Answer:
<h3> b. 1.18</h3>
Explanation:
The fundamental frequency in string is expressed as;
F1 = 1/2L√T/m .... 1
L is the length of the string
T is the tension
m is the mass per unit length
If the tension is increased by 40%, the new tension will be;
T2 = T + 40%T
T2 = T + 0.4T
T2 = 1.4T
The new fundamental frequency will be;
F2 = 1/2L√1.4T/m ..... 2
Divide 1 by 2;
F2/F = (1/2L√1.4T/m)/1/2L√T/m)+
F2/F = √1.4T/m ÷ √T/m
F2/F = √1.4T/√m ×√m/√T
F2/F = √1.4T/√T
F2/F = 1.18√T/√T
F2/F = 1.18
F2 = 1.18F
Hence the fundamental frequency of vibration changes by a factor of 1.18
Food has calories which feeds your bones in your body from eating away your muscles, it doesn’t have “energy” on the other hand pop and drinks do.
The approach that has been made because of the psychological disorder has the diagnosis that conforms the biological approach. The biological approach is a way of approaching a person with the use of their emotions and behaviors. This approach is usually used in psychology.
Explanation:
when we go outside, heat up food in the microwave, etc. it exposes us to radiation. along with things like radiators. the sun has lots of radiation and heat, so going outside exposes us. the microwave has radiation that heats up our food. the radiation from a microwave is not healthy for us, and is slowly poisoning us each day we use it. but as long as we do those things, we are exposed.
hope this helps
