What is the largest particle size that a stream can transport at a velocity of 5 centimeters per second?

Answer:

Velocity is a measure of both speed and direction of motion. Velocity is a vector, which is a measurement that includes both size and direction. Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction.

Explanation:

Scientists occasionally gather data that deviates from conventional ideas or interpretations. The widely held idea that the new information contradicts will frequently be revised or changed to take into account the new information if it is repeatedly verified.

Empirical evidence is the foundation of scientific knowledge. It is strong and lasting since it is the end product of all the prior study and testing that was done. But science also acknowledges that all of this information is a product of human endeavor and that it may contain numerous errors. Therefore, once a new idea is discovered and repeatedly confirmed, scientific knowledge is adaptable enough to take it into account and evolve.

Answer:

You decide to drop two different objects from a tall building and discover that one of the objects lands on the ground five seconds before the other object. What can you conclude? Newton's second law is not valid because each object should experience the same force of gravity and therefore should land at the same time.

Light

Explanation:

Light is the form of energy which enables us to see any object.

Okay, let's think this through step-by-step:

* The rate of energy transfer is 50 J/s

* We need to calculate the energy transferred in 4 seconds

* So we would calculate:

Energy in 4 seconds = Rate x Time

= 50 J/s x 4 s

= 200 J

So the heat energy produced within 4 seconds with an energy transfer rate of 50 J/s is 200 J.

The total amount of liquid will still be 100 milliliters.

Milliliters (mL) is a unit of volume measurement that is equal to the volume of a cube that is 1 cm on each side. It is commonly used to measure liquids, such as milk, juice, or medicine. Milliliters can also be used to measure dry ingredients, such as flour or sugar. One milliliter is equal to 0.001 liters, or about 0.034 fluid ounces.

For 100 milliliters of juice, you would need 100 milliliters of fruit juice. In other words, the amount of fruit juice required to make 100 milliliters of juice is the same as the amount of juice you are starting with. This is because when you mix fruit juice with water, the total amount of liquid remains the same. So if you start with 100 milliliters of juice and then add 100 milliliters of water, the total amount of liquid will still be 100 milliliters.

Blood travels throughout the body as follows:

Circulation is the continuous movement of blood throughout the body by the circulatory system. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart acts as a pump, sending oxygen-rich blood through the arteries to the body's cells, and then returning oxygen-depleted blood through the veins back to the heart.

The exchange of oxygen, nutrients, and waste products between the blood and cells occurs through the capillaries. This continuous flow of blood helps to maintain the body's functions and overall health.

Explanation:

Fourteen yard (14) yard

The average speed of the car is 35.6m/s

The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is represented by the magnitude and does not have direction. It is measured in meter per second

Therefore average speed = total distance / total time taken

The total distance here is 500+ 500= 1000km = 1×10⁶m

the time taken for the first journey = 500×1000/35= 14285.71 seconds

the time taken for traveling back = 500000/43= 11627.91 seconds

total time taken = 14285.71 + 11627.91 = 25913.62seconds

therefore average speed = 1000000/25913.62

A network of nerves known as the sympathetic nervous system aids in the body's "fight-or-flight" reaction. When you're under stress, in danger, or engaged in physical exercise, this system becomes more active.

increases in heart rate, blood pressure, breathing rate, and pupil size are caused by this area of the neurological system. Additionally, it results in blood vessels narrowing and a decrease in digestive juices.

The sympathetic nervous system is a portion of the nervous system that is responsible for producing reflex cardiovascular system alterations as well as localized adjustments (such sweating in reaction to a rise in body temperature).

Along with its opposite, the parasympathetic nervous system, the sympathetic nervous system is a component of the autonomic nervous system. The thoracic and lumbar spinal cord segments, collectively referred to as the thoracolumbar division, are where the sympathetic nervous system originates (T1 to L2,3).

A 70 kg person does a bungee jump from a bridge and falls straight down. The y-component of acceleration of the jumper is 1.6 m/s².

Given that,

Spring constant k is 80 N/m

Natural length of the bungee cord is 20 m

Total length of the bungee cord is 25 m

From Newton's second law of motion we know that, F = ma

By drawing a free body diagram we get,

Fe - W = m*a

where, Fe is elastic force, it can be written as k*Δx

k is the spring constant

Δx is the change in length of the cord

W is weight of the body acting downwards (mg)

Fe - W = m*a

k Δx - mg = ma

a = k/m (Δx) - g

a = k/m (x₁-x₀) - g

a = 80/70 (25-20) - 9.8

a = 11.43 - 9.8 = 1.6 m/s²

The following two reasons are why semiconductors must be present in a solar cell:

A. Semiconductors provide an avenue for the electrons that the photoelectric effect releases.

C. Semiconductors provide the electrons needed to create an electrical current.

When a substance absorbs electromagnetic radiation, a process known as the photoelectric effect causes electrically charged particles to be discharged from or inside the material.

When a transistor is confronted with light, it absorbs the electricity and transmits it to the substance. This causes energy to reach the negatively charged electron, allowing the particle to flow as an electric current through the substance.

Consequently, the answer is A. Semiconductors provide a route for the electrons which are emitted as a result of the photoelectric effect.

C. Semiconductors provide the electrons needed to create an electrical current.

The two statements that describe reasons why semiconductors must be included in a solar cell are:

B. They provide a path through which released electrons move to form an electric current.

D. They provide a source of electrons to be released by the photoelectric effect.

Semiconductors play a crucial role in solar cells. When sunlight strikes the semiconductor material, it excites electrons, allowing them to be released and flow as an electric current. This process is known as the photoelectric effect. The semiconductor acts as a pathway for these released electrons, allowing them to move and create an electric current. Therefore, options B and D accurately describe the roles of semiconductors in a solar cell.

The chi-square test assumes that the variables being analyzed are measured at a nominal or ordinal level of measurement.

In statistics, the level of measurement refers to the nature and properties of the data being collected. There are four levels of measurement: nominal, ordinal, interval, and ratio. Nominal and ordinal levels are considered categorical, while interval and ratio levels are considered numerical. The chi-square test is specifically designed for analyzing categorical data, where the observations can be classified into distinct categories or groups. It is used to determine whether there is a significant association or relationship between two categorical variables.

The test calculates the difference between the observed frequencies and the expected frequencies under the assumption of independence between the variables. It compares the observed and expected frequencies using a chi-square statistic and determines the p-value to assess the statistical significance of the association. Therefore, the chi-square test assumes that the variables being analyzed are measured at a nominal or ordinal level because it deals with categorical data and evaluates the relationship between different categories or groups.
