What is one way that food is mechanically changed during the process of digestion

Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.

PLEASE HELP: A particle contains 25 protons and 23 electrons. What type of electric charge does the particle have?

Answers

Answer:In physics, a charged particle is a particle with an electric charge. It may be an ion, such as a molecule or atom with a surplus or deficit of electrons relative to protons. It can also be an electron or a proton, or another elementary particle, which are all believed to have the same charge (except antimatter).

A cart is set up as shown below, with three fans directed to the left and two of the fans running. The motion of the cart is represented by the v vs t graph shown. If the experiment were repeated with all three fans running, what might the resulting v vs t graph look like?

Answers

The force of 3 fans would be grater than the force of 2 fans.
So the cart would have greater acceleration to the right, and
it would reach a greater speed to the right. The resulting
'v' vs 't' graph would have a greater positive slope, and would
be higher at any given time.

You might get a better answer if you let us actually SEE the
picture and the graph.

The resulting

'v' vs 't' graph would have a greater positive slope, and would

be higher at any given time.

Gravity has traditionally been defined as a force of attraction between things that have

Answers

The gravity has traditionally been defined as a force of attraction between things that have masses.

Explanation:

Gravitational force is a type of attractive force. It is because of this force, that we are able to walk on this Earth. Also due to gravitational force, the solar system and the galaxies are existing in the universe. Sir Issac Newton first discovered this force. He postulated the universal law of gravity. And according to this law, the gravitational force will be acting between the objects having masses and separated by a distance. So in this law, it states that gravitational law is directly proportional to the product of masses and inversely proportional to the square of the distance between them.

Thus, the gravity has traditionally been defined as a force of attraction between things that have masses.
