The number of pascal equivalent to 1 inch of mercury is 3386.53 pascal
From the question given above, we were told that:
29.92 inches of mercury = 1 atm
101325 pascal = 1 atm
Thus,
29.92 inches of mercury = 101325 pascal
With the above information, we can obtain the number of pascal equivalent to 1 inch of mercury. This can be obtained as follow:29.92 inches of mercury = 101325 pascal
Therefore,
1 inches of mercury = 101325 / 29.92
1 inches of mercury = 3386.53 pascalThus, the number of pascal equivalent to 1 inch of mercury is 3386.53 pascal

Explain Beryllium chloride molecule ( Formation of BF3 molecule and NH3 molecule )
Answer:
Here it is!
Explanation:
BeCl2 referred to as Beryllium Chloride, is an inorganic compound. It appears as white or yellow crystal solid at room temperature. It can exist in both monomeric and 1-D polymeric forms. The properties of beryllium chloride are similar to aluminum chloride owing to the diagonal relationship of beryllium with aluminum.
The molar mass and melting point of beryllium chloride are 79.91 g/mol and 399 °C, respectively. The chemical bonding in Beryllium Chloride is studied by writing down its Lewis structure by following the Lewis approach.
After lewis structure, there is a need of understanding its molecular geometry and hybridization of the central atom, Beryllium. The molecular orbital (MO) theory will be used to understand the MO diagram of beryllium chloride.
Pls rate 5 and mark as brainiest!
Answer:
Beryllium Chloride
[tex]{ \boxed{ \mathfrak{formula : \: { \rm{BeCl _{2} }}}}}[/tex]
Beryllium chloride is formed through ionic / electro-valent bonding. The beryllium atom loses its two valency electrons to the two chlorine atoms each with seven outermost electrons.
As a result, an ionic compound Beryllium chloride is formed.
Boron Fluoride (BF3)
Boron trifluoride is formed through interaction of π bonds with the double alpha bonds of fluorine.
From VESPR, the structure is tetrahedral and non-symmetrical hence polarity is high.
Since, fluorine is highly electronegative, it makes the bond polar
All in all, Boron Fluoride is formed through hybridization.
Ammonia (NH3)
Ammonia is formed through hydrogen bonding.
Hydrogen bonding is a covalent bonding situation where hydrogen bonds with a highly electronegative element such as oxygen, fluorine, nitrogen.
If the force exerted by the intern is doubled and the dis- tance is halved, does the work done by the intern increase, decrease, or remain the same?
If the force exerted by the intern is doubled and the distance is halved, the work done by the intern remains the same. Work done is the force applied to move a body through a distance.

A 4,000-kg wrecking ball is hoisted 20 m above Earth's surface. What will the wrecking ball's gravitational potential energy be?
Answer:
784,000 JExplanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
GPE = 4000 × 9.8 × 20 = 784,000

When a capacitor is charged, the electric field E, and hence the electric flux Φ, between the plates changes. This change in flux induces a magnetic field, according to Ampère's law as extended by Maxwell: ∮B⃗ ⋅dl⃗ =μ0(I+ϵ0dΦdt). You will calculate this magnetic field in the space between capacitor plates, where the electric flux changes but the conduction current I is zero. A parallel-plate capacitor of capacitance C with circular plates is charged by a constant current I. The radius a of the plates is much larger than the distance d between them, so fringing effects are negligible. Calculate B(r), the magnitude of the magnetic field inside the capacitor as a function of distance from the axis joining the center points of the circular plates. Express your answer in terms of μ0 and given quantities. B(r) =
The magnitude of the magnetic field B(r) inside the capacitor as a function of distance from the axis is [tex]\mathbf{B(r) =\dfrac{\mu_o I r}{2 \pi a^2} }[/tex]
A charged capacitor usually cause changes between the plates of electric field E and the electric flux Φ
As seen in Ampere's law which is extended by Maxwell:
[tex]\mathbf{\oint B^{\to} .dl^{\to} = \mu_o \Big( I+\dfrac{d \phi }{dt} \Big)}[/tex]
To meet the equilibrium equation of electric charge, Maxwell modified Ampere's law by incorporating the displacement current through into electric current component.
∴
The displacement current can be expressed by the relation;
[tex]\mathbf{I = \varepsilon_o \dfrac{dE}{dt} }[/tex]
From the given information, the displacement current density through area A can now be expressed as:
[tex]\mathbf{I = \varepsilon_o A \dfrac{dE}{dt} }[/tex]
Replacing the value of displacement current density into Maxwell modified Ampere Law, we have:
[tex]\mathbf{\oint B .dl= \mu_o I_{enclosed} }[/tex]
[tex]\mathbf{B \times (2 \pi r) = \mu_o I\Big (\dfrac{\pi r^2}{\pi a^2} \Big) }[/tex]
[tex]\mathbf{B(r) =\dfrac{\mu_o I r}{2 \pi a^2} }[/tex]

What is the Scientific name for Ectoparasites?
Ectoparasites are a taxonomically diverse group of organisms that infest the skin of human beings and other animals. Ectoparasitic arthropods and nematodes are similar in that an individual organism can produce skin lesions that are large enough to see with the unaided eye. Ectoparasitic infestations are often intensely itchy, causing considerable annoyance and discomfort. These conditions are often focally hyperendemic in impoverished communities, with a particularly high prevalence in vulnerable families, households, and neighborhoods.
Pediculosis (infestation by head and body lice) and scabies are found to some degree in all human populations, but myiasis (fly larva infestation), tungiasis (sand flea disease), and cutaneous larva migrans occur mainly in tropical and subtropical environments. Except for body lice, the organisms discussed in this article are not vectors of pathogenic microorganisms. In other words, most ectoparasites do not carry disease-causing agents; they are, instead, the direct cause of disease. Mortality is low, but the cumulative morbidity from the direct discomfort, secondary bacterial infections, and sequelae of those infestations and infections is considerable.
Despite the abundant presence of ectoparasitic infestations across human populations, biomedical science lacks firm evidence-based practices to reliably control these organisms. In addition, head lice and scabies are developing resistance to some chemical compounds employed to treat infested individuals, prevent spread, and control outbreaks.

Question:
A second set of data was obtained using thicker pieces of putty. Both sets of results are shown in graph 2. What is the relationship between the resistance and the thickness of the conducting putty?
The resistance of the thin wire is greater than the resistance of the thick wire because the thin wire has fewer electrons to carry the current. Therefore, for thinner pieces of conducting putty we have the larger resistance and for the thicker pieces of conducting putty we have the lower resistance.

Dada la información de la pregunta, el calor absorbido por el cobre es de 12513 J o 2990 calorías.
El calor ganado se obtiene de la relación;
H = mcdt
Dónde;
H = calor absorbido
m = masa
c = capacidad calorífica del cobre
Δt = cambio de temperatura
La capacidad calorífica del cobre es de 385 J / kg / ° C
Entonces;
m = 250 gramos o 0,25 kg
Δt = 150 ° C - 20 ˚C = 130 ˚C
H = 0,25 kg * 385 J / kg / ° C * 130 ˚C
