A seesaw remains stationary when two students of equal weight sit on the ends

c

Answer:

the answer is c.

Explanation:

a balanced force is a constant motion, or when the object does not move. because the children have the same weight, they can manage the seesaw to stay still.

Answer:

the answer is D.

Explanation:

while A may look similar, it says the forces are unbalanced, which is not the case in this situation. If there is no change in the apple's motion, then it is a balanced force.

The force of Kerrick’s hand pushing up on the apple is equal to the force of gravity pulling down on the apple. Since the forces are balanced, the apple does not move. So, option (D) is correct.

In mechanics, gravity—also known as gravitation—is the constant force of attraction that pulls all things together. It has little impact on determining the intrinsic characteristics of common stuff because it is by far the weakest known force in nature. In contrast, it governs the formations and evolution of stars, galaxies, and the entire cosmos by its extensive and ubiquitous action, which affects the trajectories of objects in the solar system and beyond the universe.

All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass. The acceleration that gravity gives to objects falling freely serves as a gauge of its strength. The acceleration of gravity at Earth's surface is approximately 9.8 meters per second.

As The force of Kerrick’s hand pushing up on the apple is equal to the force of gravity pulling down on the apple and the forces are balanced, the apple does not move.

Answer:

the answer is C.

Explanation:

specifically, as a tennis player, Amira is completely wrong. Balanced forces are when an object has equal forces acting on it. When Amira hits the tennis ball, it bounces off and (maybe) over the net (if she aims it correctly). Hitting a tennis ball is an unbalanced force because you are hitting it in a different direction with enough force to make it change direction.

The force on the ball is not balanced, because she hits the ball with more force in the forward direction, so option C is correct.

In the body, force is the result of either a push or a pull. The three main categories of forces are friction, nuclear, and gravitational. For instance, when a hand strikes a wall, the hand puts force on the wall and the wall also exerts a force on the hand. Newton was given a variety of laws to help him understand force.

Newton is a physics unit of force that is a part of the International System (SI). A newton is the amount of force needed to move a body weighing one kilogram one meter per second.

Specifically, Amira is totally incorrect in terms of tennis. The presence of equal forces operating on an object is known as balanced forces. The tennis ball bounces off and (maybe) crosses the net as Amira strikes it (if she aims it correctly). When you strike a tennis ball, you are applying an imbalanced force since you are striking it in a different direction and hard enough to cause it to alter course.

Therefore, the force on the ball is not balanced, because she hits the ball with more force in the forward direction.

Explanation:

Only power plants use fossil fuels to transform energy.

The process of changing one form of energy into another form or the transfer of energy from one location to another is referred to as energy transformation.

Here,

A power plant is a facility that transforms heat energy into electricity. Typically, coal is used by thermal power plants to generate heat.

With the aid of one or more generators that transform various energy sources into electric power, a power plant is an industrial facility used to create electricity.

The water that is kept behind a dam can store electricity in a hydroelectric plant. Potential energy is changed into kinetic energy when water flows from higher altitudes.

Kinetic energy is changed into mechanical energy as the turbine rotates due to the water flow.

Hence,

Only power plants use fossil fuels to transform energy.

Answer:C

Explanation:All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.

Answer: A) The amount of heat radiated from the atmosphere to the surface (sometimes called “back radiation”) is equivalent to 100 percent of the incoming solar energy.

B)On its northward journey, the water at the surface absorbs gases like carbon dioxide and chlorofluorocarbons (CFCs) – the latter are, to a large extent, the gases responsible for the ozone hole over Antarctica – as well as excess heat from the atmosphere

C)Water droplets and ice crystals that make up clouds scatter light equally at all wavelengths and therefore appear white. Reflection of solar radiation occurs when the radiation is sent directly backward from a surface. The fraction (or percentage) of radiation reflected back is known as albedo.

D)Clouds cool Earth's surface by reflecting incoming sunlight. ... Clouds warm or cool Earth's atmosphere by absorbing heat emitted from the surface and radiating it to space. Clouds warm and dry Earth's atmosphere and supply water to the surface by forming precipitation

The animals that you read about get the energy storage molecules they need for reproduction from the food they eat. Food provides the energy and nutrients required for various biological processes, including reproduction.

Reproduction is the biological process by which organisms produce offspring, either sexually or asexually, to ensure the survival and continuation of their species. It is an essential characteristic of living organisms and is critical for the maintenance of genetic diversity within a population.

Sexual reproduction involves the fusion of gametes (reproductive cells) from two parents, which results in the formation of a new individual with a unique combination of genetic material. In most sexual reproduction processes, the male produces sperm, while the female produces eggs. The sperm and egg unite during fertilization, which creates a zygote that develops into a new organism.

Asexual reproduction, on the other hand, involves the production of offspring from a single parent without the fusion of gametes. The offspring produced through asexual reproduction are genetically identical to the parent, except for mutations that may occur during the process.

Reproduction is essential for the continuation of a species and is responsible for maintaining the genetic diversity within a population. It also plays a critical role in the evolution of species by allowing for the accumulation of genetic variation through sexual reproduction and mutation.

Here in the Question,

The three main macronutrients in food that provide energy for the body are carbohydrates, proteins, and fats.

These macronutrients are broken down during digestion into smaller molecules such as glucose, amino acids, and fatty acids, which can be used by the body to produce energy through cellular respiration.

The energy produced from food is stored in the form of adenosine triphosphate (ATP), a molecule that provides energy for various cellular processes, including reproduction. Animals obtain their energy storage molecules such as ATP through the process of cellular respiration, which occurs in the mitochondria of cells.

Therefore, animals get the energy storage molecules they need for reproduction from the food they eat, which provides the necessary nutrients and energy required for various biological processes.

Explanation:

C which is oxygen all the rest are greenhouse gases, but I don't think oxygen itself is one

Oxygen is not an example of a green house gas.

A greenhouse gas is any gas that is capable of trapping infrared rays  close to the earth surface thereby preventing its escape leading to a gradual rise in the temperature of the earth called global warming. The earth keeps getting hotter due to global warming

Global warming has led to the melting of polar ice caps and consequent flooding in some parts of the world.

Greenhouse gases are contributing to the gradual rise of the temperature of the earth as they prevent the escape of infrared rays.Human activities such as burning of fossil fuels for energy supply are exacerbating the menace of greenhouse gases in the atmosphere

Carbon Dioxide, Methane and Nitrous Oxide all contribute to global warming but oxygen gas does not.
