Will we run out of rocket fuel? So no, it is literally impossible to run out of modern rocket fuel, as we basically reuse it (when burned, turned into water vapour, rains down, we collect it and separate it into the two gasses, which can then be burned again. We will only run out of […]

What is the correct order for Organisational planning? There are four phases of a proper organizational plan: strategic, tactical, operational, and contingency. Each phase of planning is a subset of the prior, with strategic planning being the foremost. What is the overall focus of strategic planning? Strategic planning is an organizational management activity that is […]

Where does the sun go when it sets? Answer: The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that’s because Earth spins — toward the east. Where does the moon rise if the Earth rotates counter clockwise? The Earth rotates counter-clockwise on its axis […]

What is a potential failure mode? Definition: Potential failure mode is defined as the manner in which the process could potentially fail to meet the process requirements and/or design intent as decribed in the process function/requirements column. ( What are the three usual causes of failure? The usual causes of material failure are incorrect materials […]

What happens if a plane is too heavy? If the plane is too heavily loaded, then you will be unable to take off. (You might be able to get a meter or two above the ground due to a phenomenon called “ground effect”, but you could not climb any higher.) Is basic weight the same […]

What is the lowest temperature that a substance can reach? Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach. What is 70 […]

At what distance does a long straight wire carry a current? Answer. Magnetic field, We have to find the distance from a long straight wire that is carrying a current of 12 A. Hence, at 0.08 m from a long straight wire carrying a current of 12 A. What basic principle enables all electric generators? […]

Will my pool pop out of the ground if I drain it? Inground pools made of concrete or gunite are susceptible to popping out of the ground if drainage is not done properly. Excessive ground water can cause this type of pool to “float” out of the ground when draining is occuring. Can you fix […]

Is FCC stronger than BCC? FCC and BCC also have many different measurements within the unit cell, as shown in the table below. Additionally, FCC metals tend to be more dense, more stable at high temperatures, and more ductile than BCC metals. This comes from their packing arrangement and slip systems. Why is it called […]

Can gravitons be detected? We attempt to answer Dyson’s question and find it is possible concoct an idealized thought experiment capable of detecting one graviton; however, when anything remotely resembling realistic physics is taken into account, detection becomes impossible, indicating that Dyson’s conjecture is very likely true. Are gravitons affected by gravity? If gravitational waves […]
