Answer:
[tex]a=123.04\ m/s^2[/tex]
Explanation:
Given that,
Force applied to a soccer player, F = 56.6 N
The mass of the ball, m = 0.46 kg
We need to find the acceleration of the soccer ball. The force acting on the ball is given by :
F = ma
Where
a is the acceleration
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{56.6 }{0.46 }\\\\a=123.04\ m/s^2[/tex]
So, the required solution is [tex]123.04\ m/s^2[/tex].

Which substance do plants use to capture light energy from the sun? a) Carbon dioxide b) Chlorophyll c) Glucose d) Oxygen
Answer: chlorophyll
Explanation:
The substance that plants use to capture light energy from the sun is referred to as chlorophyll.
The chlorophyll is a colored pigment that is used by the plants for photosynthesis. The function of the chlorophyll is that it absorbs the energy from the sun which is then turned into a chemical energy.

A larger bullet does not necessarily have more momentum than a smaller bullet Explain why
Answer:
yes
Explanation:
a larger bullet weighs more then a smaller bullet so the smaller bullet goes faster.
Answer:
Explanation:
Momentum is dependent on mass and velocity. So, the smaller bullet can be moving at a much greater speed than the larger one.
Mendel also developed the law of
dominance. He did many experiments
with pea plants. This is how he came
up with the law. It shows how certain
traits come to be. One allele is
dominant. It exerts a greater influence.
He based this on an uncertain belief
that each plant carried two trait units.
One of them dominated the other.
Which sentence from this paragraph explains what a dominant allele does?
A. Mendel also developed the law of dominance
B. He did many experiments with pea plants
C. It exerts a greater influence
D. He based this on an uncertain belief that each plant carried two traits
Answer:
They mask the recessive alleles
Among the alkaline earth metals in Group 2A/A, which is more reactive - beryllium (element 4) or strontium (element 38)?
Answer:
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A.
Explanation:
Aluminum has metallic bonds between its atoms. Which statement BEST describes the
valence electrons in aluminum?
are exchanged with nonmetal atoms
are exchanged with other metal atoms
are localized and stay between metal atoms
are delocalized and move between metal atoms
Look at picture
ASAP please will mark as brainlist don’t got much time
Answer:
are delocalized and move between metal atoms
Explanation:
As the problem says, aluminum has metallic bonds. The main characteristic of metallic bonds is that the electrons are free to move between the metal ions (they are delocalized), thus being responsible for the good electrical conductivity of metals.
What is the natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America? Is it the Jet Stream, the Gulf Stream, La Niña, or El Niño? This is a science question about weather.
Answer:
El Niño
Explanation:
The natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America Is the El Niño.
El Niño is a climate pattern that happens when there is an unusual warming of the surface temperatures of the Pacific Ocean. This occurs at an interval of two to seven years
During El Niño, the surface waters of the Pacific Ocean become warmer than average and this is as a result of the weakness of trade winds which blows over the entire Pacific Ocean. This makes the atmospheric pressure above the ocean to decrease.
El Niño brings rainfall nd flooding to South America and droughts in the western United States

The Big Bang Theory is a hypothesis that states that all matter
and energy were at one time compressed into a small volume
and then _________
Answer:
I’m not sure how they want you to answer the fill in blank.
Explanation:
The Big Bang is a theory where 14 billions years ago all matter and energy in the universe was compressed into an extremely small volume that exploded and began expanding in all directions.
The big bang theory is a hypothesis that states that all matter and energy were compressed into a small volume at one time and then expanded outward.
What is Big Bang Theory?The big bang model of the universe can be described as the model to identify the beginning of the universe. The big bang model is a cosmological model which is described by the software development life cycle.
The Big Bang theory is the dominant model of the observable universe from its beginnings to large-scale evolution. This model explains how the universe is expanded from a state of high density and temperature. It provides an explanation for phenomena, such as cosmic microwave background radiation, the abundance of light elements, and large-scale structure.
Due to the big bang as we know, the universe has been created existing about 12 - 15 billion years ago. According to the theory that the Big bang was a gigantic explosion that formed all of the energy and mass in less than a second in the universe.

How can you measure the volume of an irregular shaped solid?
Answer:
If the object has an irregular shape, the volume can be measured using a displacement can. The displacement can is filled with water above a narrow spout and allowed to drain until the water is level with the tap. As the irregular object is lowered into the displacement can, the water level rises.

A 0.50 M solution of H Br is to be poured into a beaker that initially contains 50 g of solid CaCO3. Determine the volume of H Br that will be needed to completely react with the 50 g of solid CaCO3.
Answer:
2 liters of HBr is needed to completely react with the 50 g of salt.
Explanation:
First of all, we determine the reaction:
2HBr + CaCO₃ → CaBr₂ + CO₂ + H₂O
We need to calculate, moles of carbonate in order to state the stoichiometry (1:2)
50 g . 1mol / 100.08g = 0.499 mol
1 mol of salt need 2 moles of acid to react, according to stoichiometry
Then, 0.499 moles of salt, will react with (0.499 . 2)/1 = 0.999 moles
As we have the [HBr], we can calculate the volume.
M = mol/L → we replace → 0.50 mol/L = 0.999 mol /L
L = 0.999 mol/0.50 mol → 1.99 L ≅ 2L

Which of the following factors does NOT affect surface currents?
A. Coriolis effect
B. density
C. continental deflection
D .wind
The only factors that doesn't affect surface current from the question is B:
density.
Surface currents can be regarded as current that is been formed as a result of Earth's rotation as well as changes in temperature.Surface currents is know as one of the determinant for climate. These currents is responsible for the bringing of warm water from the equator then transfer it to the cooler parts of the ocean as a result of this heat energy is transferred.Some factors that influence surface current are; Coriolis effect : This also aid the movement of the currentcontinental deflection : this helps the deflection of the currents from the continental land masses.wind : without wind there cannot be transfer of the warm water from the equator to the part of the ocean that is cool.Therefore, Option D is correct because density does affect the surface current.

Write about similarities and the differences of the plant and animal cell
Answer:
Mark me as brainliest pls
Explanation:
similarities: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal element
differences: A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.
