Answer:

The same number of molecules, 6.0 × 10²³ molecules.

Explanation:

The amount of any given gas that can be stored in a container depends on the temperature, pressure and volume of the container. It does not depend on the nature (or identity) of the gas.

So if a 10-liter flask contains 6.0 × 10²³ molecules of hydrogen gas, it will contain the same amount of molecules of any other gas when temperature and pressure remain constant.

Answer:

Independent is x, which is the time.

Dependent is y, which is the distance.

Explanation:

The statement that could best explain how the offspring could inherit a trait not shown in the phenotypes of either parent would be that both parents are heterozygous for the red color.

Heterozygous parents can produce offspring with a phenotype that is distinctly different from that of either parent if the recessive alleles come together during random fusion of gametes.

Let us assume that the red color (R) in the New Hampshire chicken is the dominant one and the recessive one is the golden color (r). The genotype of the heterozygous parents would be Rr.

        Rr    x    Rr

     RR   Rr   Rr   rr

There is a probability (1/4) of producing a golden color chicken (rr), a trait that is not displayed in either of the parents.

Answer:

because the gravity of the ball can't go that high

There is a law called conservation of energy which states that energy can neither be created nor be destroyed. It can be only transferred from one form to another form. Therefore, some energy is lost  to the environment as sound or heat.

Energy transfer is a phenomenon in which energy transfer from one matter to another matter. Energy can be transferred in two forms that are by doing work or by transferring heat.

Heat can be transferred by three ways conduction, convention and radiation. In conduction, when two object are in direct contact, transfer of molecules takes place. As the ball impacted the ground, the energy would have been lost to the environment as sound or heat.

Therefore, some energy is lost  to the environment as sound or heat.

Option  D. Zn(s) → Zn2+(aq) + 2e and Ni2+(aq) + 2e → Ni(s)

The emf of a half-cell, with respect to the standard hydrogen electrode, is called the reduction potential. The emf for the Mg-Zn cell described would be: E=Eo(red) (Zn) - Eo(red) (Mg) = -0.76 - (-2.38) = 1.62V if the solutions are 1.0 M.

A half-cell reaction is either an oxidation reaction in which electrons are lost or a reduction reaction in which electrons are gained. The reactions occur in an electrochemical cell in which the electrons are lost at the anode through oxidation and consumed at the cathode where the reduction occurs.

Answer:1

Explanation:

Answer:

1800V

Explanation:

Given parameters:

Power in the resistor  = 180W

Current  = 0.1A

Unknown:

Potential difference  = ?

Solution:

The power in a circuit is given as:

         P = I V

P is the power

I is the current

V is the potential difference

  Now insert the parameters and solve for V;

       180  = 0.1 x V

           V  = 1800V

Answer:

D. Both are used by radio stations to transmit sound

Explanation:

The main difference between both modulations is that in frequency modulation, the frequency of the carrier wave is modified as per the transmit data, while in amplitude modulation, the carrier wave is modified according to the data. because of this it can NOT be A, B, or C but it CAN be D

Answer:

d. 671.6 nm

Explanation:

It is possible to solve the wavelength of a radiation from its frequency -or vice versa- using:

λ = c / f

Where λ is wavelength,

c is speed of light, a constant (2.998x10⁸m/s)

And f is frequency: 4.464x10¹⁴s⁻¹

Replacing:

λ = 2.998x10⁸m/s / 4.464x10¹⁴s⁻¹

λ = 6.716x10⁻⁷m

As 1m = 1x10⁹nm:

6.716x10⁻⁷m * (1x10⁹nm / 1m) = 671.6nm

Right answer is:

A is the reactant, B is the reaction process (or the name of the option that is hidden), C are the products, D is the coefficient, and E is the subscript.

a^2+b^2= (a+b)² -2ab

Answer:

Adding enough thermal energy to a substance can cause a change of state to occur. The change of state from a solid to a liquid is called melting. When energy is added to an ice cube, the ice particles speed up as energy is absorbed. When the particles move fast enough, the solid ice melts and becomes liquid water

Answer:

The fastest a planet moves is at perihelion (closest) and the slowest is at aphelion (farthest).

Explanation:

A planet travels fastest when the planet is closest to the sun also known as the perihelion.

An orbit is a regular, repeating path that one object in space takes around another one.

The planet moves faster when it is nearer the Sun and slower when it is farther from the Sun.

A planet moves with constantly changing speed as it moves about its orbit.

The fastest a planet moves are at perihelion (closest) and the slowest is at aphelion (farthest).

The force of gravity acting on a planet is equal to its mass times its centripetal acceleration.

Force of gravity = [tex]\frac{m v^2}{r}[/tex]

The force of gravity is defined by Newton's law of universal gravitation as:

Force of gravity = [tex]\frac{mMG}{r^2}[/tex]

Therefore:

[tex]\frac{mMG}{r^2}[/tex] = [tex]\frac{m v^2}{r}[/tex]

[tex]\frac{MG}{r}[/tex]= [tex]v^2[/tex]

According to the equation if v increases r decreases.  

Hence,  the planet is moving fastest when it's closest to the sun, also known as the perihelion.
