Do forces cause some change in motion? Force is defined as a push or pull on an object. Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of […]

What force twists a material by turning the ends in opposite directions? Torsion forces twist a material by turning the ends in opposite directions. What is internal and external force? • Internal Forces: Forces which act on one part of an object. by another part of the same object. • External Forces: Forces which act […]

The seven metalloids are boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. The three types of elements occupy their own places in the Periodic Table.

How do you calculate emergent rays? As the ratio of refractive indices of air and the glass slab remains the same in both cases (though their value gets inverted), the emergent ray is parallel to the incident ray. Therefore, angle of emergence ′e′ is equal to the angle of incidence ′i′. How do you solve […]

What is line shape in laser? When a radiation is incident the strength of interaction of this energy state with radiation is a function of frequency. This function is called the line shape function. The line shape function is represented by g( ). This function is usually normalized according to the relation. What is the […]

How can you determine whether green or yellow is the dominant allele? Since all the heterozygous offspring are yellow, then the yellow allele must be dominant over the recessive green allele. The green allele didn’t disappear; its effect is not seen in heterozygotes. Peas are yellow when they have either two yellow alleles . . […]

Are triceps fast or slow twitch? Take home message. The triceps is composed of 67% fast twitch fibers, so train it according to the adage, “go heavy or go home.” The long head needs to be trained with overhead work. Are fast twitch muscles bigger?

Is there undersea landslide? Underwater landslides are common features on steep continental margins. Underwater (also called submarine) landslides rapidly shape the seafloor environment by transferring large quantities of sediment and rock downslope from the continental shelf into the deep ocean. Has Texas ever had a tsunami? Today, 3 News sat down with a geologist at […]
