Answer:
the answers D all of the above
The baseball of mass 140g travels at a speed of 30 m/s.
Its momentum is
P₁ = (140 x 10⁻³ kg)*(30 m/s) = 4.2 (kg-m)/s
Part a.
The momentum is dissipated in 1.5 s.
The average force, F, that dissipates the momentum is
(F N)*(1.5 x 10⁻³ s) = 4.2 (kg-m)/s
F = 2800 N = 2.8 kN
Answer: 2.8 kN
Part b.
The average force that the baseball exerts on the head is 2.8 kN, as obtained in part a.
This is true if the time to dissipate the momentum is 1.5 ms.
Answer: 2.8 kN
Part c.
Answer:
(a) The forehead will not fracture because 2.8 kN < 6.0 kN.
(b) Your cheek will fracture because 2.8 kN > 1.3 kN
Answer:
OPTION A= enzymes
Explanation:
The removal of microbial products from the environment typically utilizes ENZYMES.
===> what are enzymes?.
Enzymes are are biological catalyst that are produced and found in living things and they work by speeding up or increasing the rate of reaction just like the Chemical catalysts. Enzymes are proteinous, specific in action, and they are large biomolecules.
===> What are microbial products?.
Microbial products are products from microbes. Microbes secretes enzymes. Commercial utilization of microbial products is known as microbial technology.
===> CONCLUSION: The removal of microbial products from the environment typically utilizes ENZYMES.
