1. Which of the following best describes a neutral solid object that is charged by conduction? The electrons in the neutral solid object relocate when a charged object is brought near.
The protons in the neutral solid object relocate when a charge object is brought near.
The electrons in the neutral object transfer onto a positively charged object.
The protons in the neutral object transfer onto a negatively charged object.

C: The electrons in the neutral object transfer onto a positively charged object.

Explanation:

In conduction, when we charge one object with another, both of them will now have the same type of charge. Thus, in conduction, a positive object is used to charge a neutral object, then it means that both objects become charged positively charged. Electrons are positive charges.

Thus electrons in the neutral object are transferred onto a positively charged object and so option C is right.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

50 inches should be the resultant vector
