Given:

Identical charge C

Separation between two charges  m

For finding the electrical force,

According to the coulomb's law

Here, force between two balloons are repulsive because both charges are same.

Where    N  Therefore, the electric force between them is 878.

The weight of the stone is 10N.

To find the weight of the stone, we need to know about the gravitational force on any object due to earth.

When an object is near the earth surface, its weight is mass × gravitational acceleration (g).

So, the weight of the stone= 1kg × 10 m/s²

                            = 10 N

Thus, we can conclude that the weight of the stone 100 m above a gorge is 10N.

We have that for the Question "" it can be said that how long will it take the car to come to a full stop and the car lengths before a stop is

From the question we are told

Your car can brake with a deceleration of 6 m/s2. The car is initially going at 40 m/s.

a) How long will it take the car to come to a full stop?  

b) If the car is 5 meters long, about how many car lengths should be kept between you and the car in front of you (assume the car in front of you comes to a stop immediately).

Generally the equation for the Velocity is mathematically given as

[tex]v=u+at\\\\Therefore\\\\40=0+6t\\\\t=6.667s\\\\[/tex]

b)

s=ut+1/2at^2

Therefore

[tex]S=0+1/2(6)(6.7)^2\\\\S=134.67m[/tex]

Therefore

The car lengths before a stop is

L=134.67m/5

Explanation:

Answer:

-Increase in temperature: increase

-Decrease in temperature: decrease

-Increase in volume: increase

-Decrease in volume: decrease

-Increase in pressure: increase

-Decrease in pressure: decrease

Explanation:

-Increase in temperature:

● Molecules gain kinetic energy and move fast thus increasing distance

-Decrease in temperature:

● Kinetic energy of molecules decrease so they have smaller distance

-Increase in volume:

● Molecules have more space to move around so distance increase

-Decrease in volume:

● Less space, molecules collide with each other because of decreased distance thus increasing pressure

-Increase in pressure

● Molecules collide with each other and the walls of container increasing pressure so molecules move faster and it increases distance

-Decrease in pressure:

● Molecules collide with each other and walls of container less frequently so distance between molecules decrease

Answer:

p>Whether an object will float or sink is dependent on its density, and on the density of the liquid it is placed in. In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level.

Explanation: Just plug the equation into the calculator as is

Answer:

If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. Kinetic energy can be passed from one object to another in the form of a collision....What happen to the kinetic energy of its velocity become double ? The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed is called its kinetic energy. Hence, when velocity is doubled, kinetic energy becomes 4 times.

Explanation:

Answer: It increases by four times

Explanation: If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. Kinetic energy can be passed from one object to another in the form of a collision.

The Oort cloud is the proximate source of observed nearly parabolic, so-called 'new' comets entering the planetary region, and is also the presumed source of the long-period comet flux and the majority of Halley-type comets (HTCs).

The oort cloud is important for understanding the formation of the solar system.

It is believed to be an important source of comets that can provide valuable information about the conditions and processes that were present in the early solar system.

Here,
The Oort Cloud is important for understanding the formation of the solar system because it is believed to be a reservoir of icy bodies that formed early in the solar system's history. These icy bodies, which include comets, are thought to have played a key role in the early evolution of the solar system by delivering water and other volatile materials to the inner solar system, including the early Earth.

By studying the composition and properties of comets from the Oort Cloud, scientists can gain insights into the formation and evolution of the solar system and learn more about the conditions that were present in the early solar system.
