Forming ionic bonds study
Answer:
Explanation:
= Length of wire = 65 m
= Initial current = 1.8 A
= Final current = 2.9 A
We know
and
so
The length of the wire remaining on the spool is .
Answer:
option A
Explanation:
the correct answer is option A
The given blanks in the question will be filled with Absolute and relative receptively.
time is absolute means the numerical representation of time example 12:00 pm is absolute time.
Measurement of distance is relative. A relative distance is one which is represented with the reference of some other place, it is not an exact value.
The velocity of the wave on the string is given by
Solving the above equation,
The frequency of the wave 
and wave length is 
The velocity is 
Substituting numerical values,
The length of the string is 
894984+894390548-098548948+8-734897389696563418686528687
