Are emotions metaphysical? Emotions are, on one level, chemical reactions – just as on another level, our emotional reactions are very much influenced by our mental attitudes. But emotions are also energy that exists in a very real way on the etheric plane in the emotional body. How do you know if your spiritually connected […]

What are the properties of tensile strength? Properties that are directly measured via a tensile test are ultimate tensile strength, breaking strength, maximum elongation and reduction in area. From these measurements the following properties can also be determined: Young’s modulus, Poisson’s ratio, yield strength, and strain-hardening characteristics. What is meant by impact strength? Impact strength […]

How can you prove that sound is produced by vibration? Take a rubber string stretch it tightly between two supports. Pluck the string, the string begins to vibrate. Then we will be able to hear some sound, stop the movement of the string. Even the sound also stops. Why do I feel small vibrations in […]

What are the examples of constant velocity? Answer to Essential Question 2.3: Some examples of constant velocity (or at least almost- constant velocity) motion include (among many others): • A car traveling at constant speed without changing direction. A hockey puck sliding across ice. A space probe that is drifting through interstellar space. Why velocity […]

Can I leave my lava lamp on all night? Some brands of lava lamps require up to six hours for the lava-like blobs to form and flow properly. Even with the long warm-up time, there is a limit to how long the lamp should be operated continuously to keep it functioning as designed. Do not […]

Is sleet or ice worse? 1. Freezing rain and sleet are a winter storm’s silent hazards. Ice in the form of freezing rain and sleet is just as big of a threat as snow, and often result in a winter weather advisory being issued for the affected region. Ice is arguably more dangerous than the […]

What is the angle of rotation of a circle? In mathematics, the angle of rotation is a measurement of the amount, of namely angle, that a figure is rotated about a fixed point, often the center of a circle. If a cart moves around the wheel once, the angle of rotation is 360°. What is […]

What are the disadvantages of a solar oven? Disadvantages The solar cooker cannot be used at night and during cloudy weather. It takes more time to cook food. The direction of the solar cooker is to be changed continuously towards the direction of the Sun. Solar energy is not available uniformly all the time and […]

How do you increase the force of a wire? If the current-carrying wire is placed in a magnetic field (whose lines of force are at right angles to the wire) then it will experience a force at right angles to both the current direction and the magnetic field lines. The force increases if the strength […]
