The range of electronegativity for polar nonpolar and ionic bonding is less than 0.4 and greater that 0.4, respectively.
In general there are two major categories of bonds, which are polar molecules and nonpolar molecules.
In the field of chemistry, polarity can be described as the distribution of electric charge around atoms, chemical groups, or molecules.
When there is an electronegativity difference between the bonded atoms then polar molecules are formed. Water - \(H_{2}\)O, Ammonia - N\(H_{3}\) are some of the examples of polar molecules.And when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel out each other then non polar molecules are formed. Any of the noble gasses: He, Ne, Ar, Kr, Xe, Benzene, methane etc are some of the examples of the molecules which forms non polar bondAnd if we talk about ionic bond, which are also be called as electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. These types of bond forms when the outermost electrons of one atom are transferred permanently to another atom.There is no hard and fast rule but in general, a bond is considered as non polar if the difference in electronegativities is less than about 0.4, and it will be called a polar bond molecule if the difference is greater than 0.4.

a stone of mass 750 kg is thrown vertically upward with a velocity of 10m/s find the potential energy at the greatest height and kinetic energy on reaching the ground
Answers
Answer:
Potential Energy at the greatest point = 37.5 J
Explanation:
Given :
Mass is 750 g
In term of kg :
Mass is 0.75 kg .
Velocity ( v ) = 10 m / sec
We have formula for kinetic energy :
K.E. = 1 / 2 m v²
Putting values now :
K.E. = 1 / 2 × 0.75 × 10 × 10
K.E. = 1 / 2 × 75 J
K.E. = 37.5 J
Since K.E . = P.E.
Thus potential energy of stone is 37.5 J .

A wave has a wavelength of 4.9 m and a velocity of 9.8 m/s. The medium through which this wave is traveling is then heated so that the velocity is doubled. If the frequency remains constant, what is the wavelength of the heated wave? 2.5 m 9.8 m 14.7 m 19.6 m
Answers
Answer:
the wavelength is 9.8 meters
Explanation:
We can use the relationship:
Velocity = wavelenght*frequency.
Initially we have:
wavelenght = 4.9m
velocity = 9.8m/s
then:
9.8m/s = 4.9m*f
f = 9.8m/s/4.9m = 2*1/s
now, if the velocity is doubled and the frequency remains the same, we have:
2*9.8m/s = wavelenght*2*1/s
wavelenght = (2*9.8m/s)*(1/2)s = 9.8 m

you have a 1.30-m-long copper wire. you want to make an n-turn current loop that generates a 0.700 mt magnetic field at the center when the current is 1.20 a . you must use the entire wire.
Answers
The magnetic field generated by a current loop is given by the equation:
B = (μ0 * n * I * A) / (2 * R)
where μ0 is the permeability of free space (4π x 10^-7 T·m/A), n is the number of turns, I is the current, A is the area of the loop, and R is the distance from the center of the loop to the point where the magnetic field is measured.
In this case, we want to make a loop with a length of 1.30 m, so the circumference of the loop will be C = 2πr = 1.30 m, where r is the radius of the loop. Solving for r, we get:
r = C / (2π) = 1.30 m / (2π) = 0.2077 m
The area of the loop is given by A = πr^2, so:
A = π(0.2077 m)^2 = 0.1358 m^2
Now we can plug in the values given and solve for the number of turns:
0.700 T = (4π x 10^-7 T·m/A) * n * 1.20 A * 0.1358 m^2 / (2 * 0.2077 m)
Solving for n, we get:
n = (0.700 T * 2 * 0.2077 m) / [(4π x 10^-7 T·m/A) * 1.20 A * 0.1358 m^2]
n = 147.4 turns
Therefore, you need to make a current loop with 147 turns to generate a 0.700 mT magnetic field at the center of the loop using the entire 1.30 m long copper wire.

How long would it take to swim across a lake that is 350 meters, if you swam at 9 m/sec
Answers
Answer:
\(\boxed {\tt t\approx 38.89 \ s}\)
Explanation:
Time can be found by dividing the distance by the speed.
\(t=\frac{d}{s}\)
The distance is 350 meters.
The speed is 9 meters per second.
\(d= 350 \ m \\s= 9 \ m/s\)
Substitute the values into the formula.
\(t=\frac{350 \ m}{9 \ m/s}\)
Divide. Note that the meters or "m" will cancel each other out and the seconds or "s" will move to the numerator.
\(t=\frac{350 }{9 \ s}\)
\(t=\frac{350 \ s}{9}\)
\(t=38.8888889 \ s\)
Round to the nearest hundredth. The 8 in the thousandth place tells us to round the 8 to a 9.
\(t \approx38.89 \ s\)
It will take about 38.89 seconds to swim 350 meters at 9 meters per second.

Gravity causes cast of gases to clump together to begin forming new stars and planets.
Gravity binds the gas and dust together. If the cluster is large enough, it produces a star—increased pressure from gravitational collapse boosts the temperature, forcing nuclear fusion to occur in its center.
The dust and gases in a nebula are widely dispersed, yet gravity can gradually bring clumps of dust and gas together. As these clusters grow in size, their gravity grows stronger and stronger. The clump of dust and gas eventually becomes so large that it collapses due to its own gravity.

option A.
What is the direction of light?
Light travels in straight lines unless it is reflected, refracted, or absorbed by a material. When light passes through a material, such as a window, it can be transmitted (pass through the material), reflected (bounce off the material), or refracted (bend as it passes through the material).
In the case of the airplane window, it is designed to be transparent, which means that it allows most of the light hitting it to pass through, without significant absorption or reflection. This is because the window is made of a material that is highly transparent to visible light, such as glass or acrylic.
Thus, the reason Susan could see the clouds through the window of the airplane is that the window was made of materials that allow most of the light hitting it to pass through, which is called transmission.

Review. A light source emitting radiation at frequency 7.00 × 10⁻¹⁴ Hz is incapable of ejecting photoelectrons from a certain metal. In an attempt to use this source to eject photoelectrons from the metal, the source is given a velocity toward the metal.(a) Explain how this procedure can produce photoelectrons.
Answers
The procedure of giving a velocity to a light source emitting radiation at frequency 7.00 × 10⁻¹⁴ Hz toward a certain metal can produce photoelectrons by increasing the effective energy of the photons, allowing them to transfer enough energy to eject electrons from the metal's surface.
When a photon interacts with an atom or a metal surface, it can transfer its energy to an electron, potentially ejecting it from the metal. The energy of a photon is directly proportional to its frequency, given by the equation E = hf, where E represents the energy of the photon, h is Planck's constant (6.626 × 10⁻³⁴ J·s), and f is the frequency of the photon.
In this scenario, the frequency of the light source (7.00 × 10⁻¹⁴ Hz) is not sufficient to overcome the metal's work function, which is the minimum energy required to eject an electron. By giving the light source a velocity toward the metal, a phenomenon called the Doppler effect occurs. The relative motion between the source and the metal causes a change in the observed frequency of the emitted radiation.
Due to the Doppler effect, the frequency of the radiation observed by an observer at rest relative to the metal increases. As a result, the effective energy of the photons also increases, potentially reaching or surpassing the work function of the metal. This allows the photons to transfer enough energy to the electrons in the metal, causing photoemission and the ejection of photoelectrons.
By providing the light source with a velocity toward the metal, the procedure enhances the energy of the photons, enabling the possibility of ejecting photoelectrons from the metal's surface.

Answers
Explanation:
this is the ans hope it works
Answer:
Forces make things speed up (or accelerate). When a force pushes or pulls the object, the object will move in the direction of the force. The bigger the force, and the lighter the object, the greater the acceleration.
Explanation:
The action from a force can cause an object to move or speed up (accelerate), to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it can be said that a force on an object results in the acceleration of an object.
A simple mathematical relationship exists between the mass of an object (m), the net force on the object (f) and its acceleration (a). The acceleration of an object is directly proportional to the net force and indirectly proportional to the object’s mass (a = f/m).

two solenoids are made with the same cross sectional area and total number of turns. inductor b is twice as long as inductor a;
Answers
Answer:
If two solenoids have the same cross-sectional area and total number of turns, but one is twice as long as the other, then the inductance of the longer solenoid will be greater than that of the shorter one.
The inductance of a solenoid is given by the formula:
L = (μ * n^2 * A * l) / (2 * l + d)
where L is the inductance in henries, μ is the permeability of the core material, n is the number of turns, A is the cross-sectional area, l is the length of the solenoid, and d is the diameter of the solenoid.
Since the two solenoids have the same cross-sectional area and total number of turns, we can simplify the formula for inductance as follows:
L = (μ * n^2 * A * l) / (2 * l + d) = (μ * n^2 * A) / (2 + d/l)
Since the cross-sectional area and total number of turns are the same for both solenoids, we can write:
Lb / La = (μ * n^2 * A * lb) / (2 * lb + db) / (μ * n^2 * A * la) / (2 * la + da)
Simplifying and rearranging, we get:
Lb / La = (2 * la + da) / (2 * lb + db)
Since inductor B is twice as long as inductor A, we have lb = 2la. Substituting this in the above equation, we get:
Lb / La = (2 * la + da) / (4 * la + db)
Since the cross-sectional area and total number of turns are the same for both solenoids, we have A and n^2 as common factors on both sides of the equation. Cancelling these out, we get:
Lb / La = (2 * la + da) / (4 * la + db)
= 2 * (la + da/2) / 4 * (la + db/4)
= (la + da/2) / (2 * la + db/2)
Now, since we know that inductor B is twice as long as inductor A, we have db = 2da. Substituting this in the above equation, we get:
Lb / La = (la + da/2) / (2 * la + db/2)
= (la + da/2) / (2 * la + da)
= 1 / 2 + (1 / 4) * (da / la)
Therefore, we can see that the inductance of inductor B is greater than inductor A by a factor of (1 / 2) + (1 / 4) * (da / la), which is always greater than 1. Hence, the inductance of the longer solenoid is greater than that of the shorter one.
