The table contains the planets in our solar system in order of their average distance from the Sun and their corresponding diameters. The first step in creating a model of the solar system is to scale these large diameters into smaller, more manageable numbers. Eventually, we’ll represent these numbers using circles drawn on paper. MercuryVenusEarthMarsJupiterSaturnUranusNeptune Diameter (km)487912,10412,7566792142,984120,53651,11849,528 Scaled Diameter (cm) 3.51.9 The ratio between Earth’s actual diameter and its scaled diameter can be used to find the scaled diameter of the other planets. Earth’s diameter of 12,756 kilometers is scaled to 3.5 centimeters as shown in the table. Now let’s find the scaled diameter of Mars as an example. Using the calculations shown, Mars’s diameter of 6,792 would be scaled to 1.9 centimeters. d × 12,756 = 6,792 × 3.5 d = 1.9 cm Use this same process to complete the table with the scaled diameters of the other planets. Round each answer to the tenths place. If you need additional math help, visit the Proportions section of the Math Review.

Answer:

1.Cells are the basic structural unit of all living organisms.

Answer:

It has three main parts:

1. All living things are made up of cells.

2. Cells are the basic building blocks of life.

3. All cells come from preexisting cells created through the process of cell division.

Explanation:

As science evolved, three more components were added to the theory. Some biology classes don’t require you to know these parts of the cell theory because they weren’t part of the original definition, but it’s still useful to be aware of them:

4. Energy flow occurs within cells.

5. Hereditary information is passed from cell to cell.

6. All cells have the same basic chemical composition.

So what does the cell theory actually mean? Let’s break it down. The first part of the cell theory states that all living things are made up of cells. Anything that’s alive, from bacteria to plants to humans, is composed of cells. And what are cells? The literal definition is a cell is a group of organelles surrounded by a thin membrane.

The cell theory definition states that cells are the building blocks of life. Cells both make up all living things and run the processes needed for life. Your hair, skin, organs, etc. are all made up of cells. In fact, each person is estimated to be made up of nearly 40 trillion cells! Each part of a cell has a different function, and your cells are responsible for taking in nutrients, turning nutrients into energy, removing waste, and more. Basically, everything your body does, it does because cells are directing the actionThe third part of the cell theory definition states that all cells come from preexisting cells. This means that cells don’t just appear out of thin air (known as “spontaneous generation”). New cells are always made from current cells. This means that all current life on the planet is descended from the very first cells, which first made an appearance on Earth roughly 3.5 billion years ago. Cells have been replicating themselves continuously ever since.

And what does the newer part of the cell theory state? Part four refers to the fact that, in all living cells, energy is continuously transformed from one type to another. Examples of these processes include photosynthesis (where plant cells convert light energy into chemical energy) and cellular respiration (where both plant and animal cells convert glucose into energy). Part five refers to DNA and the fact it is passed from parent cell to child cell. Finally, part six of the cell theory tells us that all cells are made up of the same chemicals: water, inorganic ions, and organic molecules.!

Computers are widely used for modeling weather systems because because weather systems are too complicated to be accurately predicted using small-scale. Hence option A is correct.

Weather refers to the condition of the atmosphere and includes terms like how hot or cold, wet or dry, quiet or stormy, clear or foggy, etc. The troposphere, which is the lowest part of Earth's atmosphere and lies just below the stratosphere, is where most meteorological events take place. Climate is the phrase for the average of atmospheric conditions over longer periods of time, whereas weather is the term for day-to-day temperature, precipitation, and other atmospheric factors. Without more explanation, "weather" is typically taken to refer to the weather on Earth.

Differences in air pressure, temperature, and moisture from one location to another influence the weather. The Sun's angle at any given location, which changes with latitude, may be the cause of these variations.

Hence option A is correct.

The answer is two meter per second square

Answer:

Explanation:

Because between this force the opposite direction will be zero

Answer: The answer is actually A, 20 N south

Explanation:

Because I got it wrong, but then it showed me the answer.

I'm going to assume you mean

[tex]y = 14t^2 - \dfrac{t^2}{2+5t} - 3[/tex]

Taking the derivative with respect to t on both sides gives

[tex]\dfrac{\mathrm dy}{\mathrm dt} = 2\cdot14t - \dfrac{(2+5t)(2t)-t^2(5)}{(2+5t)^2} - 0 \\\\ \dfrac{\mathrm dy}{\mathrm dt} = \boxed{28t - \dfrac{4t+5t^2}{(2+5t)^2}}[/tex]

You could go on to expand the rational expression into partial fractions. One way to do this:

[tex]\dfrac{5t^2 + 4t}{(2 + 5t)^2} = \dfrac{t(5t+2) + 2t}{(2+5t)^2} \\\\= \dfrac{t}{2+5t} + \dfrac{2t}{(2+5t)^2} \\\\= \dfrac15 \cdot \dfrac{t}{\frac25+t} + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 \cdot \dfrac{t+\frac25-\frac25}{\frac25+t} + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 \left(1 - \dfrac{2}{2+5t}\right) + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 - \dfrac{2}{10+25t}+ \dfrac{2t}{(2+5t)^2}[/tex]

and this would give

[tex]\dfrac{\mathrm dy}{\mathrm dt} = 28t - \dfrac15 + \dfrac2{10+25t} - \dfrac{2t}{(2+5t)^2}[/tex]

Answer: When air passes both above and below the airfoil, the air on top moves faster because of the curve, causing it to have a lower air pressure. This is according to Bernoulli’s principle, which states that faster moving air has less pressure than slower moving air. Also This is what causes the airplane to lift into the air.

At the equilibrium or balance point the meter stick stationary and the sum of the moments and forces acting on it is zero

Reason:

Known;

Length of the stick = 1 meter

Mass of the stick, m = 0.1 kg

Point the stick will balance when the dough is at one end = 0.33 m

Required:

How much mass does the dough have

Solution:

The meter stick is balanced when the clockwise moment and the anticlockwise moment about the balance point are equal

Let M, represent the mass of the dough, we have;

The center of mass of the meter stick = The 0.5 m point

Taking moment, we have;

Distance from the center of mas of the ruler to the fulcrum, d₁ = (0.5 - 0.33) m

Distance from the dough to the fulcrum, d₂ = 0.33 m

Clockwise moment, [tex]\mathbf{\sum M_{clockwise} }[/tex] = m × d₁

Anticlockwise moment, [tex]\mathbf{\sum M_{anticlockwise} }[/tex] = M × d₂

Therefore;

(0.5 - 0.33) × 0.1 = M × 0.33

Therefore, we get;
