When four solutes with the same mass and solubility are added to a solvent, they are likely to dissolve to the same extent, resulting in a homogeneous mixture. The explanation lies in the nature of solubility and the interactions between solutes and solvents.

When solutes are added to a solvent, their solubility determines the extent to which they dissolve. If all four solutes have the same solubility, it means they have similar chemical properties and can form favorable interactions with the solvent molecules. As a result, they will dissolve to the same extent, leading to a homogeneous solution where the solutes are evenly distributed throughout the solvent.

Solubility is influenced by factors such as temperature, pressure, and the nature of the solute and solvent. When solutes have the same mass and solubility, it suggests that their molecular structures and properties are similar. This similarity allows them to interact with the solvent in a comparable manner, resulting in equal dissolution. It is important to note that solubility can vary for different solutes if their properties or the conditions of the solvent change. However, in the given scenario, where solutes have the same mass and solubility, they are expected to dissolve equally in the solvent.

Answer:

The ball final velocity is 85.75 m/s

Explanation:

According to the problem, ball is dropped from the window and it experience an acceleration due to Earth's gravity which is denoted by g.

Initially, the ball is at rest, so its initial velocity is zero. The ball takes 8.75 s to fall from the window and hits the ground.

The equation of motion for constant acceleration is :

v = u + at

Here v is final velocity, u is initial velocity, t is time and a is acceleration.

In this case, u is zero and a is equal to g. So, the equation becomes :

v = gt

Substitute 8.75 s for t and 9.8 m/s² for g in the above equation.

v = 9.8 x 8.75

v = 85.75 m/s

The frictional force experienced on the coin, when it is at a distance of 14 cm is 0.77N and the coefficient of static friction when the coin slides off will be 0.964.

                         \(F_c=f_s=mrw^2=140*10^{-3}*24*10^{-2}*4\pi ^2\\f_s=1.325N\)

                   \(k=\frac{1.325}{140*10^{-3}*9.81}=0.964\)

Thus, we can conclude that, the frictional force experienced on the coin, when it is at a distance of 14 cm is 0.77N and the coefficient of static friction when the coin slides off will be 0.964.

A rocket ship has several engines and thrusters. While the solid rocket booster (srb) and main engines only work together during the first 2 minutes of flight, the main engines operate for a total of 8. 5 minutes after the launch. Once the srbs are released, the main engines alone accelerate the rocket from about 1341 m/s to 7600 m/s. During the first two minutes of flight, the SRB and main engine accelerate at a rate of 52.16 m/s2.

Acceleration is the rate at which a moving object's speed and direction change over time. When something moves faster or slower, it is considered to be accelerating. The engine's initial velocity (u), final velocity (v), and time of motion (t), which is equivalent to two minutes, are the parameters given (2 x 60 s).

The calculations for the main engine's and SRB's acceleration are listed below.

a= Δv / Δt

a=7600-1341 /2*60s

a=52.16 m/s²

As a result, during the first two minutes of flight, the main engine and SRB accelerate at a rate of 52.16 m/s2.

Answer:

Gravity is an ever present force, and therefore acceleration is guaranteed to happen at every single one of those points (and in fact, everywhere in the universe).

On top of that, friction will be present in all four spots (friction with the rails, with the air, with the axles, etc.), and friction is a perfectly acceptable force that will cause acceleration, slowing the roller coaster down.

So the correct answer is every single point, regardless of what answer the teacher expects.

The object will be moving faster if the acceleration and velocity are pointing in the same direction. The object will also slow down if the acceleration is pointing in the opposite direction as the velocity.

When an object's speed, direction of motion, or both change, it accelerates. Even while it may appear to be virtually immediate in some circumstances, such as when a golf ball is struck by a club or during car collisions, changes in an object's speed are always continuous.

Since gravity is a constant force, acceleration will unavoidably occur at each of those locations and throughout the whole universe.

Therefore, In addition, there will be friction at all four locations—friction with the axles, the air, the rails, etc.—and friction is a completely normal force that will accelerate the roller coaster, slowing it down.

Answer: organ system is the answer because of them working togather in two or more groups

Explanation:

Answer:

The correct option is;

B. Subtract vectors A from C; \(F_{Net}\) = 12 N

Explanation:

The given parameters are;

The weight of the dresser = 250 N

The force applied by the man = 20 N = C

The frictional force provided by the carpet = 8 N = The component of the weight resisting motion = A

Therefore, the net force tending to put the dresser in motion, \(F_{Net}\), is given as follows;

\(F_{Net}\) = The force applied by the man, C - The frictional force provided by the carpet which is the component of the weight resisting motion, A

\(F_{Net}\) = C - A = 20 N - 8 N = 12 N

\(F_{Net}\) = 12 N

The resulting net force, \(F_{Net}\) = 12 N.

The resultant force can be obtained by subtracting vector C from Vector A and the value of net force is 12 N. Hence, option (C) is correct.

Given data:

The weight of man is, W = 250 N.

The magnitude of applied force is, F = 20 N.

The magnitude of frictional force is, f = 8 N.

As per the given problem and the diagram let the applied force be denoted by vector A, Then,

Magnitude of Vector A = 20 N

And the frictional force be denoted by vector C. Then,

Magnitude of Vector C = 8 N

We know that the role of frictional force is to oppose the motion or to oppose the effect of applied force. Then the resultant force is given as,

\(F_{net} = F-f\\\\F_{net} = 20 - 8\\\\F_{net} = 12 \;\rm N\)

Thus, we can conclude that the resultant force can be obtained by subtracting vector C from Vector A and the value of net force is 12 N. Hence, option (C) is correct.

To determine the mass of granite, we must first understand the definition of density. Density is defined as the amount of matter present in a substance per unit volume.

We use the formula: density = mass/volume to calculate the mass of a substance given its density and volume. To calculate the mass of 54.3 m³ of granite, we use the following steps:

Given Density of granite = 2700 kg/m³Given volume of granite = 54.3 m³Let us substitute the values in the formula of density:density = mass/volume Solving for mass, we get:mass = density × volume Substitute the given values of density and volume into the formula:mass = 2700 kg/m³ × 54.3 m³

The m³ unit in the volume cancels out, leaving us with kg as the unit for mass.

We then solve the equation to get the mass:mass = 146,610 kg

Therefore, the mass of 54.3 m³ of granite is 146,610 kg.

Explanation:

Explanation:

the distance is easy. this is just the sum of the distances of the individual trips :

400 + 700 + 1200 = 2300 km

the displacement is trickier. this is the line of sight distance between the starting point of the first trip and the ending point of the last trip.

let's imagine a coordination grid with 1 km as unit size, and the starting point being the origin (0, 0).

so, then the trips subtract 400 units from y, then 700 units from x, and then further 1200 units from y.

so, the coordinates of the end point are (-700, -1600).

the displacement (straight distance from the origin) is then found by using Pythagoras

c² = a² + b² (c being the Hypotenuse, a and b the legs)

via the right-angled triangle of the coordinate differences to the origin :

displacement² = (-700)² + (-1600)² =

= 490000 + 2560000 =

= 3050000

displacement = sqrt(3050000) = 1,746.42492... km

According to the question the probability is approximately 0.4697, or 46.97%.

To find the probability that a power supply selected at random will conform to the voltage specifications, we can use the concept of standard deviation and the properties of a normal distribution.
Given:

Mean (μ) = 110 V

Standard deviation (σ) = 0.08 V

Lower specification (LS) = 109.95 V

Upper specification (US) = 110.05 V

We need to calculate the probability that the voltage is between LS and US.

To do this, we need to standardize the values using the Z-score formula:

Z = (X - μ) / σ

For the lower specification (LS):

Z_LS = (LS - μ) / σ

= (109.95 - 110) / 0.08

= -0.625

For the upper specification (US):

Z_US = (US - μ) / σ

= (110.05 - 110) / 0.08

= 0.625

Now, we can use a standard normal distribution table or calculator to find the probabilities associated with these Z-scores.

The probability that the power supply will conform to the voltage specifications is given by the area under the normal curve between Z_LS and Z_US.

P(LS < X < US) = P(Z_LS < Z < Z_US)

From the standard normal distribution table, the probability associated with Z = -0.625 is approximately 0.2659855, and the probability associated with Z = 0.625 is approximately 0.7356648.

Therefore, the probability that a power supply selected at random will conform to the specifications on voltage is:

P(LS < X < US) = P(-0.625 < Z < 0.625)

= 0.7356648 - 0.2659855

= 0.4696793

So, the probability is approximately 0.4697, or 46.97%.
