How do catalysts and inhibitors affect reaction rates
Please I'm in desperate help

Answers

Answer 1

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.

20 pts: Please write a paragraph about the big bang theory

Answers

The Big Bang is a scientific theory about how the universe started, and then made the stars and galaxies we see today. The Big Bang is the name that scientists use for the most common theory of the universe,from the very early stages to the present day.

The universe began as a very hot, small, and dense superforce (the mix of the four fundamental forces), with no stars, atoms, form, or structure (called a "singularity"). Then about 13.8 billion years ago,space expanded very quickly (thus the name "Big Bang"). This started the formation of atoms, which eventually led to the formation of stars and galaxies. It was Georges Lemaître who first noted (in 1927) that an expanding universe could be traced back in time to an originating single point. The universe is still expanding today, and getting colder as well.

As a whole, the universe is growing and the temperature is falling as time passes. Cosmology is the study of how the universe began and its development. Scientists who study cosmology have agreed that the Big Bang theory matches what they have observed so far.

Fred Hoyle called the theory the "Big Bang" on his radio show. He did not believe the Big Bang was correct. Scientists who did not agree with him thought the name was funny and decided to use it.

Scientists base the Big Bang theory on many different observations. The most important is the redshift of very far away galaxies. Redshift is the Doppler effect occurring in light. When an object moves away from Earth, its color rays look more similar to the color red than they actually are, because the movement stretches the wavelength of light given off by the object. Scientists use the word "red hot" to describe this stretched light wave because red is the longest wavelength on the visible spectrum. The more redshift there is, the faster the object is moving away. By measuring the redshift, scientists proved that the universe is expanding, and they can work out how fast the object is moving away from the Earth. With very exact observation and measurements, scientists believe that the universe was a singularity approximately 13.8 billion years ago. Because most things become colder as they expand, scientists assume that the universe was very small and very hot when it started.

Other observations that support the Big Bang theory are the amounts of chemical elements in the universe. Amounts of very light elements, such as hydrogen, helium, and lithium seem to agree with the theory of the Big Bang. Scientists also have found "cosmic microwaves background radiation". This radiation is known as radio waves, and they are everywhere in the universe. This radiation is now very weak and cold, but a long time ago it was very strong and very hot.

It can be said that time had no meaning before the Big Bang. If the Big Bang was the beginning of time, then there was no universe before the Big Bang, since there could not be any "before" if there was no time! Other ideas state that the Big Bang was not the beginning of time 13.8 billion years ago. Instead, some believe that there was a completely different universe before the Big Bang, and it may have been very different from the one we know today.

Nonetheless, in November 2019, Jim Peebles, awarded the 2019 Nobel Prize in Physics for his theoretical discoveries in physical cosmology.noted, in his award presentation, that he does not support the Big Bang Theory, due to the lack of concrete supporting evidence, and stated, "It's very unfortunate that one thinks of the beginning whereas in fact, we have no good theory of such a thing as the beginning."

On a sky coaster (human pendulum) that reaches 20 meters from it's equilibrium position, a man of 70 kg is able to reach a maximum speed of

Answers

Answer:

Explanation:

Using the principle of conservation of energy, the potential energy is converted to kinetic energy, assuming any losses.

Kinetic energy is given by ½mv²

Potential energy is given by mgh

Where m is the mass, v is the velocity, g is acceleration due to gravity and h is the height.

Equating kinetic energy to be equal to potential energy then

½mv²=mgh

V

Making v the subject of the formula

v=√(2gh)

Substituting 9.81 m/s² for g and 20 m for h then

v=√(2*9.81*20)=19.799 m/s

Rounding off, v is approximately 20 m/s

Answer:

19.8 m/s

Explanation:

During the motion of a pemdulum bob, it casually converts kinetic energy to potential energy and vice versa.

A pendulum bob reaches its maximum speed at a position closest to its equilibrium position and has its lowest when it is farthest from the equilibrium position.

The maximum speed of a pendulum bob based on the mass involved and the maximum displacement from the equilibrium position is obtained from

Maximum kinetic energy = Maximum potential energy

Maximum potential energy occurs at the farthest point from equilibrium, that is,

P.E(max) = mgh

Maximum kinetic energy = ½mv²

½mv² = mgh

v = √2gh

g = acceleration due to gravity = 9.8 m/s²

h = farthest height from equilibrium position = 20 m

v = √(2×9.8×20) = 19.8 m/s

A circuit has a current of 3 A. How many coulombs of charge will pass by a point in the circuit in 2 seconds?

- 6C

- 5C

- 3/2 C

- 2/3 C

One of these are the answer..

Answers

Answer:

6C

Explanation:

The quantity of charge, Q, passing through an electric circuit is dependent on the electric current, I, and the time taken, t, for the current to flow. It is given mathematically as follows

Q = I x t          ------------------------------(i)

Where;

I is measured in Amperes(A)

t is measured in seconds (s)

Q is measure in coulombs (C)

From the question,

I = 3A

t = 2s

Substitute these values into equation (i) as follows;

Q = 3 x 2

Q = 6C

Therefore, the number of coulombs of charge that will pass is 6C

A charge of 80 coulombs passes through a circuit in 5 seconds. What is the current through the circuit?

Answers

Answer:

I = 16amp

Explanation:

Charge coulomb ( Q ) = It

Where I =current in ampere

t = time = 5 seconds

80 = I × 5

I = 80/5

I = 16amp

The current through the circuit will be I = 16amp

The word gymnosperm comes from two Greek words: gymno, meaning bare, and sperm, meaning_____ . Unlike other seed plants, gymnosperms do not have a protective _______ around their seeds. Most gymnosperms have needle-like or scale-like ______.

Answers

Answer:

Seed, Fruit, Leaves

Explanation:

Gymno, meaning bare, and sperm, meaning seed. Unlike other seed plants, gymnosperms do not have a protective fruit around their seeds. Most gymnosperms have needle-like or scale-like leaves.

What are gymnosperms?

A relatively tiny class of plants known as gymnosperms produce seeds and lack flowers. This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.

Gymnosperm can also be referred to by the less common word acrogymnospermae. It's a broad name for plants like conifers, ginkgo, cycads, and gnetophytes that you probably already know about. The word "gymnosperm" has Greek roots. The tube cell, the generative cell, and two prothallial cells make up the gymnosperm pollen grain's four cells.

Conifers make up the majority of the plant species in the gymnosperm family. In contrast to angiosperms, which produce flowers, gymnosperms create cones as their reproductive organs. Gymnosperms primarily consist of conifers, such as pine trees.

You have a bowling ball with you in the canoe. If you carefully drop the bowling ball over the side of the canoe and it sinks to the bottom of the pool, does the water level in the pool rise or fall?

Answers

Answer:

lower

Explanation:

When you move the ball from your canoe to the water causes the water level to fall

If you carefully drop the bowling ball over the side of the canoe, and it sinks to the bottom of the pool, the water level in the pool will fall.

How to measure water level?

Both the bowling ball and the canoe will float on top of the water when they are in a canoe because they will displace more water than they can hold. However, if dropped, the ball will plummet to the bottom of the pool.

The bowl sinks because it is denser than water. The ball will in this scenario move less water than its own volume.

Therefore, when the ball is with you in the canoe in the second scenario, the volume of water displaced will be less than in the first example. Consequently, lower volume

Therefore, the water level in the pool will drop if you carefully toss the bowling ball over the side of the canoe and let it land at the bottom of the pool.

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

Answers

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.

You get yourself a new mirror so that you can admire yourself in the morning. When you open the box, you notice that it is only ½ your height. You think to yourself "This is no good! Now I can't see all of me!" You put it up anyway and realize that you can see your entire body in it. How can this be?

Answers

Answer:

Because you stand at a distance from the mirror at which your entire body shows.

Explanation:

Since the mirror is a plain mirror, the distance of the object from the mirror is also the distance of the image from the mirror. Also since the magnification is 1 for a plane mirror because the height of the image equals the height of the object. Since the magnification always equals 1, for you to be able to see your entire body, you must stand at a distance from the mirror such that your height equals the image height.

Answer: By keeping a distance away from the mirror.

Explanation:

If it's a plane mirror, it's possible to see your entire body by keeping distance away from the mirror. The distance of the object away from the mirror is equal to the distance of the image away from the mirror.
