When you run up the stairs you do more work than when you walk up slowly? In other words, it is a measurement of how fast you are using energy. Whether you run up a flight of stairs in 5 seconds or take a slow walk up the same flight in 40 seconds, you are […]
Why is my high side pressure low?
Why is my high side pressure low? Higher Low Side and Lower High Side Pressures Too much refrigerant is flowing into the evaporator. The TXV is stuck open or the thermal bulb is not sensing the temperature correctly. The orifice tube is too large of an opening or the o-ring sealing the outside of the […]
What materials are poor insulators?
What materials are poor insulators? Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood. Why does aluminum heat up faster than steel? Aluminum has much more […]

Are humans digital or analog?
Are humans digital or analog? The brain is neither analog nor digital, but works using a signal processing paradigm that has some properties in common with both. Unlike a digital computer, the brain does not use binary logic or binary addressable memory, and it does not perform binary arithmetic. Why is digital cheaper? Digital is […]
What are two ways in which neurons are classified?
What are two ways in which neurons are classified? Neurons can be classified by the direction of the action potential or route by which information travels. Afferent neurons convey information from tissues and organs to the brain and efferent signals transmit information from the brain to effector cells in the body. What are the structural […]
What are the 3 functions of the cerebellum?
What are the 3 functions of the cerebellum? The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. What part of the brain is […]
Is Steam matter Yes or no?
Is Steam matter Yes or no? Water illustrates the three states of matter: solid (ice), gas (steam), and liquid (water). Why is steam so powerful? The water is still nearby, but it’s now in a gaseous form called steam. This form of water is also called water vapor, and it’s very powerful stuff. This is […]
How are the macroscopic properties classified?
How are the macroscopic properties classified? The physical properties of matter are classified as macroscopic and microscopic properties. “Properties of matter in bulk are called macroscopic properties. While microscopic properties are the properties of constituents of the bulk matter, properties of atoms and molecules”. Is temperature a microscopic or macroscopic? Temperature is a macroscopic parameter […]
What is the minimum possible mass for a star in solar masses?
What is the minimum possible mass for a star in solar masses? According to theoretical calculations, the smallest mass that a true star can have is about 1/12 that of the Sun. By a “true” star, astronomers mean one that becomes hot enough to fuse protons to form helium (as discussed in The Sun: A […]
