If a body p with a positive charge is placed in contact with a body q (initially uncharged), then the nature of charge gained by q must be positive, because rubbing an uncharged body with a charged body or placed in contact with a positive charged body, helps gain a charge to the uncharged body.
There are a variety of methods to charge an object. One method is known as induction. In the induction process, a charged object is brought near but not touched to a neutral conducting object.
Let's know, how a element gain positive charge?
A positive charge occurs when the number of protons exceeds the number of electrons. A positive charge may be created by adding protons to an atom or object with a neutral charge. A positive charge also can be created by removing electrons from a neutrally charged object.

Answer:
28852 J
Explanation:
When a force applied in a body produces a displacement in it, the force realized a work. The force that moves Karen is contrary to her weight and must be equal to it.
The work (W) is:
W = F.d.cos(θ), where F is the force, d is the displacement, and θ is the angle.
Knowing that cos(26°) = 0.899, and F = m*g
W = 51.9*9.8*63.1*0.899
W = 28852 J

That will be A melting a substance that's because the rest are examples of chemical changes and also its the same thing but in a different form.
Answer:
D. 3
Explanation:
First of all the mechanical advantage of a wedge is defined as the ratio of its slope length to its width.
Mathematically,
where,
IMA= Mechanical Advantage
L= slope length, and
w= width.
Given that,
slope length, L= 3.3 inches, and
width ,W= 1.1 inches
Then,
Mechanical Advantage, IMA
