How do you solve concurrent force problems? Resultant of Concurrent Force System Rx=ΣFx=Fx1+Fx2+Fx3+… The x-component of the resultant is equal to the summation of forces in the x-direction. Ry=ΣFy=Fx1+Fx2+Fx3+… The y-component of the resultant is equal to the summation of forces in the y-direction. Rz=ΣFz=Fx1+Fx2+Fx3+… What is Moment force? The Moment of a force is […]
Why does air put pressure on us?
Why does air put pressure on us? Because there is a measurable temperature, the molecules of the atmosphere have energy. These collisions are mostly elastic, meaning the molecules bounce away more than they stick together. The “bounce” is a force. When it is applied over an area, like your skin or the Earth’s surface, it […]
What is an example of acute toxicity?
What is an example of acute toxicity? By sudden or short term-exposures The harmful effects caused by one-time, sudden, high exposures are often called acute toxicity effects. Some examples of acute toxicity are listed below: Inhalation of high concentrations of acid vapours might cause serious burns of the mouth and the airways leading to the […]

What are the 7 carbon stores?
What are the 7 carbon stores? Carbon is stored on our planet in the following major sinks (1) as organic molecules in living and dead organisms found in the biosphere; (2) as the gas carbon dioxide in the atmosphere; (3) as organic matter in soils; (4) in the lithosphere as fossil fuels and sedimentary rock […]
What is the most important difference between the Schachter singer two-factor theory of emotion and the James Lange theory of emotion?
What is the most important difference between the Schachter singer two-factor theory of emotion and the James Lange theory of emotion? The Cannon-Bard theory proposes that emotions and arousal occur at the same time. The James-Lange theory proposes the emotion is the result of arousal. Schachter and Singer’s two-factor model proposes that arousal and cognition […]
What are the three main causes of uneven warming of the earth?
What are the three main causes of uneven warming of the earth? Unequal heating of Earth, atmospheric convection currents, rotation of the earth, Coriolis effect, earth’s orbit on a tilted axis, and the circulation of ocean waters at the surface and deep ocean. What happens to the air pressure as you move from the troposphere […]
Is radioactive decay first order?
Is radioactive decay first order? Because radioactive decay is a first-order process, the time required for half of the nuclei in any sample of a radioactive isotope to decay is a constant, called the half-life of the isotope. Radioactive decay is a first-order process. What is the formula of activity? To find the activity R […]
