Answer:

         F = 3 fo

Explanation:

The electric force is given by Coulomb's law

         F = k q₁ q₂ / r²

where k is the Coulomb constant and is equal to 8.99 109  

with the initial charge the force is  

        Fo = k q₁ q₂ / r²  

        Fo =k q₁ q₂ / r²

In this case it is indicated that charge 1 is changed by the lithium atom a = 3 P  

we substitute  

        F = k 3p p / r²      

        F = 3 (k p² / r²)  

        F = 3 fo

 

we see that the charge increases by three orders of magnitude

what do scientific models predict will happen to Earths oceans if current trends continue unmitigated?
Margaret [11]

Answer:

I think that the answer is "Coral bleaching will continue to harm aquatic organisms.

Explanation:

Global warming causes the ocean temperatures to rise and also its pH to decrease due to increased dissolved carbon dioxide in the waters.

Due to the unfavorable temperatures and pH, the algae dissociate from the symbiotic relationship with coral polyps (as a survival mechanism) hence leaving the coral white (coral bleaching).

The symbiotic relationship is key for the survival of the coral polyps hence most die following the dissociation.

This upsets the reef ecosystem and affects all aquatic organisms that depend on the reef.

A loop rests in the plane of a page of textbook while a magnetic field is directed into the page. A clockwise current is induced
Sunny_sXe [5.5K]

Answer:

When the magnetic field is tilted so it is no longer perpendicular to the page.

When the magnetic field gets stronger.

When the size of the loop decreases.

Explanation:

According to the Faraday-Lenz law, the change of the magnetic flux over time causes an induced current, this flux is given by:

\Phi_B=BScos\theta

Therefore, there will be a variable magnetic flux, when the magnitude of the magnetic field (B) changes over time, when the area of the loop (S) changes over time and / or when the angle (\theta) between the field and the surface vector changes over time.

How much energy will it take to increase the temperature of 200 milliliters if water by 12 degrees Celsius?
AleksandrR [38]

Answer: The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C. Lead will warm up and cool down fastest because it doesn't take much energy to change its temperature.
