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.
What is gravity?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.

1. What impact did Portugal have on Latin America? Is it still evident today?
2. How did African slavery change the culture of much of the Caribbean and South America?
3. How did Spain have a dramatic impact on most of Latin America that is still evident today?
Answer:
Explanation:
1: Portugal still greatly impacts Latin America, specifically Brazil. One of Brazil's official languages is Portuguese
2: Slavery has also greatly impacted the Caribbean and Latin America, with many people being of African descent in this countries, and countries like Haiti were created because of slavery.
3: Spain pretty much created Latin America, because most countries were colonized by Spain, and much of Spanish culture and the Spanish language remains.

As radiation from the sun reaches the earth, the energy is-
A ) Immediately radiated back into space.
B ) Absorbed by only the oceans
C ) Radiated, reflected, and absorbed
D ) Only reflected by clouds in the atmosphere
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

What are the three stances in golf?
Answer:
P1: Address.
P2: Club Shaft Parallel With Ground On Takeaway.
P3: Lead Arm Parallel With Ground.
The center of your upper spine, your knees, and balls of your feet should line up on top of each other.
Answer:
A golf stance is made up of several elements – the right width of stance, the right amount of knee flex, the angle of the feet and overall posture. We'll look at posture in part 6 of this series. A stance that is too narrow will prevent you from generating a lot of power in your golf swing.

Which best describes a difference between energy transformations in power plants and dams?
Only power plants use fossil fuels to transform energy.
Only dams use fission to generate thermal energy.
Only power plants use water to turn turbines.
Only dams use mechanical energy to produce electricity.
Answer:
a
Explanation:
Only power plants use fossil fuels to transform energy.
What is meant by energy transformation ?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.

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.
