The relationship between acceleration, velocity and radius is given as:

a = v^2 / r

 

Since we are given a diameter of 45 m, hence the radius is 22.5 m.

a = (16 m/s)^2 / 22.5 m

a = 11.38 m/s^2

 

In 2 significant figures:

<span>a = 11 m/s^2</span>

How does one get 8.0 A? The answer is D
ra1l [238]

I don't know why the answer is D , because I can't see the list of choices.


The only way to get 8.0 Amps is by making a serious mistake.

The current in the second picture is 4.0 Amps.


If the resistors are identical, then the effective resistance of

two resistors in parallel is 1/2 the resistance of each one.


The resistance in the second picture is 1/2 the resistance

in the first picture.


Current = (voltage) / (resistance)


Cutting the resistance in half causes the current to double.


If the current was 2.0 Amps in the first picture, it's 4.0 Amps

in the second picture.

An organism's scientific name consists of...
Finger [1]

Answer:

binomial nomenclature.

Explanation:

This means that an organism's scientific name is a combination of two terms.

The first is the name of the organism's genus, and the second is the name of the organism's species

together the genus and the species create the name of a single organism.

A sled with a mass of 20 kg slides along frictionless ice at 4.5 m/s. It then crosses a rough patch of snow that exerts a fricti
Ugo [173]

Use Newton's second law to determine the acceleration being applied to the sled. There are three forces at work on the sled (its weight, the force normal to the ground, and friction) but two of them cancel, leaving friction as the only effective force. This vector is pointed in the opposite direction of the sled's movement, so if we take the direction of its movement to be the positive axis, we would find the acceleration due to the friction to be

\vec F_G+\vec F_N+\vec F_F=m\vec a\iff-12\,\mathrm N=(20\,\mathrm{kg})a\implies a=-0.6\,\dfrac{\rm m}{\mathrm s^2}

Now we use the formula

{v_f}^2-{v_i}^2=2a(x_f-x_i)

to find the distance it travels. The sled comes to a rest, so v_f=0, and let's take the starting position x_i=0 to be the origin. Then the distance traveled x_f-x_i=x_f is

-\left(4.5\,\dfrac{\rm m}{\rm s}\right)^2=2\left(-0.6\,\dfrac{\rm m}{\mathrm s^2}\right)x_f\implies x_f\approx17\,\mathrm m
