Answer:
Slower shutter speeds like 1/60 second and slower cause a blurring effect. If you want to take a picture using a slow shutter speed, it is best to mount the camera on a tripod and use image stabilization (such as SteadyShot® technology) to reduce the chance of any unwanted camera movement.
The first big effect of it is motion blur. If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. ... If you use an especially fast shutter speed, you can eliminate motion even from fast-moving objects, like birds in flight, or cars driving past.

The air in a syringe has volume 25.0 mL
when the pressure is 4.38 atm. What will be
its volume when the pressure is 0.65 atm?
Answer:
168.46 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
From the question we have
[tex]V_2 = \frac{25 \times 4.38}{0.65} = \frac{109.5}{0.65} \\ = 168.46153...[/tex]
We have the final answer as
168.46 mLHope this helps you
why is more dew formed on a grass and not on polished metal surface
Answer
Incidentally, they all form dew but because grass is closer to the soil, which maintains heat longer than the air where tree leaves are found, you will find more condensation in that region. Also, higher up the wind and sun will allow faster evaporation which makes the dew less noticable on tree leaves.
Explanation:
Preferred objects of dew formation are thus poor conducting or well isolated from the ground, and non-metallic, while shiny metal coated surfaces are poor infrared radiators. ... If the wet soil beneath is the major source of vapor, however (this type of dew formation is called distillation), wind always seems adverse.
True or False: In general, the farther a location is from the equator, the cooler the climate.
Answer: True
Explanation: The farther away from the center or heat.
Answer:
Yes
Explanation:
The equator is the imaginary belt around the earth and it is created and named because the sun mostly shines on that part/line making heat which causes it to be hot.
Which electron configuration shows an atom with 6 valence electrons?
Answer:
Valence electrons are the electrons in the outermost shell, or energy level, of an atom.example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.

Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen
on the graph?
Whenever the population has increased, steel consumption has increased as well
A larger population consumes greater amounts of fossil fuels like steel
When the population first started to increase, there was a need for much more construction
Steel consumption increased when people started to use computers.
Answer:
A. Whenever the population has increased, steel consumption has increased as well.
Explanation:
Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen on the graph is that whenever the population has increased, steel consumption has increased as well.
A critical look at the graph, you will discover that the population and the steel consumption are moving upwards (i.e they are increasing). It's seen that as the population increases, steel consumption increases. This is true because as the population increases, people are building houses, more transportation systems that require steel are being manufactured, more household utensils that are steel products are being fabricated etc; therefore the consumption of steel increases.

A student made the Lewis dot diagram of a compound as shown.
What is the error in the Lewis dot diagram?
A. The Ca atom should transfer only one electron to Ci because the formula is CaCi.
B. The number of dots around Ca should be one because Ca has to transfer only one electron to CI.
C. The Ca atom should transfer only one electron to CI, and the second electron should be transferred to another CI atom.
D. The CI atom should transfer two electrons to Ca because it has more electrons than Ca, so formula becomes CaCI*2
Answer:The Cl atom should transfer two electrons to Ca because it has more electrons
than Ca, so the formula becomes CaCl2.
Explanation: i took the quiz
Calcium forms ionic compound with two chlorine atoms as CaCl₂. Hence, Ca atom should transfer only one electron to one chlorine and the second electron is given to second Cl. Thus, option C is correct.
What is ionic bond?Ionic bond is formed between a metal and non metal by losing electron from the metal. The non metal should be an electronegative atom to accept that electron and forms a negative charge.
While the metal forms a partial positive charge. This charge separation make them attractive each other and make it ionic.
Ca is a second group element have two valence electrons. Ca forms compounds with halogens by donating its two electrons each to two halogen atoms and make a dihalide.
Cl have 7 electrons and tends to accept one electron from the metal to complete its octet. Thus one chlorine need only one electron from Ca. The second electron is then transferred to a second chlorine atom.
Therefore, the CaCl₂ compound is formed by transferring two electrons from calcium into two chlorine atom. Hence, option C ic correct.

Aqueous solutions of lithium hydroxide (LiOH) and acetic acid (HC2H3O2) will react to yield lithium acetate and water. In the balanced equation for this reaction, what is the lowest possible whole number coefficient for water?
Answer: The lowest possible whole number coefficient for water is 1.
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble water and remain in solid form are represented by (s) after their chemical formulas.
The balanced chemical reation for aqueous solutions of lithium hydroxide and acetic acid react to yield lithium acetate and water is:
[tex] LiOH(aq)+CH_3COOH(aq)\rightarrow CH_3COOLi(aq)+H_2O(l)[/tex]
Thus the lowest possible whole number coefficient for water is 1.
In the balanced equation for given reaction, the lowest possible whole number coefficient for water is one.
What is the stoichiometry?Stoichiometry of any reaction will tells about the relative amount of species presents before and after the chemical reaction.
Reaction between the lithium hydroxide and acetic acid is a neutralization reaction, as here lithium hydroxide is a base and acetic acid is a acid as a result of which it produces water molecule and lithium salt of acetate. And balanced equation for this will be represented as:
LiOH(aq) + CH₃COOH(aq) CH₃COOLi(aq) + H₂O(l)
In the above equation all entities are present in equal amounts on both the sides and from the stoichiometry of the reaction it is clear that coefficient of water is 1.
Hence, 1 is the whole number coefficient for water.

Answer:
0.0500L of 3.00M HCl are needed to react completely
Explanation:
Hydrochloric acid HCl reacts with sodium carbonate, Na2CO3, as follows:
2HCl + Na₂CO₃ → 2NaCl + H₂O + CO₂
Where 2 moles of HCl reacts per mole of Na₂CO₃
To find the volume of 3.00M HCl needed to react completely we need first to calculate the moles of Na₂CO₃ added and, with this chemical equation we can solve for moles of HCl as follows:

Why is it possible for an active metal like aluminum to be useful as a structural metal?
Answer:
Aluminum even after being an active metal is used as a structural metal due to its toughness, high strength, lightweight, and resistance to the process of corrosion. It is resistant to corrosion as its reactivity gets suppressed due to the formation of an aluminum oxide film which is protective in nature, on its surface. Passivation is the term for the formation of the protective coating.
