The difference between mass and time is the influence of the earth's gravitational force on objects

<h3><em>Further explanation</em></h3>

In general, some people equate mass and weight.

Mass is one of the principal quantities, which is related to the matter in the matter, whereas weight is a force that leads to the center of the earth which is subject to the earth to matter (Earth's gravitational force)

So that the mass does not depend on the location of the object, while the weight can change depending on the position of the object

In international standards, the mass unit is kg while the weight is in units of newton

1 kg itself is the mass of a cylinder made of platinum-iridium

While the standard mass of an atom is determined according to the carbon-12 atomic mass of 12 atomic mass units

1 atomic mass unit comparable to 1.6605402.10-17 kg

Measuring the atomic mass using a mass spectrometer.

The mass itself can be measured by the arm balance while the weight is measured by the spring balance

One equation that can relate mass and force (weight) is

W = m.g

W = weight, N

m = mass, kg

g = gravity acceleration, m / s2

Actually mass and weight are two different things but most people did not understand the difference between them. And they are used synonymously on the earth. Mass is the measure of the amount of matter and weight is the measure of how the force of gravity acts on the mass that is Weight = mass x force of gravity. And they are also directly proportional to each other that is also the reason both terms are used synonymously.

Answer:

The correct matching of the air mass and the letters in the word bank are given as follows;

1. Warm and humid ↔ D

2. Extremely cold and dry ↔ B

3. Cold and dry ↔ A

4. Cold and humid ↔ C

5. Warm and dry ↔ E

Where;

A Represents continental polar

B Represents Artic

C Represents Maritime Polar

D Represents Maritime Tropical

E Represents Continental Tropical

Explanation:

A. A continental polar is one that can be described as a cold and dry climate as the region is located at a further away from the oceanic water bodies that add humidity to the climate

B. The regions of the Artic and the Antarctic have very limited amount of precipitation every year because the air is very cold as well as dry

C. A polar climate is a cold climate region, while a maritime climate is humid.

Therefore, the maritime polar climate combines both cold and humid conditions

D. A warm and humid region has high rainfall and humidity, as such the maritime climate which are humid and the tropical climate, which are warm, combine to give a warm and humid climate

E. The continental tropical climate can be described as warm and dry, compared to the continental water bodies, due to the location being distant from and therefore, the absence of high moisture containing wind that comes from the oceans.

A sample that contains only SrCO3 and BaCO3 weighs 0.800 g. When it is dissolved in excess acid, 0.211 g car- bon dioxide is lib

MrRissso [65]

Answer:

53.9%

Explanation:

1 mole of BaCO₃ yields 1 mole of CO₂,

1 mole of SrCO₃ yields 1 mole of CO₂

m₁ = mass of BaCO₃

m₂ = mass SrCO₃

molar mass of SrCO₃ = 147.63 g/mol

molar mass of BaCO₃ = 197.34 g/mol

molar mass of CO₂ = 44.01 g/mol

mole of CO₂ in 0.211 g = 0.211 g / 44.01 = 0.00479

mole of BaCO₃ = m₁ / 197.34

mole of SrCO₃ = m₂ / 147.63

mole of BaCO₃ + mole of SrCO₃ = 0.00479

(m₁ / 197.34) + (m₂ / 147.63) = 0.00479

147.63 m₁ + 197.34 m₂ = 139.55

m₁ + m₂ = 0.8

m₁ = 0.8 - m₂

147.63 (0.8 - m₂) + 197.34 m₂ = 139.55

118.104 - 147.63 m₂ + 197.34 m₂ = 139.55

49.71 m₂ = 139.55 - 118.104 = 21.446

m₂ = 21.446 / 49.71 = 0.431

the percentage of m₂ ( SrCO₃ ) in the sample = 0.431 / 0.8 = 0.539 × 100 = 53.9%

A wave of infrared light has a speed of 6 m/s and a wavelength of 12 m. What is the frequency of this wave?

andreev551 [17]

Answer: The frequency of the wave is 0.5 hertz.

Explanation:

$\nu =\frac{c}{\lambda }$

$\nu$ = Frequency of the wave

$c$ = speed of the light in m/s

$\lambda$ = Wavelength of the wave.

Here in question we are given with speed of the infrared light. So, we will replace the value of speed of light(c) from the given value of the speed of the infrared light.

Speed of infrared light = 6 m/s

$\nu =\frac{\text{speed of infrared light}}{\lambda }=\frac{6 m/s}{12 m}=0.5 hertz$

The frequency of the wave is 0.5 hertz.
