Power is the ratio of the heat entered into the refrigerator to the coefficient of performance of the refrigerator. The power required to run the compressor in Watts is 249.149 W.

What is Power?

Power is the ratio of the heat entered into the refrigerator to the coefficient of performance of the refrigerator.

Given the surface area of the interior of the refrigerator is

A= 4.3 m ²

The refrigerator is insulated by a material of  thickness

t =3.6 cm =0.036 m

The thermal conductivity of insulating material is

k =0.0300 J/m-s

The change in temperature inside the refrigerator and room temperature is

dT= (273.15 + 44.2) -(273.15 + 9.2) =35 K

The rate of heat entered the refrigerator.

[tex]Q=\frac{k\times A\times dT}{t}[/tex]

Substituting value into the equation, we get

Q =126.67 W

The coefficient of performance of the refrigerator is

[tex]COP=\dfrac{(273.15+9.2)}{(273.15+44.2)-(273.15+9.2)}[/tex]

COP = 8.07

As, work done by the motor is 6.3% of the theoretical maximum,

[tex]\dfrac{6.3\times8.07}{100} =0.50841[/tex]

After encountering another ‘syntax error’ a disgruntled programmer throws a mouse perpendicular to the ground and it explodes into 3 pieces. A 100 g piece travels at 1.2 m/s, and a 30 g piece travels at 0.80m/s. The third piece flies off at a speed of 0.75 m/s. If the angle between the first two pieces is 120 degrees calculate the momentum and direction of the third piece with respect to the 100 g piece.

Answers

The momentum and direction of the third piece with respect to the 100 g piece is 0.11 kgm/s at 11 degrees.

Conservation of linear momentum

The momentum and direction of the third piece with respect to the 100 g mass is determined by applying the principle of conservation of linear momentum.

Pi = Pf

where;

Pi is initial momentumPf is final momentum

0 = P₁ + P₂ + P₃

where;

P₁ is final  momentum of the first pieceP₂ is final momentum of the second pieceP₃ is final momentum of the third piece

-P₃ = P₁ + P₂

-P₃x = P₁cosθ + P₂Cosθ  --(1)

-P₃y =  P₁sinθ + P₂sinθ  --(2)

-P₃x = (0.1 x 1.2 x cos0) + (0.03 x 0.8 x cos120)

-P₃x = 0.12 - 0.012

-P₃x = 0.108 kgm/s

P₃x = -0.108 kgm/s

-P₃y =   (0.1 x 1.2 x sin0) + (0.03 x 0.8 x sin120)

-P₃y =  0.0208 kgm/s

P₃y =  -0.0208 kgm/s

Resultant momentum of third piece

[tex]P_3 = \sqrt{P_3x^2 + P_3y^2} \\\\P_3 = \sqrt{(-0.108)^2 + (-0.0208)^2} \\\\P_3 = 0.11 \ kgm/s[/tex]

Direction of third piece

[tex]tan \ \theta = \frac{P_3y}{P_3x} \\\\\theta = tan^{-1} (\frac{P_3y}{P_3x} )\\\\\theta = tan^{-1} (\frac{-0.0208}{-0.108} )\\\\\theta = 11\ ^0[/tex]

Which transition by an electron will release the greatest amount of energy? a b c d

Answers

The electron of orbital a by transition will release the greatest amount of energy.

What is transition energy?

Atomic electron transition is a change (or jump) of an electron from one energy level to another within an atom or artificial atom.

It appears discontinuous as the electron "jumps" from one quantized energy level to another, typically in a few nanoseconds or less.

It is also known as an electronic (de-)excitation or atomic transition or quantum jump.

Electron transitions cause the emission or absorption of electromagnetic radiation in the form of quantized units called photons. Their statistics are Poissonian, and the time between jumps is exponentially distributed.

The damping time constant (which ranges from nanoseconds to a few seconds) relates to the natural, pressure, and field broadening of spectral lines.

The larger the energy separation of the states between which the electron jumps, the shorter the wavelength of the photon emitted.

Answers

Answer:

Explanation:

distance(d)= speed(v)* time(t)

calculate speed:

refractive index = speed of light (c)/ speed of light in medium (v)

1.56 = 3*10^8*v

v=192307692.3 m/s

d = v *t

t = d/v

A 70kg bicyclist (including the bicycle) is pedaling right with a constant speed despite
experiencing a 50N drag. Neglect any friction impeding her motion.
What is the magnitude of the net force on the bicyclist?
How much force is her pedaling generating?

Answers

Answer:There are total four forces acting on the bicyclist namely, gravitational force, normal force, pushing force and air drag.

The magnitude of net force acting on the bicyclist is 165 N.

The required magnitude of force generated for the pedaling is of 225 N.

Given data:

The mass of bicyclist is, m = 75.0 kg.

The magnitude of acceleration is, .

The magnitude of drag force is, F = 60.0 N.

(1)

There are in total 4 forces acting on the bicyclist:

The gravitational force on the bicyclist, acting vertically downward, of magnitude , where m is the mass of the bicyclist and g is the acceleration due to gravityThe normal force exerted by the floor on the bicyclist and the bike, N, vertically upward, and of same magnitude as the gravitational forceThe force of push F", acting horizontally forward, given by the push exerted by the bicyclist on the pedalsThe air drag, F, of magnitude F = 60.0 N, acting horizontally backward, in the direction opposite to the motion of the bicyclist

(2)

The magnitude of net force acting on the bicyclist is given as,

Thus, the magnitude of net force acting on the bicyclist is 165 N.

(3)

We need to find the forward force of push, F'', which is actually the force generated during pedaling.

Then the expression for the forward pushing force F" is given as,

Thus, we can conclude that the force  generated for the pedaling is of 225 N.

Explanation:

The magnitude of the net force on the bicyclist was 0 N.

Her pedaling is generating  a force of  50 N in opposite of the drag force .

What is force?

Force is defined in physics as: the push or pull on an object with mass that causes it to change velocity. Force is an external agent that can change the state of rest or motion of a body. It has a magnitude as well as a direction.

A spring balance can be used to calculate force.

As the bicyclist (including the bicycle) is pedaling right with a constant speed, the magnitude of the net force on the bicyclist was = mass × acceleration

= 70 kg × 0 m/s²

= 0 N.

Again her pedaling is generating  a force = drag force = 50 N in opposite of the  drag force . So that, net force on it becomes zero.
