Answer:
The two neighboring planets with the greatest distance between them is Neptune and Uranus. This happens when they are at the opposite sides of the Sun at approximately. They are 4500 million miles away from each other.
If by adjacent you mean next to each other, in terms of the order of planets in our Solar System, then the closest would be Earth and Venus; which are separated by about 38,000,000 kilometres when in opposition.
I am not sure about the general patterns..
Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days.
A year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days). It is obvious because it is also the farthest with the longest orbit.
Outer planets are less dense than the inner planets because they posses a big volume but contains not much mass. Try to imagine 2 rocks, one is big, but is hollow or have a lot of holes; and the other is small, but solid with no holes.

Below image, please give me the answer quick.
Answer:
Option A. ⅓V
Explanation:
We'll begin by calculating the total resistance in the circuit. This is illustrated below:
R1 = 1Ω
R2 = 2Ω
R3 = 3Ω
RT =..?
Since all three resistor are in series connections, the total resistance can obtain as follow:
RT = R1 + R2 + R3
RT = 1 + 2 + 3
RT = 6Ω
Next we shall determine the current flowing through the circuit.
Voltage (V) = 2V
Resistor (R) = 6Ω
Current (I) =..?
V = IR
2 = I x 6
Divide both side by 6
I = 2/6
I = ⅓A
Finally, we can obtain the voltage across the 1Ω resistor as follow:
Resistor (R) = 1Ω
Current (I) = ⅓A
Voltage (V) =?
V = IR
V = ⅓ × 1
V = ⅓V
Therefore, the potential difference across the 1Ω resistor is ⅓V

C)the speed in the interval from P1 to P2 is twice the speed in the interval from P6 to P1
D)the speed in the interval from P1 to P2 is less than the speed in the interval from P3 to P4
Answer:
The right answer is area =Area C
Explanation:
We can solve the problem by using kepler's law of planetry motion.
Kepler discovered that area B = area C because of its similar distance of orbit from the sun.
What Kepler discovered?A certain planet sweeps out an area B from the point P3 to P4 in a time t while on the other hand, for the same interval of time t, the planet sweeps out an area C from point P4 to P5, that is equal to the previous area according to second Kepler's law.
So we can conclude that Kepler discovered that area B = area C because of its similar distance of orbit from the sun.

what is the resistance of a toaster that uses 2A when connected to a 120V power source?
Answer:
60 ohms
Explanation:
From Ohm's Law:
V = IR
Where V = 120volts
I = 2A
R = ?
Note that R,V and I represents resistance, voltage and current respectively.
Substituting the above values into the formula.
V = IR
120v = 2×R
120= 2R
Making R the subject
R =120/2
R = 60 ohms
Hence the resistance of the toaster will be 60 ohms.

When a neutral atom looses an electron to another neutral atom, two charged atoms are created.
Explanation:
On the off chance that one of the two unbiased particle looses an electron, it turns out to be emphatically (charge: +1), in light of the fact that the electron conveys a charge of - 1. Thus, the other atom which acknowledges the electron turns out to be adversely charged (charge: - 1). And in the end, we will have two charged atoms.

Monochromatic light is incident on two slits separated by 0,2 mm. An interference pattern is observed on a screen 3,7 m away. The distance between the 3rd dark fringe and the central antinode is 0,048 What is the wavelength of the light? Write your answer in sicentific notation or in decimal form
Answer:
λ = 864 nm
Explanation:
To find the wavelength of the light you use the following formula, which determines the position of the m-th fringe in an interference pattern:
[tex]y_m=\frac{m\lambda D}{d}[/tex] (1)
ym: position of a bright fringe
D: distance from the slits to the screen = 3,7 m
d: distance between slits = 0,2mm = 0,2 *10^-3 m
m: order of the fringe
λ: wavelength of the light
You have the distance from the central peak to the third fringe (0,048m). Then, you can use the equation (1) with m=3 and solve for the wavelength:
[tex]y_3=\frac{3\lambda D}{d}\\\\\lambda=\frac{dy_3}{3D}=\frac{(0,2*10^{-3}m)(0,048m)}{3(3,7m)}=8,64*10^{-7}m\\\\\lambda=864*10^{-9}m=864nm[/tex]
henc, the wavelength of the light is 864nm

What happens to a falling object when the force of air resistance equals the force of gravity?
A)It shows increasing acceleration.
B)It begins to slow down.
C)It reaches terminal velocity.
D) It shows projectile motion.
Answer:
Its C.
Explanation:
When the two forces of gravity and force resistance become the same, the object no longer speeds up , and it doesn't slow down either. This is called terminal velocity .
So ,C is the correct answer .
Hope it works out !!
When the force of air resistance equals the force of gravity, the falling object reaches terminal velocity. Hence, option (C) is correct.
What is terminal velocity?The maximum velocity attained by an object as it falls through a fluid is known as terminal velocity. It occurs when the sum of the drag and buoyancy forces acting on the object equals the downward force of gravity. Because the object's net force is zero, it has no acceleration.
An object is moving at its terminal velocity in fluid dynamics if its speed is constant due to the restraining force exerted by the fluid through which it is moving.
As an object's speed increases, so does the drag force acting on it, which is also affected by the substance it is passing through. The drag or force of resistance will equal the gravitational pull on the object at some speed.

Which sentences describe the cyclone device?
A cyclone device accumulates fine particulates from the air by making a dirty air stream flow in a spiral path inside a
cylindrical chamber. It consists of several long and narrow fabric filter bags suspended upside-down in a large
enclosure. When dirty alr enters the chamber, the larger particulates strike the chamber wall and fall into a conical dust
hopper at the bottom. Fans blow dirt-filled air upward from the bottom of the enclosure, trapping dirt particles inside the
filter bags and releasing clean air from the top. The top of the chamber has an outlet that lets out cleaned air.
Answer: Option A
Explanation:
A cyclone device is an instrument which measures the cyclone. In this case the device collects the particulates mixed in air which makes the air dirty.
It revolves inside the cylindrical chamber in a forming a spiral path. This is what a cyclone is.
In real, the cyclone is also the same but is so huge that it carries away the things coming in its path. These things can be homes, trees and other materials.
This is very destructive and cause loss of life and loss of assets.
