PART A)
Conductivity of insulator is very small as there is no free electrons to conduct the current trough that medium
So here number of conduction electrons are very less in insulators
PART B)
Resistance is the property of a conducting medium which will oppose the flow of current trough it
Resistance of wire directly depends on its length so resistance of long wire will be more than the resistance of short wire
Resistance inversely depends on the area so if a wire has more crossectional area then its resistance must be small
PART C)
power of light bulb is defined as rate of electrical energy
it is given by formula
P = i V
here we know that
i = 1.46 A
V = 120 volts
so power is given as
yes it does it because the material cause it to refract and the stronger it is the more it will refract
Answer:
The new period will be reduced by 50%
Explanation:
The period of pendulum is given by;
When the length is decreased by 25%, the new length L₂ is given by;
L₂ = 25/100(L₁)
L₂ = 0.25L₁
Thus, the new period will be reduced by 50%
Answer:
Meandering
Explanation:
A meander is known as the continuous flow of regular curves which are sinuous, loops, turns, bends or winding in the channel of river
Production of a meander by a river or stream as it erodes the sediments comprising on an exterior, a concave bank and deposits it and other sediment on the downstream on an interior, convex bank which is like a point bar.
Rivers or streams with a one channel and sinuosities of 1.6 or more are defined as meandering rivers or streams.
Answer:
Yes
Explanation:
Yes, bluetooth devices work in a frequency range between 2.4 - 2.485GHz. Outside this frequency the devices will not communicate with each other correctly. This frequency equals a wavelength of around 1cm. Therefore, any change in the amplitude or wavelength would need to be in relation to each other in order to maintain the frequency in the required range for the bluetooth device to work accordingly. If one increases while the other remains the same it can easily change the frequency to outside the range.
