Mass = density • volume

so (12)(920)(kg/m^3•m^3)

11040 kg

Answer:

42g

Explanation:

the mass of a body is given by

m=weight/gravity

=420/10

=42

Answer:

The tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called inertia. This is why, the first law of motion is also known as the law of inertia.

Example.: A ball at rest on the ground continues to be at rest unless someone kicks it or any external force acts on it.

Answer:

The height of the wave is determined by the wind strength and fetch.

Explanation:

The height of the wave is determined by the wind strength and fetch.

The more the strength and the more the fetch size the more will be the height of the wave.

Remember as the wave approaches the coast its wavelength decreases and the wave height increases, whereas when the wave goes away from the coast its wavelength increases and height decreases.

Answer:

4g/cm^3

Explanation:

density = mass / volume

El término deporte engloba diversas formas de ejercicio, juegos y competiciones, que en su mayoría se relacionan con la actividad física de las personas. Así, los deportes más populares a nivel mundial son el fútbol, el baloncesto, el tenis, el rugby, etc.

Todos estos deportes, sin importar sus características, requieren de sus deportistas una serie de normas de conducta que hacen que los mismos sean cada vez mejores en sus respectivos deportes. Estas son, fundamentalmente, un buen entrenamiento, una correcta alimentación, un suficiente descanso y un seguimiento de las reglas del deporte.

La falta de alguna de estas 4 normas de conducta hace que el atleta no maximice su rendimiento, influyendo en forma negativa en sus resultados competitivos.

Answer:

6× 10¹⁰ metres

Explanation:

F=(G×M1×M2)/r²

(6.67×10¹⁶)=((6.67×10^-11)(6×10²⁴)(6×10²³))/r²

r²=3.6×10²¹

Therefore r=6×10¹⁰ metres

Archimedes’ principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, stating that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body.

Answer:

Yes

Explanation:

Answer:

The SI unit system defines 1N of force as the absolute unit of force necessary to provide a mass of 1kg with an acceleration of 1m/s2. Whereas the gravitational unit force is defined as the force experienced by a body of unit mass, that is 1kg, by the gravitation due to Earth. The unit of this force is Kgf

To calculate the density of a substance, its mass and volume has to be determined. So that:

i. For the milk in the carton, its mass and volume should be known.

ii. For the two objects given in the question, their individual masses and volumes have to be determined.

Density of a substance (ρ) is the rate of the mass (m) of the substance to its volume (V). It is measure in kg/[tex]m^{3}[/tex].

i.e ρ = [tex]\frac{m}{V}[/tex]

The density of a substance can be determined once the mass and its volume have been accurately measured.

1. How to measure the density of the contents of a milk carton.

a. Determine the mass of the milk carton with its content.

b. Determine the mass of the milk carton when empty.

c. Subtract the mass of the milk carton when empty from the mass of the carton with its content. This will give the mass of the milk in the carton.

d. Using a beaker, measure the volume of the milk.

e. Divide the mass of the milk by its volume to determine its density.

2. How to measure the densities of two objects of equal mass.

a. Fill an Eureka's can or a beaker with sprout with water to its brim.

b. Slowly drop the mass into the beaker with water so as to collect the volume of the liquid displaced into another beaker.

c. The volume of the liquid displaced is the volume of the mass.

d. Divide the mass of the object by its volume to determine its density.

NB: These procedures are observed to determine the densities of the two object individually.
