Answer:
The wavelength is 
Explanation:
From the question we are told that
The frequency of operation of the microwave is 
Generally the wavelength is mathematically represented as

Here c is the speed of light with value 
So

=>
converting to nanometer

Answer:
The resistance of the bulb should be 90
Explanation:
OHMS Law states that the voltage(v) divided by the current (c) in amps (a) will give you your resistance
Answer:

Explanation:
Given that,
Radius of the circular loop, r = 10 cm = 0.1 m
Current flowing in the loop, I = 3.6 A
Uniform magnetic field, B = 12 T
To find,
The magnetic dipole moment of the loop.
Solution,
Let M is the magnitude of magnetic dipole moment of the loop. We know that the product of current flowing and the area of cross section. Its formula is given by :

A is the area of circular wire



Therefore, the magnetic dipole moment of the loop is
. Hence, this is the required solution.
Answer:
Option C
Explanation:
The graph shows endothermic reaction because the reactants are lower in energy and the products are higher is energy. Endothermic reactions absorb energy having products with higher energy.
