Answered by Alan Jensen, Registered Pharmacist That is a very interesting question. Sound travels at different speeds in different mediums. In a gaseous medium sound travels faster in lighter gases, and the faster the sound travels, the greater the frequency or higher the pitch of the sound. Since helium is about seven times lighter than…
Question Answered by Alana Jensen, Environmental Educator, INL ESER Program http://www.idahoeser.com You may say the answer is because gravity is pulling the air to the Earth and that is true. Gravity is the reason for the existence of an atmosphere on Earth. Another reason, however, is that the vacuum of space does not exert any…
Question answered by Bryan Bybee, Biologist, INL ESER Program The simple answer is that badgers do not hibernate. Hibernation is a seasonal behavior pattern characterized by long periods of reduced body temperature, inactivity, lowered heart and breathing rates, and suppressed metabolism. Body temperatures may be reduced to nearly that of the surroundings. By this definition,…
Answered by Dr. Steve Shropshire, Physics Professor, Idaho State University If conditions are right sound can travel farther and clearer when it is cold. Sound travels faster in warmer air due to the greater average speed of gas molecules with higher temperature. There is also a very slight increase in sound speed with increasing humidity…
Answered by Tamara Cox, RN, Eastern Idaho Public Health Human skin contains different kinds of sensory receptors (cells) that can identify several distinct types of sensations, such as tapping, vibration, pressure, pain, heat, and cold. Each receptor is triggered by a specific stimulus. Thermoreceptors detect temperature changes and send electrical pulses through sensory nerves to…
Answered by Dr. Brian Tonks, Astronomy Professor, BYU-Idaho On 21 August, 2017, Southeastern Idaho and many other places in the United States are in for a rare treat. We will experience a total Solar eclipse. In Rexburg, the total phase of the Solar eclipse will begin at about 11:33:14 a.m. and last for 2 minutes,…
Answered by Travis Wyatt, National Weather Service, Pocatello Office All lightning comes from thunderstorms. When a thunderstorm develops, electrical charges (either positive or negative) within the cloud separate. This creates two different electric fields between the top of the cloud and the base of the cloud. When these electric fields build up enough, there is…
