We are going to focus on the gravitational force between Earth and our Moon. The Earth has a mass of about 6 x 10/24 kg and the Moon has a
mass of about 7.3 x 10/22 kg. They are also currently about 4 x 10/8 meters apart.

The gravitational constant, G, is 6.67 x 10-/11 as always.

Question 1
If you were to weight yourself in the moon and the Earth, which would have the higher weight?

Answer:

the most elliptical orbit is that of COMETA

Explanation:

The eccentricity of a curve in defined as the ratio between lacia to the focus, called c and the value of the axis greater than

         ε = c / a

if we use Pythagoras' theorem

         c = [tex]\sqrt{a^2 - b^2}[/tex]

   substituting

           ε = [tex]\sqrt{1 - (b/a)^2 }[/tex]

if   ε = 0 we have a circumference

In the diagram presented the orbit of the comet is an ellipse a> b

          ε=[tex]\sqrt{1- x} \\ x = (\frac{b}{a} )^2[/tex]

if we expand in series

             ε = 1 - x/2  

             ε=  [tex]1 - \frac{1}{2} \ (\frac{ b}{a} )^2[/tex]

if we neglect the non-linear terms

            ε = 1

Earth's orbit is a small ellipse

             b / a = 149 10⁶ / 151 10⁶

             b / a = 0.98675

             ε = [tex]\sqrt{1- 0.98675^2}[/tex]

               ε = 0.16

a very small ellipse

Planet X, despite not having data, it seems that the sun is in the scepter of the orbit, so b = a

therefore  both the semi-axes of the curve

        e = a / b

Consequently, the most elliptical orbit is that of COMETA.

Friction

Explanation:

In the event that the power is applied toward the path inverse to the bearing of movement, it goes against the movement of the item and henceforth the speed of the article diminishes.

Then, in the event that the thing continues to move one way, grinding will dominate and go about as the moving variable.

So, the moving factor would be friction.

Density=mass/volume

Density=7.5/2.5

density=3g/cm^3

The density of a 2.5-cm3 glass marble that has a mass of 7.5 g is 3g/cm^3.

The density of a material is the measure of how tightly it is packed together. It is expressed as mass per unit volume.

Density Symbol: D or Density Formula: = m/V, where is the density, m is the object's mass, and V is the object's volume.

Density is the amount of "stuff" in a given amount of space. A block of the heavier element lead (Pb), for example, will be denser than a block of the softer, lighter element gold (Au). A Styrofoam block is less dense than a brick. It is expressed in terms of mass per unit volume.

Density = mass / volume

Density = 7.5 / 2.5

density = 3g/cm^3

Thus, The density of a 2.5-cm3 glass marble that has a mass of 7.5 g is 3g/cm^3.

Answer: due to large momentum

Explanation:

The impact of the loaded truck is very large on a body coming in its way because of the momentum associated with truck. Truck has a huge mass which is responsible for its large momentum.

Momentum is the product of mass and velocity. Even though the velocity of truck is low but it's mass compensates for it to give large momentum. This large momentum can overwhelm any small body at rest or coming in its way.

Answer:

f = 459.8 Hz

Explanation:

When a trumpet is playing it is an open tube at both ends, therefore there is a belly in each one, the resonance occurs to

           λ = 2L             1st harmonic

           λ = 2L /2        2nd harmonic

           λ = 2L /3       3rd harmonic

the speed of the wave is

           v = λ f

           λ = v / f

we substitute in the third harmonic

            [tex]\frac{v}{f} = \frac{2L}{3}[/tex]            (1)

            L = [tex]\frac{3}{2} \ \frac{v}{f}[/tex]

            L = [tex]\frac{3}{2} \ \frac{343}{ 510}[/tex]

            L = 1.009 m

indicates that to  add ΔL = 0.110 m, so the total length is

            L_total = L + ΔL

            L _total = 1.009 + 0.110

            L _total = 1,119 m

we use equation 1

            f =  [tex]\frac{3}{2} \ \frac{v}{L_{total}}[/tex]

            f = [tex]\frac{3}{2} \ \frac{343}{1.119}[/tex]

            f = 459.8 Hz

Answer:

La principal diferencia que existe entre la marcha cuando caminamos y cuando corremos, sea con o sin el balón, es la velocidad: al caminar, la velocidad es mucho menor que al correr, y a su vez, correr sin el balón da la posibilidad de correr mucho más rápidamente, debido a que no se requiere una coordinación entre los pasos y el control del balón.

Por otra parte, además de la velocidad, el ritmo cardiaco que se adquiere al caminar es mucho mas bajo que al correr, donde por causa del esfuerzo se aceleran las pulsaciones, aumentando la frecuencia cardiaca y, por lo tanto, la exigencia cardiovascular.

The process that is the source of all the thermal energy produced by a nuclear reactor is nuclear fission. The correct option is C.

The process by which an atom's nucleus divides into two daughter nuclei in nuclear physics. Fission, the splitting of uranium atoms, is the source of nuclear energy.

This produces heat that creates steam, which a turbine generator uses to produce power. A type of energy emitted by an atom's nucleus, which is composed of protons and neutrons, is known as nuclear energy.

Fission, which occurs when atom nuclei split into several pieces, and fusion, which occurs when nuclei combine, are the two methods by which this type of energy can be created.

Therefore, the correct option is C. Nuclear fission.

The term cell is incorrect because, the average voltage of a cell is 3.40 V and as already mentioned in question, the volt of source is 18 V, so cell couldn't be the appropriate word, actually the source is battery.

Now, the source is most likely related to cell because a battery which is the source here, is made up of a "group of cell".

Answer:

A. The waves in the water travel faster and at a higher frequency than they travel on land.

Explanation:

The main reason why human ears can hear dolphins' vocalizations while under the water but cannot hear them well on land is because water is denser than air and air particles travel faster in denser particles.

Denser particles also ensures that the frequency of the waves move faster which in turn produces a faster and louder result.

Answer:

4. Sterilization

Explanation:

A reservoir refers to the breeding ground or natural habitat of micro living organisms such as bacterias, fungi, worms, etc. Thus, a reservoir hosts or harbours pathogens and usually serves as a source of infection to other living organisms.

On the other hand, a source of infection refers to a contaminated material from which a disease can be acquired by another living organism.

Pathogen refers to a disease causing organism or substance such as fungi, protozoa, bacteria, virus, etc.

Sterilization simply means to be free from all organisms either pathogenic or nonpathogenic organisms such as spores and viruses.

An autoclave can be defined as a chamber (container) designed to expose an equipment to steam i.e a moisture at high heat and pressure for a specific period of time.

Basically, an autoclave is a container or chamber that is strongly heated and as a result, it is typically used for the sterilization of various laboratory and medical equipments using steam under pressure and high temperature.

This ultimately implies that, an autoclave avails laboratory scientist and other end users the ability to disinfect or sterilize equipments by exposing them to moisture at high heat and pressure for a specific period of time.

Answer:

La velocidad media en el trayecto completo es 0.8 [tex]\frac{km}{minutos}[/tex].

Explanation:

La velocidad es una magnitud física que expresa la relación entre el espacio recorrido por un objeto y el tiempo empleado para ello.

En otras palabras, la velocidad es una magnitud que relaciona el cambio de posición (o desplazamiento) con el tiempo.

La velocidad media resulta del cociente entre el desplazamiento seguido por un móvil y el  tiempo transcurrido que se emplea  para realizar dicho desplazamiento:

[tex]velocidad=\frac{desplazamiento}{tiempo}[/tex]

En este caso, un repartidor de comida rápida entrega una pizza a una casa que se encuentra a 20 km de distancia y se demora 20 minutos en llegar. De vuelta a la pizzería vuelve más relajado y se demora media hora. Entonces, el desplazamiento total entre la pizzería y la casa será 40 km, considerando que se dirige a la casa y vuelve a la pizzería.

Por otro lado, el tiempo total será el tiempo en que se dirige a la casa y luego vuelve a la pizzería, es decir 20 minutos + 30 minutos= 50 minutos.

Entonces:

[tex]velocidad=\frac{40 km}{50 minutos}[/tex]

Resolviendo:

velocidad= 0.8 [tex]\frac{km}{minutos}[/tex]

La velocidad media en el trayecto completo es 0.8 [tex]\frac{km}{minutos}[/tex].

Explanation:

I. The electric circuit shown is series and parallel resistor connection type.

II. The ratio of current in the 8-ohm resistors to the current in the 4-ohm resistors is 0.46.

III. The current in 8 ohm is less than the current in 4 ohm resistor.

IV. The ratio of current in the 3-ohm resistors and 8-ohm resistor to the current in the 10-ohm resistors is 1.

V. The current in 3 ohm and 8 ohm resistor is same.

The current is the total amount of charge flowing in the circuit per unit time.

3 ohm and 8 ohm resistor are in series which in turn parallel with the 10 ohm resistor.

The equivalent resistance of 3, 8 and 10 ohm resistor is in series with 9 an 4 ohm resistors.

I. The circuit consists of resistances connected in parallel and series also.

II.  The equivalent resistance of 3, 8 and 10 ohm resistor is [(3+8)x10/(3+8+10)] = 5.23 ohms.

Total equivalent resistance is 9 + 5.23 +4 = 18.23 ohms.

The Current in the circuit is

I= V/Req = 12/18.23

I = 0.65 A

The Current in the 8 ohm resistor is I₈ = 0.30 A

The Current in the 4 ohm resistor is I₄ =0.65 A

Their ratio  I₈/I₄ = 0.46

Thus, the ratio of current in the 8-ohm resistors to the current in the 4-ohm resistors is 0.46.

III. The current in 8 ohm is less than the current in 4 ohm resistor.

IV. Current in the 8 ohm resistor is I₈ = 0.30 A

Current in the 3 ohm resistor is I₃ = 0.30 A

Their ratio  I₃/ I₈ = 1

Thus, the ratio of current in the 3-ohm resistors and 8-ohm resistor to the current in the 10-ohm resistors is 1.

V. The current in 3 ohm and 8 ohm resistor is same.
