What are the similarities between resultant and Equilibrant forces? Resultant is a single force that can replace the effect of a number of forces. “Equilibrant” is a force that is exactly opposite to a resultant. Equilibrant and resultant have equal magnitudes but opposite directions. What is the space diagram? A drawing of a structure that […]

How do you determine incidence? Therefore, the term ‘person-year’ was used, which was defined as the number of quarters of the year that a patient was registered in a general practice. Incidence rates were calculated as the sum of all new episodes of illness of a certain disease in 2012 divided by the size of […]

Does oxygen have a fixed shape? The state that a given substance exhibits is also a physical property. Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. (a) Solid O2 has a fixed volume and shape, and the molecules are packed tightly […]

What did Aristotle say about the moon? For Aristotle the moon had been a perfect sphere, and that was how people still saw it in 1609. A perfect sphere, of course, is perfectly smooth. The pure moon was not of base earth. What did ancients think of the moon? Through persistent observation, Anaxagoras came to […]

What is the egg drop problem? Egg dropping refers to a class of problems in which it is important to find the correct response without exceeding a (low) number of certain failure states. In a toy example, there is a tower of n floors, and an egg dropper with m ideal eggs. What does Ojo […]

Can a new moon be seen? New moons generally can’t be seen. They cross the sky with the sun during the day, and the moon’s shadow side is pointed toward Earth. A new moon is visible only during a solar eclipse. How many days full moon lasts? three days Is pournami good or bad? Pournami […]

Can a meteor hit the sun? No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Orbits within in a Kirkwood gap are not stable, and any asteroid whose orbit wanders into such a region will eventually get pulled into a different orbit, which may take it into […]

Can you solve physics problems? Multiply and divide the quantities until the units match the units of the answer quantity. For example, if you’re trying to find Potential Energy (kg*m2/s2) and you have the height (m), mass (kg) and gravitational acceleration (m/s2), you can match the units by multiplying the three quantities (m*kg*m/s2=kg*m2/s2). How do […]

What is the first step in responding to any sports injury? Explain why the first step in responding to any sports injury is to remove the danger that lead to the injury. When someone sustains an injury while participating in sports, that indicates that something unexpected has occurred. How does compression help swelling? Compression Applying […]
