Acceleration is measured in _______ units.

Hello..!

There are 2 main types of ions one is an atom where the electrons are shared between the atoms. the other is an electron where one atom loses an electron to become a neutral in a charged ion, and the other atom gains the electron to become a charged lon anion.

\( \sf \red {\underline{ \underline{Explantation:}}}\)

Ions with a positive charge are known as cations. Those that are negatively charged are called anions.

¿Doubts? in the comments Greetings.

The two main types of bonds formed between atoms are ionic bonds and covalent bonds. An ionic bond is formed when one atom accepts or donates one or more of its valence electrons to another atom. A covalent bond is formed when atoms share valence electrons.

Answer:

Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its -------Potential --------- energy increases and its -----------kinetic----------------- decreases.

Explanation:

Kinetic energy is the energy of movement or change. Potential energy is the energy a system has as a result of being able to undergo some change. ... As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .

Explanation:

Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .

Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer:

sugar-water is a mixture not a compound.(homogeneous mixture.)

Explanation:

Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.

The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)

Answer:

4.77 × 10-7 meters

Explanation:

Energy of photon, E = hν  

Frequency of photon,

Thus, energy of photon,

Therefore, 4.165 × 10-19 joules =

λ =

λ =

λ  = 4.77 × 10-7 meters

The frequency of a photon having energy of 4.165 × 10-34 joules is 4.77 × 10-7 meters.

Answer:

"At eight pounds per gallon, that's another 38,593,169,564 pounds of water in the air. Add it all up, and the total weight of our sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds"

Explanation:

The total weight of our sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds. Sea level atmospheric pressure is 15 pounds per square inch, meaning every square inch of our planet’s surface has 15 pounds of air above it. One square inch is roughly one-third to one-half the size of an adult thumb.

That corresponds to 60,217,344,000 pounds of air for every square mile. Earth has a total surface area of 201,061,929 square miles. Do the math. Our atmosphere weighs 12,107,415,343,900,000,000 pounds.

According to meteorologists, water vapor averages 0.04% of the volume of Earth’s atmosphere. That means the sky holds 4,824,146,196 gallons of water.

At eight pounds per gallon, that’s another 38,593,169,564 pounds of water in the air. Add it all up, and the total weight of our sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds.

Answer:

The problem will be because:

The error in the construction of the bridge will be actually 40 cm.

Explanation:When you, as an engineer, listen about a scale 1/20, it means that for each 1 cm in the model, it will be 20 cm in the real footbridge (20 times upper to the scale model), then how the error in the model is 2 cm, the real error is 40 cm, in this case, imagine that you didn't know that the bridge will have an error of 40 cm, which is approximately 1,31 ft, from a side of the bridge you begin with the correct measure, and the other side you use the measure with the error of the 40 cm, the result is that when you going to finish the bridge in the center, this won't match, making more expenses to correct that big error.

Explanation:

Relative mass does not need to be calculated as it is listed on the periodic table. Potassium's relative atomic mass is around 39.

Answer:

It also helps them understand how life works. It even helps them predict how new materials will behave. In 1869, Dmitri Mendeleev, a Russian chemist, proposed the periodic law and his first periodic table. He published this periodic table two years later in a textbook, The Principles of Chemistry.

Explanation:

Answer:

Dmitri Mendeleev, To summarize, the periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered

Answer:

Hey,

So what you would do here is first choose a biome, such as the desert for example, then choose an organism that lives there, or an animal. Then think of what it is like where it lives, is it dry, cold, windy, and so force, just describing the place by its looks and climate. How would this population increase, maybe it would be if there was suddenly more food there for them, or if their ecosystem got better for them to live, then, if they populated more, how would that affect the ecosystem. Maybe some animals would die off more, or some would have to much food. Like what if the fly population suddenly doubled, for example, how would that affect the ecosystem? Now what would happen if that organism was removed? If flies were removed, spiders and a lot of other organisms would not have food, and some organisms would overpopulate because nothing would eat them. That is just an example.

I hope this helps, sorry if not. Have a great day!
