A vacuum cleaner emits sound energy and some heat energy. The sound energy is produced by the motor and fan inside the vacuum cleaner, while the heat energy is a byproduct of the motor's operation.
Yes, lasers emit coherent monochromatic light due to the process which light is created. It is created by exciting molecules continuously to one energy level and emitting the energy back to a sort of chain effect as the emitted light is partially used to excite more molecules, therefore due to the specific energy level changes in the excited medium, the light emitted is of one specific wavelength.
The cyclist has gained potential energy as she reaches the summit. This energy is stored due to her position and height in relation to the ground.
In order for heat to transfer by convection, there has to be air or water in order for the molecules to move from place to place. So both these heat transfer techniques require a medium of some sort. In a vacuum, there's no particles at all, so there is no medium present in order for these heat transfers to apply.
When a rocket is taking off, it has kinetic energy due to its motion as it propels itself upwards. Additionally, it has potential energy as it gains height in the Earth's gravitational field.
Potential energy is stored within an object suspended above the ground. This potential energy is due to the force of gravity acting on the object, creating the potential for it to fall and convert that potential energy into kinetic energy.
The atom will emit some sort of electromagnetic radiation. It can range from x-rays to visible light depending on which energy levels are involved
Narwhals create a sort of vacuum and sucks up its food
If by "cleaner" you mean content, sex, violence, that sort of thing. Yes, Futurama is cleaner.
Many hardwood floor vacuums offer three options. The first is vacuum, then heated wet vacuum, and then drying. It sort of functions as both a mop and a vacuum.

Yes, radium is a radioactive element that can emit radiation and is used in some types of nuclear reactions to produce energy. It is not commonly used in nuclear power plants but has been used historically in early experiments to explore nuclear reactions.
