The ball was kicked in the air and it iss about to hit the . if horizonta componenet of its final velocity is 10m/s and vertical component of its final velocity is -10m/s .what is the magnotide of th final vellocity of the ball?
Answers
Answer:
The total velocity of the ball will be 14.14 m/s.
Explanation:
Horizontal Velocity component = 10 m/s
Vertical Velocity component = -10 m/s
Total velocity of the ball will be found from the following equation:
(Total velocity) ^2 = (Horizontal Velocity) ^2 + (Vertical Velocity) ^2
Total Velocity ^2 = 10^2 + (-10)^2
Total Velocity^2 = 100 + 100
Total Velocity =
Total Velocity = 14.14 m/s

Answer:
mass
Explanation:
The density of a substance is defined as the ratio of mass of the substance to the volume of the substance.
It is a scalar quantity.
Its SI unit is kg/m^3.
By comparing the densities we get the idea about how dense the substance is.
For example, cotton and iron, the density of cotton is much less than iron so the cotton is less dense than iron.
The relative density is defined as the ratio of density of substance to the density of water at 4 degree C.
The density of water is maximum at 4 degree C.
Final answer:
Density is the mass per unit volume.
Explanation:
Density is a physical property of matter that describes the mass of a substance per unit volume. It is typically expressed in units like grams per cubic centimeter or kilograms per cubic meter. Density helps identify and compare substances, as objects with higher density are heavier for a given volume, while less dense substances are lighter.
Density is the mass per unit volume of a substance or object, defined as p = m/V. The SI unit of density is kg/m³. For many situations, grams per cubic centimeter (g/cm³) are used for the densities of solids and liquids, and grams per liter (g/L) are used for gases.

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.
