Net energy is the amount of that is actually useable from an energy resource. Net-energy ratio is the ratio of the amount of useable energy from a resource and the amount it takes to make that energy useful. ... An energy source with high energy efficiency provides a lot of work for the amount of energy used.
<u>Answer:</u>
<em>The dissolved gases produce violent eruption as they escape.
</em>
<u>Explanation:</u>
Magma contains dissolved gases and these dissolved gases induce vapor <em>pressure on the magma.</em> The magma is able to remain in the dissolved state itself without erupting because this vapor pressure is less than the confining pressure of the <em>rock surrounding the magma. </em>
One the vapor pressure exceeds this confining pressure the dissolved gases begin to expand and<em> forms small gas bubbles</em>.
The <em>density of these gas bubbles</em> called vesicles is less than the density of magma and thus naturally tries to push out. When the gas bubbles escape the magma is also pushed out. Thus greater <em>amount of dissolved gases result in violent eruptions.

Answer:
Object B has more charge than Object A
Explanation:
Generally, unlike charges attract each other and like charges repel each other but it happens in a very rare case when like charges attract each other. It is so due to charge difference between the objects.
In the given example a positively charged ball moves towards positively charged object B because object B has more charge than object A and the ball. Due to large difference in the charges between two positive charges, positive charges are displaced at opposite end and object B get concentrated with negative charges that allows ball to move towards Object B.
Hence, the correct answer is "Object B has more charge than Object A".
1.limiting factor is a variable of a system that, causes a noticeable change in output or another measure of a type of system
2. Examples of limiting factors include competition, parasitism, predation, disease, abnormal weather patterns, natural calamities, seasonal cycles and human activities. In terms of population growth, limiting factors can be classified into density-dependent factors and density-independent factors.
3. When organisms face limiting factors, they show logistic growth.Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity
