What is needed for the tool to give mechanical advantage? Work is the product of distance and force, so by increasing the distance via a tool one can decrease the force required. The ratio between the force exerted by the tool and the force applied to the tool defines the mechanical advantage. How do you […]

Why is Brainly so bad?
Why is Brainly so bad? This is a horrible website that is used almost exclusively for cheating. Even though their so-called ‘code of honor’ prohibits students from answering or copying tests questions, test cheats make up a substantial chunk of Brainly. As in, it’s what students pretty much ONLY use it for. Is Brainly considered […]
Who discovered cavitation?
Who discovered cavitation? However, actual cavitation was first discovered and investigated by Barnaby and Parsons in 1893 when they found that the formation of vapour bubbles on the propeller blades was responsible for the sea-trial failure in 1885 of a British high-speed warship HMS Daring. How does cavitation appear? Cavitation inception occurs when the local […]

Which of the choices below accurately describes what a drumlin looks like? A drumlin is a smooth, elongate, asymmetrical hill composed of till. A ground moraine is a […]
How do you find the instantaneous center of zero velocity?
How do you find the instantaneous center of zero velocity? If vA and vB are not parallel, then the instantaneous center of zero velocity will be at the point of intersection of the two perpendicular lines. What is instantaneous Centre of rotation How do you know the number of instantaneous Centres in a mechanism? 11. […]
What does a series circuit consist of?
What does a series circuit consist of? In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a larger, […]
What disproved the Bohr model?
What disproved the Bohr model? Five years later, the model would be disproved by Hans Geiger and Ernest Marsden, who conducted a series of experiments using alpha particles and gold foil – aka. the “gold foil experiment.” In this experiment, Geiger and Marsden measured the scattering pattern of the alpha particles with a fluorescent screen. […]
What is the first priority for OSHA inspections?
What is the first priority for OSHA inspections? OSHA’s top priority for inspection is an imminent danger-a situation where workers face an immediate risk of death or serious physical harm. Second priority goes to any fatality or catastrophe-an accident that requires hospitalization of three or more workers. When did OSHA start? April 28, 1971, United […]
How is heat transferred by radiation?
How is heat transferred by radiation? Heat transfer by thermal radiation is transfer of heat by electromagnetic waves. It is different from conduction and convection as it requires no matter or medium to be present. The radiative energy will pass perfectly through vacuum as well as clear air. What is an example of heat transfer […]
