Answer:
Explanation:
We name M the larger mas, and m the smaller mass, so base on this we write the following conservation of momentum equation for the collision:
We can write this in terms of what we are looking for (the quotient of masses :
We use now the information about Kinetic Energy of the system being reduced in half after the collision:
We can combine this last equation with the previous one to obtain:
where solving for the quotient m/M gives:
Heat pumps work by transferring heat energy between two areas. The most common type, the air-source heat pump, uses a coil of refrigerant to absorb heat from indoor air and transfer it to the air outside for cooling. In cold weather, the heat pump reverses the direction of heat transfer.
You know you can skip those and just submit them, they don’t even check them
Radio waves are a type of electromagnetic (EM) radiation with wavelengths in the electromagnetic spectrum longer than infrared light.
