A------turns about a fixed point called a fulcrum.

The dependent variable in Lauren's experiment is the growth of the African violets, and the independent variables are the locations of the plants. Other growth factors like watering, plant food, soil amount, and soil type should be controlled to ensure the experiment's accuracy.

In Lauren's situation with the African violets, the dependent variable is the growth or health of the plants, since it is what she is observing and measuring in response to the different conditions. The independent variables are the locations where the plants are placed (balcony, kitchen window, mantel in the living room), as these are the conditions that Lauren is changing to see how they affect the growth of the African violets.

To have a controlled experiment, Lauren should keep other factors constant that may affect plant growth, such as the amount of water (which she is already controlling), the amount of plant food, the amount of soil, and the type of soil.

If Lauren's experiment were setup like Gary's - with a focus on the amount of sunshine - she might control for things like individual plant variation, soil temperature due to different colors of containers, water loss due to evaporation from the soil, and the effect of insects which may attack one set of plants but not another.

Answer:

Maslow (1943, 1954) stated that people are motivated to achieve certain needs and that some needs take precedence over others. Our most basic need is for physical survival, and this will be the first thing that motivates our behavior. Once that level is fulfilled the next level up is what motivates us, and so on.

Explanation:

You would need oxygen because as your workout intensifies, your body needs more oxygen to be supplied to the muscles.

The correct answer is D. Exothermic

Explanation:

One of the features used to classify reactions is whether energy is released or absorbed during them. In this way, when the reaction causes energy to be absorbed this is classified as endothermic; an example of this is when an ice cube melts because it absorbs heat from the environment. On the other hand, if energy is released, the reaction is exothermic; for example, fire releases heat, and therefore this reaction is exothermic. According to this, it can be concluded not all reactions release energy but only exothermic reactions.

Answer:

Final speed of the stone, v = 35 m/s

Explanation:

It is given that,

Initial speed of the stone, u = 5.6 m/s

Let v is the velocity of the stone after 3 seconds have passed. It is moving down under the action of gravity. So, using the first equation of motion as :

[tex]v=u+at[/tex]

[tex]v=u+gt[/tex]

[tex]v=5.6+9.8\times 3[/tex]

v = 35 m/s

So, the final speed of the stone is 35 m/s. Hence, this is the required solution.

Answer

5m/s

Explanation:

Resultant is defined as the single velocity/forces that balances all other velocities/forces acting on a body. It is also defined as the vector sum of the vectors acting on a body.

Given two vectors in the x and y direction i.e Vx = 3m/s Vy = 4m/s

The formula of the resultant of both vectors will be;

R²= Vx² + Vy²

Where R is the resultant vector

R²= 3²+4²

R²=9+16

R²=25

R=√25

R=5m/s

Therefore, the magnitude of the resultant velocity is 5m/s

Centripetal acceleration is the acceleration of an object moving in a circle directed towards the center, as part of uniform circular motion.

Centripetal acceleration is the acceleration of an object moving in a circle, directed toward the center. It is always present in uniform circular motion, causing the object's velocity to constantly change direction.

Sarah needs to know also the direction of the airplane.

In fact, the velocity of an object is a vector, which means it has

a) a Magnitude (the speed)

b) a direction

Knowing the distance and the time, Sarah is only able to calculate the speed (which is the magnitude of the velocity), given by

[tex]v=\frac{distance}{time}[/tex]

but in order to give complete information about the velocity, she also needs to know the direction of the airplane.

The relationship between the Kelvin and Celsius temperature scales is given by: [tex]\( K = ^\circ C + 273.15 \)[/tex], where[tex]\( K \)[/tex] is the temperature in Kelvin and [tex]\( ^\circ C \[/tex]) is in Celsius.

The equation relating the Kelvin and Celsius temperature scales is [tex]\( K = ^\circ C + 273.15 \).[/tex] In this equation, [tex]\( K \)[/tex] represents the temperature in Kelvin, and [tex]\( ^\circ C \)[/tex] represents the temperature in Celsius. The addition of 273.15 to the Celsius temperature converts it to the equivalent temperature in Kelvin. This conversion is necessary because the Kelvin scale is an absolute temperature scale, starting from absolute zero, where molecular motion ceases entirely.

Conversely, to convert a temperature from Kelvin to Celsius, one subtracts 273.15. This relationship is crucial in various scientific and engineering applications where temperatures need to be expressed in different units. For instance, in physics and chemistry, Kelvin is often used in thermodynamic calculations, while Celsius is more commonly used in everyday contexts.

This relationship stems from the definition of the Kelvin scale, where 0 K is defined as absolute zero, the theoretical lowest temperature possible, and the Celsius scale, where 0°C is defined as the freezing point of water at standard atmospheric pressure, and 100°C is defined as the boiling point of water at standard atmospheric pressure. The offset of 273.15 accounts for the difference between the two scales' zero points.

Answer:D

Explanation:

Final answer:

The terms 'sentences' refer to the legal consequences imposed for committing a crime, including prison or jail time. Misdemeanors typically lead to shorter jail sentences, whereas felonies can result in longer incarceration in prison. Alternative sentencing options are also available, such as probation or rehabilitation.

Explanation:

Another name for prison or jail terms is sentences. A sentence is the formal legal consequence imposed by a court upon a person who is convicted of a crime. Misdemeanors are less serious crimes compared to felonies, and they often result in incarceration for one year or less, which typically occurs in a local jail rather than a state or federal prison. Felonies are more serious crimes and can lead to longer periods of incarceration in state or federal prisons. Alternative sentencing options, such as probation, rehabilitation, or home confinement, might also be used instead of jail time, particularly in the case of misdemeanors.

Prisons and jails serve different purposes; jails typically house individuals awaiting trial or serving short sentences, while prisons are for those serving longer sentences. The choice between sentencing someone to jail or prison often depends on the severity of their crime and the length of the sentence imposed.

Answer:

Electrons re deflected by both electrical and magnetic fields.

Explanation:

When an electron enters in magnetic field at any arbitrary angle Θ, the magnetic force experiences by electron is given by

[tex]F = q \times v\times B\times Sin\Theta[/tex]

So, electron experiences a force and deflects.

When an electron enters into electric field, the force experiences by the electron is given by

[tex]F = q \times E[/tex]

So, electron also experiences a force and deflects.

The color of the light after yellow light is a mixture of red and green light would heat a yellow brick the most is blue color.

Colored fire is a common pyrotechnic effect which is used in the stage productions, fireworks and also by the fire performers all over the world. Generally, the color of a flame may be red, orange, blue, yellow, or white colored, and it is dominated by the blackbody radiation from the soot and steam part.

A flame of light consists of different layers of light with different shades of colors. The inner core of the flame is blue in color which is the hottest part and the color changes to yellow, orange and red towards the center of the flame with decreasing the temperature of the fire.

Thus, the color of light which would the heat has as the yellow brick the most is blue color.

Answer:

The answer is: D. split-brain.

Explanation:

Although the absence of connection between hemispheres at the level of the corpus callosum does not imply a complete loss of functionality, this kind of disconnection between parts of the brain can give way to what is known as the callus disconnection syndrome.

This syndrome has been seen as patients with divided brain, that is, they have a disconnection between both hemispheres.
