1) Explain the term fermentation

2) why is fermentation useful in making wine and beer

Answers

1. Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen. The science of fermentation is known as zymology.

2. In general, the longer that fermentation goes on, the more sugar is converted into alcohol, resulting in a less sweet (or “drier”) and more alcoholic beverage. To produce beer, various grains are used instead of grapes as the source of sugars. ... This drying process converts the starches present in grain into sugars

Answer:

1.) Fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old.

A 2.0-meter length of copper wire is connected across a potential difference of 24 millivolts.
The current through the wire is 0.40 ampere. The same copper wire at the same temperature
Is then connected across a potential difference of 48 millivolts. The current through the wire
is
A)
0.20 A
B)
0.80 A
C)
1.6 A
D)
0.40 A

Answers

Answer:

The current through the wire is equal to 0.8 A.

Explanation:

Given that,

The length of a copper wire = 2 m

Potential difference = 24 mV

The current through the wire is 0.40 A.

The new potential difference is 48 mV.

We need to find the current through the wire.

As the potential difference is doubled for second wire. So the new current will be :

I' = 2I

= 2 × 0.4

= 0.80 A

So, the current through the wire is equal to 0.8 A.

Use the equation d = st, where d = distance, s = speed, and t = time. If you jog
at a speed of 1.5 m/s for 20 seconds, how far do you travel?
A. 13.3 m
B. 30 m
C. 5 m
D. 21.5 m

Answers

Answer:

Distance = 30 meters

Explanation:

Given the following data;

Speed = 1.5 m/s

Time = 20 seconds

To find the distance travelled;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

Making distance the subject of formula, we have;

[tex] Distance = speed * time [/tex]

Substituting into the above formula, we have;

[tex] Distance = 1.5 * 20 [/tex]

Distance = 30 meters

a body of mass 5kg moving on a horizontal ground has a coefficient of friction 0.36.find the normal reaction acting on the body?​

Answers

Answer:

50 N.

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 5 Kg

Coefficient of friction (μ) = 0.36

Normal reaction (N) =?

Next, we shall determine the weight of the body. This can be obtained as follow:

Mass (m) = 5 Kg

Acceleration due to gravity (g) = 10 m/s²

Weight (W) =?

W = mg

W = 5 × 10

W = 50 N

Finally, we shall determine the normal reaction. This can be obtained as follow:

Weight (W) = 50 N

Normal reaction (N) =?

Normal reaction = weight of the body

N = W = 50 N

Thus, the normal reaction acting on the body is 50 N

If a driver makes contact with a steering wheel during a 35 mph crash, she comes to rest in about Δ=15 ms. If, during an identical crash, the driver makes contact with an air bag, she comes to rest in about Δ=110 ms. What is the ratio of the force exerted by the steering wheel to the force exerted by the air bag on the driver?

Answers

Answer:

The ratio of forces is 22 : 3.

Explanation:

Case I:

initial velocity, u = 35 mph

final velocity, v = 0

time, t = 15 ms

Case II:

initial velocity, u = 35 mph

final velocity, v = 0

time, t' = 110 ms

let the mass is m.

According to the Newton's second law, the force is given by the rate of change of momentum.

So

[tex]F =\frac{m(v-u)}{t}\\\\F'= \frac{m(v-u)}{t'}\\\\So, \frac{F}{F'} =\frac{t'}{t}\\\\\frac{F}{F'}=\frac{110}{15}=22:3[/tex]

Answers

Answer:

Explanation:

I'm assuming you missed the decimal point in the initial velocity and that it should be 4.0 m/s. If after a half of a second it is moving a tiny bit slower, it would be because of air resistance. You can only neglect air resistance if the problems you are doing tell you neglect it.

A deer walks 17.0 m south and then 12.0 m north. Find both the magnitude of its displacement and the distance traveled.



A)

5.0 m, 29.0 m


B)

5.0 m, 5.0 m


C)

29.0 m, 29.0 m


D)

29.0 m, 5.0 m

Answers

Answer:

Explanation:

Displacement involves direction and distance.  In this case, the deer has walked a distance of 17 + 12 = 29m but because of the South-then-North direction, the net displacement is only 17-12 = 5m.

So the answer is A)   5.0 m, 29.0 m

South=17mNorth=12m

Displacement:-

17-12=5m

Distance:-

17+12=29m

In an experiment, 120 g of ice at 0 °C is to be melted. The specific latent heat of
ice is 340 J/g. Assume that all the energy from the heater will be used to melt
the ice.
Q1) Calculate the expected time for which the 60 W heater is switched on.​

Answers

Answer:

[tex]680\; \rm s[/tex].

Explanation:

Start by finding the total amount of energy required for melting that much ice.

[tex]\begin{aligned}&\text{Energy required for melting ice sample} \\ &= \text{Mass of Ice} \times \text{Specific Latent Heat of Ice} \\ &= 120\; \rm g \times 340\; \rm J \cdot g^{-1} = 4.08 \times 10^{4}\; \rm J \end{aligned}[/tex].

Hence, the heater would need to supply (at least) [tex]4.08 \times 10^{4}\; \rm J[/tex] of energy.

The power of the heater is [tex]60\; \rm W[/tex], which is equivalent to [tex]60\; \rm J \cdot s^{-1}[/tex], In other words, the heater is rated to supply [tex]60\; \rm J[/tex] of energy every second.

Amount of time it takes for the heater to supply [tex]4.08 \times 10^{4}\; \rm J[/tex] at [tex]60\; \rm J \cdot s^{-1}[/tex]:

[tex]\begin{aligned}\frac{4.08 \times 10^{4}\; \rm J}{60\; \rm J \cdot s^{-1}} = 680\; \rm s\end{aligned}[/tex].

Hence, it would take [tex]680\; \rm s[/tex] for the heater to melt the ice if the heater is insulated, and all the energy from the heater went to the ice.
