Atoms become charged by gaining or losing _____. electrons protons neutrons

Answers

Electrons

It's not neutrons because neutrons don't have a charge (they're not positive or negative). They don't make a difference in the charge of an atom.

It's not protons because atoms don't lose or gain protons. They stay in the nucleus.

Electrons, however, are not in the nucleus. They fly crazy fast around the nucleus and can sometimes get sucked in by the nucleus of another atom. Electrons are also negatively charged. Gaining electrons makes an atom negatively charged. Losing electrons makes an atom positively charged.

A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology.

It is called a Sea Stack.

This would be an illustration of Newton's first law of motion. Law of inertia, an object moving at constant velocity will keep moving at constant velocity until a force is acted upon it. Inertia is the tendency of an object to keep moving in a particular direction resisting to change, unless a force acts upon the object.

How does Coulomb's law relate to test charges?

Answers

Coulomb's law relate to test charges whenever the positive charge and the negative charge are placed 1 meters apart inside a vacuum made of air. The force of repulsion between the positive and negative charges are around 9.0x10E9 N.

a stone falls from a ledge and takes 8 seconds to hit the ground. The stone has an original velocity of 0 m/s. How tall is the ledge

Answers

The height of a falling object, h, in terms of the seconds passed, t, is
h = 0.5(-9.8t^2) + v_0t + h_0
0 = -4.9(8)^2 + 0 + h_0
h_0 = 64 * 4.9
= 313.6 meters

Here's a formula that tells the distance covered by an
accelerating object starting from rest. The formula is
very useful, and it's simple enough to memorize:

   Distance = (1/2) (acceleration) (time squared) .

If the object is falling, then the acceleration is gravity, 9.8 m/s²,
and the distance is

   (4.9) (time²) .

In this question,

   D = (4.9) (8²)

   = (4.9 x 64) = 313.6 meters.

Coupla comments:

-- This calculation ignores air resistance.
    We kind of ALWAYS do that, otherwise
    the calculation would be very complicated,
and would need a lot of other numbers
    that we don't know, like the size and shape
    of the falling object, and the density of the air.

Static charge develops on a substance as it acquires or loses protons due to friction. a. True
b. False

Answers

True because once it builds up enough + or - charges

Final answer:

False. The occurrence of a static charge on a substance is due to the gain or loss of electrons, not protons. This electron transfer occurs mostly when friction is between two different materials, leading to the creation of static electricity. Protons, being part of the atomic nucleus, stay stable and do not move, unlike electrons.

Explanation:

The statement given in the question is False.

Static charge develops on a substance when it gains or loses electrons, not protons. In fact, when friction is involved between two different materials, electrons get transferred from one material to another.

The one that gains electrons becomes negatively charged, while the one that loses electrons becomes positively charged. This is the principle behind the creation of static electricity. The protons in an atom are part of the atomic nucleus and they remain stable and don't move around, unlike electrons, which can move freely and transfer from one atom to another.
