the chart below compares the characteristics of four objects discovered in the solar system. which of these objects is most like
olga_2 [115]

Answer:

I would go with B

Explanation:

first of all,planets don´t exist in Kuiper belt because that is where dwarfs go

second,a planet is not a moon of another object,there is no such thing as that

third,planets do have enough gravity to keep other objects far away from its orbit.

fourth,a planet does orbit around the sun

fifth,planets do have a long orbit

sixth,a planet is also almost in a circular shape

B was the most likely to be a planet because one of the characteristics were wrong,unlike the others,I also hope this helps and hope that its the right answer,I'm actually not too sure,sorry if I got it wrong.

A particle (charge = 40 μC) moves directly toward a second particle (charge = 80 μC) which is held in a fixed position. At an in
lisov135 [29]

Answer:

The distance separating the two particles when the moving particle is momentarily stopped is 0.947 m

Explanation:

Given that,

First charge = 40 μC

Second charge = 80 μC

Distance between the two particles = 2.0 m

Kinetic energy = 16 J

We need to calculate the distance separating the two particles when the moving particle is momentarily stopped

Using conservation of energy

K.E+\dfrac{kq_{1}q_{2}}{d}=\dfrac{kq_{1}q_{2}}{x}+K.E

Put the value into the formula

16+\dfrac{9\times10^{9}\times40\times10^{-6}\times80\times10^{-6}}{2}=\dfrac{9\times10^{9}\times40\times10^{-6}\times80\times10^{-6}}{x}+0

16+14.4=\dfrac{28.8}{x}

30.4x=28.8

x=\dfrac{28.8}{30.4}

x=0.947\ m

Hence, The distance separating the two particles when the moving particle is momentarily stopped is 0.947 m

The force that accelerates a rocket in outer space is exerted on the rocket by the?
Nana76 [90]

Gases at pressure are released by rockets as they travel towards space. According to Newton's third law, the combustion chamber's exhaust gases push the rocket with an accelerating force known as the thrust.

<h3>Explain exactly Newton's Third Law:</h3>

According to Newton's third law, if an object A pulls on an object B, then object B must exert an equal-sized and opposite-direction force on the first thing directed in the opposite direction. This law illustrates a symmetry in nature whereby forces always occur in pairs and whereby no body can exert a force without also being subjected to one.

<h3>What are Newton's 3rd law examples?</h3>

Action and response are always equal but always move in the opposite direction, according to Newton's third law of motion. A human walking on the ground, a hammer driving a nail, a magnet attracting a paper clip, and a horse pulling a cart are all examples of Newton's third rule of motion.

Two trains, each having a speed of 33 km/h, are headed at each other on the same straight track. A bird that can fly 60 km/h fli
Alex Ar [27]

Answer:

66 km

Explanation:

Given that:

The speed of the two trains = 33 km/h

The speed of the bird = 60 km/h

The distance apart between the two trains =  60 km

From the given information, we are being told that the two trains are going at the same speed. Therefore, they will definitely collide at 30 km

We know that:

speed  of the train = distance traveled × time

Making the time t the subject of the formula:

time = speed of the train / distance traveled

time = 30 km / 33 km/h

time = 0.909 / hr

Thus, the bird flying at a given speed of 60 km/h in a time of 0.909 / hr will cover a total distance of :

distance (d) = speed of the bird/ time

distance (d) = \dfrac{60 \ km/hr}{0.909 \ /hr}

distance (d) = 66 km
