Friction is a force exerted in the direction opposite to an object's motion, which means friction will cause an object's
velocity to decrease.
-true or false?
Answer:
true
Explanation:
think of a box, if you push it on a smooth floor without friction it would glide pretty easy
but put it on say carpet, the friction from the carpet would not allow the box to move very far
that's also how brakes work, they apply friction to the wheels in order to get them to reduce motion

Like a chimney we make heat to warm up our houses! Or some people use furnaces it also produces heat and warms up your room or house! Well now that we know what we use it for ....What is heat?
Of course Heat!
Heat is The energy that transfers to many different entities With a slight or major temperature difference!Please take in mind that heat only transfers to objects that are cooler than heat itself!Which means that it is energy that is transferred (or that flows ) from one object or system to another!
More info!
What are the 3 types of heat?Conduction, Convection, and Radiation.Heat can be measured in Btu, calories or joules what we use to measure heat is hermometers and pyrometers!

The layers of the atmosphere are determined based upon air temperature, which has to do with the energy of the molecules in the air. Where does this energy originally come from?
Answer:
The layers of the atmosphere are determined based upon air temperature, which has to do with the energy of the molecules in the air. Where does this energy originally come from?
Explanation:
The layers of the atmosphere are determined based on air temperature, the energy in the air molecules comes from the sun, which increases the temperature of the atmosphere.
What are the layers of atmospheres?There are different layers of the atmosphere. There are seven layers of atmosphere. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The sun is the only source of energy for the atmosphere. It provides heat or thermal energy and which is acquired by different molecules and these molecules convert this energy into other forms of energy.
Thus, the energy contained in the molecules of the air is derived from the sun, which raises the temperature of the atmosphere, which in turn determines the layers of the atmosphere.

Lungs in humans and many other species branch out into many tubes until they end in small sacks called alveoli. These alveoli allow oxygen to enter the blood through the capillary beds as pictured above. Alveoli provide much more surface area for the lungs to contact the capillary beds. What is the advantage of lungs with alveoli compared to lungs without alveoli?
Answer:
It provides more surface area for the absorption of oxygen.
Explanation:
The advantage of lungs with alveoli compared to lungs without alveoli is the availability of large surface area for the oxygen absorption. Alveoli allows oxygen from the air to pass into your blood. There are 480 million alveoli are present in human lungs, this large number and small size of alveoli provides lungs a large surface area to volume ratio so we can conclude that the lungs work better with the help of alveoli as instead of lungs without alveoli.

Hello my name is Tobie and I will be more than glad to help!
your answer should be alpha particle
consisting of two protons and two neutrons emitted by radioactive materials we get what is called a alpha particle
they are usually formed when identical to the nucleus of the helium-4 atom are emitted by radioactive matter !
What can they do to the body?
Since they have radioactive material in them they are very DANGEROUS! If they are inhaled swallowed or somehow get inside our bodies it can cause serious harm!They can harm sensitive living tissue and can go as far as to causing cancer !

Earth is the only planet that is known to support life. Almost two-thirds of Earth's surface is covered with water. It has a rocky terrain consisting of deep valleys and high mountains. Earth is neither too far nor too near to the Sun. This ensures that there is enough sunlight to maintain moderate temperatures on Earth. Which three factors would be most important for a body in the Solar System outside of Earth to support life?
Answer:
My guess would be an energy source, water, and an atmosphere.
Explanation:
Whatever lives there is going to need energy and water to survive. The atmospheric layer will protect the planet like ours protects Earth. Hope this helps! :)

A fire sits 72 feet from the abs of 125 foot tall building. Find the angle of Evel at ion from the fire to the top of the building
Answer:
60°
Explanation:
From the attachment,
Opposite side of the triangle= 125 feet
Adjacent=72 feet
Angle of elevation= (θ)
From trigonometry,
Tan (θ)= Opposite side /Adjacent adjacent
Where
(θ)=angle of elevation
If we substitute to above expresion we have
tan(θ)= 125/72
tan(θ)= 1.736
Tan^-1(1.736)=60°
θ= 60°
Hence, the angle of Evel at ion from the fire to the top of the building is 60°

With over 600 muscles in the body we are able to do an array of motions. What is the difference between what big muscles, like the four in the quadriceps, can do and what those like the thirty in our hands can do?
The functions of each muscle depend on its location and ability to perform specific work. For example, the masseter muscle is the strongest muscle in humans which is present in the jaw.
What is the significance of muscles?The significance of muscle is understood by the fact that these structures are linked to bones, internal organs, and blood vessels. These components are responsible for movement by their contractions.
According to the context of this question, the muscles in the shoulder region are the four rotator cuffs which significantly include the supraspinatus, infraspinatus, teres minor, and subscapularis. The four muscles in the quadriceps have to perform a different function which includes heavy weightlifting, so, they have to strongest enough.
While the thirty muscles present in the hand can do numerous functions with different levels of intensity. These muscles are not too strong as compared to masseter but are superior.
Therefore, the functions of each muscle depend on its location and ability to perform specific work.
