Explanation:
A weight of 2. 0 N i hung from a pring. The extenion produced i 6. 0 cm. The 2. 0 N weight i
removed and an 8. 0 N weight i hung from the pring. The pring doe not pa it limit of
proportionality. What i the new extenion of the pring?
A 6. 0 cm B 24 cm C 36 cm D 48 cm
When a 2.0 N weight is removed by us and an 8.0 N weight is hung from the spring, the new extension of the spring is 24 cm.
The extension of the spring is known to be directly proportional to the weight which hangs from it. The extension of an object is directly proportional to the force on it.
We can say, in other words, that If the force applied is doubled, the extension doubles. If no force is applied, there is no extension. The graph of force versus extension is a straight line through the origin, which shows a linear relationship.
W∝ x
W= K x
This means,
W1=Kx1 and W2= Kx2
So, we have a relationship,
W1/x1=W2/x2
2/6= 8/x2
so we have,
x2=24 cm.
The length of the spring will be 24 cm in this case.

The Mercalli intensity scale is a scale to measure the intensity of earthquakes. Unlike the Richter scale, the Mercalli scale does not take into account the energy of an earthquake directly. Rather, they classify earthquakes by the effects they have.
A girl and boy are moving a wagon full of books across the floor at a constant speed. We know the girl is pulling the wagon at an angle of 36.9 degrees. She is pulling with a force of 50N and the boy is pushing with a force of 30N. The mass of the wagon and books together is 90kg.
0.88m/s is the the acceleration when the girl is pulling the wagon at an angle of 36.9 degrees. She is pulling with a force of 50N and the boy is pushing with a force of 30N. The mass of the wagon and books together is 90kg.
What is Force?A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
The given data :
Pushing force by boy =30N
pulling force by Girl=50N
Mass of wagon and books together= 90kg
angle of pulling =36.9 degree
so the acceleration will be=F/m
hence net force =30+50N=80N
a=80/90
a=0.88m/s
Hence, 0.88m/s is the the acceleration when the girl is pulling the wagon at an angle of 36.9 degrees. She is pulling with a force of 50N and the boy is pushing with a force of 30N. The mass of the wagon and books together is 90kg.

what is the maximum mass of block a for which the system remains in static equilibrium? express your answer with the appropriate units.
Mass is one of the fundamental properties of an object in Physics, and is a measurement of how much matter there is in something.
How to finding Mass from Density and Volume?Look up the object's density. Density measures how tightly the matter in an object is packed together. Each material has its own density, which you can look up online or in a textbook. The scientific unit of density is kilograms per cubic meter (kg/m3), but you can use grams per cubic centimeter (g/cm3) for smaller objects.Matter is any substance that you can touch — anything that takes up physical space and has volume. Use this formula to convert between these units: 1,000 kg/m3 = 1 g/cm3The density of liquids is often measured in kilograms per liter (kg/L) or grams per milliliter (g/mL) instead. These units are equivalent: 1 kg/L = 1 g/mL.Example: Diamond has a density of 3.52 g/cm3. 2. Measure the object's volume. The volume is the amount of space the object occupies. Measure the volume of solids in cubic meters (m3) or cubic centimeters (cm3), and the volume of liquids in liters (L) or milliliters (mL). The formula for volume depends on the shape of the object. Refer to this article for common shapes.Use the same unit that appears as part of your density measurement.Example: Since we measured the density of diamond in g/cm3, we should measure our diamond's volume in cm3. Let's say our diamond's volume is 5,000 cm3. 3. Multiply the volume and density together. Multiply your two numbers together, and you'll know the mass of your object.[1] Keep track of the units as you do this, and you'll see that you end up with units of mass (kilograms or grams).Example: We have a diamond with volume 5,000 cm3 and density 3.52 g/cm3. To find the diamond's mass, multiply 5,000 cm3 x 3.52 g/cm3 = 17,600 grams.To learn more about Equilibrium refer to:

which of the following is true? a) You can have acceleration not equal zero, butvelocity equal to zero.b) You can have acceleration equal to zero, butvelocity not equal to zero.c) You can accelerate without changing your speed.d) all of the abovee) A and B
The correct answer is option A.
We can have velocity equal to zero but acceleration not equal to zero.
We know that acceleration depends on the velocity which depends on the direction and time.
But there are times when a body can be said to be accelerating even when the velocity is zero.
Velocity is a vector quantity and is defined as the rate of change of displacement of an object with time. On the other hand, acceleration is the time rate of change of velocity.
The acceleration is
a = dv/dt
For zero acceleration
0 = dv / dt
It is possible that the acceleration of a particle is non-zero and velocity is zero at the same instant.
At the point where the velocity becomes zero, only the instantaneous velocity of the body is zero, at any time before or after this time, the object has a non-zero velocity.
For example, if a ball is thrown up then at the highest point, velocity is zero but the acceleration is non-zero.
This means that there is still change in the velocity when the velocity of the object reaches zero. Therefore, the body is still accelerating.
By the property of Simple Harmonic Motion, we can tell that when a ball is thrown upwards on earth with a constant velocity, the gravitational force of the earth acts on it in the opposite direction.
Therefore, at the highest point, the velocity of the ball becomes zero, after which it starts to fall down. At this point, the velocity of the ball is zero yet its acceleration is equal to g = 9.8 m/s² which is a non-zero and the body is said to be accelerating even if the velocity is equal to zero.

By changing their AIMD formulas in this way, we can make both flows converge to 3r/4 and r/4 respectively.
What is AIMD?
The AIMD (Additive Increase, Multiplicative Decrease) congestion control algorithm is a type of feedback control in which the sender increases the window size by a certain amount (additively) after each round trip time (RTT) and then reduces the window size (multiplicatively) when it detects packet loss. This algorithm is used to ensure fair sharing of the network resources.
In the given scenario, if we want to make both flows converge to 3r/4 and r/4, we can modify their AIMD formulas. We can do this by changing the rate at which the window sizes increase (i.e. the additive increase) and decrease (i.e. the multiplicative decrease).
For the flow that should end up with 3r/4, we can reduce the rate of additive increase and increase the rate of multiplicative decrease. This will make the flow increase its window size more slowly and decrease its window size more quickly, resulting in it converging to a smaller window size of 3r/4.
For the flow that should end up with r/4, we can do the opposite, i.e. increase the rate of additive increase and reduce the rate of multiplicative decrease. This will make the flow increase its window size more quickly and decrease its window size more slowly, resulting in it converging to a smaller window size of r/4.

E(x) = 200e⁻²ˣ
E(1.6) = 200e⁻²⁽¹°⁶⁾
E(1.6) = 200e⁻³°²
E(1.6) = 200/e³°²
E(1.6) = 200/24.533
E(1.6) = 8.15 V/m
So, E(1.6) = 8.15 V/m

atomic orbitals developed using quantum mechanics
The position and wave-like activity of an electron in an atom in terms of both atomic theory and quantum mechanics. This function can be used to determine the likelihood of discovering any atom's electron.
What does the quantum mechanical model mean by an atomic orbital?The area of an atom that an electron is most likely to be in 90% of the time is known as an atomic orbital. According to the Heisenberg uncertainty principle, it is impossible to know an electron's energy and position at the same time.
How are quantum numbers connected to atomic orbitals?Three quantum numbers describe the characteristics of an atomic orbital. Any positive integer can be the main quantum number, n. The average distance between an electron's nucleus and its orbital energy is related to n in general.

Correctly label the following anatomical parts of a kidney. The designations of "cortex" and "medulla' are misleading, perhaps because of differences in mammalian kidney structure among different species. Cortex refers to the outer perimeter and medulla comprises the pyramids and columns However, there is no fundamental difference between the composition of the cortex and that of the columns, both contain corpuscles that project tubules into the pyramidal regions.

What is kidney?One of two organs in the abdomen. Kidneys remove waste and excess water (such as urine) from the blood and balance chemicals (such as sodium, potassium, and calcium) in the body. Kidneys also produce hormones that help control blood pressure and stimulate the bone marrow to make red blood cells.
