What lens could get dirty with oil if you move the revolving nosepiece in the wrong direction after viewing under oil immersion?

From what we know, we can confirm that doing this may dirty and cause harm to your 40x lens.

<h3 /><h3>Why would this cause harm to your lens?</h3>

Oil immersion is a technique that can be quite handy when attempting to view hard-to-see specimens. However, This should be done only with lenses that are made specifically for this, so revolving the nosepiece in the wrong direction will expose the 40x lens to the oil, for which it is not designed, and may cause harm to the equipment.

Therefore, we can confirm that the 40x lens could get dirty with oil if you move the revolving nosepiece in the wrong direction after viewing it under oil immersion.

how does an airplane’s kinetic energy and potential energy change as it takes off and lands? How does this energy change relate
mojhsa [17]

Answer: As the airplane goes higher, the mechanical energy is changed into gravitational potential energy. While flying, some energy is lost through drag to thermal (heat) energy and sound energy. Some is also lost as the plane makes the air around it move. ... As speed and height decrease, kinetic and potential energy decrease.

All p block elements form ions.<br> True or False
FinnZ [79.3K]

Answer:

No this statement is false.

Explanation:

when an atom lose or gain the electron ions are formed. If the atom lose an electron the positive ions are formed called cations while anion is formed by the gaining of electron by an atom The elements having less electrons in valance shell usually lose their electrons while the elements like halogens having 7 valance electrons gain an electron to complete the octet. while p block elements noble gases are inert, their outer most valance shell is complete so they do not form ions.

P block elements are non-metals, metals and metalloids. These are thirty five elements. The P-block elements are present on right side of periodic table. There valance electrons are present in P orbital. The p-block metals are shiny and good conductor of heat and electricity. These metal lose the electron which is accept by non metals and form ionic bond. They have high melting points.

Metalloids includes boron, silicon, germanium, arsenic, antimony and tellurium. Metalloids contain both the properties of metals and non metals, Some metalloids are toxic like arsenic.

Most of p-block elements are non metals. They are bad conductor of heat and electricity and have low boiling points. The non metals mostly accept the electron from the metals and usually from ionic bond like in case of chlorine. It form the ionic compound with sodium.

The sodium chloride which is an ionic compound, formed by the complete transfer of electron from sodium to chlorine atom and form ionic bond. In this ionic compound sodium carry positive charge and chlorine carry negative charge there is attraction between these oppositely charged atoms.

3. A PS6 plugged into a 120 V outlet uses 3 Amps. What is the Resistance rating of
blondinia [14]

Answer:

R = 40 ohms

Explanation:

Given that,

The voltage of outlet, V = 120 V

Current flowing through the device, I = 3 A

We need to find the Resistance rating of  the power cord. Let the resistance is R. We know that,

Ohm's law, V = IR

Put all the values,

R=\dfrac{V}{I}\\\\R=\dfrac{120}{3}\\\\R=40\ \Omega

So, the resistance rating of the power cord is equal to 40 ohms.
