C is the answer
Explanation:
Tidal cycles are affected by lunar day, semidiurnal and diurnal, lunar nodes, axial tilt ... Their tidal forces act to reinforce each other, and the ocean both rises higher and ... Tidal ranges - differences between neap tides and spring tides - graph ... The perigee of the moon can occur at any point in the orbit around the earth due ...
The correct option is option C among all the given options. This is because a spring tide occurs when the Moon and the Sun are aligned and pull on Earth.
What is tide?Any periodic deformation of one astronomical entity brought on by the gravitational pull of another is referred to as a tide. The most well-known are the regular fluctuations in Earth's sea level that are caused by shifts in the Sun's and Moon's relative locations. You can think of the tides as driven waves, flowing waves, and standing waves.
A tide with the largest difference between water levels at high and low tides is known as a spring tide. Two spring tides occur in each lunar cycle. This is because a spring tide occurs when the Moon and the Sun are aligned and pull on Earth. The Moon's ability to produce tides results from changes inside its gravitational field across Earth's surface in comparison to its strength at the planet's center.
Therefore, the correct option is option C among all the given options.

C. lower electronegativity
D. higher electron shielding
Answer:
C. Lower Electronegativity
Periodic table is divided into metals, non metals, semiconductors and noble gases on the basis of electron gain or loss. Metals have lower electronegativity. The correct options is option C.
What is metal?Metals are those elements which is hard, conduct electricity, ductile, lustrous and malleable.
Lets take properties
1.Since metals have free electrons that's why they can conduct electricity.
2. Since atoms in metals are very closely packed in a definite crystal so these are solid. Metals are not brittle that is, it can not be broken down easily
3.Metals do not react with water easily.
4.Metals are denser than water hence sink in water.

You go out to lunch one day and order a giant steak and a baked potato with sour cream. You ask for the nutritional information, and find out your lunch contains 51 g of carbohydrates (assume no fiber), 29 g of protein, and 40 g of fat. Does this lunch have a balanced energy ratio? If not, what macronutrient should be increased?
Answer:
This lunch does not yet have a balanced energy ratio. Carbohydrate ought to be increased to the stipulated 45 to 65 percent.
Explanation:
Total mass = 51 + 29 + 40 =120g
The percentage of calories from each is;
Carbohydrate - 51/120 * 100 = 42.5 %
Protein - 29/120 * 100 = 24.17 %
Fat - 40/120 * 100 = 33.33 %
According to the National Academy of Sciences, a balanced energy ratio for an adult diet should contain;
10 to 35 percent of calories from protein, 20 to 35 percent from fat, and 45 to 65 percent from carbohydrates.Hence this lunch does not yet have a balanced energy ratio. Carbohydrate ought to be increased to the stipulated 45 to 65 percent.

How many atoms are in 3.5 moles of carbon?
Answer:
Explanation: There are 5.418⋅1024 atoms in 3 moles of Carbon Dioxide. Explanation: 1 Mole is 6.02⋅1023 molecules. Therefore 3 Moles of Carbon ...
As in 1 mole there are 6.022 * 10^23 atoms.
So in 3.5 mole of carbon there are 21.077 * 10^23 atoms.
What do we should know about mole concept?
The mole concept is a convenient way to describe a substance's volume. The numerical magnitude and the units in which it is expressed are the two components of any measurement. When a ball's mass is measured to be 2 kilograms, for instance, the magnitude is "2" and the unit is "kilogram."Even one gram of a pure element contains a significant number of atoms when dealing with particles at the atomic (or molecular) level. The mole concept is frequently used in this context. It focuses primarily on the "mole" measurement, which represents a count of a very large number of particles.A mole is the amount of a substance that contains precisely 6.02214076 * 10^23 "elementary entities" of the given substance, as defined in the field of chemistry.Every substance has the same number of atoms or other particles in a mole. The mole and an element's mass are related in the following ways. There are 6.02214076 * 10^23 carbon-12 atoms in one mole, giving it a mass of 12 grams. By definition, one mole of oxygen has the same number of atoms as one mole of carbon-12, but it weighs 15.999 grams. As a result, oxygen has more mass than carbon. Weights of molecules or formulas can be accounted for using this logic as well.

What is food infection?Eating infected food can result in food poisoning, known colloquially as a foodborne sickness. At every stage of processing or manufacture, harmful organisms including bacteria and viruses may contaminate the food. If food is handled or prepared improperly, poisoning can also happen at home.
Food contamination can occur at any point during the planting, harvesting, or storage of raw materials as well as during cooking or other food preparation processes. Cross-contamination, or the movement of hazardous organisms through one surface to another, is another possibility. Metal shavings in canned corn can cause food infection.

5. A shopping mall wanted to determine whether the more expensive
"Tough Stuff" floor wax was better than the cheaper "Steel Seal" floor wax
at protecting its floor tiles against scratches. One liter of each brand of
floor wax was applied to test sections of the main hall of the mall. The test
sections were all the same size and were covered with the same kind of
tiles. After 3 weeks, the number of scratches in each of the test sections
was counted to observe the wax's effectiveness. Identify Control Group
Answer:
Control group:
Test section covered with the "Steel Seal" floor wax
Explanation:
In a scientific experiment, the control group is the standard group to which comparison is made, to determine the effect of the experimental agent on the test subjects. In this example, the Steal Seal floor wax is the standard wax being used, and the experimenter wants to see if the "Tough Stuff" wax is better, hence after the treatment with the Tough Stuff wax, the number of scratches observed is compared with the standard wax area and the difference determines if it is a better waxing agent or not.

Which statement about the atomic nucleus is correct? a. The nucleus is made of protons and neutrons and has a negative charge. b. The nucleus is made of protons and neutrons and has a positive charge. c. The nucleus is made of electrons and has a positive charge. d. The nucleus is made of electrons and has a negative charge. Please select the best answer from the choices provided A B C D
Answer:
The answer is B
Explanation:
The nucleus of an atom is made up of neutrons and protons since neutrons are neutral and hold no charge while proton hold a positive charge so overall nucleus is positively charged.
The nucleus of the atom has been consisted of neutral neutrons and positive protons. The nucleus has been positively charged. Thus, option B is correct.
The atoms have been the smallest unit of matter. The determination of the structure of atoms has been revealed with several studies.
The atoms have been found to be consist of electrons, protons, and neutrons as subatomic particles. The electrons have been the lightest unit of the atom having negligible mass.
The electrons have been the negatively charged bodies revolving around the nucleus. The central part of the atom has been the nucleus consisting of neutrons and protons.
The neutrons are the neutral atoms, while protons are the positively charged atoms. Thus, the nucleus has been the positively charged entity of the atom. Thus, option B is correct.
