An initially electrically neutral conducting sphere is placed on an insulating stand. A negatively-charged glass rod is brought

balu736 [363]

Answer: Option (c) is the correct answer

Explanation:

It is known that when a neutral object comes in contact with a charged object then an opposite charge develops on the neutral object. But this development of charge occurs only when both the objects come in contact and if they are not in contact with each other then there occurs no charge on the neutral object.

As in the given situation, negatively-charged glass rod is brought near, but does not touch the sphere. So, there will occur no charge on the sphere.

Thus, we can conclude that final charge on the sphere is neutral.

If a rod attached to the approaching charge if the rod consists of "stiff" spring-like bonds for which atoms undergo small oscil

Hoochie [10]

Answer: hello options related to your question is missing attached below is the missing part of your question

answer: No charge of the length of the bonds expected because the rod did not touch the charge source ( option A )

Explanation:

When the Charge is first, Furthest away and second and closest to the source charge. <em>The spring like bonds can be said to have No charge of the length of the bonds expected because the rod did not touch the charge source </em><em>when Furthest away the bond with charge will be less effective </em>

For a science, you must build a model of an aquiefier. What material would be best to use for where the water will accumulate?

aleksklad [387]

Answer is C.

Water-holding capacity is controlled primarily by soil texture, and amount of organic matter. Soils with small particles containing clay have a larger surface are than those larger sand particles, and a large surface area that allows to hold more water.

2.3mol of monatomic gas A initially has 4700J of thermal energy. It interacts with 2.6mol of monatomic gas B, which initially ha

rewona [7]

Answer:

Gas B has the higher initial temperature

6,199 J

7,008 J

Explanation:

Mathematically;

The thermal energy of a gas is given by:

E = 3/2 n kT

Where n is the number of moles, K is the molar gas constant and T is the temperature

For Gas A;

4700 = 1.5 * 2.3 * 8.31 * T

T = 4700/28.6695

Thus, T = 163.94 K

For gas B

8500 = 1.5 * 2.6 * 8.31 * T

T = 8500/32.409

T = 262.27 K

This means that gas B has a higher temperature than gas A.

At equilibrium, temperature

T = naTa + nbTb / (na + nb )

T = [2.3(163.94) + 2.6(262.27)]/(2.3 + 2.6)

T = [377.062 + 681.902]/4.9 = 216.12 K

216.12 K is the equilibrium temperature

= 216.12 K is the equilibrium temperature.

Thus, final thermal energy of Gas A and B

Gas A = 1.5 * 2.3 * 8.314 * 216.12= 6,199 J

Gas B = 1.5 * 2.6 * 8.314 * 216.12 = 7,008 J
