Answer:
Process
Explanation:
Energy transfer is the process from one object to another object
Energy transfer is the transfer of energy from one object to another object.
Energy can be defined as the ability (capacity) to do work. Hence, the only standard unit of measurement of energy is Joules (J).
Generally, there are different forms of energy and these include;
Heat (thermal) energy.Light energy.Sound energy.Wind energy.Energy transfer is a process which refers to the transfer of energy from an object or physical body to another.
According to the Law of Conservation of Energy, energy can neither be created nor destroyed but it can only be converted (transformed) from one form to another such as kinetic energy to potential energy.
For example, a jug of hot tea has heat (thermal) energy, which is added to the particles in a cold powdered milk to make the coffee hotter.

A truck traveled at a constant speed for 6 hours. Then, it
decreased its speed by 13 mph for the remaining 228 miles. If
the total distance was 876 miles, how long did it take to travel
the remaining 228 miles?
h
Answer:
2.4 hrs
Explanation:
The constant speed of the truck for 6 hrs can be calculated by: speed=distance/time. Speed =(876-228)/6=648/6=108m/s. So the decreased speed = (108-13)=95m/h. Now, speed =distance /time We get 95m/h = 228/t. t=228/95 hrs = 2.4 hrs PLEASE MARK ME THE BRAINLIEST!!
Answer:
17.5 h

228/13=17.5384615385

help pls!!!!
Answer:
d
Explanation:
edge2020
Endocrine disruptors are commonly found in pesticides, plastics, and consumer products, and industrial by-products. Thus, the correct option for this question is D, i.e. all of the above.
What do you mean by Endocrine disruptors?Endocrine disruptors may be defined as a type of extrinsic substance or mixture that significantly changes the function of the endocrine system and subsequently stimulates adverse health effects in an intact organism, its offspring, or populations.
According to the context of this question, pesticides like DDT, Atrazine, etc. plastics, and food storage materials like bisphenol A (BPA), Phthalates, Phenol, etc., and industrial by-products Polychlorinated biphenyls (PCBs) and Dioxins causes the significant and effective disruptions of the endocrine system.
Endocrine disruptors are found in numerous everyday products, including plastic bottles and containers, liners of metal food cans, detergents, flame reductions, food, and pesticides.
Therefore, endocrine disruptors are commonly found in pesticides, plastics, and consumer products, and industrial by-products. Thus, the correct option for this question is D, i.e. all of the above.

In the past few decades, carbon dioxide levels have been rising.
In the past few decades, carbon dioxide levels have been falling.
A recent increase in carbon dioxide levels can contribute to a long-term cooling of Earth’s climate.
Answer: B - In the past few decades, Carbon dioxide levels has been rising because Rising levels of Carbon dioxide has become an immediate concern for the Environmentalists. This is because carbon dioxide is a greenhouse gas and risen levels of greenhouse gases can lead to unusual warming up of the Earth's Atmosphere.

What do ionic bonds form between?
Answer:
Ionic bonds form between cations and anions.
Explanation:
Electrovalent bonds (ionic bonds) form due to the electrostatic attraction between the two oppositely charged ions in the compound. A cation is formed when a metal ion loses a valence electron. Anions are formed the opposite way: a non-metal ion gains a valence electron.
Which of the following substances are soluble in water? Select all that apply.
a. NaCl
b. AgCl
c. AgNO3
d. KNO3
A, C and D are soluble in water.
What is solubility?Solubility is defined as the maximum amount of a substance that will dissolve in a given amount of solvent at a specified temperature.
Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.
AgCl is also not soluble in water because the forces favouring the formation of silver hydroxide (AgOH) are too weak to break the ionic bonds between silver and chlorine in AgCl. That means a bond between silver cation and the chloride ion is strong.
Silver nitrate is highly soluble in water but is poorly soluble in most organic solvents, except acetonitrile. It readily dissolves in water due to its strong ionic properties.
Potassium nitrate ([tex]KNO_3[/tex]) crystals were insoluble in water at room temperature. Heating the solution increases the solubility of the crystals in water.
Hence, A, C and D are soluble in water.

Write the balanced molecular equation for the acid-base reaction that occurs when aqueous solutions of hydrochloric acid (HCl) and sodium hydroxide (NaOH) are mixed.
Answer:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
Explanation:
Sodium hydroxide (NaOH) is a strong base and hydrochloric acid (HCl) is a strong acid. That means that they are totally dissociated into ions in aqueous solution.
When a solution of NaOH is mixed with a solution of HCl, a neutralization reaction occurs, in which a salt (NaCl) and water (H₂O) are formed.
The balanced molecular equation for this reaction is:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
