Answer:
The value is
Explanation:
From the question we are told that
The diameter of the ring is
The length of the solenoid is
The diameter of the solenoid is
The number of turns is N = 1500
The change in current in the solenoid is
The time taken is
Generally the radius of the ring is
=>
=>
Generally the area of the ring is mathematically represented as
=>
=>
Generally the induced emf is mathematically represented as
Here
Here is the permeability of free space with value
So
=>
So
=>
Some substances look alike and the density can help you determine which is which. It also helps to tell which is heavier than the other.
Answer:
here given is a weight
then force becomes mg
that is F=Mg
=4*9.8
then by using the formula
F=Ma
a=F/M
=4*9.8/9.8
=4
Explanation:
Answer:
the answer is ture
Explanation:
because the energy substances must absorb in order to change from liquid to gas
Answer:
The length is
Explanation:
From the question we are told that
The frequencies of the two successive harmonics are ,
The speed of sound in the air is
Generally the frequency of a given harmonic is mathematically represented as
Here n defines the position of the harmonics
Now since the position of both harmonic is not know but we know that they successive then we can represented them mathematically as
and
So
=>
=>
