A π bond is weaker than a σ bond because it involves a lesser degree of orbital overlap.

A π bond is a type of covalent bond formed by the sideways overlap of two atomic orbitals. It is generally weaker than a σ bond, which is formed by the end-to-end overlap of atomic orbitals. This is because the degree of orbital overlap in a π bond is lesser than that in a σ bond. In a π bond, the orbitals overlap partially, resulting in a bond that is weaker and more easily broken than a σ bond.

The strength of a bond is related to the degree of orbital overlap, and so π bonds are typically weaker than σ bonds. However, π bonds can still play important roles in chemical reactions and can contribute to the stability and reactivity of molecules.

The science of classifying living things is called taxonomy. Scientists classify living things in order to organize and make sense of the incredible diversity of life. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA.

Explanation:

The science of classifying living things is called taxonomy.

The temperature conversion formula between Fahrenheit (°F) and Celsius (°C) is as follows: °C = (°F - 32) x 5/9. This formula can be used to convert a temperature measured in Fahrenheit to its equivalent in Celsius.

To convert 45 °F to °C, we can substitute 45 for °F in the formula and perform the calculation:

°C = (45 - 32) x 5/9

°C = 13.33

So 45 °F is equivalent to 13.33 °C.

It's important to note that the Fahrenheit and Celsius scales are different and not directly comparable. The freezing point of water is 32 °F (0 °C) and the boiling point of water is 212 °F (100 °C) on the Fahrenheit scale. While on the Celsius scale, the freezing point of water is 0 °C and the boiling point of water is 100 °C.

An electrically charged object can be used to attract any object with an opposite charge.

This is due to the fundamental principle that opposites attract and repel in physics.

Electric charge is a fundamental property of matter that gives rise to electromagnetic interactions. An electric charge, whether positive or negative, produces an electric field that surrounds it. This field exerts a force on any other charge in its vicinity that is either attracted to or repelled from it. Electric charge is a fundamental property of matter that produces a variety of electric phenomena. When the charge is concentrated in a localized region of space, the object is electrically charged. When there is a net accumulation of charge in an object, it becomes electrically charged. An electrically charged object produces an electric field in its vicinity, which exerts a force on other charged objects. An electrically charged object can be used to attract objects with an opposite charge or repel objects with the same charge.

Explanation:

It is false to conclude that a light microscope with an objective lens numerical aperture of 0.65 is capable of allowing two objects 320 nm apart to be distinguished when using light with a wavelength of 420 nm.

Given,

Numerical aperture of lens = 0.65

Wavelength (λ) = 420 nm

Now,

0.61 × λ / numerical aperture = resolving power

Or, 0.61 × 420 / 0.65 =394.15 nanometers

Therefore, the least distance between two things that can be distinguished as two independent objects is 394.15 nm, which means two objects separated by 320 nm can not be distinguished as two separate objects with this microscope.

Hence, as a result, the statement is false.

Answer

the answer is A and c

Explanation:

i got it right on edge

Answer:

Both A and C is correct

Explanation:

Answer:

The drawdown in a confined aquifer under transient conditions can be estimated using the Theis solution for the non-equilibrium radial flow of water. This solution is given by:

s = Q / (4πT) * W(u),

where s is the drawdown, Q is the pumping rate, T is the transmissivity, and W(u) is the well function (also called the Theis function) which depends on the variable u, where:

u = r²S / (4Tt),

where r is the distance from the pumping well and t is the time since pumping began.

Given T = 2500 m²/day, S = 1.0 x 10-3, and Q = 500 m³/day, we can calculate the drawdown at 10 m (r1 = 10 m) and 50 m (r2 = 50 m) for t = 150 days.

For (i) r1 = 10 m:

u1 = r1²S / (4Tt) = (10 m)² * 1.0 x 10-3 / (4 * 2500 m²/day * 150 days) = 0.000667

s1 = Q / (4πT) * W(u1) = 500 m³/day / (4π * 2500 m²/day) * W(0.000667).

For (ii) r2 = 50 m:

u2 = r2²S / (4Tt) = (50 m)² * 1.0 x 10-3 / (4 * 2500 m²/day * 150 days) = 0.01667

s2 = Q / (4πT) * W(u2) = 500 m³/day / (4π * 2500 m²/day) * W(0.01667).

Explanation:

Unfortunately, the well function W(u) cannot be evaluated directly without more specialized knowledge or tools. The well function is related to the exponential integral function, which requires numerical computation. You would typically use a table of values, a calculator with this function, or a computer program to evaluate it. After obtaining W(u), multiply it by the remaining fraction to find the drawdowns.

Answer:

Explanation:

In physics, work can be described as force multiplied by the displacement of the object (distance caused by the force acted on the object).

Work is a form of energy, therefore, it is measured in joules.

If Alex pushed on an object with 10N of force, and the object moved 2 meters, the work of Alex will be equal to:

W = Ft

W = 10N * 2m

W = 20 Joules

But, if we have John, that pushed on an object with 2N of force, but, since the object was way smaller, therefore it had way less inertia, the object moved a distance equal to 10 meters. Let's also calculate his work.

W = Ft

W = 2N * 10m

W = 20 Joules

And we got the same result.

Work can also be used to calculate power.

Power is equal to P = Work / time

It can also be written as P = delta Work / delta time

Power is measured in joules per second.

With power you can make the difference between someone that got a 2 kg object up in 2 second, and someone that got a 2 kg object up in 5 second.

The more powerful one would be the one who managed to make the same work in less time.

Hope it Helped!

Work is described as: the measure of energy transfer resulting from the application of force over a displacement.

In the field of physics, work is most accurately defined as the outcome of multiplying the force exerted on an object by the distance the object is displaced in the same direction as the force.

This calculation serves to quantify the energy transferred to or from the object. For instance, if an individual applies a 50 Newton force to push a box across a 5-meter distance in the force's direction, the work done on the box would equal 250 Joules (50 N × 5 m).

Answer:That only applies to highly polished surfaces, eg mirrors.

If you take a high quality laser (ie with low divergence) and aim it at a wall, you can see the spot where the laser beam reaches the wall from anywhere with a direct line-of-sight to the spot where the laser beam reaches the wall. This due to micro imperfections on the surface of the wall. At a microscopic level, the wall surface is very rough and pointing in all directions.

As to why, a beam of light bounces of a highly polished surface, I can only surmise that it is essentially due to kinematics, ie the only force opposing the light beam is normal to the surface, hence there no forces along the reflective surface. Since there are no forces along the reflective surface, the speed component of light along the reflective surface remains unchanged. However, on the plane perpendicular to the reflective surface the, the light photons bounce off at the same speed at which the hit the reflective surface because the mass of the reflective surface is much much much larger than the mass of the photons, which means that the reflective surface won’t move at all. Since conservation of momentum requires that momentum after the collision be the same as the momentum before the collision then the only way for that to happen is if the velocity of the photon perpendicular to the reflective surface is of exactly the same magnitude but in the opposite direction. Vector resolution of the speed component of the reflected beam means that the angle of reflection must be the same as the angle of incidence.

The extra cost of fuel for driving 83 mph instead of 73 mph is $3.7671.

The speed of your automobile has a huge effect on fuel consumption. Traveling at 65 miles per hour (mph) instead of 55mph can consume almost 20% more fuel. As a general rule, for every mile per hour over 55 , you lose 2% in fuel economy.

If you take a 400-mile trip and your average speed is 83mph rather than the posted speed limit of 73mph, then the extra cost of the fuel is calculated as:

* **Fuel consumption at 83 mph:** 30 mpg * (1 - 2% * (83 - 55)) = 27.6 mpg

* **Fuel consumption at 73 mph:** 30 mpg * (1 - 2% * (73 - 55)) = 29 mpg

* **Extra fuel used:** 400 miles / 27.6 mpg - 400 miles / 29 mpg = 2.4 gallons

* **Extra cost of fuel:** $3.26/gallon * 2.4 gallons = $3.7671

Explanation:

(i) The generator delivers a greater rms current when only the resistor is present.

(ii) The greater average power is consumed by the circuit when both the inductor and the resistor are present.

The average power consumed in the inductor-resistor series circuit is 0.0216 A.

(i) In the case where both the inductor and the resistor are present, the generator delivers a greater rms current. This is because the presence of the inductor introduces reactance, which affects the overall impedance of the circuit. The reactance of an inductor is frequency-dependent, and since the generator has a frequency of 1160 Hz, the inductor will have a significant impact on the current flow. (ii) In the case where both the inductor and the resistor are present, the greater average power is consumed by the circuit. This is because the inductor introduces reactive power to the circuit, which does not contribute to useful work but rather oscillates between the inductor and the generator. Therefore, the combination of the resistor and the inductor results in a higher total power consumption compared to when only the resistor is present.

To calculate the average power consumed in the inductor-resistor series circuit, we need to determine the total impedance of the circuit and use it to calculate the average power.

Given:

Resistance, R = 495 Ω

Inductance, L = 0.085 H

Frequency, f = 1160 Hz

Average power consumed by the resistor, P_resistor = 0.25 W

First, we calculate the reactance of the inductor using the formula X_L = 2πfL:

X_L = 2π(1160 Hz)(0.085 H) ≈ 200.34 Ω

Next, we calculate the total impedance of the circuit using the resistance and reactance:

Z = √(R^2 + X_L^2) = √(495^2 + 200.34^2) ≈ 535.23 Ω

Finally, we can calculate the average power consumed in the inductor-resistor series circuit using the formula P = I^2Z, where I is the rms current:

P = I^2Z

0.25 W = I^2(535.23 Ω)

I^2 = 0.25 W / 535.23 Ω

I ≈ √(0.000468 A)

I ≈ 0.0216 A
