A car is accelerated at a rate of 2.5 meters/second?. If the starting speed is 5.0 meters/second, how
many seconds will it take the car to reach a final speed of 27.0 meters/second?
Answers
Answer:
8.8 seconds
Explanation:
Formula: acceleration = (v - u) /t where v = final velocity, u = initial velocity and t = time
a = 2.5 m/s²
u = 5.0
v = 27. 0
t =?
at = v - u
t = (v - u) /a
= (27- 5)/ 2.5
= 8.8 s
In order for a light bulb to be turned on in a circuit, it must have what kind of switch?
Answers
Answer:
Both switches must be closed in order for the circuit to be complete and for the bulb to light. (This would indicate the 'armed' status of this burglar alarm.) Magnetic switches come in 2 varieties - "Normally Closed" and "Normally Open". These 2 terms describe the state of the switch when it is NOT being controlled by the magnet.

Answer:
What is surface tension?
Explanation:
Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer.
Surface tension forces between mucosal surfaces play an important role in the pathogenesis of the disease. The obstruction of upper airway elicit the activation of autonomic nervous system, hypoxemia, and arousal from sleep.

✿❀❁❀✿What caused the channel on Mars? water or lava? give reasoning and evidence
Answers
Answer:
A channel in an ancient Martian "riverbed" wasn't carved by liquid water but was built by molten lava, according to a new study of surface features on Mars. ... On Earth, lava tubes form during sustained volcanic eruptions, when lava flowing through previously solidified masses leaves behind empty channels in the rock
Explanation:
The lava, itself (when liquid) is very much above the boiling point of water, so it is not wet with liquid water, so it's a no in that sense,' he writes. ... Lava does contain a lot of water, especially prior to eruption (when it's called magma), but also as it flows across the ground,' he explained.

A particular beer is 65.0% ethanol by volume . If a single bottle of beer contains a total of 750.0 mL of beer, what volume, in mL of ethanol (C₂H₆O), are present in the bottle?
SHOW CONVERSION
Answers
The volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5L
HOW TO CALCULATE VOLUME OF ETHANOL:
According to this question, a particular beer is 65.0% ethanol by volume. This means that the beer contains 65/100 of ethanol. If a single bottle of beer contains a total of 750.0 mL of beer, the volume of ethanol in the bottle is calculated as follows:= 65/100 × 750= 65 × 7.5= 487.5mLTherefore, volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5LLearn more at: https://brainly.com/question/8725232?referrer=searchResults
Which atom would you expect to have a larger atomic

Answers
Answer:
Francium bc it has the largest atomic radius
Francium has the greatest atomic radius. Despite being a highly radioactive metal with a short half-life, francium has little environmental impact.
What is francium?Francium is a chemical element with the atomic number 87 and the symbol Fr. Francium-223, its most stable isotope, has a half-life of only 22 minutes, making it extremely radioactive. It is the second-most electropositive element and the second-rarest naturally occurring element, trailing only caesium.Francium has been used to study atomic structure in addition to being used in chemistry and research. It is used in the diagnosis and treatment of cancer. It is also used in a number of spectroscopic experiments. Despite being a highly radioactive metal with a short half-life, francium has little environmental impact. Francium is created by bombarding radium with neutrons in a nuclear reactor. It is also possible to create it by bombarding thorium with protons.To learn more about francium refer to:

A saturated solution is one where there are equal numbers of particles, or solutes, and solvent in the solution.
Explanation:
The characteristics of a solvent are that it can be a liquid, a solid, or a gas; although the solvent is usually a liquid. When a solution cannot have solute added and dissolved, the solution is saturated.

A) the nuclei of each atom.
B) the protons in each atoms.
C) all electrons in the atoms.
D) the valence electrons in each atom.
Answers
Answer:
C
Explanation:
It depends on the bonding for an explanation.
If one atom is a metal and one is a non metal it will be ionic. This is because one atom transfers its electron to the other atom giving them both a charge. They will then be bonded due to opposite forces of attraction.
If both atoms are non metals it will be covalent. Electrons pair together in the center of two atoms that have merged together and they share their electrons.

Some chemicals, most often inorganic salts, in the laboratory have the nasty tendency to absorb water from the atmosphere. This property is called hygroscopicity. Anhydrous (water-free) Cupric Perchlorate [Cu (ClO4)2] weighs 262.447g/mol, but after sitting on out on the bench top absorbs water from the air and now weighs 370.540g/mol. How many water molecules did our Cupric Perchlorate absorb?
Answers
If an anhydrous Cupric Perchlorate weighs 262.447g/mol initially and weighs 370.540 g/mol after sitting on the bench to absorb water from the air, the number of water molecules absorbed would be 6 moles.
First, let us calculate the amount of water gained during the course of staying on the bench:
Water gained = weight after gaining water - initial weight
= 370.540 - 262.447
= 108.093g/mole
The total amount of water gained per mol is 108.093. Each water molecule weighs 18.015 g/mole. Thus, the total number of water molecules that will sum up to 108.093 would be:
108.093/18.015 = 6 moles
In other words, the number of water molecules absorbed by the Cupric Perchlorate is 6 moles.
