(A) When a positively charged atom loses an electron to a positively charged atom, two neutral atoms are created.
(B) When a neutral atom loses an electron to another neutral atom, two charged atoms are created.
( C ) When a neutral atom loses an electron to a positively charged atom, both atoms become neutral.
(D) When charged atoms lose electrons they will become positively charged atoms.
Answers
Answer:
When a neutral atom looses an electron to another neutral atom, two charged atoms are created.
Explanation:
On the off chance that one of the two unbiased particle looses an electron, it turns out to be emphatically (charge: +1), in light of the fact that the electron conveys a charge of - 1. Thus, the other atom which acknowledges the electron turns out to be adversely charged (charge: - 1). And in the end, we will have two charged atoms.

In this activity, you modeled the Sun–Earth–Moon system. If you removed one object from this system model, would the model still explain the changes to the Moon’s appearance?
Answers
The correct answer is NO because the moon appearance is relatively base on the positioning of Sun - Earth - Moon
What is the nature of Moon ?A moon is an opaque object. It does not give or illuminate light on its own, It reflects light from from the sun to the earth. The appearances of moon are;
waxing crescentwaxing gibbouswaning crescentwaning gibbousIn this activity, if you modeled the Sun–Earth–Moon system and you remove one object from this system model, would the model still explain the changes to the Moon’s appearance?
The answer is capital NO.
The reason is simply because the moon appearance is relatively base on the positioning of Sun - Earth - Moon relationship. That is, the moon appearances of waxing crescent, waxing gibbous, waning crescent and waning gibbous, all depend on the position of the Sun, Moon and the earth.
Therefore, If you removed one object from this system model, the model cannot explain the changes to the Moon’s appearance again.

You are working on your senior year science fair project. Your idea is to develop a demonstration to show evidence of how cellular respiration and photosynthesis depend on each other. Your presentation will show how cellular respiration is the process by which all cells transform food into energy, whereas photosynthesis is the process by which plants obtain food. Your experimental design should show evidence of how cellular respiration and photosynthesis depend on each other.
Answers
By using one animal and one plant or tree in an experiment to show that cellular respiration and photosynthesis depend on each other.
How do cellular respiration and photosynthesis depend on each other?The process of Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the producers whereas oxygen is a by-product that is used in the process of respiration and the extra will diffuse in the atmosphere. In the cellular respiration process, oxygen and glucose are converted into water and carbon dioxide. Water and carbon dioxide are the waste material and ATP is the energy that is used in the process. In the photosynthesis process, carbon dioxide gas combines with water molecules forming glucose and oxygen gas while on the other hand, in the process of respiration, glucose combines with oxygen gas forming carbon dioxide gas, water, and energy in the form of ATP. This ATP is used for performing different activities by the cell.
So we can conclude that using one animal and one plant or tree in an experiment to show that cellular respiration and photosynthesis depend on each other.

What is the answer to mgh =1/2 mv^2 + 1/5 mv^2 ???
Answers
Answer:
v = sqrt((10/7)gh)
Explanation:
The given equation is:
mgh = (1/2)mv^2 + (1/5)mv^2
To solve for v, we can start by simplifying the right side of the equation:
mgh = (7/10)mv^2
Dividing both sides by (7/10)mv^2, we get:
mgh / (7/10)mv^2 = 1
Multiplying both sides by (10/7)m/gh, we get:
v^2 = (10/7)gh
Taking the square root of both sides, we get:
v = sqrt((10/7)gh)
Therefore, the solution for v in terms of m, g, h is:
v = sqrt((10/7)gh)

What fraction of the Moon model was always lit up by the light in your model?
Answers
Answer:10
Explanation:
In the context of the Moon model, the fraction of the Moon that was always lit up by the light is half, or 1/2.
The explanation for this is that the Moon model discussed previously most likely depicts the Moon's phases as seen from Earth. The phases of the moon are caused by distinct areas of the lit side of the moon that are visible from Earth at various times during its orbit.
The Sun always illuminates half of the Moon's surface, leaving the other side in darkness. From Earth, we can only see the bright portion; the unlit portion is invisible. Different phases result from variations in the visible fraction of the lighted half of the Moon as it revolves around the Earth.
Therefore, the fraction of the Moon that was always lit up by the light is half, or 1/2.

why is it difficult for a car to round a curve at high speed
Answers
Answer:
Because the force required to produce this acceleration equals the mass of the car x acceleration, the group of the car is the same but the acceleration is a lot more hence a much bigger force is required. So this is why it's harder for cars to corner at a high speed rather than lower.
Answer:
Vehicles are heavy and have a lot of inertia. This means that if you drive too fast on a curve, your vehicle will keep going straight instead of going around the curve, no matter how hard you drive or slow down to keep it in your lane. Centrifugal force creates a strong outward pull on your vehicle. So all you need to do is slow down before entering a corner. Reducing your speed when you are already on a bend can cause your car to skid.

Explain what happens as the heart grows bigger.
Answers
Initially, the heart may grow bigger as a compensatory mechanism to try to keep up with increased demands for blood and oxygen. For example, if a person engages in regular exercise, their heart may enlarge to accommodate the increased demand for blood and oxygen to the muscles.
However, if the heart continues to grow over time, it can become less efficient at pumping blood and may develop structural abnormalities that increase the risk of heart failure, arrhythmias, and other complications.
In some cases, cardiac hypertrophy may be reversible if the underlying cause is treated, such as by managing high blood pressure or heart disease. However, if left untreated, hypertrophy can lead to irreversible damage to the heart muscle and may require more aggressive interventions, such as medication, surgery, or other medical procedures to manage the condition.

The work input = _____.
F i ÷ d i

Answers
The work input = Fi × di
How to solve for work input?To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:
Work Input = Force × Distance × cosθ
Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:
Work Input = Force × Distance
For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:
Work Input = 50 N × 10 m × cos(0°) = 500 Joules

Black to move and capture a hanging piece . Select the best move
A) Nxg3
B) Bxg3
C) Qxg5
Answers
Answer: A
Explanation:The Pawn moves directly forward, never backward or to the side. Pawns capture a piece that is one square diagonally forward. Though Pawns normally cannot move diagonally, this is the only way they capture.
Based on the information provided, the best move to capture a hanging piece would be: A) Nxg3
What would be the best move to capture a hanging piece ?Nxg3 would be the best move to capture a hanging piece.
This move involves sacrificing the knight to capture the hanging piece, which could be a bishop or pawn, depending on the position of pieces. After Nxg3, the opponent may capture the knight with different piece, but the player who made the move will have successfully captured the hanging piece.
However, it's important to note that the best move ultimately depends on the overall strategy of the player and the position of the other pieces on the board.
