Doesn't putting a lightning rod on top of church show a lack of faith?
I agree with Scott. The best type of dog is a noisy dog as they will draw attention to the house and the people that are attempting to break in. If you do not want a dog, still put up the signs, maybe a leash and an anchor in the ground. If you can tape the sounds of a large dog barking and play that when someone comes to the door. If you know someone handy who can wire it to play when the door bell sounds even better.
Electromagnetism is the physics of the electromagnetic field: a field which exerts a force on particles that possess the property of electric charge, and is in turn affected by the presence and motion of those particles. In thermal physics, heat transfer is the passage of thermal energy from a hot to a colder body. When a physical body, e.g. an object or fluid, is at a different temperature than its surroundings or another body, transfer of thermal energy, also known as heat transfer, or heat exchange, occurs in such a way that the body and the surroundings reach thermal equilibrium. Kinetic energy is the enrgy of motion Examples of kinetic energy are roller coasters, spacecraft, A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy Anything moving is using kinetic enrgy Potential energy is energy that is stored in an object. If you stretch a rubber band, you will give it potential energy. As the rubber band is released, potential energy is changed to motion.
