The two types of force.In Science, there are two (2) main types of force and these include:
Unbalanced forceBalanced forceWhat is a balanced force?A balanced force is only produced when two or more forces that are acting on an object (book) are equal in magnitude and as such, it does not result in a change of motion (acceleration).
Generally, the magnitude of acceleration of an object decreases (reduces) when a balanced force acts on it.
In conclusion, the book would stay still on the desk because the forces acting on the book are balanced.

Explain where you observe reflection, refraction, and absorption of light in your everyday activities (10 points)
Answer:
Reflection: looking in window reflection. Refraction: You put a straw in a glass of water, and it looks like it broke. Absorption: If you have a black sweater and you wear it out in the cold, the black sweater is going to hold in heat better than a lighter sweater because the black sweater absorbs light .

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

Each question below carries 10 marks.
1) How does the cryosphere help regulate Earth's temperature?
2) What kind of organisms are found in oceanic trenches? Describe.
3) Explain how an Estuary can support a wide variety of food webs.
4) List out and describe the factors that help meteorologists forecast weather.
Answer:
ans 1 ; It also includes frozen rivers and lakes, which mainly occur in polar areas. The components of the cryosphere play an important role in the Earth's climate. Snow and ice reflect heat from the sun, helping to regulate our planet's temperature.
ans 2 ; Deep-sea trench, also called oceanic trench, any long, narrow, steep-sided depression in the ocean bottom in which occur the maximum oceanic depths, approximately 7,300 to more than 11,000 metres (24,000 to 36,000 feet). They typically form in locations where one tectonic plate subducts under another.
ans 3 ; The calm waters provide a safe area for small fish, shellfish, migrating birds and shore animals. The waters are rich in nutrients such as plankton and bacteria. Decomposing plant matter, called detritus, provides food for many species. ... This means the estuary must support a wide variety of food webs.
ans 4 ; Weather can be defined as the condition of the atmosphere at any given time and place. Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.

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.

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.
Explanation:
Amira hits a tennis ball with her racket. The tennis ball flies across the tennis court. She says that hitting the tennis ball is an example of balanced forces. Is she correct?
A.
Yes, because the forces acting on the ball are equal on all sides.
B.
Yes, because she hits the ball with more force in the forward direction.
C.
No, because she hits the ball with more force in the forward direction.
D.
No, because the forces acting on the ball are equal on all sides.
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.
What is force?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.
