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.
A bicyclist brakes from 21.7 m/s to a stop in 32.3 m.
What is the acceleration of the bicyclist?
How much time does it take for the bicyclist to stop?
What is the bicyclist’s average speed?
The acceleration of the bicycle during the motion before stopping is 7.29 m/s².
The time taken for the bicycle to stop is 2.98 s.
The average speed of the bicycle is 10.83 m/s.
The given parameters;
initial velocity of the bicycle, u = 21.7 m/sdistance traveled by the bicycle, s = 32.3 mThe acceleration of the bicycle is calculated ad follows;
v² = u² + 2as
where;
v is the final velocity of the bicycle after stopping = 0
0 = u² + 2as
-2as = u²
[tex]a = -\frac{u^2}{2s} \\\\a = \frac{(21.7)^2}{2\times 32.3} \\\\a = -7.29 \ m/^2\\\\|a| = 7.29 \ m/s^2[/tex]
The time taken for the bicycle to stop is calculated as;
v = u + at
0 = 21.7 - 7.29t
7.29t = 21.7
[tex]t = \frac{21.7}{7.29} \\\\t = 2.98 \ s[/tex]
The average speed of the bicycle is calculated as;

traveled 60 m?
h
Answer in units of m/s.
how Long does it take the car to travel 60m?
answer in units of s

If Ms. Ramirez drops a watermelon from the top of the second-floor fire escape outside her room, and it takes 1.5 seconds to hit the ground, calculate the velocity of the watermelon as it hits the ground.
The velocity of the watermelon as it hits the ground is 14.715 m/s.
Given the data in the question;
Since the Watermelon was dropped from rest,
Initial velocity of the Watermelon;[tex]u = 0m/s[/tex]Time taken for the Watermelon to hit the ground; [tex]t = 1.5s[/tex]We know that, Acceleration due to gravity; [tex]g = 9.81 m/s^2[/tex]Now, we determine the velocity of the watermelon as it hits the ground which is the final velocity.
From the First Equation of Motion:
[tex]v = u + at[/tex]
Now, under gravity, acceleration ''a" will Acceleration due to gravity;[tex]g = 9.81m/s^2[/tex], "v" is the final velocity, "u" is the initial velocity and "t" is the time taken.
So, we substitute our values into the equation
[tex]v = 0m/s\ +\ ( 9.81m/s^2\ * 1.5s )\\\\v = ( 9.81m/s^2\ * 1.5s )\\\\v = 14.715 m/s[/tex]
Therefore, the velocity of the watermelon as it hits the ground is 14.715 m/s

im confused on number two can u help me through it
Hi there!
We can solve this in two ways, using the Work-Energy theorem or kinematics.
Work-Energy:
We know that:
Ei = Ef, as long as there are no external forces working on the system.
Thus:
Ei = PE = mgh
Ef = KE = 1/2mv²
Therefore:
mgh = 1/2mv²
We can cancel out the mass:
gh = 1/2v²
9.8(10) = 1/2v²
√196 = v = 14 m/s
We can also solve using kinematics, using the equation:
vf² = vi² + 2ad
From rest (vi = 0 m/s) and a = g, so:
vf² = 2gd
vf = √2gh
vf = √(2 × 9.8 × 10) = 14 m/s

How do X rays use electromagnetic waves to function?
X-rays are very high-frequency waves and carry a lot of energy. They will pass through most substances, making them useful in medicine and industry to see inside things. An X-ray machine works by firing a beam of electrons at a "target." If we fire the electrons with enough energy, X-rays will be produced.

A 0.12 kg object makes an elastic head-on collision with a 0.18 kg stationary object. The final velocity of the 0.12 kg object after the collision is 0.048 m/s in the direction opposite its initial movement. The final velocity of the 0.18 kg object after the collision is 0.19 m/s in the same direction as the object which strikes it. What was the initial velocity of the 0.12 kg object?
Answer:
0.12kg / 0.19
Explanation:
Becase the volcity reuded
The final velocity of the 0.18 kg object after the collision is 0.19 m/s in the same direction as the object which strikes it, then the initial velocity of the 0.12 kg object would be 0.237 m / s .
What is momentum?It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.
As given in the problem, a 0.12 kg object makes an elastic head-on collision with a 0.18 kg stationary object. The final velocity of the 0.12 kg object after the collision is 0.048 m/s in the direction opposite its initial movement. The final velocity of the 0.18 kg object after the collision is 0.19 m/s in the same direction as the object which strikes it.
By using the conservation of the momentum,
v × 0.12 + 0 × 0.18 = ( - 0.048)× 0.12 + 0.19 × 0.18
v = 0.237 m / s
Thus, the initial velocity of the 0.12 kg object would be 0.237 m / s .
