Rotational slip is the circular movement of the ice in the corrie. What is the difference between a rotational slide and a translational slide? With rotational slumping, heavy rain is absorbed by unconsolidated material making up the cliff (often glacial till, or boulder clay). The cliff face becomes heavier and eventually it separates from the […]

Fast neutrons, on the other hand, play a small role in fission but can transform nuclei of uranium 238 into fissile plutonium 239. What are slow neutrons and why are they important? Slow neutrons allow civilian nuclear reactors to […]

It utilizes the angles theta, the opposite, and adjacent sides to theta, and the hypotenuse. What does Soh mean in Sohcahtoa? It’s a mnemonic device to […]
Pulsed mode means operation of the x-ray system such that the x-ray tube current is pulsed by the x-ray control to produce one or more exposure intervals of duration less than one-half second. What does pulse mean in physics? In physics, a pulse is a generic term describing a single disturbance that moves through a […]
The motion of an orbiting satellite can be described by the same motion characteristics as any object in circular motion. The velocity of the satellite would be directed tangent to the circle at every point along its path. What is satellite definition in physics? A satellite is a moon, planet or machine that orbits a […]
1 / Req = 1 / R1 + 1 / R2 + โฆ. 1 / Rn. The equivalent resistance is always smaller than any of the individual resistances in a parallel circuit. For the example with the three resistors the equivalent resistance is Req=0.82 Ohms. What does req mean in physics? The equivalent resistance (Req) […]
Polar compounds are those with distinct regions of positive and negative charge, as a result of bonding with atoms such as nitrogen, oxygen, or sulfur. Heavy oils generally contain greater proportions of higher boiling, more aromatic, and heteroatom-containing (N-, O-, S-, and metal-containing) constituents. What are polar and non polar substances in physics? Polar molecules […]
Position (x) can be defined as the location of an object at any given time, and Displacement is the change in position of an object. Both of these are vector quantities and have to be measured from the frame of reference. What is a position in motion? The length traveled by an object moving in […]
The primary colors of pigment (also known as subtractive primaries) are used when producing colors from reflected light; for example, when mixing paint or using a color printer. The primary colors of pigment are magenta, yellow, and cyan (commonly simplified as red, yellow, and blue). What are primary and secondary colours in physics? Red, green, […]
Electrical forces result from mutual interactions between two charges. In situations involving three or more charges, the electric force on a single charge is merely the result of the combined effects of each individual charge interaction of that charge with all other charges. What is electric force and its formula? Lesson Summary. The electric force […]
The velocity is said to be uniform if the body covers equal distance in equal interval of time. The velocity is said to be constant if the body moves along a straight line without changing its direction. Acceleration is the rate of change of velocity. What is constant speed with example? Constant speed means the […]
The word physics itself is derived from the Greek word, ฯuฯฮนฯ (phusis) meaning nature. The Greeks gave more than a name to the study of physics for it is with them that the abstract development of physics began. Is physics Greek or a Latin word? physics (n.) Based on Latin physica (neuter plural), from Greek […]
A perpendicular bisector is a line that divides a given line segment exactly into two halves forming 90 degrees angle at the intersection point. The perpendicular bisector of a triangle is considered to be a line segment that bisects the sides of a triangle and is perpendicular to the sides. Where is the perpendicular bisector? […]
