Extension of the elbow? im not sure
A. 4% you divide 2000 to 500 and you get 4 which is your answer
Answer:
False. The net force is Zero
Explanation:
To answer this question we propose the solution of the problem.
We have a toy where balls come in and out after crashes between them, this toy forms our system, so all the balls are parts of the system, when the balls collide with each other according to Newton's third law force and action and reaction, so it has the same magnitude, but opposite direction, this is each is applied to some of the objects.
In conclusion of the previous one for the system the net force is Zero, all are internal. Therefore, the only thing that happens is a redistribution of speeds according to the conservation of the moment.
Let's review the answer.
False. The net force is Zero
Answer:
Energy: Kinetic, Sound, Thermal, gravitational, electric, light and nuclear
Explanation:
This exercise asks to clarify a little some important concepts
* Energy. It is the capable one that has the bodies to carry out a job.
* Kinetic energy. It is the energy due to the movement of objects
* sound energy. It is the energy due to the vibration of the atoms or molecules of the materials, it can be solid, liquid or gaseous
* Thermal energy. It is the energy due to movement of the particles
* Gravitational Energy. It is a configuration energy due to the height of the bodies with respect to a reference point
* Electric power. It is due to the movement of electric charges
* light energy. It is the energy that light carries due to the electric and magnetic fields that form it, it occurs throughout the electromagnetic spectrum
* Nuclear energy. It is the energy stored in the nucleus by the configuration and movement of protons and neutrons.
Answer:
1. Thermal Energy is the internal energy that is produced from the temperature of a heated substance/object.
2. From the potato to the soup and from the soup to the surrounding room
Explanation:
1. When an object or substance is heated it causes a rise in temperature which makes the atoms and molecules within the object move/vibrate faster and collide with each other. This kinetic energy energy comes from the temperature of the object being heated and is the thermal energy.
2. The atoms present in a hot object have higher kinetic energy when compared to a colder object and usually flow towards the colder object. This is why it is possible for the hot potato whose temperature is higher than the bowl of soup to flow towards the soup and from the soup to the surrounding room.
