Answer: friction has no role to play in this case. because friction usually occurs between to parts which come in contacts. examples (a)our joints in the human body (b)two mechanical parts (shafts).
Explanation:
However what this topic relates to is gravity. The pebble and paper both weigh one gram, but have different density this is the sole reason why if both are drop from same height the pebble would reach the ground faster than the paper because it is more denser. unlike the paper with a lesser density which would take a longer time to reach the ground.
Answer:
Explanation:
The rms voltage = 140/√2 = 140/1.414 = 99 V.
Reactance of inductor = wL = 2 X 3.14 X 100 X 113 X 10⁻³ =70.96 ohm.
Total resistance in terms of vector = 50+70.96j
j is imaginary unit number
Magnitude of this resistance = √ 50² + 70.96² = 86.80 ohm
current in resistance (rms) ( I ) = 99/86.80 = 1.14 A.
Power dissipated in resistor = I² R = 1.14 X 1.14 X 50 = 65 W( approx)
The largest component of M1 is- Currency.
Answer:
A. Density is proportional to mass and inversely proportional to volume
Explanation:
Density can be defined as the property that matter has, whether solids, liquids or gases, to be compressed in a given space.
The expression that relates the density with the another values is given by,
Where,
(It is directly proportional to the mass of the object)
(It is inversely proportional to the volumen of the object)
<em>Therefore density is directly proportional to the mass and inversely proportional to the volumen.</em>
