The plane travels a distance of 325 miles if the airplane travels for 2.5 hours at an average speed of 130 miles per hour. Using the distance formula (d = rt), we can calculate the distance.

To find the distance traveled by the airplane, we can use the distance formula, which is represented as d = rt. In this formula, "d" represents the distance, "r" represents the rate or speed at which the object is traveling, and "t" represents the time taken for the travel.

Given that the airplane travels for 2.5 hours at an average rate of 130 miles per hour, we can substitute these values into the formula. The rate of the airplane is 130 miles per hour, and the time taken is 2.5 hours.

Using the formula, we can calculate the distance traveled as follows:

d = rt

d = 130 mph × 2.5 hours

Multiplying the rate (130 mph) by the time (2.5 hours) gives us:

d = 325 miles

Therefore, the airplane travels a distance of 325 miles during the 2.5 hours of travel at an average rate of 130 miles per hour.

\(R = (Q/(2\pi \psi _0E_m))^{1/2\) is the expression for the radial distance at which the field is at its magnitude maximum Em.

The electric field magnitude Em due to a spherically symmetric distribution of charge is given by:

\(E_m = (1/4\pi \psi 0) * (Q/R^2)\)

where Q is the total charge of the sphere, R is its radius, and ε0 is the electric constant.

To find the radial distance at which the field is at its maximum, we can take the derivative of Em with respect to R and set it equal to zero:

\(dE_m/dR = -2(1/4\pi \psi_0) * (Q/R^3) = 0\)

Solving for R, we get:

\(R = (Q/(2\pi \psi_0E_m))^{1/2\)

Therefore, the radial distance at which the field is at its magnitude maximum Em is given by \(R = (Q/(2\pi \psi _0E_m))^{1/2\).

This is one of  the mysteries  of quantum mechanics - a  single photon in classical mechanics is sent out in a circular arc - but when the arc interacts with a distant object the entire wave front collapses and delivers the entire energy of the photon to the object in question.

An analogy has been give as a pop  bottle thrown into the water in New York with its energy spreading out in a circular arc and at some time later  the wave front strikes a pop bottle in the water in Japan with the result of the wave front delivering its entire energy to the bottle with the bottle jumping out of the water.

The magnitude of reaction at the beam due to the distributed load of 25 kN/m is 625 N.

The magnitude of reaction at the beam can be determined by calculating the total force exerted by the distributed load. In this case, the distributed load is given as 25 kN/m. To find the magnitude of reaction, we multiply the distributed load by the length of the beam.

Therefore, the magnitude of reaction is 25 kN/m multiplied by the length of the beam in meters. By performing the calculation, we obtain the value of 625 N as the magnitude of reaction at the beam due to the distributed load. This represents the total force exerted by the distributed load on the beam.

Heat transmission via conduction occurs when two items are in contact. Heat is transferred to the object with the lower temperature when two things touch and one of them has a higher temperature than the other. Because heat is transferred from the object to your hand when you contact with anything hot, it feels hot.

Convection is the process by which heat is transferred from one liquid or gas molecule to another as it moves in a circular motion in response to variations in temperature and density. For instance, the wax in the bottom of a lava lamp warms up and starts to melt when it is turned on. The wax begins to rise as the temperature rises and the density of the wax decreases. As it ascends, it moves further away from the heat source and begins to cool. It starts the process over as it cools, becoming denser and sinking.

Answer:

Explanation:

concepts used

force = mass* acceleration

equation of motion

\(v^2 = u^2 + 2as\)

where v is the final velocity

u is the initial velocity

and s is the distance moved

______________________________________________

Given

mass = 1 kg

initial velocity (u) = 40m/s

final velocity (v) = 0 as stones comes to rest

distance moved by stone (s) = 50m

using  \(v^2 = u^2 + 2as\)

\(0 = 40^2 +2a*50\\=> -1600 = 100a\\=> a = -1600/100 = -16\)

Thus, acceleration is -16 m/s^2

here acceleration is negative as force of friction is opposing the motion.

Force of friction = mass of stone * acceleration of stone

Force of friction = 1*-16 kgm/s^2 = -16N       ( kgm/s^2 = 1 N)

Thus, option c -16N is correct choice.

Answer:

Velocity = distance / time

V = 10/1

V = 10km/h

Answer:10km/h or 2.77m/s.

Explanation:

Distance =10km

Time =1h

Velocity =10/1 =10km/h

Or,

Distance =10km =10000m

Time =1h =60min = 3600s

Velocity =10000/3600 =2.77m/s

The momentum of the small rock at distance 2 is 1.08e+17 kg · m/s, in the -y direction.

What is momentum?

To solve this problem, we need to use the conservation of momentum. Since there are no other massive objects nearby, the total momentum of the system (rock + star) must be conserved.

At the first distance d1, the momentum of the rock can be split into two components: one in the x direction and one in the y direction. Using the angle α = 122 degrees, we can calculate the x and y components of the momentum:

p1x = p1 * cos(α) = 1.15e+17 kg · m/s * cos(122°) = -3.97e+16 kg · m/s

p1y = p1 * sin(α) = 1.15e+17 kg · m/s * sin(122°) = 1.08e+17 kg · m/s

Since there are no external forces acting on the system, the momentum in the x direction and the momentum in the y direction must be conserved separately. However, since the path of the rock is not given, we cannot assume that the momentum in the x direction is conserved. Therefore, we need to calculate the new momentum of the rock in the y direction at distance d2.

To do this, we can use the conservation of momentum in the y direction:

p1y = p2y

where p2y is the momentum of the rock in the y direction at distance d2.

We can rearrange this equation to solve for p2y:

p2y = p1y = 1.08e+17 kg · m/s

Therefore, the momentum of the small rock at distance 2 is 1.08e+17 kg · m/s, in the -y direction.

Binomial Expansion is a mathematical technique that involves expanding a given expression with two terms (binomial) raised to a power. It can be useful in solving complex mathematical problems, but finding the expansion of a binomial expression by hand can be time-consuming and error-prone.

Fortunately, modern calculators can help simplify this process by providing built-in functions for binomial expansion. The specific method for using a calculator to perform a binomial expansion will depend on the type of calculator you have, but here is a general explanation for how it can be done:

Make sure your calculator is in the correct mode: Before using your calculator for binomial expansion, you need to make sure it is in the correct mode. For most calculators, this is the "math" or "algebra" mode.

Choose the correct function: Most calculators have a function specifically designed for binomial expansion, often referred to as the "binomial theorem" or "nCr" function. This function calculates the individual terms of the binomial expansion.

Input the binomial expression: Enter the binomial expression you want to expand, including the power to which it is raised. For example, if you want to expand (a + b)^3, enter (a + b) and then "^" followed by the power, "3".

Use the binomial theorem function: Apply the binomial theorem function to the expression. This will give you the individual terms of the expansion.

Verify the expansion: Compare the expansion generated by your calculator to a known result or to a binomial expansion table to make sure the expansion is correct.

Note: Not all calculators have a built-in binomial theorem function, so you may need to use a different method or software to expand binomials.

In conclusion, using a calculator to perform a binomial expansion can save time and reduce the risk of calculation errors. The specific steps may vary depending on the type of calculator you have, but the general idea is to choose the correct function and input the binomial expression.
