What is the principle of Kvl? Kirchhoff’s Voltage Law (KVL) states that, for any loop in an electrical circuit, the sum of the electrical voltage across the loop is zero. Kirchhoff’s Voltage Law is based on the principle of the conservation of energy. What is loop current? The Loop Current is a flow of warm […]
How many electrons are ejected?
How many electrons are ejected? Each packet or photon could cause one electron to be ejected, which is like having a moving particle collide with and transfer energy to a stationary particle. Can electrons be ejected? When light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon […]
What temperature does 50/50 antifreeze freeze at?
What temperature does 50/50 antifreeze freeze at? BOILING & FREEZING POINTS Pure water, as you may know, has a boiling point of 212°F (100°C) and a freezing point of 32°F (0°C). However, when you create a 50/50 mixture using water and ethylene glycol, the boiling point rises to 223°F (106°C) and the freezing point lowers […]
How is fan efficiency calculated?
How is fan efficiency calculated? Fan efficiency is defined as the air power divided by the fan input power. Both Static and Total Efficiency can be calculated from fan performance data as follows: wg BHP = Fan power input, hp Static and total fan efficiency (Figure 1) can be plotted along with the fan curve. […]
What type of solution has a small amount of solute?
What type of solution has a small amount of solute? dilute solution What is an example of saturated solution? Examples of Saturated Solutions A soda is a saturated solution of carbon dioxide in water. Adding chocolate powder to milk so that it stops dissolving forms a saturated solution. Salt can be added to melted butter […]

Can humans live on the sun?
Does sleep increase brain activity?
Does sleep increase brain activity? It is believed that dreaming occurs for at least 2 hours each night during REM sleep and that this activity plays an important role in the processing of information and the creation of memory. During this stage of sleep, heart rate and blood pressure increase and the activity of the […]

Skeletal Muscles in the Human Body coracobrachialis. biceps brachii. brachialis anticus. triceps brachii. anconeus. pronator teres. flexor carpi radialis. palmaris longus. What are the important functions of skeletal muscle? Skeletal muscles enable humans to move and perform daily activities. They play an essential role in respiratory mechanics and […]
What are the factors that affect the strength of magnetic field?
What are the factors that affect the strength of magnetic field? Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core. Can magnets damage your body? […]
