To solve this problem we will apply the momentum conservation theorem, that is, the initial momentum of the bodies must be the same final momentum of the bodies. The value that will be obtained will be a vector value of the final speed of which the magnitude will be found later. Our values are given as,




Using conservation of momentum,


Solving for 

Using the properties of vectors to find the magnitude we have,


Therefore the magnitude of the velocity of the wreckage of the two cars immediately after the collision is 12.4135m/s
Answer:
A) Greater than the attraction between two small objects the same distance apart.
Explanation:
The gravitational force between two objects is:
F = GMm / r²
where G is the gravitational constant,
M is the mass of one object,
m is the mass of the other object,
and r is the distance between the objects.
If the distance is the same, then two large objects will have a larger gravitational force between them than two small objects.
Surface tension and surface energy are two very important concepts discussed in physics. The concepts of surface tension and surface energy are widely used in fields such as fluid mechanics, fluid dynamics, aerodynamics and various other fields. Surface tension is the net intermolecular force on the surface molecules of a liquid. Surface energy is the relevant energy of these bonds. In this article, we are going to discuss what surface tension and surface energy are, their applications, the definitions of surface tension and surface energy, their similarities, and finally the difference between surface tension and surface energy.
When developing a question for a scientific inquiry, the question will ideally D. all of these.
When it comes to a scientific inquiry, it is important that the question identify variables, be measurable, and not just simply ask why. There have to be a couple of variables, you have to be able to measure the results, and to prove them, supported by evidence.
Answer:
The Sun is the energy source for the motion of gas in the atmosphere. Gravity prevents atmospheric gases from flying off into space.
