Who was Albert Einstien and what was he known for ?

Here ya go , Fivez and marcus UwU

Answers

Answer:

Albert Einstein is a German-born physicist and scientist who has created many ideas and theories relating to the study of relative. He is famously known for creating the famous equation [tex]e = mc^{2}[/tex] (Energy equals mass times the speed of light squared).

He was involved in the help of creating nuclear powered- mechanisms (not for destroying things, but for helpful, everyday things). Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously. Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation [tex]e = mc^{2}[/tex].

1)) The average depth of a lake is 10 meters. Do you think sunlight acts a limiting factor the same way it does in the ocean? Why or why not?

2)An area with a high population of crayfish in local lakes and rivers has begun experiencing acid rain, rain that has a pH of 3.0 - 4.0. Predict how this rain will impact the crayfish population.

Answers

Answer:

No.

Explanation:

No, the sunlight does not act as a limiting factor the same way it does in the ocean because the lake has lower depth as compared to ocean which is very deep i. e. more than 3000 meters where sunlight does not reach and we know that sunlight is very important for the survival of plants. Sunlight reach in the water about 1000 meters so plants can survive and do photosynthesis due to its low depth.

Acid rain will impact the crayfish population because acid rain decreases the pH of water and this lower pH causes death of the crayfish and also the food of crayfish and thus lower the population of crayfish due to unavailability of food..

Does the plant use all wavelengths of light to carry out photosynthesis? Why does this make plants look green?

Answers

Answer:

Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. ... All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.

After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react with oxygen (O2) in the air to produce rust (Fe2O3). a. Write a balanced equation for this reaction. Be sure to show your work.

Answers

Answer:

Explanation:

Oxygen gas and water must be present for iron to rust.

A region of the metal’s surface serves as the anode, where oxidation

occurs:

Fe(s) → Fe²⁺ (aq) + 2 e⁻

The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:

O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)

The overall redox reaction is:

2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)

The Fe²⁺ ions formed at the anode are further oxidized by oxygen:

4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)

This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.

In order to maintain homeostasis, the human body must be able to get rid of the waste products produced by cellular processes. The kidneys, for example, are responsible for removing waste from the bloodstream by producing urine.
