suter [353]

The answer is confirmation bias. This is the tendency to look for evidence that will confirm ones hypothesis and ignoring anything else that does not lead to the hypothesis. In this situation confirmation bias is evident due to the fact that you look for anything that confirms your hypothesis and ignore anything else that does not point to drug abuse.

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

Have a nice day!

Stem color of tomato plants is known to be under the genetic control of at least one pair of alleles such that A- results in the

fredd [130]

Answer:

Genotype - AaMm

Phenotype - Heterozygous purple stem and fruit with two locules

Explanation:

Given

Trait 1 - Recessive allele for green color stem is represented by a

and dominant allele for purple color stem is represented by A

Trait 2 - Production of two locules in the tomato fruit is a dominant trait and is represented by "M" and production of multiple locules in the tomato fruit is a recessive trait and is represented by "m"

F1 cross is carried between tomato plant with purple stem and fruit with two locules (AAMM) and a tomato plant that have fruit with multiple locules and a green stem (aamm)

The following offspring will be produced

AM AM AM AM

am AaMm AaMm AaMm AaMm

am AaMm AaMm AaMm AaMm

am AaMm AaMm AaMm AaMm

am AaMm AaMm AaMm AaMm

Genotype - AaMm

Phenotype - Heterozygous purple stem and fruit with two locules
