Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.
hope it helps ☺️✌️
Answer:
over years of being underground the pressure causes the organism to press into the rock and form a mold. this mold is the fossil and are found in sedimentary rock

How do catalysts and inhibitors affect reaction rates
Please I'm in desperate help
Answer:
You know that catalysts lower the activation energy required for a reaction to occur. With the activation energy lower, the products can also combine more easily. Therefore, the forward and reverse reactions are both accelerated. It changes both rates and usually changes the equilibrium point.

A charged particle of 5.1 nC and another with 2.6 nC are separated by a distance of 5.5 m. What is the electric potential energy between the particles?
Answer:
The electric potential energy between the particles is 2.167 x 10⁻⁸ J
Explanation:
Given;
a charged particle, q₁ = 5.1 nC
another charged particle, q₂ = 2.6 nC
distance between the charged particle, r = 5.5 m
The electric potential energy between the charged particles is calculated as;
[tex]U_E = \frac{kq_1q_2}{r}[/tex]
where;
[tex]U_E[/tex] is the electric potential energy between the particles
k is coulomb's constant = 8.99 x 10⁹ Nm²/c²
Substitute the given values and solve for electric potential energy;
[tex]U_E = \frac{kq_1q_2}{r} = \frac{8.99*10^{9}*5.1*10^{-9}*2.6*10^{-9}}{5.5} \\\\U_E = 2.167 *10^{-8} \ J[/tex]
Therefore, the electric potential energy between the particles is 2.167 x 10⁻⁸ J
Which of the following particle is responsible for the transfer of static charge?
A. Neutron

D. A & C
Answer:
B. Electron
Static charge is produced by electron transfer.
Explanation:
Answer A: The neutron does not possess a charge and is said to be neutral.
Answer D: Protons and neutrons never move from object to object.

Background information on thermal energy transfer and conservation of energy
Answer:
Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation. ... Convection transfers thermal energy through the movement of fluids or gases in circulation cells.Convection. When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises.

What are the three types of sea ice and why is each important?
Answer: New Ice, Nilas, and young ice.
Explanation:
New ice is recently frozen sea water that does not yet make up solid ice.
Nilas is an ice that bends without breaking around waves and swells.
Young ice is a transition stage between nilas and first-year ice.
En un proceso isobárico, la presión del gas es de 105 Pa. Halle el desplazamiento del pistón, cuya área es de 0,4 m2, cuando el gas desarrolla un trabajo de 8 x 104 J
Answer:
The displacement of the piston is 1904.76 m
Explanation:
Here we have an isobaric or constant pressure process, therefore;
Work done, W = P × (V₂ - V₁)
Where:
W = 8 × 10⁴ J
P = Pressure of the gas = 105 Pa
V₁ = Initial volume of the cylinder of the piston
V₂ = Final volume of the cylinder of the piston
We note that volume of the cylinder of the piston = Base area, A × h
Therefore;
V₁ = A × h₁
V₂ = A × h₂
Which gives;
V₂ - V₁ = A × h₂ - A × h₁ = A×(h₂ - h₁)
Where:
A = Base area of the piston = 0.4 m²
h₂ - h₁ = Displacement of the piston
∴ 8 × 10⁴ J = 105 Pa × (V₂ - V₁) = 105 Pa × 0.4 m² × (h₂ - h₁)
h₂ - h₁ = (8 × 10⁴ J)/(105 Pa × 0.4 m²)
h₂ - h₁ = 1904.76 m
Hence the displacement of the piston = 1904.76 m.

Trees are being felled at an alarming rate by people. Forests are home to numerous animals and people, and by removing trees from them, we are destroying their habitat and depriving them of a safe haven.
What is community conservation?Community conservation refers to a strategy for protecting the environment that acknowledges local residents' rights to manage wildlife or gain both direct and indirect benefits from it.
The gorillas' habitat, the forest, is being destroyed by humans. Additionally, people are harming these creatures, and if this continues, gorillas may become extinct.
There won't be as many resources from trees, like paper, if people cut down less of them, therefore prices could rise.
Prices for tourists will increase if fewer gorillas are still alive. That won't benefit visitors since they will have to pay more, and since some individuals don't have a lot of money, there will be fewer visitors.
Thus, this way, community conservation is mandatory.

Explanation:
If this inclined plane moves 3 cm to the left how high will it lift the object
Answer:
It would lift the object to the same height than before you move it 3 centimeters to the left. You see, the height doesn't change if you move the inclined plane horizontally, because height is a vertical variable.
Therefore, if the inclined plane has a height of 1 meters, then the object will be lifted 1 meters up, no matter if you move the inclined plane 50 meters horizontally, it won't change its height.
When the Sun’s radiant energy falls on Earth’s oceans, it causes water to change state by evaporating. Which form of energy does water vapor have?
Answer:
water vapor is a type of gas
Explanation:
all gas are in air state of form
hope this helps
Answer:
chemical potential energy
Explanation:
When the sun's radiant energy falls on Earth's oceans, it causes water to change state by evaporating. The form of energy water vapor have is chemical potential energy. when heat energy of sun falls on water surface, its state change from liquid to gas. This gas rises above in the form of water vapor. Its a chemical change. If this vapor get condense/ cool, it will turn into liquid again. We can say that vapor has potential to transform into water again. Thus, the energy stored in water vapor is called chemical potential energy.

Um joalheiro recebe uma encomenda onde ele deve fazer alguns anéis de prata. Ele dispõe de um pedaço de 100 g de prata mas precisa derrete-lo para colocar a prata em moldes específicos e construir esses anéis. O principal problema desse procedimento é que a temperatura de fusão da prata é muito alta e requer condições especiais. A prata possui temperatura de fusão de 961 ºC, calor latente de fusão de 21 cal/g e calor específico no estado sólido igual a 0,056 cal/gºC. Determine a quantidade de calor aproximada para fundir as 100 g de prata sabendo que sua temperatura inicial é de 20°C. A 2,1 kcal B 0,5 kcal C 7,4 kcal D 5,3 kcal E 6,3 kcal
Answer:
Correct option: C -> 7.4 kcal
Explanation:
First we need to find the energy necessary to heat the silver from 20°C to 961°. The change in temperature is 961 - 20 = 941, so the energy necessary is:
941 * 0.056 * 100 = 5269.6 cal
Then, for the melting process, we will need:
21 * 100 = 2100 cal
So the total energy needed is:
5269.6 + 2100 = 7369.6 cal = 7.4 kcal
Correct option: C
