Explanation:
Higher the frequency smaller will be the wavelength. Higher frequency have shorter wavelength and lower frequency waves have larger wavelength. Also, Beats are formed by the superposition of two waves with slightly different frequencies but with similar amplitudes. In time, waves switch between constructive interference and disruptive interference, giving the resultant wave a time-varying amplitude.
The true statement about these two waves is option C. Wave A has a lower pitch.
Sound waves:
Sound waves when traveling via air are known as longitudinal waves .
Since sound passes via air, the particles of air does not vibrate in a transverse manner. Also, amplitude controls the loudness while on the other hand, frequency controlled the pitch. That means, the more frequent the higher should be the pitch.
Therefore, the correct option is C.

why would a pregnant mother need more calcium than a woman her age that is not pregnant?
Besides building teeth and bones, calcium also keeps your blood and muscles moving and helps your nerves send messages from your brain to the rest of your body. Your body can't make calcium, so you need to get it from food or supplements. While you're pregnant, try to get at least 1,000 mg of calcium every day.
Calcium is a vital mineral. Your body uses it to build strong bones and teeth. calcium is also needed for your heart and other muscles to function properly

How did boyle's change the way scientists make discoveries
Robert Boyle established chemistry as a discipline based on measurement, freeing it from the mysticism and alchemy that had plagued it. He introduced the concept of chemical analysis and defined elements, compounds, and mixes.
Boyle used a vacuum chamber to alter the gas's pressure in order to find the link between pressure and volume in a gas, which is now known as Boyle's law. In order to demonstrate that pressure and volume are inversely related to one another, he made detailed observations and carried out a number of experiments.
He developed a new vacuum pump and performed experiments in vacuum, they found that neither sound nor flame could exist there.

* i think i am right and i really hope so but please dont
count it against me babe.
explanation:
Individual hydrogen bonds are weak and easily broken; however, they occur in very large numbers in water and in organic polymers, creating a major force in combination. Hydrogen bonds are also responsible for zipping together the DNA double helix.
A hydrogen bond is formed when the positive end of one molecule is attracted to the negative end of another. The concept is similar to magnetic attraction where opposite poles attract. Hydrogen has one proton and one electron. This makes hydrogen an electrically positive atom because it has a deficiency of electrons.
A polar molecule is a chemical species in which the distribution of electrons between the covalently bonded atoms is not even. Some chemical species, such as chains of carbon molecules, share electrons equally and are said to be nonpolar molecules
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

A student did an investigation to determine the effect the amount of air would have on plant growth. She planted identical
plants in 4 separate closed containers with different volumes of air. She measured the height of the plants after they had
grown for 3 weeks.
What is the dependent (responding) variable in her investigation?
Answer:
Explanation:
The responding variable always is measured against the variable that you have control over.
In this case, you have control over the volume of air.
The responding variable is the amount the plant has grown. This would be a good long term experiment to try for a science fair or just because you might be interested. It's a good simple idea.
002 (part 1 of 2) 10.0 points For :393 g of butadiene (C,11,) calculate the number of moles. Answer in units of mol.
Answer:
7.27 mol C4H6
Explanation:
To calculate moles, divide the molar mass by the grams given
To find molar mass, add the atomic mass of the elements
12.011*4 + 1.008*6 = 54.092 g/mol
393 g * 1 mol/54.092 g = 7.265 mol

A geologist finds an area with a lot of slate, a type of metamorphic rock, on the surface of the land. What might this indicate about Earth's history in this area?
Answer:
Explanation:
Two things that can be deduced by this finding would be that the location was most likely a very muddy area with lots of clay minerals, as well as having lots of crustal movements. This is because slate is created when crustal movement buries clay minerals and other materials in the crust of the Earth. This is later melted and squeezed together from the sheer heat that is applied being so far underground. Therefore, creating what we now know as Slate.

what is photosysthies
Answer:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Explanation:
Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Explanation:
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants. Plants are also crucial to human life because we rely on them as a source of food for ourselves and for the animals that we eat.

Q+ ( poistive ion ) is an ion of element Q.
What has the highest value in the ion?
The proton number has the highest value in the ion
In an atomic element Q, the mass number is the number of the proton and the neutron, the electron encircles around the nucleus of the atomic element.
Recall that:
The electron is usually negatively charged;The neutron is a neutralThe proton is usually positively charged.∴
The atomic element Q+ has a positively charged ion, Thus, the proton number in the mass of the atomic element Q, therefore, has the highest value in the ion.
