Answer:
A. respiration.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
Hence, the conversion of sugar to energy in the presence of oxygen is respiration.

Explanation:
Joni plays a scale on her clarinet. As she plays from low notes to high notes, what happens to the sound waves that the clarinet creates?
Answer:
The answer is "The frequency of the sound waves increases".
Explanation:
Its most oscillating their frequency waves, therefore higher the vibration we hear. However you see, sound frequency is determined through the oscillation of electrical signals while moving to our ears, which implies that perhaps the audio medium, which usually is air, makes a distinction between compression to spreading. It's the end of the communication as the frequency rises.

Imani stirs a cup of hot sencha tea with a cool silver spoon. She notices that the silver spoon becomes warmer. What energy change occurs when the silver spoon is added to the hot cup of sencha tea?
A. The spoon adds its cold to the hot tea
B. The hot tea absorbs the heat from the spoon
C. The cool spoon causes the water to expand thus cooling it
D. The tea loses heat to the spoon causing the spoon to become warmer
Answer:
D. The tea loses heat to the spoon causing the spoon to become warmer
Explanation:
When the silver spoon at a lower temperature than the tea, is added to the tea, it makes thermal contact. Hence, the heat transfer starts between the two until the equilibrium is reached. We know that the heat transfer takes place from the body with a higher temperature to a body with a lower temperature. As a result, the body with higher temperature loses heat and its temperature lowers down. While the body with a lower temperature gains heat and its temperature rises.
Therefore, the correct option is:
D. The tea loses heat to the spoon causing the spoon to become warmer

In the example of a hammer hitting a nail, which is hit harder? the nail, the hammer, or they both hit equally?
Answer:
both hit qaulity
Explanation:
Newton's Third Law says that every interaction involves two forces - in this case (1) hammer pushes nail, and (2) nail pushes hammer. When a hammer hits a nail, Newton's Third Law says that the force that the hammer exerts on the nail is exactly the same size as the force the nail exerts on the hammer.

Answer: I didnt understand it sorrryryyyyyyy
Explanation:
Explain one inference scientists made about the interior of the Earth based on seismic waves. Use the words S & P waves in your answer. Use the word refract/bend in your answer
Answer:
"An earthquake radiates P and S waves in all directions and the interaction of the P and S waves with Earth's surface and shallow structure produces surface waves. Near an earthquake the shaking is large and dominated by shear-waves and short-period surface waves." please rephrase this in your own words.

Suppose you needed to push a 1,500-N sofa up a frictionless ramp with a 30° angle. How much force would you have to apply to the sofa?Show your work below.
Answer:
1299N
Explanation:
GIven data
Weight W= 1500N
Angle Ф= 30°
The applied force up the frictionless ramp is gotten by applying the formula below
F= WcosФ
substitute
F=1500 cos 30
F = 1500*0.8660
F= 1299N
Hence the applied force is 1299N

the body acts on a force of 3N with the shoulder 20 cm. What is her moment?
Answer:
0.6Nm
Explanation
Given
Force = 3N
Distance = 20cm = 0.2m
Moment = Force * perpendicular distance
Substitute
Moment = 3N * 0.2
Moment = 0.6Nm
Hence her moment is 0.6Nm

100 cm cubic of water is mixed with 50 centimetres cubic of concentrated acid of density 1.2 gram per centimetre cube assuming no change in volume find the average density of the mixture the density of water is 1.0 gram per centimetre cube
Answer:
Average Density = 1.07 g/cm³
Explanation:
The average density of the whole mixture is given by the following formula:
[tex]Average\ Density = \frac{mass\ of\ whole\ mixture}{volume\ of\ whole\ mixture}[/tex]
where,
volume of whole mixture = volume of water + volume of acid
volume of whole mixture = 100 cm³ + 50 cm³ = 150cm³
mass of whole mixture = mass of water + mass of acid
mass of whole mixture = (volume of water)(density of water) + (volume of acid)(density of acid)
mass of whole mixture = (100 cm³)(1 g/cm³) + (50 cm³)(1.2 g/cm³)
mass of whole mixture = 160 g
Therefore,
[tex]Average\ Density = \frac{160\ g}{150\ cm^3}[/tex]
Average Density = 1.07 g/cm³
how does electricity work?
Answer:Electricity works by getting a bunch of conductor elements together and creating a flow of electron-stealing patterns through them. This flow is called a current. ... Once you can control the direction the electrons are going, you can use them to power or charge anything from a light bulb to your TV to your electric car.

A factory has 1200 workers of which 720 are male and the rast are female what percent of workers are female
Answer:
Percent of Female Workers = 40%
Explanation:
The percentage of the female workers in the given group of workers can be easily found by the following formula:
[tex]Percent\ of\ Female\ Workers = \frac{No.\ of\ Female\ Workers}{Total\ No.\ of\ Workers}\ x\ 100\%[/tex]
where,
Total No. of Workers = 1200
No. of Female Workers = Total Workers - No. of Male Workers
No. of Female Workers = 1200 - 720 = 480
Therefore,
[tex]Percent\ of\ Female\ Workers = \frac{480}{1200}\ x\ 100\%[/tex]
Percent of Female Workers = 40%

Help please:Calculate the mechanical energy of a bird flying at a speed of 10 m / s at an altitude of 15 m. If its mass is 150 g and the influence of gravitational force is 9.81 m / s²?
Mass of the bird(m) = 150 g = 0.15 kg
Speed (v) = 10 m/s
Kinetic Energy = [tex]\frac{1}{2}m v^{2} = \frac{1}{2} 0.15 (10)^{2}[/tex] = 7.5 J
Altitude (h) = 15 m
Gravitational Potential Energy = (0.15)(9.81)(15) = 22.0725 J
Mechanical Energy = Kinetic Energy + Potential Energy = 7.5 + 22.0725
= 29.5725 J
Qs 5 pleaseeee help!!!
Answer:
Ok, first is important that you understand how the heat radiation works.
All the objects that have some heat energy in them, radiate some of that energy in the form of electromagnetic waves.
Particularly, the Sun radiates a lot of energy (at the point that if you step under the sunlight, you can feel on your skin the heat that comes from the sun, this is due to radiation).
Now, suppose that you have a thin coat of water over you, then the material that gets impacted by that radiation will be the water and not you, and then the energy is dissipated (some of the energy goes to your body and some go to the air)
This is one way in which spraying water over themselves helps the elephants to keep them cool.
Another way in which heat can be transferred is by conduction.
When you have a hot object and a cool object, and you put them together (so the objects touch each other), the heat will flow from the hotter object to the cooler object until both objects have the same temperature.
Then if the elephant body temperature is larger than the temperature of the water that the elephant sprays over his body, when the water touches the body some of the heat in the elephant body will be transferred to the coat of water, and in this way, the temperature of the elephant's body decreases.
These are the two ways we wanted to find.
