Answer:

7.5 m/s²

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 21 m/s

Final velocity (v) = 36 m/s

Time (t) = 2 secs

Acceleration (a) =..?

The acceleration of an object is simply defined as the rate of change of velocity of the object with time. Mathematically, it is represented as:

Acceleration (a) = (final velocity (v) – initial velocity (u)) / time (t)

a = (v – u)/t

With the above formula, we can determine the acceleration of the roller coaster as follow:

a = (v – u)/t

a = (36 – 21)/2

a = 15/2

a = 7.5 m/s²

Therefore, the acceleration of the roller coaster is 7.5 m/s².

A. what is the e value for the oxidation of cytochrome c by the cua redox center in complex iv when the ratio of cyt c (fe3 ) /c
mariarad [96]

0.116 V is the e value for the oxidation of cytochrome c by the cue redox center in complex iv when the ratio of cyst c (fe3 ) /cyst c (fe2 ) is 20 and the ratio of cue (cu2 )/cue (cu ) is 3.

<h3>Explain the process of oxidation of cytochrome c.</h3>

When cytochrome c is oxidized by mitochondrial cytochrome oxidase (COX), it attaches to Apaf-1 to produce the apoptozole, which activates pro-caspase-9 and causes cell death. Cyst can be created from cytosolic cytochrome c. In the IMS, oxidized cytochrome c can scavenge superoxide without converting it into H2O2, a process that happens naturally but is accelerated by SOD. The benefit of scavenging superoxide independently of H2O2 synthesis is reducing the possibility of hydroxyl radical generation via the Fenton reaction.

How can you drop two eggs the fewest amount of times, without them breaking? Whoever gets this right I will mark them brainlyest
Alekssandra [29.7K]

Answer:

Okay well simply drop it from one inch on to the ground and it won't break and you could put it into a basket with bubble wrap.

Explanation:

Well if you wrap the egg into bubble wrap a few times them put it into a basket (its your choice) then it won't break because the bubble wrap will just pop a few times but sometimes it depends on where you are dropping it from.

Have a blessed day bye! ;)
