Answer:
The magnetic field at the center of a circular loop is .
Explanation:
Given that,
Radius = 4.0 cm
Current = 2.0 A
We need to calculate the magnetic field at the center of a circular loop
Using formula of magnetic field
Where, I = current
r = radius
Put the value into the formula
Hence, The magnetic field at the center of a circular loop is .
The correct answer to the question is: A) Parallel circuits.
EXPLANATION:
There are normally two types connection of circuit elements which are preferred for connection of electrical appliances.
Most of the circuits in home are connected to each other in a parallel way.
We know that the potential remains constant at every circuit elements for parallel connection. The potential drop across each circuit element will be different for series connection.
Due to the parallel connection, each circuit elements can be switched on or off separately.
Hence, most of the electrical circuits in home are connected in parallel way.
Explanation:
Given that,
Wavelength of the laser light,
The laser pulse lasts for,
(a) Let d is the distance covered by laser in the given by,
d = 0.0102 meters
Let n is the number of wavelengths found within the laser pulse. So,
n = 9604.51
(b) Let t is the time need to be fit only in one wavelength. So,
Hence, this is the required solution.
Answer:
Explanation:
Remark
Anybody who has dealt with Christmas Tree lights knows what can be done. You must take a bulb you know to be good and try each bulb in turn until the whole string lights up. If two bulbs are dead, give up and go buy another string. Two bulbs create a lot of combinations.
The circuit is a series circuit.
Since q=mct, and q is heat ENERGY, masses and specific heat are equal, Temperature is the determining factor here. So as the equation suggests, liquid water has more energy as it contains more heat energy.
