Answer:

Mechanical energy :)

Explanation:

In order for energy to be conserved, the energy released must be equal to heat energy lost in the process.

The principle of conservation of energy states that, the total energy in a system is always conserved.

M = P.E + K.E

where;

Thus, in order for energy to be conserved, the energy released must be equal to heat energy lost in the process.

Answer:

(4x - 1) (x - 7)

Explanation:

4x^2 - 29x + 7 = 0

(4*-7=-28) and: (1*- 1 = -1)

-28 - 1 = -29 and - 1 times -7 = 7

Answer:  Gravity is the force that keeps planets in orbit around the Sun. Gravity alone holds us to Earth's surface.

Planets have measurable properties, such as size, mass, density, and composition. A planet's size and mass determines its gravitational pull.

A planet's mass and size determines how strong its gravitational pull is.

Models can help us experiment with the motions of objects in space, which are determined by the gravitational pull between them.

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.

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.

Answer:

THE ANSWER IS B.

Explanation:

Answer:

t = V0 sin theta / g      time to get max height

h = Voy t - 1/2 g t^2 = Vo^2 sin^2 theta / 2 g          max height

R = V0^2 sin 2 theta / g      range formula

h = 3 R        given

Vo^2 sin^2 theta / 2 g = 3 * V0^2 sin 2 theta / g

sin^2 theta = 6 * sin 2 theta = 12 * sin theta cos theta

tan theta = 12

theta = 85.2 deg

Can check:  

Vx = 8.37

Vy = 99.6     assuming V0 =100

t = 99.6 / 9.8 = 10.2 sec     to reach max height

Sx (total range) = 2 * 10.2 * 8.37 = 170 m

Sy = 1/2 * 9.8 * (10.2)^2 = 510 m

Height = 3 * range

To compare the magnitude of the inertia of the bowling and tennis ball, we take the ratio of their masses. Hence, the bowling ball has 100 times the inertia of the tennis ball.

Given the Parameters :

Taking the ratio of the masses :

Inertia = 6kg / 0.06kg

Inertia = 100

Hence, the inertia of the bowling ball is 100 times that of the tennis ball.

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.

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]

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
