Gauss's law states that the total electric flux through any closed surface is proportional to total electric charge inside the surface.
The electric flux is the measure of the electric field through a given surface. The electric field is the gradient of the potential. The density of the lines corresponds to the electric field strength, which could also be called the electric flux density. Electric flux is proportional to the total number of electric field lines going through the surface.
Electric flux has SI units of volt meters or equivalently newton meters squared per coulomb. Thus, the SI base units of electric flux are kg m3s -3*A-1.
The quantity EA1 is the electric flux through S1. We represent the electric flux through an open surface like S1. Electric flux is a scalar quantity.

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.

consider the fairness properties of aimd. now, consider a scenario where two flows are competing at a bottleneck with capacity r, where each of them has the same rtt. using standard aimd, both flows will converge to a regime where each gets r/2. discuss how by changing their aimd formulas you can make them converge to 3r/4 and r/4.
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.
By changing their AIMD formulas in this way, we can make both flows converge to 3r/4 and r/4 respectively.

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:

A. The electric field E(x) at x = 1.0 m is 27.07 V/m
B. The electric field E(x) at x = 1.6 m is 8.15 V/m
What is electric potential?Electric potential is work done in moving a unit charge from one point to the other.
What is electric field?Electric field is the ofrce per unit charge acting at a point in an electric field.
A) What Is E(x) at x = 1.0 m?Given that the electric potential V = 100e⁻²ˣ V, the electric field is given by
E = -dV/dx = -d100e⁻²ˣ/dx
= -100de⁻²ˣ/dx
= -100 × -2 × e⁻²ˣ
= 200e⁻²ˣ
Since we require the electric field at x = 1.0nm, substituting the value of x = 1.0 into the equation, we have
E(x) = 200e⁻²ˣ
E(1.0) = 200e⁻²⁽¹⁾
E(1.0) = 200e⁻²
E(1.0) = 200/e²
E(1.0) = 200/7.3891
E(1.0) = 27.07 V/m
So, E(1.0) = 27.07 V/m
B) What Is E(x) at x = 1.6 m?Given that V = 100e⁻²ˣ V, the electric field is given by
E = -dV/dx = -d100e⁻²ˣ/dx
= -100de⁻²ˣ/dx
= -100 × -2 × e⁻²ˣ
= 200e⁻²ˣ
Since we require the electric field at x = 1.6 m, substituting the value of x = 1.6 into the equation, we have
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

[tex]N_{s}[/tex] = turns per unit length of the solenoid
I = current flowing through the solenoid
Now, it is given to us that the magnitude of magnetic field at a radial distance of s inside the toroid is equal to the magnitude of magnetic field inside the solenoid.
=> [tex]B_{t} =[/tex] [tex]B_{s}[/tex]
=> (μ₀[tex]N_{t}[/tex]I)/(2[tex]\pi[/tex]s) = μ₀[tex]N_{s}[/tex]I
Since it is given that the current is same through both toroid and solenoid, the above equation can be written as -
=> [tex]\frac{N_{t}}{2\pi s} =N_{s}[/tex]
[tex]= > \frac{300}{2\pi s} =400\\= > 800\pi s=300\\= > s = \frac{300}{800\pi } \\= > s = 0.11 m\\= > s = 12 cm[/tex]
Thus the radial distance from the center of the toroid is 12 cm such that the magnitude of magnetic field through the toroid is equal to that found inside the solenoid.

brightness is to light as ________ is to sound.
Brightness is to light as loudness is to sound.
What is Brightness?Brightness is the visual attribute by which a light source appears to emit or reflect light. In other words, brightness is the perception caused by the brightness of a visual object. Not necessarily proportional to luminance.
What is loudness?Loudness is often confused with volume. However, the two terms are completely different concepts. Loudness is a scientific measure of the amount or strength of sound. Loudness, on the other hand, is much more difficult to quantify as it is entirely subjective and based solely on your personal perception of sound. The frequency content, duration, and loudness of a sound are factors in how loudness is perceived.

for a 3-sided joint, it is a good practice to place a nonadhering plastic bond breaker strip to the concealed side (inner side) before applying joint sealant.
For a 3-sided joint, it is a good practice to place a nonadhering plastic bond breaker strip to the concealed side (inner side) before applying joint sealant is a true statement.
What is the sealant about?The level of attention taken before applying the sealant will determine how effectively it adheres to the surface. The first step in joint preparation is a site inspection by the sealant contractor to ensure that all joint dimensions are in accordance with the requirements.
All parties shall be informed if the width or depth of joints deviates from those stated owing to component location, incorrect component size, workmanship defects, weathering, or other joint modifying factors.
