Answer:
m = 4.51 and n = -5
Explanation:
The average magnetic field strength of the Earth is 0.0000451 T. We need to write the value of magnetic field strength of the Earth in scientific notation. In scientific notation, any value is given by :
.........(1)
Where
m is a real number
n is any integer
Here,
.......(2)
On comparing equation (1) and (2), we get the values as :
m = 4.51 and n = -5
Hence, this is the required solution.
Answer:
Acceleration = Force/Mass
Explanation:
Answer:
parallel circuit is a kind of circuits in which all components are connected between the same two sets of electrically common points, creating multiple paths for the current to flow from one end of the battery to the other:
When two sound waves of similar frequency interfere with each other, there is a fluctuating sound heard which is periodic and repeating. This fluctuating sound is called beat. Beat frequency( number of beats per second) is equal to the difference of the frequency of the two sound waves.
So, sound waves of frequency 400 Hz and 404 Hz will produce 4 beats per second.
