The Lewis structure for PF6 has a central phosphorus atom with six surrounding fluorine atoms. Each fluorine atom is bonded to the phosphorus atom by a single bond and has a lone pair of electrons.
PF6 is a polyatomic ion, which means it has a charge. In this case, the charge is -1. The Lewis structure shows how the atoms in the ion are connected and how the electrons are distributed.
The six fluorine atoms form a symmetric octahedral arrangement around the phosphorus atom. Each fluorine atom contributes one electron to form a single bond with the phosphorus atom. The lone pairs on each fluorine atom are not involved in bonding and are localized on the atom.

Find the area of the surface generated when the given curve revolved about the x-axis.y=8√xon [9,20]
The area of the surface generated is approximately 1180.89 square units.
To find the area of the surface generated when the curve y = 8√x is revolved about the x-axis, we can use the formula:
[tex]A = 2\pi \int_a^b y ds[/tex]
where a and b are the limits of integration, y is the function to be revolved, and ds is an element of arc length.
To find ds, we can use the formula:
[tex]ds = \sqrt{1 + {(\dfrac{dy}{dx}})^2} dx[/tex]
where dy/dx is the derivative of y with respect to x.
In this case, we have y = 8√x,
So dy/dx = 4/√x.
Therefore, [tex]ds = \sqrt{1 + \dfrac{4}{\sqrt{x}}^2} dx[/tex]
[tex]= \dfrac{4}{\sqrt x} \times \sqrt{x+4}\ dx[/tex]
Substituting this into the formula for the surface area, we get:
[tex]A = 2\pi \int_9^{20} y \times 4/√x \times \sqrt{x+4} dx\\= 8\pi \int_9^{20} \sqrt x \times \sqrt{x+4}\ dx\\= 8\pi \int_9^{20} (x+4) dx\\= 8\pi [\dfrac{1}{2}\times (20^2+420) - \dfrac{1}{2}\times (9^2+49)][/tex]
= 1180.89
Therefore, the area of the surface generated is approximately 1180.89 square units.

What is the acceleration of gravity on Mercury?
The acceleration of gravity on Mercury is approximately 3.7 meters per second squared (m/s^2). This value is determined by the mass of Mercury and the distance between its center of mass and the surface of the planet. Because Mercury is smaller and less massive than Earth, the force of gravity on its surface is weaker, leading to a lower acceleration of gravity.

Impulse problem. The PC has plotted the force applied by the force transducer to the car. In principle, the proper way to use this information is to integrate the transducer signal to obtain F dt. This could be done numerically by the computer but would be of little educational value. Instead, we use an approximate technique often used in practice. Assume the signal looks like the one in Figure 5.4. Then the impulse can be approximated by LaTeX: \int∫ Fdt=Fmax LaTeX: \DeltaΔt, where Fmax is the maximum force and LaTeX: \DeltaΔ t is the Full Width Half Maximum (FWHM) of the signal. Theoretically, LaTeX: \int∫ F dt = LaTeX: \DeltaΔ p. Use the above graph to compute the impulse in kgm/s. Please express your answers with 1 decimal place. _______________________________kgm/s
When the maximal force and Full Width Half Maximum (FWHM) of the signal are combined, impulse would be roughly: if Fmax is 1000 N, and t is 0.1 s.
the result is in newton-seconds (Ns) or kilogrammes per second (kg/s), and is used to approximate the impulse.
I am unable to give a precise response without access to Figure 5.4. However, depending on the data given, the impulse can be roughly described as:
Fmax x t Impulse
where t is the Full Width Half Maximum (FWHM) of the signal and Fmax is the maximum force.
You must convert the force units to newtons and the time units to seconds before multiplying the two values to obtain the impulse in kilogrammes per second (kgm/s). The outcome will be expressed in newton-seconds (Ns) or kgm/s.
For instance, the impulse would be roughly: if Fmax is 1000 N, and t is 0.1 s.

Two children have identical spring-loaded catapults, which contain springs with spring constant k. If Samir compresses the spring in his catapult by a distance x and Mona compresses hers by a distance 2x, hovw does the work they have done to compress their catapults compare?
The work done by Samir and Mona to compress their catapults is (1/2) kx^2 joules and kx^2 joules respectively. hence, the work done by Mona is twice the work done by Samir.
The work done by Samir and Mona to compress their catapults is proportional to the amount of energy stored in the springs. The energy stored in the spring is given by the formula:
E = (1/2) kx^2
where E is the energy stored in the spring, k is the spring constant, and x is the distance the spring is compressed.
Therefore, the work done by Samir to compress his spring by a distance x is:
W1 = (1/2) kx^2
And the work done by Mona to compress her spring by a distance 2x is:
W2 = (1/2) k(2x)^2 = 2(1/2) kx^2 = kx^2
So, the work done by Mona is twice the work done by Samir. Mona has compressed her spring by twice the distance that Samir has compressed his spring, so she has stored twice the amount of energy in her spring. This means that she has done twice the amount of work as Samir to compress her spring.

Kinetic Energy of a body: This is the energy of a body i motion. It is measured in Joules.
It can be expressed mathematically as
Ke = 1/2mv²................................... equation 1
Where ke = kinetic energy, m = mass in kg, v = velocity in m/s.

In proton coupling, the J-value of a coupled proton is always less than that of the 'parent' proton. Therefore, since Proton A has a J-value of 3.0 Hz, Proton B will have a J-value less than 3.0 Hz.
What is Proton Coupling?Proton coupling is a type of nuclear magnetic resonance (NMR) technique used to determine the structure of molecules. It involves the use of radio frequency pulses to excite and measure the magnetization of protons in a sample. The technique is used to measure the distances between protons, as well as the tumbling motion of molecules, which can be used to assign chemical shifts and atom connectivity. Proton coupling can also be used to measure the concentration of protons in a sample, which can provide insight into the structure and properties of the molecules.
When two protons are coupled together, the J-value of the coupled proton is always less than that of the parent proton. This is because the total energy of the system is conserved, and the energy of the coupled proton is reduced as it shares its energy with the parent proton. This reduced energy is reflected in the lower J-value of the coupled proton. Therefore, since Proton A has a J-value of 3.0 Hz, Proton B will have a J-value less than 3.0 Hz.

calculate the height of the mercury in the tube above the surface in the trough. (Take air pressure = 1.0*1.0^5 pa & density of mercury = 136000 kg/m^3)
Answer:
Explanation:
To calculate the height of the mercury in the tube above the surface in the trough, we can use the following formula:
h = (P - P<sub>0</sub>) / ρg
where h is the height of the mercury column, P is the pressure at the bottom of the tube, P<sub>0</sub> is the atmospheric pressure, ρ is the density of the mercury, and g is the acceleration due to gravity.
Since the pressure at the bottom of the tube is due to the weight of the mercury column above it, we can also express P as P = ρgh, where h is the height of the mercury column in the tube.
Substituting this expression for P into the formula above, we get:
h = (ρgh - P<sub>0</sub>) / ρg
Simplifying this expression, we get:
h = h - P<sub>0</sub> / g
Solving for h, we get:
h = P<sub>0</sub> / ρg
Substituting the given values, we get:
h = (1.0 x 10<sup>5</sup> Pa) / (136000 kg/m<sup>3</sup> x 9.81 m/s<sup>2</sup>)
h = 0.073 m
Therefore, the height of the mercury in the tube above the surface in the trough is approximately 0.073 meters.

Power may be characterized as the total amount of energy that is transferred or converted per unit of time. The SI Unit of power is Watt.
How power is related to voltage?Power is the product of voltage and current. With an electronic circuit, the amperage is the amount of electric charge that flows through the wire, while the voltage is the amount of electric potential within a circuit.
By multiplying the voltage times the ampere, you can see how much energy can flow through the circuit. The energy, or power, is measured in watts.
Power in Watts is calculated by multiplying voltage in Volts times current in Amps: 10 Amps of current at 240 Volts generates 2,400 Watts of power. This means that the same current can deliver twice as much power if the voltage is doubled.
