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.

Why some air masses are cool, cold, warm, and hot as well as moist or dry?
DENIUS [597]

Answer:

Explanation:

Often times, the property of air masses is a function of where they originate from especially with respect to latitude.

An air mass is certain amount of air with some unique set of temperature and vapor component.

  • Air masses differs from places to places based on where  they originate.
  • Continental air masses are usually dry and cold because there is little to no water on a land mass.
  • Air masses that originates from the surface of the ocean are predominantly moist.
  • In polar regions, the air mass is cold.
  • Around the tropics, they are usually warm due to insolation here.

Tpy6a [65]

Answer:

1)m=89.01 g

2)V(max) = 97.3 cm/s

Explanation:

Given that

K= 15 N/m

The maximum amplitude ,A=7.5 cm = 0.075 m

Given that 31 oscillations in 15 seconds ,this means that frequency f

f=\dfrac{31}{15}

f=2.066 Hz

lets take mass of the ball = m kg

f=\dfrac{1}{2\pi}\times \sqrt{\dfrac{K}{m}}

m=\dfrac{1}{4\times \pi^2}\times{\dfrac{K}{f^2}}

m=\dfrac{1}{4\times \pi^2}\times{\dfrac{15}{2.066^2}}

m=0.08901 kg

m=89.01 g

The maximum speed

V(max)= ω x A

ω = 2π f= 2 x π x 2.066 = 12.98 rad/s

V(max) = 12.98 x 0.075 =0.973 m/s

V(max) = 97.3 cm/s
