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

<h3>Further explanation</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.

Which of the following is not equal to 485 L?

ELEN [110]

Answer:

$4.85 * 10^4\ mL$

Explanation:

Given

485 L

Required

Determine the measurement not equal to 485L

$0.485\ kL$

From standard unit of conversion;

1 KL = 1000 L

Multiply both sides by 485

$485 * 1 KL = 485 * 1000 L$

$485KL = 485000L$

Divide both sides by 1000

$\frac{485KL}{1000} = \frac{485000L}{1000}$

$0.485KL = 485L$ ---- This is equivalent

---------------------------------------------------------------------------------------------

$4.85 * 10^4\ mL$

From standard unit of conversion;

1000 mL = 1 L

Multiply both sides by 485

$485 * 1000 mL = 1 L * 485$

$485000\ mL = 485\ L$

Convert to standard form

$4.85 * 10^5\ mL = 485\ L$

Hence; $4.85 * 10^4\ mL$ is not equivalent to 485L

---------------------------------------------------------------------------------------------

$48500 \ cL$

From standard unit of conversion;

100 cL = 1 L

Multiply both sides by 485

$485 * 100 cL = 1 L * 485$

$48500\ cL = 485\ L$

Convert to standard form

$4.85 * 10^4\ cL = 485\ L$ ---- This is equivalent

---------------------------------------------------------------------------------------------

$4.85 * 10^8 \$ μL

From standard unit of conversion;

1000000 μL = 1 L

Multiply both sides by 485

$485 * 1000000uL = 1 L * 485$

$485000000uL = 485\ L$

Convert to standard form

$4.85 * 10^8\ uL = 485\ L$ ---- This is equivalent

From the list of given options;

$4.85 * 10^4\ mL$ is not equivalent to 485L

When comparing the two elements K and Ge , the more metallic element is__________ based on periodic trends alone.

Inessa [10]

Answer:

Option D and Option B

When comparing the two elements K and Ge , the more metallic element is_____K_____ based on periodic trends alone.

When comparing the two elements Sb and Pb , the more metallic element is_____Pb______ based on periodic

Explanation:

The metallic characteristic increases when we move down a column in a periodic table or when we move left in the row.

Potassium and Germanium are located on the same row, but germanium lies on the right side of potassium. Thus, potassium (K) is more metallic than Germanium (Ge)

While Lead (Pb) lies to left of Sb in the adjacent column and is also lies below Sb. Hence Pb is more metallic than Sb

Why are aldehydes more reactive than ketones?

Simora [160]

Answer:

Aldehydes are typically more reactive than ketones due to the following factors. ... The carbonyl carbon in aldehydes generally has more partial positive charge than in ketones due to the electron-donating nature of alkyl groups. Aldehydes only have one e- donor group while ketones have two.
