Why is pressure not proportional to volume if the temperature changes? Remember that the force of the collisions do not change unless the temperature changes. If the temperature of a gas stays the same, the pressure of the gas increases as the volume of its container decreases. What happens to volume if temperature increases? The […]
What is difference between humidity and relative humidity?
What is difference between humidity and relative humidity? Humidity is the amount of moisture or water present in the air in the form of water vapors. It is measured in grams of water in a letter of air (mass/volume). Relative humidity is the percentage of the moisture against the highest possible level of moisture in […]
What causes acceleration problems in a car?
What causes acceleration problems in a car? What Causes Acceleration Problems? Hiccups in air and fuel delivery and sensor issues are the main causes of poor acceleration. However, mechanical issues can also be the cause of low power. What makes a car accelerate faster? Basically, the faster the crankshaft spins with the same amount of […]
Are atoms mass?
Can a stick be used as a machine?
Why do we need to avoid resonance?
Why do we need to avoid resonance? The natural frequency of a system is dependent upon two main factors; stiffness, and mass. If the natural frequency is above or significantly far away from any expected vibration frequencies the resonance will likely no be excited. This theory forms the basis for any structural redesigns implemented to […]
How is friction charged by the body?
How is friction charged by the body? When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be ‘rubbed off’ one material and on to the other. The material that gains electrons becomes negatively charged. How is friction charge produced? When a conductor or material […]
Is light required for oxygen production?
Is light required for oxygen production? Answer 1: By using the energy of sunlight, plants can convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. As photosynthesis requires sunlight, this process only happens during the day. Oxygen is required to do this. What is the rate of oxygen production when […]
How much electricity does the average Australian household use?
How much electricity does the average Australian household use? An average Australian house consumes electricity amounting to 18 KiloWatt(KW) per day or 6570 KW per hour. What is the average home electric consumption? In 2019, the average annual electricity consumption for a U.S. residential utility customer was 10,649 kilowatthours (kWh), an average of about 877 […]
What is the advantage of CCD scanner?
What is the advantage of CCD scanner? In general, CIS allows the construction of smaller sizes as well as lower power consumption, while CCD technology allows a higher depth of field, higher speed and signal noise ratio and better colour accuracy – so higher quality and productivity. What cameras have CCD sensors? CCD Still Has […]
