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!

Since the string is light and there is no friction in the pulley, the acceleration of the system is equal to the acceleration of both blocks.

We can begin by summing the forces of each block:

Block on incline:

- Force of gravity (in the negative direction away from the acceleration)

- Force of Tension

∑F = -M₁gsinФ + T

Block hanging:

- Force of gravity (Positive, in direction of acceleration)

- Force of Tension (Negative, opposite from acceleration)

∑F = M₂g - T

Sum both of these net forces for each block:

∑Fт = -M₁gsinФ + T - T + M₂g

∑Fт = -M₁gsinФ + M₂g

Divide by the mass to solve for acceleration:

[tex]a = \frac{-M_1gsin\theta+M_2g}{M_1+M_2}[/tex]

Plug in the given values:

[tex]a = \frac{-(15)(9.81)(sin20)+19(9.81)}{15+19} = 4.002 m/s^2[/tex]

The magnitude of the acceleration of the 19-kg block is 4.0 m/[tex]s^{2}[/tex].

The 15-kg block is accelerating down the ramp, and the 19-kg block is accelerating up. The string connecting the two blocks is taut, so it must be applying a force to both blocks. The force of the string on the 15-kg block is equal to the force of the string on the 19-kg block.

Let's call the force of the string on the 15-kg block T. We can use Newton's second law to write two equations for the acceleration of the two blocks:

For the 15-kg block: T - mg sin(θ) = 15a

For the 19-kg block: T = 19a

where:

m is the mass of the block

g is the acceleration due to gravity

θ is the angle of the ramp

a is the acceleration of the block

Plugging the second equation into the first equation, we get:

19a - mg sin(θ) = 15a

Solving for a, we get:

a = (mg sin(θ)) / (4m)

= (15 kg * 9.8  m/[tex]s^{2}[/tex] * sin(20°)) / (4 * 15 kg)

= 4.0 m/[tex]s^{2}[/tex]

Therefore, the magnitude of the acceleration of the 19-kg block is 4.0  m/[tex]s^{2}[/tex].

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

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.

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.
