The warm air will rise because cold air is heavier than warm air.

A 35 kg child moves with uniform circular motion while riding a horse on a carousel. The horse is 3.2 m from the carousel's axis

Andrews [41]

<h2>Hello!</h2>

The answer is:

b. $\frac{2.11m}{s^{2}}$

<h2>Why?</h2>

The centripetal acceleration or radial acceleration is present when an object is moving to describe a circular path. The centripetal acceleration is always perpendicular to the direction of the velocity and going inwards and towards the center.

The centripetal acceleration can be calculated using the following equation:

$CentripetalAcceleration=\frac{v^{2}}{RadiusOfMotion}$

From the statement we know that:

$v=TangentialSpeed=\frac{2.6m}{s} \\R=3.2m$

So, calculating we have:

$CentripetalAcceleration=\frac{{2.6^{2} \frac{m}{s} }}{3.2m}=\frac{{6.76\frac{m}{s} }}{3.2m}=\frac{2.11m}{s^{2} }$

So, the correct answer is:

b. $\frac{2.11m}{s^{2}}$

How is absolute different from a solvent in a solution?

swat32

A simple solution is basically two substances that are evenly mixed together, but the mixture is homogeneous. Meaning, you can no longer tell the two substances apart once they are mixed in solution.
This is because the solute dissolves in the solution.
A solute is the substance to be dissolved (sugar).
The solvent is the one doing the dissolving (water).
As a rule of thumb, there is usually more solvent than solute.The amount of solute that can be dissolved by the solvent is defined as solubility.

Identify how the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes.

kipiarov [429]

The addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.

<h3>What is the relationship between histones and DNA?</h3>

Histones are a family of basic proteins that associate with DNA in the nucleus and help to condense it into chromatin. Nuclear DNA does not appear on free linear strands; it is highly condensed and involves histones to fit inside the nucleus and participate in the formation of chromosomes.

<h3>How does DNA compact with histones?</h3>

Each chromosome is made up of a single molecule of double-stranded DNA wrapped around histones, the nucleosome. This fiber rewinds into a second level of compression, known as the solenoid. Most of the time, cells keep the DNA compacted in the selenoid loops attached to the chromosomal backbone.

Whit this information, we can conclude that the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.
