Answer:
The impulse of the net force on the ball during its collision with the wall is 25N
Explanation:
Step one :
Given data
Mass =5kg
Velocity v1=10m/s
Velocity v2=5m/s
The equation for impulse is given as
P=m(v1-v2)
Where P =impulse
Substituting our values into the equation we have
P=5*(10-5)
P=5*5
P=25N
The impulse 25N
What is impulse?
Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time.
The answer to this question would be electron.
Electron is located on the outer side of the atom and constantly moving in an orbit so its location cannot be accurately determined. The cloud around the center of the atom is drawn to picture the orbit.
Neutron and proton located in the middle of an atom in a part that called nucleus. Nucleus location is kept at the center and it doesn't move.
chemical to thermal to electromagnetic
Explanation:
The best statement that shows the energy transformations that took place is from chemical to thermal to electromagnetic energy.
- In all isolated systems, energy is neither created nor destroyed but transformed from one form to another according to the law of conservation of energy.
- The firewood contains a chemical potential energy at rest. This energy is contained in the carbon chains of organic compounds it houses.
- When combustion takes place, kinetic energy in form of thermal energy is liberated. The bulk is in form of heat.
- This energy dissipates in all direction as a form of radiant electromagnetic energy in the infra-red range.
