How does current change if resistance is doubled? if resistance is doubled then the current would be halved as resistance is inversely proportional to the current flowing in a circuit. that is if the resistance is doubled the current would be halved. What happens to resistance when voltage is doubled? So doubling or tripling the […]

How long does it take for rust to eat through metal? Steel is a metal that holds a lot of iron, and let’s say, for instance, that steel is constantly surrounded by environmental factors like water and oxygen, the steel may start to see signs of rust in as little as 4-5 days. Can you […]

What are goals of power system? The goals of power system analysis are the following: To model or to execute per phase analysis of power system components. To monitor the voltage at different buses, real and reactive power flow between buses. To plan future expansion of the current system. What are the major components of […]

What is the difference between a law and a theory explain? Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, whereas theories describe how the phenomenon happens. What do hypothesis and theory have in common? In science, a theory is a tested, well-substantiated, unifying explanation for a set […]

Where do polar easterlies occur? Polar Easterlies- Polar Easterlies can be found at the north and south poles and they are cold and dry because of where it is located, which is at high latitudes. This type of wind system forms when cool air, at the poles, and then transfers to the equator. What is […]

Is a capacitor a high pass filter? A capacitor can be used as part of a high pass, low pass, or band pass filter, depending on how it’s connected to other parts. For example, a capacitor with a resistor can be a high pass filter: or a low pass filter: Even that by itelf is […]

Which perspective considers the relationship between individuals? Contextual perspective considers the relationship between individuals and their physical, cognitive personality, and social words. Contextual perspective is one of the modern psychological perspectives. The psychodynamic perspective is based on Sigmund Freud thought. What are some current issues in lifespan development? Four important issues in lifespan development are […]

Which air is lighter warm or cold? Hot air is lighter than cold air. The reason fr this is when air gets heated up it expands and becomes less dense than the air surrounding it also the distance between the molecules increases. So the less dense air floats in the much denser air just like […]

What do you understand by frequency and time? Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so […]

What are the 5 examples of transitions? 10 Types of Transitions Addition. “Also, I have to stop at the store on the way home.” Comparison. “In the same way, the author foreshadows a conflict between two minor characters.” Concession. “Granted, you did not ask ahead of time.” Contrast. “At the same time, what she said […]
