Does current stay the same in a parallel circuit? Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. If one of the parallel paths is broken, current will continue to flow in all the […]

Why does a light bulb not follow ohms law? Resistance of non-ohmic components An example of this is the filament light bulb, in which the temperature rises as the current is increased. Here, Ohm’s law cannot be applied. If the temperature is kept constant for the filament, using small currents, then the bulb is ohmic. […]

How many types of motion does the Earth show name them? As you know that the earth has two types of motions, namely rotation and revolution. Rotation is the movement of the earth on its axis. The movement of the earth around the sun in a fixed path or orbit is called Revolution. Can a […]

Is 20 dB twice as loud as 10dB? A 20 dB sound is 10 times louder than a 10 dB sound. The level of noise in a quiet bedroom, 30 dB, is 100 times louder than 10 dB. And 40 dB is 1,000 times louder than 10 dB. A typical conversation clocks in at around […]

Amazon: 4,000 miles. Yangtze: 3,915 miles. Which is the third largest river in the world? […]

Why do gases have low potential energy? However, when gas molecules absorb energy they Do increase in kinetic energy. Therefore, as its kinetic energy increases and the molecules accelerate in random directions the lose potential energy in a closed system where they have a very little amount of force subjected to them by intermoleculer forces. […]

Why does C2 have both pi bonds? Closed 3 years ago. C2 molecules have been found in vapour state. Their double bonds are made of two pi bonds because four electrons need to be accomodated in each bond. So this is against the rule that there must be a sigma bond before a pi bond […]

What shape is the cross section of a rectangular pyramid? triangle What is the shape of the cross section taken parallel to the base of a square pyramid 1 point? When we take a cross section of a pyramid parallel to the square base, means that we are creating a new base for the same […]

How much light can a fiber optic cable carry? 3. Indoor lights. The last major components of a solar fiber system are the lights themselves. Light can travel up to a few hundred feet through fiber optic cables, and at the end of each cable is a lighting apparatus that disperses sunlight, just like a […]

What is required by osmosis? For osmosis to occur the membrane must be permeable to water but impermeable to the solute and the concentration of the solute must be different on the two sides of the membrane. The pressure that is just sufficient to prevent water from moving across the membrane is referred to as […]
