Answer:

An independent variable is a variable that stands alone and isn't changed by the other variables you are trying to measure.

A dependent variable is something that depends on other factors.

Answer:

Relative: meredith's birth, the planting of jasmine's tree, and the extinction of the stegosaurus

WRITE ONE ADVANTAGE AND ONE DISADVANTAGE OF ALCOHOL AS A LIQUID USED IN THERMOMETERS

Advantage: Alcohol has a high expansivity.

Disadvantage: Alcohol is not opaque, this may give wrong temperature readings.

DIFFERENCE IN FORCES BETWEEN SOLID AND GAS PARTICLES :

Answer: Solids have stronger intetmolecular forces of attraction than gases.

TWO FACTORS TO INCREASE RATE OF EVAPORATION IN LIQUID :

Answer: Decreasing the volume of the container containing the liquid. This will increase vapour pressure as well the rate of evaporation .

Hi there!

For this part, we can disregard the horizontal velocity because horizontal and vertical motion are INDEPENDENT.

We can used the simplified equation to solve for time:

[tex]t = \sqrt{\frac{2h}{g}}[/tex]

Where:

h = height

g = acceleration due to gravity (assume g = 10 m/s²)

Plug in given values:

[tex]t = \sqrt{\frac{2(50)}{10}} = \sqrt{10}[/tex]

t ≈3.162 sec

Answer: false

Explanation:

When designing running shoes, the most useful bio metric is the average weight of a runner.

Usually, running shoes are designed with the particular concerns of the user in mind. A very useful biometric when designing running shoes is the average weight of the runner.

This is important because a heavier runner, for instance, will hit the ground with a greater force leading to greater impact. It is necessary that these runner have shoes that help to cushion this higher impact.

Hi there!

We can begin by calculating the total time of the ball's projectory:

t = d/v

t = 15/5 = 3 sec

We can use the simplified kinematic equation for time:

t = √2h/g

Rearrange to solve for h:

t² = 2h/g

gt² = 2h

gt²/2 = h

Plug in the values: (g = 9.8 m/s²)

9.8(3)² / 2 = 44.1 m

Answer:

1. Naturally occuring

2. Solid

3. Inorganic

4. Crystalline

5. Specific Chemical Compostion

Explanation:

Minerals are inorganic, crystalline solids that occur during biogeochemical processes in nature like in cooled lava or evaporated sea water. Minerals are not rocks, but are actually the components that make up rocks. Though they vary in color and shape, each mineral has a distinct chemical composition.

1. Minerals are formed by natural geological processes. Most minerals form from molten lava, sea evaporation or hot liquids in caves or cracks. Laboratory-generated minerals like synthetic gems made for commercial purposes are not considered actual minerals.

2. Though minerals vary in shape, color, luster (the way a mineral reflects light) and hardness, all minerals are a solid at a given temperature. If a substance is not in its solid state, it is not currently a mineral. For example, ice is a mineral, but liquid water is not. The Mohr scale, rates a minerals hardness from one to 10, 10 being the hardest. Diamond is the hardest mineral. Talc is a very soft mineral with a Mohr rating of one.

3. Minerals are wholly inanimate, inorganic compounds. But there are exceptions to this qualifier. There are rare organic substances with definitive chemical compositions that are labeled as “organic minerals." The most famous of this oxymoronic exception is whewellite. Whewellite is a component of kidney stones and coal deposits.

4. Most minerals will grow into a crystal shape, space permitting. Mineral deposits are often small because there is usually a variety of minerals in the same vicinity competing for the same room to grow. A mineral’s crystalline structure determines its hardness, cleavage (how it breaks) and color. There are six different crystal shapes: cubic, tetragonal, orthohombic, hexagonal, monoclinic and triclinic.

5. A mineral is defined by its chemical composition. A rock, on the other hand, does not have a specific chemical composition because it is a composite of a variety of minerals. Minerals are classified based on their anionic group. The major mineral groups are native elements, sulfides, sulfosalts, oxides and hydroxides, halides, carbonates, nitrates, borates, sulfates, phosphates and silicates. Silica is abundant in the Earth’s crust, so silicates are the most common group of mineral.

Answer:

The electrons from from NADH and FADH2 flow through the electron transport chain in the inner mitochondrial membrane generating a H+ buildup in the inner membrane space. This proton gradient (gradient of H+) flowing through the membrane enzyme complex ATP synthetase is the direct energy source for producing ATP.

How do you add two vectors?  

To add or subtract two vectors, add or subtract the corresponding components. Let →u=⟨u1,u2⟩ and →v=⟨v1,v2⟩ be two vectors. The sum of two or more vectors is called the resultant. The resultant of two vectors can be found using either the parallelogram method or the triangle method .

Hi there!

We can use the following equation to derive acceleration:

vf = vi + at, where:

vi = 0 m/s (starts from rest)

a = acceleration

time = time (sec)

Rewrite:

vf = at

Solve for acceleration:

vf/t = a

30/6 = 5 m/s²

       When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces. Hopefully this helps, have a nice day! :D
