Characteristics, such as field name and data type are properties that define a field.

<h3>What are the properties of a given discipline or research field?</h3>

The properties of a given discipline or research field are those that characterize the use of a particular type of information within the range of the attained field.

For example, genomics is a field characterized to make use of sequencing data, which refers to the linear order of nucleotides in the DNA sequence to provide useful information about the gene content and the presence of regulatory non-coding sequences.

Therefore, with this data, we can see that the properties of a given discipline or research field are mainly associated with the type of information that such discipline uses to make predictions in a given research and they are also related to the outcomes we can expect from such data.

A snow ball is thrown upward at a speed of 27 m/s. How high is the snow ball 3.5 seconds later? Also, how fast is it moving at t

JulijaS [17]

Answer:

Dy = 111.66 [m]

t = 3.5 [s]

Explanation:

To solve this problem we must use the equations of kinematics.

$v_{f} = v_{o} - (g*t)\\$

where:

Vf = final velocity [m/s]

Vo = initial velocity = 27 [m/s]

g = gravity acceleration = 9.81 [m/s²]

t = time = 3.5 [s]

Note: The negative sign of the equation means that the gravity acceleration goes in opposite direction

Vf = 27 - (9,81*3,5)

Vf = - 7.33 [m/s] (this negative sign indicates that at this moment the snowball is going downwards)

To find how high the snowball was we must use the following equation:

$Dy=v_{o} *t+\frac{1}{2}*g*t$

Dy = (27*3.5) + (0.5*9.81*3.5)

Dy = 94.5 + (17.16)

Dy = 111.66 [m]

A single slit is illuminated by light of wavelengths λa and λb, chosen so that the first diffraction minimum of the λa component

agasfer [191]

Answer:

λ_A = 700 nm , m_B = m_a 2

Explanation:

The expression that describes the diffraction phenomenon is

a sin θ = m λ

where a is the width of the slit, lam the wavelength and m an integer that writes the order of diffraction

a) They tell us that now lal_ A m = 1

a sin θ = λ_A

coincidentally_be m = 2

a sin θ = m λ_b

as the two match we can match

λ _A = 2 λ _B

λ_A = 2 350 nm

λ_A = 700 nm

For lam_B

a sin λ_A = m_B λ_B

For lam_A

a sin θ_A = m_ λ_ A

to match they must have the same angle, so we can equal

m_B λ_B = m_A λ_A

m_B = m_A λ_A / λ_B

m_b = m_a 700/350

m_B = m_a 2

Which of the following statements is/are true? Check all that apply. Check all that apply. The work done by a nonconservative fo

navik [9.2K]

Answer:

The work done by a nonconservative force depends on the path taken. TRUE

A nonconservative force permits a two-way conversion between kinetic and potential energies. TRUE

A potential energy function can be specified for a nonconservative force.

FALSE

The work done by a conservative force depends on the path taken.

FALSE

A conservative force permits a two-way conversion between kinetic and potential energies.

FALSE

A potential energy function can be specified for a conservative force.

TRUE

Explanation:

The work done by a nonconservative force depends on the path taken. TRUE

This kind of force can not be obtained from potential function so the work made by this kind of force depend of the path taken.

A nonconservative force permits a two-way conversion between kinetic and potential energies. TRUE

A nonconservative force permits conversion to kinetic energy plus potential energy during it made work over the system.

A potential energy function can be specified for a nonconservative force.

FALSE

Considering that the work made by kind of force depend of the taken path they can not be determined by a potential fuction.

The work done by a conservative force depends on the path taken.

FALSE

This asseveration is related with the previous one. So the conservative force can be deducted from a potential function thus their y work made do not depend of the path taken.

A conservative force permits a two-way conversion between kinetic and potential energies.

FALSE

This means that as conservative force is related from a potential function it only can modify the potential energy of the system.

A potential energy function can be specified for a conservative force.

TRUE

This is as consequence of the definition of conservative force that it can be determined from a potential function.

This model shows a ball being shot from the cannon. Which of these statements accurately describes the energy of the cannonball?

Fudgin [204]

The potential energy of the model will be the greatest at point C while it will be the least at point E. Option B and D are correct.

<h3>What is potential energy?</h3>

The potential energy of an object is due to its position. It can be given as the formula,

$U = mgh$

Where,

$U$ - potential energy

$m$ - mass

$g$ - gravitation acceleration

$h$ - height

From the formula since the mass and gravitation acceleration is constant, the potential energy of the model will depend upon the height only.

The potential energy will be greatest at point C because the relative position of the ball is the highest from the earth.

The potential energy will be lowest at point E because the height of the ball is the least in this position.

Therefore, the potential energy of the model will be the greatest at point C while it will be the least at point E.
