Is gravity fully understood? We don’t really know. We can define what it is as a field of influence, because we know how it operates in the universe. And some scientists think that it is made up of particles called gravitons which travel at the speed of light. Did Einstein believe in gravity? Einstein argued […]
How do you find the concentration of a standard curve?
How do you find the concentration of a standard curve? To calculate the sample concentration based on the standard curve, first you find the concentration for each sample absorbance on the standard curve; then you multiply the concentration by the dilution factor for each sample. Why do we need a standard curve to determine a […]
What triggers side airbags?
What triggers side airbags? Rollover deployment of side airbags Side curtain airbags can be designed to deploy in a rollover crash. Sensors that measure a vehicle’s sideways movement and tilting can detect if a rollover is about to occur, triggering deployment. How many seconds does it take for an airbag to inflate? 0.03 SECOND Why […]
How is Vickers hardness test calculated?
How is Vickers hardness test calculated? The Vickers number (HV) is calculated using the following formula: HV = 1.854(F/D2), with F being the applied load (measured in kilograms-force) and D2 the area of the indentation (measured in square millimetres). What is the load that the Vickers hardness test can carry? 1-120 kg What is the […]
What is E7018 electrode?
What is E7018 electrode? E7018 electrodes contain a thick flux with high powder content and are one of the easiest electrodes to use. These electrodes produce a smooth, quiet arc with minimal spatter and medium arc penetration. Many welders use E7018 electrodes to weld thick metals such as structural steel. What does 7018 stand for? […]
What is evaporator in air conditioner?
What is evaporator in air conditioner? An air conditioner’s evaporator coil, also called the evaporator core, is the part of the system where the refrigerant absorbs heat. That is, it’s where the cold air comes from. As the air conditioner runs, the compressor pulls cold, low-pressure liquid refrigerant through the tubing in the evaporator coil. […]
How can team decision making be improved?
How can team decision making be improved? 6 Ways Managers Can Improve Team Creativity and Decision Making Be mindful. What is the desired outcome? Don’t act bureaucratically. Avoid “My way or the highway.” Don’t drag decision making out too long. Avoid “analysis paralysis.” Trust yourself. Trust your team. Add resources. Remove obstacles. Read the Group. […]
What is required to decrypt an encrypted message?
What is required to decrypt an encrypted message? To decrypt a message the option –decrypt is used. You need the private key to which the message was encrypted. Similar to the encryption process, the document to decrypt is input, and the decrypted result is output. blake% gpg –output doc –decrypt doc. How do you decrypt […]
What is the fastest plane in the world 2020?
What is the fastest plane in the world 2020? The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this […]
What is stress in polymer?
What is stress in polymer? Polymers exhibit a wide range of stress-strain behaviors as shown in the figure below. For polymer materials, this peak stress is identified as the yield stress. As the material is pulled further, fracture occurs. The stress value when fracture occurs is defined as the tensile strength for polymer materials. What […]
