The orbital period is 31.62 years when the average distance from the sun is 10AU
|| ✪ Explanation✪ ||
Given:
The average distance of the planet from the sun is r = 10 AU
To find the orbital period.
According to Kepler's third law,
[tex]T^{2}[/tex] ∞ [tex]r^{3}[/tex]
[tex]T^{2} =kr^{3}[/tex]
[tex]T=\frac{3}{2}[/tex]
Here, the constant k is taken to be 1.
Substituting the values, the orbital speed will be
[tex]T=(10)\frac{3}{2}[/tex]
[tex]=31.62~years[/tex]
Final Answer: The orbital period is 31.62 years when the average distance from the sun is 10AU

An airplane travels 280m down the runway before taking off. If it starts from rest, moves with constant acceleration, and becomes airborne in 8.00 s, what is its speed, in m/s, when it takes off?
Answer:
the average speed is ... 280 m / 8.00 s = 35 m/s
the initial speed is zero (rest), so the final speed (take off) is
... ave = (init + fin) / 2 ... 35 = (0 + f) / 2 ... f = 70 m/s

A microwave oven has a power of 1800 W and the potential difference applied from the mains is 230 V. What are its current and resistance?
Answer:
I = 7.826A
R = 29.38 Ω
Explanation:
First, let us find the current of the microwave.
Let us use the below formula for that.
Power = Voltage × Current
Current = Power ÷ Voltage
= 1800w ÷ 230v
= 7.826 A
And now let us find the resistance using the below formula.
Voltage = Current × Resistance
Resistance = Voltage ÷ Current
= 230V ÷ 7.826A
= 29.38 Ω

A quarter rolls off a table with an initial horizontal velocity of 0.24 m/s. If the quarter lands 0.42 seconds later on the ground. How far from the table did it land?
Answer:
0.10 m
Explanation:
Given in the x direction:
v₀ = 0.24 m/s
a = 0 m/s²
t = 0.42 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (0.24 m/s) (0.42 s) + ½ (0 m/s²) (0.42 s)²
Δx ≈ 0.10 m
The distance from the table with the horizontal velocity of 0.24 m/s and time t is 0.42 s is 0.10m.
What is velocity?Velocity is defined as the rate of displacement per unit time. It equals the speed along with the direction. Velocity is the vector quantity as it has both magnitude and direction.
The velocity can be classified as instantaneous velocity and average velocity. Average velocity is obtained by the ratio of total displacement to total time. The unit of velocity is m/s.
From the given,
Initial velocity (u) = 0.24 m/s
time = 0.43 s
acc (a) = 0
distance (s) =?
By using the equation of motion:
s = ut + 1/2 (at²)
= 0.24×0.42 + (0×0.42×0.42)/2
= 0.10 + 0
s = 0.10 m
Thus, the distance traveled from the table is 0.10 m.

Imagine that you are in a space station in the vacuum of outer space, far from any planet. There is no air in space, so there is no friction. There is also very little gravity. You throw a ball out the door of the space station. Use Newton's first law of motion to predict what will happen to the motion of the ball.
Answer:
The ball will continue to move at a constant speed forever until another force stops it.
Explanation:
Newton's first law of motion can be seen as a law of inertia. It explains that an object at rest or in a state of uniform motion will remain in that state unless it is acted upon by an external force.
Following the above, when the ball is thrown into space, the ball will continue to move with the velocity with which it was thrown until it comes in contact with another object that stops it. If this does not happen, it will continue to drift forever at that velocity.
A 30.6 kilogram object is pulled by a horizontal force of 243 newtons causing it to accelerate at 5 meters per second squared. What is the force of friction acting on the
object? Calculate the coefficient of friction of the two surfaces.
Answer:
Ffriction = 90 N
coefficient = 0.3
Explanation:
First, note that the sum of all the forces in the x directions equals the mass multiplied by the acceleration in the x direction.
assuming the direction of the pulling force is positive,
243 N - Ffriction = m * a
m= 30.6 kg
a= 5 m/s/s
Ffriction= 243 - m*a
Ffriction= 243 - (30.6)(5)
Ffriction=90 N
The force of friction is equal to the coefficient of friction multiplied by the normal force on the object. Because the pulling force is completely horizontal, the normal force of the object is equal to its weight, which is m * g, or (30.6 kg)(9.8 m/s/s) = 299.88 N
Ffriction = coefficient * Fnormal
90 = coefficient * 299.88
coefficient = 0.3

Which of the following determine the chemical properties of an element?
A)Its protons
B)Its inner shell electrons
C)The size of its nucleus
D)Its valence electrons
Answer:
D, valence electrons.
Explanation:
Since the number of shells are dependent on the number of valence electrons, which determines the period of the element. Because each shell of an element holds a total of 8 valence electrons, there is a chemical association that is being made between the outer electrons and the atom.
Answer:
The correct answer is D. Its valence electrons.
Explanation:
The valence electrons are those that participate in reactions with other elements. The fewer valence electrons that an element has, the less stable it becomes; an element with a full valence electron shell does not frequently interact with other elements. In this way, the valence electrons determine the chemical properties of an element.

When using the right-hand rule to determine the direction of the magnetic force on a charge, which part of the hand points in the direction of the magnetic field? palm fingers back thumb
When using the right-hand rule to determine the direction of the magnetic force on a charge, the thumb is in the direction of the magnetic field.
What is the right-hand thumb rule?The right-hand thumb rule is the method to recognize that there is only one velocity, which is symbolized by the thumb. There are a lot of field lines, which are symbolized by the fingers.
The force is directed in the direction in which you would press your palm. The force acting on a negative charge is the polar opposite of that acting on a positive charge.
A pure magnetic field will not accelerate a charged particle in a single direction since the force is always perpendicular to the velocity vector, but it will create circular or helical motion
It's worth noting that a magnetic field has no effect on a static electric charge. These two findings are consistent with the rule that magnetic fields are polarized.
Hence using the right-hand rule to determine the direction of the magnetic force on a charge, the thumb is in the direction of the magnetic field.

Explanation:
Please select the word from the list that best fits the definition increases in the number of ______ can lead to warmer climates
The word from the list that best fits the definition increases the number of sunspots that can lead to warmer climates.
What is a sunspot?Sunspots are transitory spots on the Sun's photosphere that appear to be deeper than the surrounding areas.
They are zones of reduced surface heat caused by magnetic field flux concentrations that prevent convection.
Sunspots usually form in pairs with opposite magnetic polarities. This has an impact on the temperature on Earth, as well as radio reaction. The Earth would presumably be colder if sunspots didn't exist.
When sunspots form, they produce an increase in UV radiation that radiates from the sunspots' outer ring as they approach Earth.
This increase in UV radiation has an impact on the chemistry of the outer environment as well as the Earth's energy balance.
The idea that sunspots have an impact on Earth's ecology is still controversial, although it does exist.
Hence the words from the list that best fits the definition increase the number of sunspots that can lead to warmer climates.

What kind of energy could be directly used to solve for the launch velocity?
how much time does it required for an airplane to reach its take off speed of 77 m/s if it starts from rest and its average acceleration is 8.2 m/s^2
Answer:
t = 9.38 seconds
Explanation:
Given that,
Initial speed of the airplane, u = 0 (at rest)
Final speed of the airplane, v = 77 m/s
Acceleration of the airplane, a = 8.2 m/s²
We need to find the time required for the airplane to accelerate. The formula of acceleration is given by :
[tex]a=\dfrac{v-u}{t}\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{77-0}{8.2}\\\\t=9.38\ s[/tex]
So, the time taken by the airplane is 9.38 seconds.
