Condensation of DNA forms the chromosomes and the DNA contains the genes.

<h3><u>Explanation:</u></h3>

DNA is the complex polymer of different nucleotides which stores the genetic information inside each and every cell of an animal. A DNA molecule is very long, which is stored inside the nucleus of an eukaryotic cell. In case of prokaryotic cells, the DNA molecule remains present inside the cytoplasm of a cell.

The Chromosomes are the condensed DNA which are seen inside the cells which are going to divide in near future. In these cells for the sake of efficient chromosome separation, the DNA condenses into chromosomes with the help of different histone and non histone proteins.

Genes are particular parts of DNA which comprise of a group of nucleotides and together, they translate into a protein chain with specific function in body.

Answer:

378 KWh

Explanation:

We'll begin by converting 1.2×10³ W to KW. This can be obtained as follow:

10³ W = 1 KW

Therefore,

1.2×10³ W = 1.2×10³ W × 1 KW / 10³ W

1.2×10³ W = 1.2 KW

Next, we shall convert 6.3×10² mins to hours (h). This can be obtained as follow:

60 mins = 1 h

Therefore,

6.3×10² mins = 6.3×10² mins × 1 h / 60 mins

6.3×10² mins = 10.5 h

Finally, we shall determine the electrical energy in KWh used for 1 month (i.e 30 days). This can be obtained as follow:

Power (P) = 1.2 KW

Time (t) for 1 month (30 days) = 10.5 h × 30

= 315 h

Energy (E) =?

E = Pt

E = 1.2 × 315

E = 378 KWh

Thus, the electrical energy used for 1 month (i.e 30 days) is 378 KWh.

When you push on an object such as a wrench, a steel pry bar, or even the outer edge of a door, you produce a torque equal to th

Korvikt [17]

<span>Since youc oncetrate all your force directly towards the moment arm it means that you push it at an angle of your force is directed to the left or the right and I bet that it must be 90</span> degrees to the bar. Obviuosly, if you are about to push it you will do it straight up but not in a zig zag way. In other words, it should be perpendicular to the arm because the<span> torque can be produced only if force is applied at a constant index (90).

A student plucks a fixed-end string, creating a standing wave with 6.00 nodes (including any nodes at the ends). The string is t

Vesna [10]

1) 2.5 wavelengths

2) 0.208 m

3) 1731 Hz

Explanation:

Standing waves are waves that do not propagate, but instead the particles of the medium just oscillate around a fixed position. Examples of standing waves are the waves produced on a string with fixed ends.

The points of a standing wave in which the amplitude of the oscillation is always zero are called nodes.

The two fixed ends of the string are two nodes. In this problem, we have a total of 6 nodes along the string: this means that there are 4 additional nodes apart from the two ends of the string.

Therefore, this also means that the string oscillate in 5 different segments.

One wavelength is equal to 2 segments of the oscillation: therefore, since here there are 5 segments, this means that the number of wavelengths that we have in this string is

$n=\frac{5}{2}=2.5$

The wavelength of a wave is the distance between two consecutive crests (or throughs) of the wave.

The wavelength of a standing wave can be also measured as the distance between the nth-node and the (n+2)-th node: so, basically, the wavelength in a standing wave is twice the distance between two nodes:

$\lambda = 2 d$

where

$\lambda$ is the wavelength

d is the distance between two nodes

Here the length of the string is

L = 0.520 m

And since it oscillates in 5 segments, the distance between two nodes is

$d=\frac{L}{5}=\frac{0.520}{5}=0.104 m$

And therefore, the wavelength is

$\lambda=2d=2(0.104)=0.208 m$

The frequency of a wave is the number of complete oscillations of the wave per second.

The frequency of a wave is related to its speed and wavelength by the wave equation:

$v=f\lambda$

where

v is the speed

f is the frequency

$\lambda$ is the wavelength

In this problem:

v = 360 m/s is the speed of the wave

$\lambda=0.208 m$ is the wavelength

Therefore, the frequency is

$f=\frac{v}{\lambda}=\frac{360}{0.208}=1731 Hz$

The equivalent capacitance between point a and b is 5.87μf.
The charge at 20μf is 93.92 μC.
The charge at 6μf is 67.8 μC.
The charge at C and 3μf is 26.12 μC.

<h3>Sum of capacitance of C and 3μF</h3>

The sum of the capacitance is calculated as follows;

1/Ct = 1/C + 1/3

1/Ct = 1/10μf + 1/3μf

1/Ct = (3μf + 10μf)/30μf²

1/Ct = 13μf/30μf²

Ct = 30μf²/13μf

Ct = 2.31μf

<h3>Total capacitance in parallel arrangement</h3>

The total capacitance in parallel arrangement is calculated as follows;

Ct = 2.31μf + 6μf = 8.31μf

<h3>Equivalent capacitance between point a and b</h3>

1/Ct = 1/8.31μf + 1/20μf

1/Ct = 0.1703

Ct = 5.87μf

<h3>Charge flowing in each capacitor</h3>

Maximum voltage is delivered in 20μf, q = CV

<u>charge for 20μf:</u>

q = (5.87 x 16)μC

q = 93.92 μC

<h3>Equivalent capacitance for C, 3μf and 6μf</h3>

Ct = 2.31μf + 6μf = 8.31uf

<u>charge for 6μf:</u>

q = (6/8.31) x 93.92μC

q = 67.8μC

<h3>Total charge for C and 3μf</h3>

q = 93.92μC - 67.8μC = 26.12 μC

charge for C = charge 3μf = 26.12 μC
