What are the advantages of a dynamic microphone? Key advantages to a dynamic microphone: Rugged and able to handle high sound pressure levels, like those delivered by a kick drum. Provide good sound quality in all areas of microphone performance. They do not require a power source to run. They are relatively cheap. What do […]
What are the first signs of heat stress?
What are the first signs of heat stress? WHAT TO LOOK FOR Heavy sweating. Cold, pale, and clammy skin. Fast, weak pulse. Nausea or vomiting. Muscle cramps. Tiredness or weakness. Dizziness. Headache. What is the difference between heat stress and heat stroke? Both heat exhaustion and heat stroke are serious conditions. Heat exhaustion begins with […]
What is the relationship between resistance and current?
What is the relationship between resistance and current? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is the property of […]
What is the purpose of thin layer chromatography?
What is the purpose of thin layer chromatography? TLC is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography can be used to monitor the progress of a reaction, identify compounds present in a given mixture, and determine the purity of a substance. What are the two major uses of thin layer chromatography? The […]
How do you log physical activity?
How do you log physical activity? How to Use a Weekly Physical Activity Log Record your activity goals. Record the type of activity you do and how long you’re active. Record notes on how the activity felt, what you noticed and things you learned while doing the activity. Record any changes you’d like to make […]

It absorbs violet-blue wavelength. Energy Absorption It absorbs energy from wavelengths of blue-violet and orange-red light. It absorbs energy from wavelengths of green light. What […]
What are two examples of biogeochemical cycles?
What are two examples of biogeochemical cycles? Ecological systems (ecosystems) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. Is photosynthesis a biogeochemical cycle? This type of cycle of atoms […]
Is needed to start a chemical reaction?
Is needed to start a chemical reaction? Chemical reactions won’t begin until the reactants have enough energy. The energy is used to break the chemical bonds of the reactants. Then the atoms form the new bonds of the products. Activation Energy is the minimum amount of energy needed to start a chemical reaction. What 3 […]

Share on Pinterest Drinking water regularly may help to treat a UTI. Urinate when the need arises. Drink cranberry juice. Use probiotics. Get enough vitamin C. Wipe from front […]
What happens to Wavefunctions as n increases?
What happens to Wavefunctions as n increases? Note that as n increased, the energy of the wavefunction increases (Equation 3.5. 12) and both the number of nodes and antinodes increase and the frequency of oscillation of the wavefunction increases. When the particle strikes the wall of the well it bounces off completely true or false? […]
