Nuclear reactions in a reactor produce a lot of thermal

Leokris [45]

Answer:

Heat flows from the reactor to the water

Explanation:

The thermal energy mentioned in the description is another way to say heat. The energy that is produced by the nuclear reactions leaves the reactor and enters the water, warming it.

The passage does <em>not </em>say that heat flows in the form of electricity, but rather that the turbines turned by the steam produce electricity.

The passage does <em>not </em>say that the steam produces the heat, but rather that the boiling of the water (caused by the heat) produces steam.

This is a reaction going on in your muscle cells right this very minute:The enzyme triose phosphate isomerase catalyzes this rea

Arisa [49]

Explanation:

The given reaction is as follows.

$E + S \rightleftharpoons ES \xrightarrow[]{k_{2}} E + P$

Here, [E] = triose phosphate isomerase = 0.1 $nm = 0.1 \times 10^{-9}m$

[S] = Dihydroxy acetone phosphate = 5 $\mu m = 5 \times 10^{-6}m$

[P] = Glyceraldehyde-3-phosphate = 2 $\mu m = 2 \times 10^{-6}m$

Therefore, velocity of the reaction will be as follows.

v = $\frac{d[P]}{dt}$ = $\frac{K_{2}[E][S]}{K_{M} + [S]}$

where, $K_{M}$ = Michaelic menten constant = $\frac{K_{1} + K_{2}}{K_{1}}$

v = $\frac{900 \times 0.1 \times 10^{-9}m \times 5 \times 10^{-6}m}{10^{-5} + 5 \times 10^{-6}}$

= $30 \times 10^{-9} m$

or, = 30 nm/s

Hence, we can conclude that the actual velocity of the forward reaction under physiologic conditions if KM = 10 μM is 30 nm/s.

Ivanshal [37]

Answer:

The cost of driving this car is 33.33 miles per dollar.

Explanation:

Distance covered in 1 kilo watt-hour = 4 miles/kWh

Utility company charges = 12 cents/kWh

The cost of driving this car in miles per cents:

$\frac{ 4 miles/kWh}{12 cents/kWh}=\frac{1 miles}{3 cents}$

1 cents = 0.01$

The cost of driving this car in miles per dollars:

$\frac{1}{3} miles/cent=\frac{1 miles}{3\times 0.01\$}=33.33 miles/\$$
