Answer:
These weather conditions are consistent with droughts, often characterized by hot, dry, weather. When this is the case, it is important to conserve water and use it only for necessities. Garden sprinklers are not essential, so their use can be sacrificed in order to provide more crucial services, such as drinking water. This rule has been put in place in order to avoid water shortages and energy crises, events that would be even more damaging during an emergency.
- 5. Venus is like Earth because A. They both have oceans, air, and plant life. B. They both have people living on them. C. They are about the same size and have about the same amount of gravity.
Answer:
C
Explanation:
Answer:
c
Explanation:
Venus and Earth are often called twins because they are similar in size, mass, density, composition and gravity. Venus is actually only a little bit smaller than our home planet, with a mass about 80% of Earth's.
why is extra vitamin C excreted in urine from the body but vitamin A in excess is retained in the body
Answer:
Vitamin C is water-soluble and not stored in your body
In contrast to fat-soluble vitamins, water-soluble vitamins do not get stored within the body. Instead, the vitamin C that you consume gets transported to your tissues via body fluids, and any extra gets excreted in urine ( 1 ).
Answer:
The reason vitamin C isn't stored well is because your body can't make it, and vitamin C is a water-soluble vitamin. This means it dissolves in water, and what your body doesn't use right away is excreted through urine. Thus, it is not stored in our body to a significant extent.

How many valence electrons does the following isotope have?
Answer:
I have solution to your question
Nitrogen is 7th element in periodic table. It contains 7 electrons in which are 2 are inner electrons and 5 are outer electrons. Here N is in -3 oxidation state. Thus, it is having 8 valence electrons.
What is an isotopes?Isotopes of are atoms with same atomic number and different mass numbers. Almost every elements have isotopes but some of them are unstable in nature.
Atoms forms ions when they lose or gain electrons. Wen they lose electrons, they form positive ions called cations. When they gain electrons they form negative ions or anions.
Nitrogen is 7th element in periodic table. It has 7 electrons out which 2 are inner electrons and 5 are valence electrons. N needs 3 more electrons to attain octet. Thus it gains 3 electrons and forms its 3 - oxidation state.
Thus N in -3 oxidation state have 8 valence electrons.

Answer:
Anser is C Agl
Explanation:
Agl does not dissolve in water.
All of the following compounds are soluble in water except AgI because of very high value of lattice energy. Therefore, the correct option is option C.
The capacity of a material, the solute, to combine with a different material, the solvent, is known as solubility in chemistry. Insolubility, or the solute's inability to create such a solution, is the opposite attribute. The concentration for the solute within a saturated solution—a solution where no more of the substance can be dissolved—is typically used to gauge the degree of a substance's solubility in a particular solvent. The two compounds are considered to be at the point of solubility equilibrium at this time. All of the following compounds are soluble in water except AgI because of very high value of lattice energy.
Therefore, the correct option is option C.

How many theoretical plates produce a chromatography peak eluting at 12.83 min with a width at half-height of 8.7 s
Darren looks up at night and sees a bright object with a tail moving quickly across the sky. What is the most likely object that Darren saw? A. an asteroid B. a meteor C. a comet . D. a cupid
Answer:
A
Explanation:
asteroids most often leave trails due to the large amount of friction that occurs.
The bright spatial object with a tail moving fastly across the sky is called a comet. Comets are made of rock, dust and ices.
What are comets?Comets are orbiting snowballs around sun made of frozen gases, rock, and dust. They enlarge to the size of a sizable town when frozen. A comet heats up and ejects dust and gases into a huge, blazing head that is larger than most planets when its orbit puts it near to the Sun.
Millions of kilometers away from the sun, the dust and gas combine to form a tail. The Kuiper Belt and much further Oort cloud are presumably home to billions of comets that orbit our sun.
Some of their ice begins to melt and boil off as the comet approaches the sun, along with some dust. The coma, which is created by these particles and gases, surrounds the nucleus.

4) If an object is traveling at a speed of 400 m/s, how long (in hours) will it take to reach 950.5 km?
A) 3.96 x 10-2
B) 1.43 x 105
C) 6.34
D) 39.6
E) 7.01 x 10-6
Answer:
Answer: 0.66 hours
Explanation:
[tex]{ \rm{time = \frac{distance}{speed} }} \\ \\ { \rm{time = \frac{(950.5 \times 1000) \: m}{400 \: m {s}^{ - 1} } }} \\ \\ { \rm{time = {2376.25 \: s}}}[/tex]
• Remember 1 second accounts for 1/3600 hours
[tex]{ \rm{time = \frac{2376.25}{3600} }} \\ \\ { \rm{time = 0.66 \: hours}}[/tex]
The time taken by object traveling at a speed of 400 m/s to reach 950.5 km distance is 0.66 hr or 39.6 min.
What is average velocity ?
Average velocity is given by the total distance covered by the object in total given time. SI unit of velocity is m/s.
Here in this question it is given that the object is travelling with speed v of 400 m/s and it is to find the time t to reach 950.5 km distance d.
it is known that 1 km = 1000 m
that is 950.5 km = 950500 m
Now, using the relation of speed-distance to find time t to reach 950.5 km distance :
[tex]\begin{aligned}v&=\frac{d}{t}\\t&=\frac{d}{v}\\&=\frac{950500}{400}\\&=2376.25 \text{ s}\end{aligned}[/tex]
Now converting 2376.25 sec into hrs by dividing it by 3600 we get :
2376.25/3600 = 0.66 hr or 39.6 min.
Therefore, the time taken by object to reach 950.5 km distance is 0.66 hr or 39.6 min.
