Planets in the solar system revolve around the Sun in an orbital path and can vary from rocky and terrestrial objects to gaseous and liquid object. Which set of characteristics is unique to the outer planets
Answer:
Gaseous; liquid.
Explanation:
A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.
Some examples of the planet are Mars, Venus, Earth, Mercury, Neptune, Jupiter, Saturn, Uranus, Pluto, etc.
Basically, the planets are divided into two (2) main categories and these includes;
I. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.
II. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.
These outer planets are made mostly of gases (hydrogen and helium) causing them to be less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.
In conclusion, Planets in the solar system can vary from rocky and terrestrial objects to gaseous and liquid object.
However, the set of characteristics which is unique to the outer planets are gaseous and liquid.

a bag of sugar is found to have the same weight on planet earth as an identical bag of dry sawdust on planet Jupiter explain why the masses of the two bags must be different
Answer:
Because Jupiter is a much larger planet than Earth, its gravitational pull is 240% stronger than that of earth. This is why sawdust, which is lighter than its equivalent measure of sugar would weigh more on Jupiter.
Explanation:
Let's assume that a type of bag can contain 50 kilograms of sugar. If that same bag was filled up with sawdust instead, it would weigh far less than 50Kg.
If that bag of sawdust, on earth weighed 35Kg for instance, on Jupiter, the new weight would be:
35Kg x 2.4 = 84Kg
Put differently, Jupiter simply has a stronger gravitational pull than earth. This extra pull is attributed to its size.

A 3 kg book is at rest on the table. What is the magnitude of the normal force that the table is exerting on the book?
Answer:
30 N
Explanation:
The normal force is the component of a contact force that is perpendicular to the surface that an object contacts. This normal force prevents the surfaces from penetrating each other.
Let us assume that the acceleration due to gravity (g) is 10 m/s². Hence the weight of the book (W) is:
W = mass of book * acceleration due to gravity = 3 kg * 10 m/s² = 30 N
The normal force ([tex]F_n[/tex]) is gotten using:
Summation of vertical force = m[tex]a_y[/tex]
[tex]F_y=ma_y\\\\F_n-mg=0\\\\f_n=mg=3kg(10m/s^2)=30\ N[/tex]

The resultant force is indeed the single force and corresponding tension derived by vector addition when combining any system of torques acting on a solid body.
Its associated torque is generated mostly by the time of filing the compliance.The Pythagorean theorem is being used to determine the resulting force whenever one force acts perpendicularly to another. Calculating the resultant force which not includes force: [tex]\to 10-8= 2\ N[/tex]Therefore, the final answer is "Option b".

Nathan is walking to the store and sees a snake slithering across the sidewalk. He jumps over it with an initial vertical velocity of 10 ft/s. How long does it take for Nathan to land back on the ground
Answer:
[tex]0.62\:\mathrm{s}[/tex]
Explanation:
Since the universal SI unit for velocity is meters/second, let's convert ft/s to m/s:
[tex]10\:\mathrm{ft/s}=3.048\:\mathrm{m/s}[/tex]
We can use the following kinematics equation to solve this question:
[tex]v_f=v_i+at[/tex]
What we know:
The initial velocity, [tex]v_i[/tex], is [tex]3.048\:\mathrm{m/s}[/tex] (physics concept) The final velocity must be equal in magnitude but opposite in direction to the initial velocity ([tex]v_f=-3.048\:\mathrm{m/s}[/tex]) Acceleration, [tex]a[/tex], is acceleration due to gravity at about [tex]9.8\:\mathrm{m/s}[/tex]Solving for [tex]t[/tex]:
[tex]-3.048=3.048+(-9.8t),\\-6.096=-9.8t,\\t=\frac{-6.096}{-9.8}\approx \boxed{0.62\:\mathrm{s}}[/tex]

Sobre un barco, que se mueve en forma rectilínea, y con velocidad constante de 30 [km/h], se mueve un perro en el mismo sentido del barco a una velocidad de 10 [km/h]. Si alguien observa sentado desde la playa, ¿a qué velocidad verá correr al perro sobre la cubierta del barco?
Answer:
El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.
Explanation:
Para determinar la velocidad del perro con respecto al observador sentado desde la playa a través del concepto de velocidad relativa, descrito en la siguiente fórmula:
[tex]v_{P/B} = v_{P} - v_{B}[/tex] (1)
Donde:
[tex]v_{P/B}[/tex] - Velocidad del perro relativo al barco, en kilómetros por hora.
[tex]v_{P}[/tex] - Velocidad del perro con respecto al observador, en kilómetros por hora.
[tex]v_{B}[/tex] - Velocidad del barco con respecto al observador, en kilómetros por hora.
Si sabemos que [tex]v_{B} = 30\,\frac{km}{h}[/tex] y [tex]v_{P/B} = 10\,\frac{km}{h}[/tex], entonces la velocidad del perro con respecto al observador es:
[tex]v_{P} = v_{B} + v_{P/B}[/tex]
[tex]v_{P} = 30\,\frac{km}{h} + 10\,\frac{km}{h}[/tex]
[tex]v_{P} = 40\,\frac{km}{h}[/tex]
El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.

What wave phenomena best describes the reason for the dark and light bands that
appear on the optical screen during the double slit experiment?
Answer:
Interference
Explanation:
Interference is the phenomenon in which two waves superimpose to form a wave with smaller, larger or same amplitude.
There are two types of interference namely, constructive interference and destructive interference.
Constructive interference occurs when the waves are in phase and destructive interference occurs when the waves are out of phase.
In a double slit experiment, the two slits acts as sources of light and thus the waves combine to produce interference patterns. When the waves are in phase, that is the angle between them is 0°, they form a constructive interference pattern which gives rise to a light band. When the waves are out of phase, that is the angle between them is 180°, they form a destructive interference pattern which gives rise to a dark band.
Note also that diffraction patterns are also observed for wide slits but can be neglected for smaller slits.

You have just learned that the planet core of Mars is no longer radiating heat like the core of Earth. With this information what would you communicate to building designers as the lead geologist in regards to suitable building locations on the surface of Mars? Remember your informing builders about locations that would best avoid natural disasters like marsquakes and volcanoes? What evidence or theories do you have to support your statements?
Answer:
Explanation:
That is a fun question!
Without a hot radiating core like Earth, Mars will have very different geological and seismic events. The Mars core will be relatively cold and there will not be any molten magma. So Mars will not have earthquakes or volcano activities. Both only occur when there is magma flowing or tectonic plate motion and they will not occur with a cold core.
If you were capable of converting mass to energy with 100%, efficiency, how much mass would you need to produce 3.5x10^12 Joules of energy?
Answer:
a) 3.9 x 10⁻⁵ kg
Explanation:
The amount of mass required to produce the energy can be given by Einstein's formula:
[tex]E = mc^2\\\\m = \frac{E}{c^2}[/tex]
where,
m = mass required = ?
E = Energy produced = 3.5 x 10¹² J
c = speed of light = 3 x 10⁸ m/s
Therefore,
[tex]m = \frac{3.5\ x\ 10^{12}\ J}{(3\ x\ 10^8\ m/s)^2} \\\\m = 3.9\ x\ 10^{-5}\ kg[/tex]
Hence, the correct option is:
a) 3.9 x 10⁻⁵ kg

A virtual image is produced by a convex mirror that is 1.60 cm from the mirror. If the magnification is 0.20, how far from the mirror is the object?
The distance of the object from the mirror Is = –8 cm
Calculation of the object distance of a mirrorThe image distance from the mirror = –1.60cm
The magnification of the image = 0.20
The distance of the object from the mirror can be calculated using the formula below:
magnification= – image distance/ object distance
Substitute the available values into the equation above,
0.20 = – 1.60/ X
Make X the subject of formula,
X = – 1.60/0.20
X = – 8cm
The negative sign indicates that the image is virtual which is formed behind the mirror.
Therefore, the distance of the object from the mirror Is = –8 cm.
