While breaking glass with sound is an interesting trick it really takes a lot of effort vibrations diminishes do you to energy being carried away by the sound waves.
Answer:
34.45m
Explanation:
Using the equation of motion formula v² = u²+2as to get the distance travelled
v is the final velocity = 26m/s
u is the initial velocity = 0m/s
a is the acceleration due to gravity = 9.81m/s²
S is the distance travelled
Substituting the given values into the formula;
26² = 0²+2(9.81)s
676 = 0 + 19.62s
19.62s = 676
s = 676/19.62
s = 34.45m
Hence the distance she would travel during the race is 34.45m
Frequency = 1/time period = 1/0.05 = 20s^-1.
J.J. Thomson discovered electrons and noticed that an atom can be divided. Also, he concluded atoms are made of positive cores and negatively charged particles within it.
