What is true weightlessness?
The true weightlessness can only be achieved when two identical gravitational forces act on an object and cancel the effect of each other out.
Is the kilowatt apparent power?
According to Wikipedia, all forms of power can be expressed in Watts, but typically one expresses only REAL Power in Watts (& Kilowatts).The standard is to express Apparent Power in Volt-Amperes (VA) (& KVA).The kilowatt is the unit of measure for true power; apparent power is measured in volt amperes.However, the volt ampere and the reactive volt ampere (for reactive power) are traditional units, used to help differentiate between apparent, true, and reactive power. SI recognises the watt as the unit for each.
What does the apparent motion of objects in the sky depend?
The apparent motion of objects in the sky depends on the motions of Earth.
Is it true or false sound can be perceived differently between younger and older people?
true
Can objects be weightless?
Yes. An object is weightless if gravity is the only force acting on it. (for example, a ball falling in a vacuum) There is no true "weightlessness", because, even if two masses are separated by billions of light years, there is still a gravitational attraction force. There is a distance at which this cannot be felt anymore, but there is still a force.
What is true weightlessness?
The true weightlessness can only be achieved when two identical gravitational forces act on an object and cancel the effect of each other out.
Is it true or false that radar cannot distinguish between storms of differing intensities?
True
What criteria is used to distinguish between a true solution and collide?
tyndall effect
If the distance between us and a star is doubled the apparent brightness is decreased by a factor of four true or false?
True!
What affect the phase angle?
Apparent power is the vector sum of a load's true power and its reactive power. If you draw a 'power diagram', the phase angle will be the angle between the true power and the apparent power. If true power is fixed, then increasing the phase angle will result in a greater value of apparent power.
Why power factor expressed in cosine angle?
The vector-relationship between apparent power, true power, and reactive power is represented by a right-angled triangle, whose hypotenuse represents apparent power and whose adjacent represents true power. Since power factor is defined as 'the ratio of true power to apparent power', you will find that this ratio corresponds to the cosine of the angle between them.
Catabolism and anabolism are the two phases of metabolism?
is the distinguish the distance between the end! :D
What is difference between apparent and intrinsic solubility?
Apparent solubility represents the solubility one observed during the experiment while the intrinsic solubility meant to the real or true solubility.
Which Criteria used to distinguish between true solution and colloids as no residue is left on filter paper on filtration?
In true solution the molecules of the solute get equally distributed throughout the solvent in the atomic level i.e. at the distance of diameter of an atom. While in colloides the molecules are not mixed in such state. So, using this as a principal to distinguish between colloide & solution. We can centrifuge the two mixtures to distinguish the colooide & solution.
An apparent contradiction that is actually true is a?
"Less is more." This phrase might seem contradictory at first glance, but it's true in cases where simplicity or minimalism can lead to better outcomes or understanding. Sometimes, having less of something can actually result in a more meaningful or impactful experience.
Why power factor using cos theta angle?
It's actually cos phi, where the Greek letter, 'phi', is the symbol for phase angle -the angle by which a load current lags or leads the supply current in an a.c. system (the Greek letter, 'theta', is used for the displacement of instantaneous values of current or voltage from the origin of a sine wave).The reason why power factor is a cosine requires you to understand the relationship between apparent power, true power, and reactive power. Apparent power is the vector sum of true power and reactive power, and can be represented, graphically, by the so-called 'power triangle'. In the power triangle, true power lies along the horizontal axis, reactive power lies along the perpendicular axis, and the apparent power forms the hypotenuse, and the angle between true power and apparent power represents the phase angle. By definition, power factor is the ratio between true power and apparent power, and this ratio corresponds to the cosine of the phase angle.From this, we can conclude that true power = apparent power x cos phi, where 'cos phi' is the 'factor' by which we must multiply apparent power to determine true power -i.e. the 'power factor'.
What is the ratio of apparent power to true power?
The ratio of apparent power to true power is called 'admittance', expressed in siemens. Admittance is the inverse of impedance.
