Answer:
The mass of object is calculated as 5.36 kg
Explanation:
The known terms to find the mass are:
acceleration of object (a) = 22.35
Force exerted (F) = 120N
mass of an object (m) = ?
From Newton's second law of motion;
F = ma
or, 120 = m × 22.35
or, m= kg
∴ m = 5.36 kg

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.
