“The electric flux through a closed surface is equal to the net charge inside the surface divided by the physical constant. This law is a fundamental principle in electrostatics and is expressed mathematically as E.ds = Q/ε0.

Gauss’s Law for electric fields is a fundamental principle in physics, specifically in the study of electrostatics. The law describes the relationship between the electric flux and the distribution of electric charges in a given space. Simply put, it states that the electric flux through a closed surface is proportional to the total amount of electric charges inside the surface. In mathematical terms, the statement of Gauss’s Law for electric fields is as follows: E.ds = Q/ε0Here, E.ds represents the electric flux through a closed surface, Q represents the total electric charge enclosed within the surface, and ε0 is the physical constant known as the permittivity of free space. This equation can be used to calculate the electric field created by a given charge distribution, provided that the electric flux through a closed surface around the distribution is known.

Gauss’s Law for electric fields states that the electric flux through a closed surface is proportional to the net electric charge enclosed within the surface. This law is a fundamental principle in electrostatics and is expressed mathematically as E.ds = Q/ε0.

Types Of Energy Transfers

Heat can be transferred in three ways: by conduction, convection, and by radiation.

During the day, the radio primarily receives AM (Amplitude Modulation) stations from a nearby city due to the influence of various factors, including the behavior of radio waves and the Earth's atmosphere :

During the day, the ground wave propagation is more effective than the skywave propagation. The ground wave of AM stations from nearby cities is able to propagate relatively well and reach your location. However, the ground wave's range is limited due to absorption, reflection, and refraction caused by the temperature gradient in the lower atmosphere. At night, the absence of solar radiation on the ionosphere causes it to become more reflective. This leads to an increase in skywave propagation, enabling AM signals from more distant cities to bounce off the ionosphere and reach your location. The increased range allows you to pick up stations from the distant city that were previously beyond the reach of the ground wave during the day.

To find the magnitude of x in the given system of equations, (1- j9)x + (2 + j10)y = 4 + j3 and (2 - j2)x + (7 - j6)y = -5 + j17,

Step 1: Represent the given equations in matrix form.
A = [ [1 - 9j, 2 + 10j], [2 - 2j, 7 - 6j] ]
B = [ [4 + 3j], [-5 + 17j] ]

Step 2: Solve for the inverse of matrix A, denoted as A_ inv.
A_ inv = 1/det(A) * ad jugate(A), where det(A) is the determinant of matrix A and ad jugate(A) is the ad jugate of matrix A.

Step 3: Compute the determinant of matrix A.
det(A) = (1 - 9j)(7 - 6j) - (2 + 10j)(2 - 2j) = 23 - 56j

Step 4: Compute the ad jugate of matrix A.
ad jugate(A) = [ [7 - 6j, -2 - 10j], [-2 + 2j, 1 - 9j] ]

Step 5: Compute the inverse of matrix A.
A_ inv = 1/(23 - 56j) * [ [7 - 6j, -2 - 10j], [-2 + 2j, 1 - 9j] ]

Step 6: Solve for the matrix X by multiplying A_ inv with B.
X = A_ inv * B = [ [x], [y] ]

The magnitude of the horizontal force F necessary to drag block B to the left at a constant speed can be determined by the frictional force acting on block B.

The frictional force acting on block B opposes its motion and determines the magnitude of the necessary horizontal force F. To calculate the frictional force, we use the equation: frictional force = coefficient of kinetic friction * normal force.

In this scenario, the coefficient of kinetic friction between all surfaces is given as 0.20. The normal force on block B is equal to its weight, which is 4.00 N. By multiplying the coefficient of kinetic friction by the normal force, we can determine the magnitude of the frictional force.

The magnitude of this force will be equal to the magnitude of the necessary horizontal force F required to counteract it and keep block B moving at a constant speed to the left.

Answer:

a state in which opposing forces or influences are balanced.

Explanation:

The time taken for the car to cover the distance of 125 m is 5 seconds

From the question given above, the following data were obtained:

The time taken for the car to cover the 125 m distance can be obtained as illustrated below:

s = (u + v)t / 2

125 = [(10 + 40) × t] / 2

125 = (50 × t) / 2

Cross multiply

50 × t = 125 × 2

50 × t = 250

Divide both sides by 50

t = 250 / 50

t = 5 s

Thus, the time taken by the car to cover the 125 m distance is 5 seconds

Bridge failure is described as the inability of a constructed bridge or its components to perform as specified in the design and construction criteria, which is typically associated with substantial financial and lives losses.

Based on 10 prior investigations, this report provides a summary of recent studies on the usual traits and causes of bridge failures. The two categories of primary causes are internal and external, or natural and human forces. Over 70% of bridge failures are caused by the top 5 major causes of bridge failures: design error, construction problems, hydraulic, accident, and overload. Bridge collapse causes are highly correlated with the local economy, the structure's use, its material type, and its age in operation.

The number of distinct values of resistance that can be made is five. So, option D. is correct.

1. Let's represent the resistance of each identical resistor as R.
2. Consider the possible combinations:
  a. No resistor connected:

This case doesn't contribute to a resistance value.
  b. One resistor connected:

The resistance value is R.
  c. Two resistors connected in series:

The resistance value is R + R = 2R.
  d. Two resistors connected in parallel:

The resistance value is (R * R) / (R + R) = R/2.
  e. Three resistors connected in series:

The resistance value is R + R + R = 3R.
  f. Three resistors connected in parallel:

The resistance value is (R * R * R) / (R * R + R * R + R * R) = R/3.
  g. One resistor in parallel with two resistors in series:

The resistance value is (R * (R + R)) / (R + (R + R)) = (2 * R) / 3.

Answer:

I'm not that busy solving but I'll tell you the formula that Force x distance is equal to work done

The work is done on a pumpkin when we lift it by 15 m with 24 N is 360 J

Work done is the amount energy gained (loosed) in bringing the body from initial position to final position. It is denoted by W and its SI unit is joule(J).  

i.e. Work(W) is force(F) times displacement(s).

W=F× s

When a body is displaced with 1 newton of force by 1 m, then we can say that work has been done on the body by 1 joule.

Writing for it's dimension,

W=F× s

Force has dimension [L¹ M¹ T²]

Displacement has dimension [L¹]

multiplying both the dimensions Force and Displacement  

we get,

dimension of Work [L² M¹ T²]

According to newton's second law of motion,

Force(F) is mass(M) times acceleration(a).

i.e. F=ma

Given,

Force = 24 N

Displacement = 15 m

W=F.s= 24*15 = 360 J

Hence work done on pumpkin is 360 J

Answer:

\(f=7.5\times 10^{14}\ Hz\)

Explanation:

Given that,

The wavelength of light, \(\lambda=400\ nm=400\times 10^{-9}\ m\)

The speed of light, \(c=3\times 10^8\ m/s\)

We need to find the frequency of light. We know that,

\(c=f\lambda\)

Where

f is the frequency

So,

\(f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{400\times 10^{-9}}\\\\f=7.5\times 10^{14}\ Hz\)

So, the frequency of light is \(7.5\times 10^{14}\ Hz\).

Answer:

A cannon ball of mass 4.0 kg is fired from a stationary 96 kg cannon at 120 m/s. Calculate the velocity of the cannon immediately after firing.

total momentum of cannon and cannon ball before = 0 kg m/s - because neither object is moving

total momentum of cannon and cannon ball after collision = 0 kg m/s - because momentum is conserved

Momentum of cannon ball after firing = 4.0 × 120 = 480 kg m/s.

Momentum of cannon after firing = -480 kg m/s (because it recoils in the opposite direction and 480 - 480 = 0 kg m/s, the total momentum after collision).

Rearrange p = m v to find v:

v = p/m

v = 480 divided by 96

v = 5.0 m/s

Note that the forward velocity of the cannon ball was given a positive value. The negative value for the cannon's velocity shows that it moved in the opposite direction.

Not charged - balloon A
