Answer:

The data are inadequate.

Explanation:

In the given question, there are fifteen players on the team.

But Diana and Kinsey survey only the five players on the starting lineup about their favorite mascot.

Based on only a few players out of the total number of players, both Diana and Kinsey can't choose a mascot for the basketball team.

So, the data are inadequate.

Hurry!!!!!!!!!!!!!!! Match the terms to the correct descriptions.
viva [34]

The type of energies or the words in this item are matched with the given descriptions. The lists below are as follow.<span>

<span>a. The word that best match this description is MECHANICAL energy. In most sources, mechanical energy is described to be that energy that is possessed by an object with respect to its motion and position. </span>

<span>b. The answer to this item is LIGHT energy. This type of energy can be created through different means (i.e. radiation, chemical, and mechanical). This is the energy emitted by hot objects such as the sun, lasers, and bulbs.</span>

<span>c. The type of energy that is transferred by the movement of the electrons through a conductor is ELECTRICAL energy. The movement of the electrons along the line is commonly called as the current. Moreover, this is also a type of kinetic energy because of the movement of the electrons. Thus, the faster the movement of the electron the higher is the energy. </span>

<span>d. The type of energy that is stored in batteries or food is CHEMICAL energy. This type of energy is that which is stored in the bonds of the different chemical compounds. This is also most commonly released when reaction between elements/compounds happen.</span>

<span>e. The energy that travels through vibrations and waves is SOUND energy. As given above, this is associated with the movement or vibrations of the matter. This is also a type of mechanical energy because of the waves produced through to the vibrations.</span>

<span>f. The type of energy that is found in the nucleus and atoms is the NUCLEAR energy.  Nuclear reactions most often released this type of energy simultaneous with the generation of heat. </span>

<span>g. The stored energy is called the POTENTIAL energy. The equation for this energy is mgh where h is the height, pertaining to the position of the object. Once the object is released, it will be converted to other forms of energy. </span>

<span>h. The answer to this item is THERMAL energy. This type of energy can be transferred in three different ways: (1) conduction, (2) convection, and (3) radiation.</span></span>

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring
ludmilkaskok [199]

Answer:

1.20 V

Explanation:

Pb(s) + Br_2(l)\rightarrow Pb^{2+}(aq) + 2Br^-(aq)

Here Pb undergoes oxidation by loss of electrons, thus act as anode. Bromine undergoes reduction by gain of electrons and thus act as cathode.

E^0=E^0_{cathode}- E^0_{anode}

Where both E^0 are standard reduction potentials.

Given,

Pb^{2+}(aq) + 2 e^-\rightarrow Pb(s)

E^0_{[Pb^{2+}/Pb]}= -0.13\ V

Br_2(l) + 2 e^-\rightarrow 2 Br(aq)

E^0_{[Br_2/Br^{-}]}=+1.07\ V

E^0=E^0_{[Br_2/Br^{-}]}- E^0_{[Pb^{2+}/Pb]}

E^0=+1.07- (-0.13)\ V=1.20\ V

During seafloor spreading, what kind of new earth forms?​
Elena-2011 [213]

Answer:

This bubbled-up magma is cooled by frigid seawater to form igneous rock. This rock (basalt) becomes a new part of Earth's crust. Seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor.
