In this model, the reaction favours the reactants and the equilibrium is to the left.
Equilibrium and an example are what?It is argued that an equilibrium is stable when tiny, environmentally induced displacements from it result in forces that have a tendency to oppose the displacement and bring the body or particle back to the equilibrium state. A brick placed flat on the ground or a weight held by a spring are two examples.
Equilibrium responses - what is it?When a reaction is said to have "reached equilibrium," it suggests the rate of forward reaction and the rate of reversal are now equal. Due to the rate of forward reactions being equal to the reaction's opposite rate, the quantity or concentrations of both reactants and outcomes remain unchanged.

Among the given options d. Shatong is not a target game.
In the Filipino game of "Batuhang Bola," participants aim tiny stones or balls towards a target to get points. In the Filipino game of "Tumbang Preso," participants attempt to topple a tin can by hurling slippers or other things at it. Chinese Garter is a jumping game where participants attempt to conquer higher levels with each successful jump over a stretched garter or elastic band held by two persons.
Shatong is not a game of aim or a target. Using sticks or straws, participants attempt to flick or strike tiny shells or pebbles in order to get them to drop on a target or inside a defined area. In contrast to the other games listed above, it does not entail hitting or aiming at a particular target. Thus, it is not a target game.

BRAINLIEST TO GOOD ANSWER: In this case, what would the net force be if the static friction force is greater than the applied force?
There's no movement of the block but mathematically, technically the net force is in the direction of the friction force. Would I just write net force as 0 and cancel the static friction beyond the magnitude of the applied force?
The frictional force if greater than the applied force, then the movement of the block gets resisted against the applied force and the block does not undergo any displacement.
What is force?Force is an external agent actin on an object to change its motion or to deform it. There are various kinds of forces such as frictional force, gravitational force, magnetic force etc.
If two or more same or different forces acting on an object from the same side they will add up in magnitude. If two forces with same magnitude are acting from opposite direction of the object, then they will cancel each other and the net force will become zero. This situation is called the balanced force.
If two unequal force acts from opposite direction, the net force is the substracted value of their magnitudes and the situation is called unbalanced force.
Here, the frictional force if greater than the applied force, then the movement of the block gets resisted against the applied force and the block does not undergo any displacement.

Find the magnitude of the resultant vector A⃗ + B⃗ .
Use the dot product identity,
\(\vec x \cdot \vec y = \|\vec x\| \|\vec y\| \cos(\theta)\)
where \(\theta\) is the measure of the angle between the two vectors \(\vec x,\vec y\). Note that
\(\vec x \cdot \vec x = \|\vec\| \|\vec x\| \cos(0) = \|\vec x\|^2\)
Applying the identity to \(\vec x = \vec y = \vec A + \vec B\) and using the distributive and commutative properties of the dot product, we get
\((\vec A + \vec B) \cdot (\vec A + \vec B) = (\vec A \cdot \vec A) + 2 (\vec A \cdot \vec B) + (\vec B \cdot \vec B)\)
which is equivalent to
\(\|\vec A + \vec B\|^2 = \|\vec A\|^2 + 2\|\vec A\|\|\vec B\| \cos(\theta) + \|\vec B\|^2\)
Now, we're given \(\|\vec A\| = 13.9\), \(\|\vec B\| = 5.9\), and \(\theta=53^\circ\), so that
\(\|\vec A + \vec B\| = \sqrt{13.9^2 + 2\cdot13.9\cdot5.9\cos(53^\circ) + 5.9^2} \approx \boxed{18.1}\)

Which evdence that a chemical reaction has likely occurred?
A. A liquid slowly losing volume
B. The formation of a precipitate
C. Boiling water releasing
D. A change in the shape of a solid
B) The evidence that a chemical reaction has likely occurred is the formation of a precipitate.
A precipitate is a solid that forms from a chemical response in a liquid result. This is a clear suggestion that a chemical response has taken place because the reactants have experienced a chemical change to form a new product that's undoable in the original detergent. Option A( a liquid sluggishly losing volume) may be an suggestion of evaporation or immersion, but it doesn't inescapably indicate a chemical response.
Option C( boiling water releasing) is a physical change caused by a change in temperature, not a chemical response. Option D( a change in the shape of a solid) could be a sign of a physical change, similar as melting or breaking, but it isn't a clear suggestion of a chemical response. thus, the conformation of a precipitate( option B) is the most dependable substantiation that a chemical response has likely passed.

a car is traveling at 20 meters/seconds anf is brought to rest by applying breaks over a period of 4 seconds. what is its average acceleration over this time in time interval
Answer:
2.5m/s²
Explanation:
Given the following:
Initial velocity u = 0m/s
Final velocity v = 20m/s
Time t = 4s
Required
average acceleration over this time in time interval
Using the equation of motion
v = u + at

The average monthly sea surface temperature at 5°N and 140°W, according to the map, is approximately 26°C.
Lines of latitude indicate degrees north and south of the equator, and areas of equal temperature are represented by these lines. In this case, we are interested in the sea surface temperature at the coordinates 5°N and 140°W. To determine the approximate temperature at this location, we refer to the map. The map likely uses color representations to indicate temperature, with different colors representing different temperature ranges.
By examining the map, we can identify the region around 5°N and 140°W and determine the corresponding color or temperature range associated with it. Based on the given options, we look for the color or temperature range that aligns with an approximate value of 26°C. This temperature corresponds to the average monthly sea surface temperature at 5°N and 140°W according to the map.
It's important to note that the accuracy of the answer depends on the specific map being referred to and any additional information provided. Maps can vary in their level of detail and the specific color scales used to represent temperature, so it's essential to consider these factors when interpreting the map and determining the corresponding temperature value.

Answer:

d = 100 meters plus the depth of the well
d = 100 + x where x is the depth of the well.
vi = 0 m/s The object is dropped. It was not thrown.
t = 5 seconds
a = 9.81 m/s^2
formula
d = vi*t + 1/2 a t^2
solution
100 + x = 0 + 1/2 * 9.81 * 5^2
100 + x = 122.625 Subtract 100 from both sides
x = 122.625 - 100

Leon is testing an unknown
substance and observes that the
substance retains its volume and
shape when placed in different
containers. Which phase of matter
is the substance most likely in?
The observation that a substance retains its volume and shape when placed in different containers indicates that the substance has a fixed volume and shape, which is a characteristic of a solid.
Solids have a fixed shape and volume because the particles that make up a solid are packed tightly together and held in a fixed position by intermolecular forces. As a result, solids maintain their shape and volume even when placed in different containers or when subject to external forces.
In contrast, liquids do not have a fixed shape, but rather take on the shape of their container. They do, however, have a fixed volume. This means that a liquid would change its shape to match the shape of its container, but its volume would remain constant.
Gases, on the other hand, do not have a fixed shape or volume. They take on the shape and volume of their container and are highly compressible.
Based on the observation that the substance retains its volume and shape when placed in different containers, it is most likely in a solid state. However, further testing may be needed to confirm this, as some liquids and even some gases can also exhibit a degree of fixed volume and shape under certain conditions.
