Would it be more easy for a ball bearing to fall through a beaker of hot or cold honey
It would be more difficult for a ball bearing to fall through a beaker of hot honey than cold honey. This is because hot liquids are more viscous (thicker) than cold liquids, so the hot honey would provide more resistance to the ball bearing as it falls through.
What does temperature affect the viscosity of honey?Viscosity is a measure of a fluid's resistance to flow. Honey is a viscous liquid, which means it is thick and flows slowly. The viscosity of honey can be affected by temperature. As the temperature of honey increases, its viscosity decreases, which means it becomes thinner and flows more easily. Conversely, as the temperature of honey decreases, its viscosity increases, which means it becomes thicker and flows more slowly. So, hot honey is less viscous than cold honey.

Please answer my question.
Explanation:
Ionizable Amino Acids
Seven out of the twenty amino acids contain readily ionizable side chain groups. That means that at specific pH values, each side chain can participate in an acid-base reaction in which it can exchange a hydrogen atom with some other biomolecule. Since these side chains can form ions, that implies that they can also participate in forming ionic bonds. On top of these seven amino acids with ionizable side chains, all of the amino acids contain an ionizable alpha amino group and an alpha carboxyl group. The pKa value of each side chain group determines the pH value at which there will be equal concentrations of the acid and its conjugate base. The pKa value of the alpha amino group is 3.1 while the pKa value of the alpha amino group is 8.0. The pkA values of glutamic acid and aspartic acid are 4.1, the pKa of cysteine is 6.0, the pKa value of lysine is 8.3, the pKa value of lysine is 10.8, the pKa value of tyrosine is 10.9 and the pKa value of arginine is 12.5.
if an acid has a ka=1.6 x 10-10 what is the acidity of the solution
The information provided in the query is insufficient to calculate the solution's acidity. This is due to the fact that the equation pH = -log [H+] is the sole way to determine acidity.
What is the solution's acidity?A solution's acidity can be determined by looking at its pH, which is a measurement of hydrogen ion concentration. Pure water slightly separates into ions with roughly equal amounts of hydrogen & hydroxyl (OH) ions. [H+] is 107 for such a neutral solution, or pH = 7.

A cylinder and piston assembly (defined as the system) is warmed by an external flame. The contents of the cylinder expand, doing work on the surroundings by pushing the piston outward against the external pressure. If the system absorbs 586 J of heat and does 363 J of work during the expansion, what is the value of ΔE?
The value of ΔE is 223J when a cylinder and piston assembly (defined as the system) is warmed by an external flame.
The energy in the system must conserve according to the first law of thermodynamics:
ΔE = Q - W
In this equation, E stands for internal energy, Q for heat flow (which is positive if the system absorbs the heat and negative if it releases heat), and W for work (positive if the system is expanding, and negative if the system is compressing).
Q so equals +586 J, and W equals +363 J.

Shira is pushing a table toward Dominic with a force of 12 newtons (N). Dominic wants to stop the table from moving.
How much force will Dominic need to apply to stop the table from moving?
According to the Newton’s first law of motion, the force that Dominic needs to apply in order to stop the table from moving is 12 Newtons
Newton brought a further level of specificity to the aforementioned assertion by expressing the concept of force, which is a vector variable. His First Law states that an object that has a net force of zero operating on it will either remain at rest if it was initially at rest or it will maintain a constant velocity if it was initially moving at a constant speed. If the forces were balanced, then they would nullify one another and disappear. Because of this, the overall force is equal to zero.
To make zero net force, we can calculate it by:
Net force = Shira’s force + Dominic’s force
0 = 12 N + Dominic’s force
Dominic’s force = - 12 N or 12 N (opposite direction)
Hence, Dominic needs to apply 12N (opposite direction) to stop the table from moving.

Part A: The weight of a proton is given by the equation F=mg, where F is force, m is the mass of proton and g is the acceleration due to gravity. The mass of proton is 1.67 x 10^-27 kg. So F = 1.67 x 10^-27 kg x 9.8 m/s^2 = 1.63 x 10^-26 N. The strength of an electric field required to balance the weight of a proton is the force acting on the proton divided by the charge of proton, which is approximately 9.8 x 10^9 N/C.
Part B: The weight of a proton is an upward force and the electric field that will balance this force will also be upward.
Part C: Similarly, the weight of an electron is given by the equation F=mg, where F is force, m is the mass of electron and g is the acceleration due to gravity. The mass of an electron is 9.11 x 10^-31 kg. So F = 9.11 x 10^-31 kg x 9.8 m/s^2 = 8.89 x 10^-31 N. The strength of an electric field required to balance the weight of an electron is the force acting on the electron divided by the charge of electron, which is approximately 9.8 x 10^16 N/C.
electric fields we must take into account that the charge of the proton is positive and the charge of electron is negative.

a 5.00 g sample of water is heated so that its temperature increases from 10.0oc to 15.0oc. what is the total amount of energy absorbed by the water?
The amount of energy that the water has absorbed, according to the question, is 105 joules.
Where is the hottest spot on Earth?However, Mildrexler, who wasn't engaged in the current study, claims that the Lut Desert has truly arisen as the hottest site on Earth due to its "consistently hot imprint over a broad region."
Mass of water = 5 grams
Temperature change equals 10 ° from 15 degrees.
The formula for the amount of heat is as follows:
Q = m x c x Δθ
Where m =mass
c = specific heat capacity and
Δθ = change in temperature
c = 4.2J/g/degrees
Q = 5 x 4.2 x 5
Q = 105Joules

how many molecules of nadph are required for 12 molecules of rubp to be carboxylated by rubisco?
The six carbon compound formed when carbon dioxide and RuBP react immediately breaks down into two molecules of 3-phosphoglycerate, the Calvin cycle's first stable product.
What is carboxylation?Carboxylation is a chemical reaction that produces a carboxylic acid by exposing a substrate to carbon dioxide. Decarboxylation is the inverse reaction. Carbonylation (carboxylation) is the reaction in which an organic compound reacts with carbon monoxide, and carbonylation refers to reactions in which carbon monoxide is introduced into organic and inorganic compounds. Decarboxylation is a reaction in which carboxylic acids remove a carbon atom from a carbon chain. Carboxylation is a completely reversible process that occurs as the first chemical step in photosynthesis and involves the addition of CO2 to the compound.
