Given:
M=10KG
F=42N
Opposing Force=6N
If we can recall F=ma, we can easily calculate the acceleration by substituting the given variables; but in our case, we have an opposing force. So we have to subtract the opposing force from the horizontal force.
F = ma
42N-8N=10KG x a
34N = 5KG x a; divide both sides by 10KG for a to be sole variable
34kg m/s^2) / 10kg x a (Newtons are sometimes referred to as kg m/s^2)
3.4 m/s^2 = a ; (kg's are cancelled)
Therefor, our acceleration is 3.4 m/s^2.

Answer:
For the first one it is solar and for the second it is mechanical.
As per the image given in the question, it uses solar energy for the first, and mechanical energy for the second.
What is Electrical energy?When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible. When two charge are in opposition to one another, they repel one another.
The term "neutral" refers to an object has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand for taking into account quant phenomena.
Electrical charge is a preserved attribute, meaning that the net charged of an isolated system—that is, the sum of the positive and negative charges—cannot change. Particles at the subatomic level carry an electric charge.

Ο Ο Ο Ο
Answer:
Increasing the mass and decreasing the distance between the two objects.
Explanation:
An increase in mass will cause them to have a stronger pull or gravity. A decrease of distance will make it easier for the objects to fall into each other because they would be further into the other objects area of influence.

CALCULATE: find the velocity of a wave in a wave pool if it's wavelength is 3.2 m and its frequency is 0.60 Hz
1. V = 1.29 m/s
2. V = 1.3 m/s
3. V = 1.92 m/s
The velocity of a wave in a wave pool if it's wavelength is 3.2 m and its frequency is 0.60 Hz V = 1.3 m/s.
What is Velocity?
Velocity is defined as a vector measurement of the rate and direction of motion. Velocity is the speed at which something moves in one direction.
The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.
As you might have guessed, the scalar (absolute value) magnitude of the velocity vector is the speed of motion. In calculus terms, velocity is the first derivative of position with respect to time.
Therefore, The velocity of a wave in a wave pool if it's wavelength is 3.2 m and its frequency is 0.60 Hz V = 1.3 m/s.

Answer:
Ty has two pet mice. One mouse has the gene for black fur color and the other mouse has the gene for white fur color. The female mouse is pregnant now, and Ty wonders what color or colors the baby mice will be. Read each offspring description phrase below and select the correct pattern of dominance for each.
___ all white fur offspring, white fur in this case is dominant
___ all gray fur offspring, this is incomplete dominant.
___ all black fur offspring, this is black fur dominantice
___ all black and white offspring, this is codominance .
Explanation:
Incomplete dominance: Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both alleles. It is also called semi-dominance or partial dominance.
Codominance: Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
Ty keeps two mouse pets. One mouse possesses the gene for black fur, while the other mouse possesses the gene for white fur. Ty wonders what colour or colours the baby mice will be now that the female mouse is pregnant. Select the appropriate pattern of dominance for each offspring by reading the offspring description phrase below.
What pattern of dominance for each?Incomplete dominance: When a dominant allele, or form of a gene, cannot fully suppress the effects of a recessive allele, the organism's physical characteristics reflect a blending of both genotypes.
Codominance: Codominance is the association of two genetic variants. A person inherits one allele—also known as a gene allele—from each parent. When the alleles are different, the dominant allele typically manifests, while the effect of the other allele—known as the recessive allele—is concealed.
Therefore, All white fur offspring, white fur in this case is dominant. This is incomplete dominant since the progeny are all gray fur.All black fur offspring, this is black fur dominant ice. This is codominance—all the kids are black and white.

Four boxes are sliding with constant speed before each box experiences and unbalanced force of 8 N. Which box would experience the greatest acceleration when the unbalanced force is applied? Answer choices: A) The box with a mass of 2 g B) The box with a mass of 4g C) The box with a mass of 6 g D)The box with a mass of 8 g
Answer:
d
Explanation:
Acceleration is defined as rate of change of velocity with respect to time.
The box with mass of 2 g experience the greatest acceleration.
Force at any object is defined as product of its mass and acceleration.
That is, [tex]F=ma\\\\a=\frac{F}{m}[/tex]
Where F is force, m is mass and a is acceleration of object.
F = 8 N is given.
Acceleration of the box of 2 g = [tex]\frac{8}{2}=4 m/s^{2}[/tex]
Acceleration of the box of 4 g = [tex]\frac{8}{4}=2m/s^{2}[/tex]
Acceleration of the box of 6 g = [tex]\frac{8}{6}=1.34m/s^{2}[/tex]
Acceleration of the box of 8 g = [tex]\frac{8}{8}=1m/s^{2}[/tex]
Therefore, box with mass of 2 g experience the greatest acceleration.

Does a wooden or plastic ruler have more elastic energy?
A wooden ruler is likely to have more elastic energy than a plastic ruler.
What is elastic energy?The elastic potential energy of an object is proportional to its elasticity, which in turn is related to its Young modulus. Young's modulus is a measure of how much a material will deform under a given amount of stress.
When a ruler is bent, elastic potential energy is stored in the material. When the ruler is released, the stored energy is released and the ruler returns to its original shape.
Compared to plastic, wood is generally stiffer and less elastic, which means it has a higher Young's modulus. This means that a wooden ruler can store more elastic potential energy than a plastic ruler when bent by the same amount.
Thus, A wooden ruler is likely to have more elastic energy than a plastic ruler.

Your teacher gives you a mystery species to investigate. She wants you to determine the mystery species’ kingdom. She gives you the following clues:
● The mystery species can perform photosynthesis.
● The mystery species is multicellular.
● The mystery species has a cell wall.
After receiving the clues you start to eliminate the kingdoms into which you know your species does not belong. Which of the following explanations is accurate?
A.
I can eliminate both bacteria kingdoms because bacteria are multicellular.
B.
I can eliminate the animal kingdom because all animals are unicellular.
C.
I can eliminate the animal kingdom because animals do not have cell walls.
D.
I can eliminate the animal kingdom because they have cell walls but cannot perform photosynthesis.
I can eliminate the animal kingdom because animals do not have cell walls. So, the correct option is C.
It is given that the mystery species can perform photosynthesis, they are multicellular and also the mystery species has a cell wall.
The only kingdom of species that does not have a cell wall is the kingdom animalia. Since, the function of cell wall is to provide rigidity and reduces the flexibility of cells, they are not present in animals. The presence of cell wall in animals will make them less flexible and affects their free movement. So, I can eliminate the animal kingdom from the mystery species.
