Explanation:

An atom consists of three subatomic particles. These are protons, electrons and neutrons.

A proton has a positive charge, an electron has a negative charge and a neutron has no charge.

A nucleus is the central part of an atom. And, inside the nucleus there are protons and neutrons. Whereas electrons move in circular path outside the nucleus.

Hence, we can conclude that most likely protons and neutrons are present in the nucleus of the atom.

A pharmaceutical company wants to test the efficiency of its new drug production techniques so they run 3 shifts of production f

spayn [35]

The percentage yield of the new production technique is 82.8%

<h3>What is the percentage yield?</h3>

Production is the procedure by which finished products are obtained form the raw materials. The production process involves the passing of raw materials through a certain procedure that involves the use of certain machines and equipment to give us the required products.

We are told in the question that there are three shifts;

Shift 1 produces 4562 grams

Shift 2 produces 5783 grams

Shift 3 produces 5247 grams

Average production from the three shifts = 4562 grams + 5783 grams + 5247 grams/3 = 5197 grams

The theoretical average yield is = 7000 grams + 7000 grams + 7000 grams/3 = 7000 grams

Now the percentage yield = actual yield/ theoretical yield * 100/1

percentage yield = 5197 grams/7000 grams * 100/1

percentage yield = 82.8%

Explain how transverse waves can be produced on a rope. Then describe how pieces of the rope move as waves pass.

andrew-mc [135]

Transverse waves can be produced on a rope by moving one end of the rope up and down.The movement causes motion in the particles that make up the rope and the rope itself becomes the medium. The particles move perpendicular to the propagation. The movement also causes crests(highest point of the wave) and troughs (lowest point of the wave) which move along the direction of propagation.
