What is the mass of an object on the moon whose weight sitting on the Earth is 1900 N?

What are properties of what and there importance

kirill [66]

Answer:

Physical and chemical properties

Explanation:

There are different types of properties

Physical properties

The physical properties of matter are those characteristics specific to the substance, to be observed or measures do not produce new chemical species, for example:

Smell, color, taste, crystalline shape, temperature melting temperature, boiling temperature, density, viscosity, surface tension, vapor pressure, solubility, hardness, brightness, malleability, ductility, conductivity, etc.

Chemical properties

The chemical properties of matter are those which, when observed or measured, produce new chemical species, by

example: reactivity to oxygen, water or acid.

And these are classified as follows.

Properties that do not depend on the amount of substance considered are called intensive properties, such as melting temperature or density. The so-called extensive properties are those that depend on the amount of material substance, such as volume or mass.

Intensive properties are also called specific because they are characteristics that make it possible to differentiate one substance from another. Also, extensive properties are known as general properties because they are present in all kinds of substance and do not allow them to be differentiated from each other.

On the other hand, chemical properties are those whose measurement implies a change in composition, usually irreversible. Flammability or that a substance is easily oxidized are chemical properties.

Backpackers often use canisters of white gas to fuel a cooking stove's burner. If one canister contains 1.45 L of white gas, and

lorasvet [3.4K]

Answer: One canister contains 1.03 Kg of fuel,

Explanation:

The density is defined as the relation between the mass and the volume $p=\frac{m}{v}$

First of all you need to have the same units for volume and density, so:

For the volume,

$1.45 L * \frac{1.10*10^{-3}m^{3} }{1 L} = 1.45 *10^{-3} m^{3}$

For the density,

$p = 0.710\frac{g}{cm^{3} } *\frac{1cm^{3} }{1*10^{-6}m^{3} }*\frac{1 Kg}{1*10^{3}g } = 710\frac{Kg}{m^{3} }$

From the density equation we have $m=p*v$ , so:

$710\frac{Kg}{m^{3} } *1.45*10^{-3} m^{3} = 1.03Kg$

Joe noted that the temperature in his aquarium dropped overnight. He concluded that thermal energy moved from the aquarium to th

alukav5142 [94]

Answer:

validate

Explanation:

Law of Conservation of energy

According to the law of conservation of energy, energy of a body or a system gets transferred to another system as different energy. We cannot create energy nor we can destroy energy. Energy is always transformed into other forms of energy.

In the context, Joe noticed that the aquarium's temperature dropped during the night and he concluded that according to the law of conservation of energy, the energy of the aquarium in terms of thermal energy is being transferred to the surrounding air.

This is because the aquarium is considered to be an open system where energy can come in and move out.

Hence Joe's statement is valid.

An object is suspended from the ceiling with two wires that make an angle of 40° with the ceiling. The weight of the body is 150

MaRussiya [10]

Refer to the diagram shown below.

Let T = the tension in each wire.
For equilibrium,
2T cos(50°) = 150 N
1.2856T = 150
T = 116.677 N ≈ 117 N

Answer: 117 N
