has a lower temperature than ice.
D. Ice has a definite volume, but liquid water does not.
Answer:
B. Particles of liquid water have more energy than particles of ice.
Explanation:
We can work this out through eliminating the wrong statements.
A. Both liquid water and ice have definite shapes.
This is wrong because, as stated in the question, water is a liquid, and one of the properties of liquids is that they change shape to fit the shape of their container. If it changes shape, it does not have a "definite" shape.
B. Particles of liquid water have more energy than particles of ice.
This is correct, and here is why. There are 3 states of matter: solid, liquid and gas. As you apply heat energy to an object at each state, the particles receive more energy and can move around more (this is kinetic energy). In the case of liquid (water) and solid (ice), particles in solids do not have much energy and stay in rigid formations. They do vibrate slightly, but only on the spot (this is what gives solids "definite" shapes). On the other hand, particles in liquids have more energy than particles in solids, which means that they can move more (more kinetic ENERGY) and do not stay in formations (this is why they do not have "definite" shapes). Therefore, particles in liquids (water) have more energy than particles in solids (ice), and this statement is correct.
C. Liquid water has a lower temperature than ice.
This is wrong because liquids have more energy than solids. As explained earlier, the reason why particles in liquids have more energy is because more HEAT energy has been applied to them. In the same way, solids have less energy because less HEAT energy has been applied to them. Less heat means a lower temperature. (Also you can use common sense for this one, ice feels colder than liquid water, right?)
D. Ice has a definite volume, but liquid water does not.
This is wrong because of the law of conservation of mass. This law states that particles (or matter or volume) cannot be created or destroyed. When ice melts and becomes liquid water, it has not lost volume: the particles have just gained more energy. This question is most likely there to confuse you, because all substances have definite volumes.
