Mass = that which causes and object to have inertia

Newton’s First Law= a special case of Galileo’s Law of Inertia

Impulse= force multiplied by time

Momentum= velocity multiplied by mass

Velocity= momentum/mass

Newton’s Second Law= the acceleration of a mass directly proportional to the force acting on it

The pH scale for acidity is defined by pH=−log10[H⁺] where [H⁺]is the concentration of hydrogen ions measured in moles per liter
masha68 [24]

Answer:

5.62 * 10^-13 moles per liter

Explanation:

The pH of a solution is the negative logarithm to base 10 of the concentration of hydrogen ions. What we simply do here is to input the information in the question into the equation:

pH=−log10[H⁺]

Here we know the pH but we do not know the concentration of the hydrogen ions.

12.25 = -log [H+]

log[H+] = -12.25

[H+] = 10^-12.25

[H+] = 5.62 * 10^-13 moles per liter

Which of the following is the best definition of matter?
creativ13 [48]

Answer:

4.Anything that has mass

Explanation:

In order to appreciate what matter is, we must first know that matter is the 'stuff' that makes up the universe. Everything in the universe is composed of matter. Matter in turn is made up of atoms. Intact mass is the quantity of matter in a body.

All matter must have mass and occupy space. Hence all matter must have a measurable mass. This is a fundamental property of all matter. Hence every object in the universe has mass because it is composed of matter. We find matter in our plates, spoons , clothes and indeed everything we see in the universe! For instance, you can measure the mass of a spoon because it is made of matter which has mass and occupy space.
