the planet neptune

The dwarf planet pluto.

The question literally has the words dwarf planet in it.  Pluto is the only dwarf in the solar system. All you had to do was look up which planet is in front of Pluto.

Answer:

Planet: Neptune

Dwarf Planet: Pluto

Explanation:

Kuiper belt starts just after the orbit of planet Neptune at a distance of around 30 AU (1AU = 150 Million km) and extends up to 50AU from the Sun. This is home to billions of comet as well as lot of rocky bodies. Most famous of them is Pluto, which was earlier designated as a planet. In 2006, when the criteria for declaring a celestial body as a planet were reworked, Pluto was designated as a dwarf Planet.

The comet are thought to have formed at the time of the Solar system formation and resides in Kuiper Belt and Oort's cloud. The comets which reside in Kuiper belt are known as short period or periodic comets.

A carnival Ferris wheel has a 15-m radius and completes five turns about its horizontal axis every minute. What is the accelerat
Tanzania [10]

If a Ferris wheel has a 15-m radius and completes five turns about its horizontal axis every minute then the acceleration of a passenger at his lowest point during the ride is 4.11 \text{m/s}^{2}.

Calculation:

Step-1:

It is given that the radius of the Ferris wheel is r=15 m, and the angular speed of the wheel is \omega=5rev/min.

It is required to find the angular acceleration of a passenger at his lowest point during the ride.

The formula required to calculate the angular acceleration is, a=\omega ^2 r.

Step-2:

Now substituting the given values into the equation to get the value of the angular acceleration.

\begin{aligned}a &=\omega^{2} r \\&=(5 \mathrm{rev} / \mathrm{min})^{2}(15 \mathrm{~m}) \\&=\left(5 \mathrm{rev} / \mathrm{min} \times \frac{\left(\frac{2 \pi}{60}\right) \mathrm{rad} / \mathrm{sec}}{1 \mathrm{rev} / \mathrm{min}}\right)^{2}(15 \mathrm{~m}) \\&=(0.2741 \times 15) \mathrm{m} / \mathrm{s}^{2} \\&=4.11 \mathrm{~m} / \mathrm{s}^{2}\end{aligned}

The acceleration is towards upwards that means towards the center of the wheel.

Choose the items that help to fully describe voltage.
Zina [86]

Answer:

the easy way to describe this is to use a light as an example.

Explanation:

Voltage is pretty much the loop used to help use a lightbulb to emit light. Without voltage, we would be unable to use lightbulbs. This applies to much more than a lightbulb, but it's the easiest way to describe how voltage works.

An apple is dropped from the top of a building and hits the ground 2 seconds later. How tall is the building?
Ket [755]

Hello! :)

\large\boxed{19.6 m}

Use the kinematic equation below to solve for the height of the building:

d = \frac{1}{2} at^{2}

Where:

d = distance, or height of the building (m)

a = acceleration due to gravity (9.8 m/s²)

t = time (seconds)

Plug in the given values into the equation:

d = \frac{1}{2} (9.8)2^{2}\\\\d = \frac{1}{2} (39.2)\\\\d = 19.6 m
