Scientists cannot define life, but they can list characteristics that are true of all life
pychu [463]
What are you asking for here? we need a solid question not a statement.

i'd say that the statement is true. we cant define life because we do not know what life, in essence, is. we can define, however, the characteristice of all living things:
Movement
Respiration
Sensitivity

Nutrition
Excretion
Reproduction
Growth

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}}
