[tex]\huge\boxed{Buoyant Force}[/tex]
_____________________________________ARCHEMEDIS LAW (EUREKA)A body at rest in a fluid is acted upon by a force pushing upward called the buoyant force, which is equal to the weight of the fluid that the body displaces. If the body is completely submerged, the volume of fluid displaced is equal to the volume of the body. That is how we find the Volume of the Irregularly shaped objects.
_____________________________________FUN FACT:Archemedes the GREAT GREEK PHYSICIST was in a real problem finding out the formula of how to find the volume of irregular object. After countless failures in finding it, once he was going to get a apparently "BUBBLE BATH", So when he got into the tub the water displaced and got out from the tub resulting in the splash of water. His MIND CLICKED that we could find the volume by submerging the irregular object into the measured water and then substract the displaced water from it. He ran NAKED out of the house because of the happiness saying EUREKA! EUREKA! which literally means "I have found it". Thus this law of Archemedes is also called EUREKA LAW. So to simply remember how to find volume of irregular object keep EUREKA in mind.

Explanation:
The Law of Superposition allows us to determine:
a
which rock layers are the oldest
b
the relative age of layers of rocks and the fossils in them
c
the exact or absolute age of rock layers
d
a and b are correct
Answer:
d . a and b are correct
Explanation:
The law of superposition allows us to determine the age of rock layers and also that of the fossils within them.
The law of superposition states that "in an undeformed sequence of strata, the oldest rock layer is at the bottom and the youngest is on top".
Using this law, geochronologists can determine the relative ages of rock layers. The youngest layer will be found on top. The oldest at the bottom of the sequence. The arrangement of the layers and the fossils there in can also tell us about the ages of the fossils themselves.Melting chocolate (a change of state) is an example of a
1. You are pushing a heavy shopping cart full of water bottles with a constant force. The shopping cart has
mass of 250 kg and it is accelerating down the aisle at 0.20 m/s? How much force are you exerting?
Answer:
F = 50 N
Explanation:
Given data:
Mass of car = 250 Kg
Acceleration of car = 0.20 m/s²
Force required = ?
Solution:
Formula:
F = m×a
F = applied force
m = mass
a = acceleration
Now we will put the values in formula.
F = 250 Kg × 0.20 m/s²
F = 50 Kg.m/s²
Kg.m/s² = N
F = 50 N

How can you tell which elements form chemical bonds?
Answer: The number of bonds that an element can form is determined by the number of electrons in its valence shell. Similarly, the number of electrons in the valence shell also determines ion formation.
Explanation:
Using just the valence electrons on each atom determine which 2 atoms should be in the same group?
atoms 1 and 2
atoms 3 and 4
atoms 2 and 3
O atoms 1 and 4
Answer:
Explanation:
Atom 1 and 4 because they have the same number of valence elctrons in its outermost shell
How many electrons surround the
nucleus of an atom of Thallium?
Answer:
81
Explanation:
How much force is required to accelerate a 2 kg mass at 3 m/s²?
Answer:
6 N
Explanation:
Force (Newtons) = mass (kg) times acceleration (m/s2)
2 kg x 3m/s2 = 6 kg/m/s2

What is the frequency of a photon whose energy is 5.4 ´ 10-19 J? (h = 6.626 ´ 10-34 J·s)
Answer:
8.15 x 10¹⁴Hz
Explanation:
Given parameters:
Energy of photon = 5.4 x 10⁻¹⁹J
h = 6.626 x 10⁻³⁴J.s
Unknown:
Frequency of the photon = ?
Solution:
The energy of a photon is given as;
E = hf
h is the Planck's constant
f is the frequency
f = [tex]\frac{E}{h}[/tex] = [tex]\frac{5.4 x 10^{-19} }{6.626 x 10^{-34} }[/tex] = 8.15 x 10¹⁴Hz
3. What type of particles move to create electicity?
Electrical energy is caused by moving particles that have a negative or positive charge. These charged particles are called electrons. The faster the electrons are moving, the more electrical energy they carry. Electrical energy commonly moves through a wire in an electrical circuit.
[tex]\huge\boxed{Electrons.}[/tex]
_____________________________________Explanation...Electrons are particles that move to create electricity. In other words, they are responsible for electric currents. Thus, the answer should be Electrons.

What would happen if we couldn't carry respiration out?
Answer:
There would be no energy for cellular activities
Explanation:
Cellular respiration is the process whereby living organisms breakdown ingested food in their cells in order to obtain energy in form of ATP. In other words, respiration converts the stores energy in food molecules into usable energy by the cell. The general equation of the process is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
The process of cellular respiration is carried out by every living organism in order to obtain energy to perform their various metabolic activities. Hence, without RESPIRATION, there would be no energy (ATP) for use by the cell, which utterly means no cellular activities will take place.

Explain the three measures of retrieval and forgetting that Herman Ebbinghaus studied using nonsense syllables.
Answer:
There are three measures of retrieval and forgetting: recall, a measure in which an individual brings learned information back to conscious awareness; recognition, a measure in which a person identifies previously learned information; and relearning, a measure in which a person is asked to learn information a second time.
Explanation:
Answer:
Responses may vary but should include some or all of the following information:

2.911 grams of ethanol C2H5OH is burned and produces how many grams of water vapor?
Please help me or I'm dead.
Answer:
3.4g
Explanation:
Given parameters:
Mass of ethanol = 2.911g
Unknown:
Mass of water vapor = ?
Solution:
To solve this problem, let us write the balanced reaction equation first;
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
Now find the number of moles of ethanol;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of ethanol = 2(12) + 5(1) + 16 + 1 = 46g/mol
Number of moles = [tex]\frac{2.911}{46}[/tex] = 0.06mole
So;
1 mole of ethanol will produce 3 moles of water vapor
0.06mole of ethanol will produce 0.06 x 3 = 0.19moles of water vapor
Mass of water vapor = number of moles x molar mass
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Mass of water vapor = 0.19 x 18 = 3.4g
