Answer:
7 hectometers is 7000 decimeters
T = 2*pi*Sqrt (L/g)
T = Period = Time to complete one oscillation, L = Length of the pendulum, g = gravitational acceleration.
Then,
L = {T/(2*pi)}^2*g = {7/(2*pi)}^2*3.711 = 4.606 m
Answer:
A. John Tyndall
Explanation:
In 1887, John Tyndall confirmed the theory of <u>biogenesis</u>, formulated by Luis Pasteur in 1864, applying sterilization by <u>discontinuous heating</u>, a process that is currently known as tyndalization. Evidence of the existence of resting microbacterial forms, very resistant to heat.
Thanks to this demonstration he is recognized as the <em>father of microbiology</em> with Pasteur. The theory brought down the previous idea of the Spontaneous Generation, which remained in force since 1745.
