Answer:
A.without a long antenna, 're signal will not travel far
It's 35 degrees IF they have the same declination. If their declinations are different, then the angle between them can be anything from 35 degrees to 180 degrees.
Answer:
391.67Hz
Explanation:
The fundamental frequency formula in string is expressed as;
Fo = V/2L
V is the velocity of the wave = 329m/s
L is the length of the string = 42cm = 0.42m
Substitute
Fo = 329/2(0.42)
Fo = 329/0.84
Fo = 391.67Hertz
Hence the fundamental frequency of a mandolin string is 391.67Hz
Im pretty sure the answer is mutations in the DNA of genes because i believe the other 3 are correct
Answer:
Series equivalent resistance:
Parallel equivalent resistance: 
Explanation:
The equivalent resistance in series circuit is calculated as



The equivalent resistance in parallel circuit is calculated as

Which can be simplified to



The parallel circuit has the higher equivalent resistance as compared to series circuit.
