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 car moves with the speed of 120m/s for 4 minutes ,calculate the distance covered by the car​

Answers

Answer:

960 m

Explanation:

Given that,

Speed = 120 m/sTime taken = 4 minutes

We have to find the distance covered.

Firstly, let's convert time in seconds.

→ 1 minute = 60 seconds

→ 4 minutes = (4 × 60) seconds

4 minutes = 240 seconds

Now, we know that,

Distance = Speed × Time

→ Distance = (4 × 240) m

Distance = 960 m

Therefore, distance covered is 960 m.

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.

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

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.

A fixed mass of gas has a volume of gas of 25cm3. the pressure of the gas is 100kPA. the volume of the gas is slowly decreased by 15cm3 at a constant temperature. what is the change in the pressure of the gas?
a) 67kPA
b) 150kPA
c) 170kPA
d) 250kPA
give reasons

Answers

A fixed mass of gas has a volume of 25 [tex]cm^3[/tex], the pressure of the gas is 100 kPa, the volume of the gas is slowly decreased by 15 [tex]cm^3[/tex] at a constant temperature, and the change in pressure of the gas is 150 kPa, which is option b.

What is the calculation of the change in pressure?

PV = nRT (P= pressure of the gas, V =volume, n = number of moles of gas, R = gas constant, and T =temperature of the gas in kelvin)

Suppose the gas is an ideal gas and that the temperature is constant,

P1V1 = P2V2

Here P1 = 100 kPa, V1 = 25 [tex]cm^3[/tex], V2 = 10 [tex]cm^3[/tex],

100 kPa x 25 [tex]cm^3[/tex] = P2 x 10 [tex]cm^3[/tex]

P2 = (100 kPa x 25 [tex]cm^3[/tex]) / 10 [tex]cm^3[/tex]

P2 = 250 kPa

the change in pressure of the gas is,

ΔP = P2 - P1 = 250 kPa - 100 kPa = 150 kPa

The reason is that when the volume of a fixed mass of gas is decreased, the pressure of the gas increases proportionally, so here assuming that the temperature is constant it is calculated.

Hence, the volume of the gas is slowly decreased by 15 [tex]cm^3[/tex] at a constant temperature, and the change in pressure of the gas is 150 kPa, which is option b.

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

Answer:

50 N.

Explanation:

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

Mass (m) = 5 Kg

Coefficient of friction (μ) = 0.36

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
