Answer:
Explanation:
Single-phase transformers can operate to either increasing or decreasing the voltage applied to the primary winding. When a transformer is used to “increase” the voltage on the secondary winding with respect to the primary, it is called a Step-up transformer
The mosquito would have a higher pitch but quiet and the croaking bullfrog would be a lower pitch but loud.
Explanation:
personality is shaped by both genetic and environmental factors. The culture in which you live is one of the most important environmental factors that shapes your personality (Triandis & Suh, 2002). The term culture refers to all of the beliefs, customs, art, and traditions of a particular society. Culture is transmitted to people through language as well as through the modeling of culturally acceptable and nonacceptable behaviors that are either rewarded or punished (Triandis & Suh, 2002). With these ideas in mind, personality psychologists have become interested in the role of culture in understanding personality. They ask whether personality traits are the same across cultures or if there are variations. It appears that there are both universal and culture-specific aspects that account for variation in people’s personalities.follow me
-- "Work" is the product of (force exerted on the object) x (distance the object moves in the direction of the force).
Since the orbit is a circle, the gravitational force toward the center is always perpendicular to the orbit. The object never moves in the direction of the force. If it did, it wouldn't be 'R' away from the center of the circle.
So the product of (gravitational force) x (distance in the direction of the force) is always zero.
-- Even if the orbit ISN't a circle . . . there are some parts of the orbit that aren't quite perpendicular to the gravitational force. If the satellite is traveling through one of those parts AND getting closer to the central body, then gravity is doing positive work on the satellite. If the satellite is traveling through one of those parts and getting FARTHER from the central body, then the satellite is the one doing positive work, and gravity is doing 'negative work'. The work done by gravity ... and the work done by the satellite ... is zero over a complete revolution, although not zero at every point.
This is exactly the definition of a "Conservative Force" ... a force that does zero work through one trip around any CLOSED path. Gravity is a conservative force, and so is the Electrostatic force.
