a 15-kg block is on a frictionless ramp that is inclined at 20° above the horizontal. it is connected by a very light string over an ideal pulley at the top edge of the ramp to a hanging 19-kg block, as shown in the figure. the string pulls on the 15-kg block parallel to the surface of the ramp. find the magnitude of the acceleration of the 19-kg block after the system is gently released?
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].

Imagine that you design running shoes for a living. Which biometric would be most useful?
A.
the average weight of a runner
B.
the number of runners in a popular urban area
C.
the points of impact when the foot hits the ground
D.
the distance that beginning runners attempt to finish
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.

Compared to permanent magnets, why are electromagnets more useful in
many modern technologies?
O A. In permanent magnets, the strength of the magnetic field is more
consistent.
O B. To use an electromagnet, a power supply is not necessary.
O C. Strong permanent magnets are too large to use.
O D. By controlling the current, electromagnets can be turned on and
off.
We want to see why electromagnets are more useful in modern technologies.
We will see that the correct option is D:
"By controlling the current, electromagnets can be turned on and off."
An electromagnet is, as the name implies, a magnet that works with a power supply.
Why these are more useful than normal magnets?
Because you have more control over them. By controlling the current, you not only can turn it on and off, but you also could regulate the strength of the magnetic field.
This extra control is what makes the electromagnet a better option than a permanent magnet.
So the correct option is D: "By controlling the current, electromagnets can be turned on and off"

The voyager program was a space exploration program created to be the first to travel and explore the outer reaches of our solar system and beyond.
The voyager space probes were launched in 1977 and are still functional to this day, making them the longest running space exploration mission. The purpose of the voyager space probes is to relay information back to earth on the various planets and interplanetary objects they fly by.
Through these missions, NASA has received information regarding:
Jupiter's cloud formations and storm systems Volcanic activity on the Jupiter moon of IoInteresting discoveries about the rings of Saturn Voyager 2 discovered a huge magnetic field surrounding Uranus 10 additional moons seen to orbit Uranusand much more, making it already an extremely successful mission.
The voyager spacecrafts were designed and built by the United States of America with government funding and contributions from other renowned space agencies.
As of 2021, voyager 1 is moving with a velocity of 61 thousand km per hour , with voyager 2 moving at roughly 55 thousand km per hour putting them beyond the outer reaches of the inner solar system. This along with the many important finds they are responsible for make them worth the 890 million dollars they cost to build.

Identifying What are five things
that must be true in order for
a substance to be considered a
mineral?
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.
