Answer: Mahayana is a term for Buddhist culture. It is considered as existing branches of Buddhism.

Explanation:

The mahayanas is a major movement typically in the history of Buddhism. It was originated in Northern India. It comprises of many schools.  It involves the  reinterpretation of the fundamental human beliefs. This also involves the interpretation and teaching of Buddhism.

The three-level of perfection of Mahayana Buddhism are:

These three are mainly related to the virtuous practices for anyone, for a better and happy life in society. There are three more perfections those are-energy, meditation, and wisdom.

Mahanayan is a term under the Buddhist culture and is considered as the present or existing branch of Buddhism. It was originated in Nothern India, which comprises many schools.

The three main perfections state how the human being should live. The perfection of generosity is said as the entryway to dharma, it is the beginning of the aspiration to realize enlightenment for all beings. The perfection of morality guides us until we find our own balance, and the perfection of patience literally means "able to withstand."

Air. Plants are necessary for the creation of breathable air on Earth. During photosynthesis, plants convert carbon dioxide into oxygen and improve the air we breathe.

They can serve as food or as a cooling environment for astronauts traveling in space. Plants can help regulate cabin humidity by metabolizing atmospheric carbon dioxide to produce useful oxygen.

The crews of human spacecraft may experience psychological benefits from growing plants in space. The ISS could benefit from plant growth by producing oxygen for astronauts to breathe and removing carbon dioxide from the atmosphere.

According to the researchers' findings in their article, eating these fresh foods is also thought to have the additional advantages of reducing stress and boosting morale.

Answer:

There is no diagram in this question, however, the question can be answered based on general understanding.

1. current and voltage; direct relationship

2. current and resistance; inverse relationship

3. voltage and resistance; direct relationship

Explanation:

The relationship between current (I), resistance (R) and voltage (V) has been explained by Ohms in his law. In Ohms law, which states that the current flowing through a circuit is directly proportional to the voltage and inversely proportional to the resistance.

This further means that if the voltage (V) increases, then the current (I) also increases and vice versa while if the resistance (R) is increased, the current (I) decreases and vice versa.

The equation represented by this law is:

V = IR or I = V/R or R = V/I

Likewise, the when the resistance is increased, the voltage increases and vice versa.

Therefore;

- Current (I) is directly proportional to the Voltage (V)

- Current (I) is inversely proportional to the Resistance (R)

- Voltage (V) is directly proportional to the Resistance (R)

Answer:

I would say your answer is: The frequency of oscillations is 1 HZ { 1 cycle per second}.

The frequency of pendulum oscillations which is 0.25 m long is 1 HZ (1 cycle per second).

The quantity of waves leaving a spot in relation to time is known as its frequency. Hertz units are used to measure frequency. Humans with typical hearing abilities can hear frequencies between 20 Hz and 20 kHz. The frequency is defined mathematically as the time period divided by the factor of one. The number of rotations or vibrations that a body in periodic motion makes in a given amount of time.

A moving disturbance is referred to as a wave. The waves that must pass through a medium like air or water are referred to as mechanical waves. Other forms of waves, such as electromagnetic waves, can pass through both mediums and a vacuum.

Given:

The length of the pendulum, l = 0.25 m,

Calculate the frequency by following the formula:

f = [tex]1/T[/tex] =ω / 2[tex]\pi[/tex]

Therefore, the frequency of pendulum oscillations which is 0.25 m long is 1 HZ (1 cycle per second).

Explanation:

The contact forces, such as friction or the push force, are due to the fact that the electrons that are in one of the objects get close to electrons that are in the other object and since it has the same charge, intense repuesive forces are formed that objects move. We can see that in these forces the electrons are still attached to the material and only electoral repulsion is what creates the force.

In the previous explanation, it is valid for all types of material, the only change occurs due to the strength of the bond, in the case of materials with free electrons, such as metals, the forces are small, so the sliding occurs for small bourgeois

In insulating materials such as rubber where the electronons are tightly bound, closer proximity is needed to move the electrons from their equilibrium position.

Answer:

26.5m/s²

Explanation:

Given parameters:

Tangential velocity of the object  = 23m/s

Radius of track = 20m

Unknown:

Acceleration = ?

Solution:

The acceleration of the body is its centripetal acceleration. It is given by;

  a  = [tex]\frac{v^{2} }{r}[/tex]  

v is the tangential velocity

r is the

          a  = [tex]\frac{23^{2} }{20}[/tex]   = 26.5m/s²

Answer:

F = 845 [N]

Explanation:

To solve this problem we must use the following equation of kinematics.

[tex]v_{f} ^{2} =v_{o} ^{2} +2*a*x[/tex]

where:

Vf = final velocity = 26 [m/s]

Vo = initial velocity = 0

a = acceleration [m/s²]

x = distance = 2.8[m]

[tex]26^{2} = 0 +(2*a*2.8) \\5.6*a = 676\\a = 120.71[m/s^{2}][/tex]

Now we have to use Newton's second law which tells us that force is equal to the product of mass by acceleration.

ΣF = m*a

where:

F = force [N]

m = mass = 7 [kg]

a = acceleration = 120.71 [m/s²]

[tex]F = 7*120.71\\F = 845 [N][/tex]

Answer:

384N

Explanation:

Given parameters:

Mass  = 3kg

radius  = 0.5m

Speed  = 8m/s

Unknown:

Centripetal force  = ?

Solution:

The centripetal force is the inward force that keeps a body in motion along a circular path.

It is mathematically expressed as;

      F = [tex]\frac{mv^{2} }{r}[/tex]  

m is the mass

v is the speed

r is the radius

 Now insert the parameters and solve;

Radioactive contamination

Explanation:

When an unwanted material that contains radioactive atoms is present in another material is known as Radioactive contamination.

The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive. Alpha, beta, and gamma decay are three of the most prevalent forms of decay, and they all entail the emission of one or more particles.

According to the statement, "For a given time, the number of nuclei of the elements existing at that moment is exactly proportional to the rate of radioactive decay of an atom." This may be expressed as, where N is the total number of nuclei, d N d t N.

When radioactive particles are deposited on, inside of, or around an individual or a business, nuclear radiation results. When radioactive materials are discharged into the environment, they have the potential to contaminate the air, water, surfaces, soil, plants, buildings, people, and animals.

Explanation:

I recently took this test and this was the correct answer. Please like if this helped you! :)

The statement "Energy in an isolated system remains constant" is correct which is based on the law of conservation of energy option (D) is correct.

The law conservation of energy can be defined as the energy that cannot be created either it cannot be destroyed it only can change from one state to another state.

As we know, from the definition of the law of conservation of energy,

The energy that cannot be created either cannot be destroyed.

According to the rule of conservation of energy, the energy in an isolated system doesn't change.

Explanation:

You can work at 70 to 85 percent of your maximum heart rate during vigorous activity.

The Sun light is reflected back by earth. On process of reflecting back the sunlight, the lower layer of troposphere absorbs the most sunlight and upper layer absorbs the least sunlight. So when We ascend to troposphere, we move towards the upper layer of troposphere where sunlight is least absorbed and is colder than lower layer where sunlight is most absorbed

  In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.
