The second question is the correct one, as Cere's is in the asteroid belt, and Eris, Make-make, Haumea, and Pluto are in the Kuiper belt.

The answer is "Ceres is found in the asteroid belt and Eris, Makemake, Haumea, and Pluto are found in the Kuiper Belt."


There an as of now five formally grouped dwarf planets in our solar system. They are Ceres, Pluto, Haumea, Makemake and Eris. Ceres is situated inside the asteroid belt between the orbits of Mars and Jupiter, while the other smaller person planets are situated in the external nearby planetary group in, or close to, the Kuiper belt. Another six articles are in all likelihood predominate planets, yet are sitting tight for official grouping, and there might be upwards of 10,000 diminutive person planets in the solar system.

Explain why changing the axis of rotation of an object changes its moment of inertia.
Yuri [45]

The mass distribution along a particular axis affects the moment of inertia.

<h3>What is the moment of inertia?</h3>

Each component of the object's mass is now located at a different distance from the axis than it was previously if the axis is altered. Axes perpendicular to the rod that first travel through its center of mass and then through one of its ends are used to compare the moments of inertia of uniformly stiff rods.

As an illustration, you can easily change the direction of rotation by repeatedly wriggling a meter stick along an axis that passes through its center of mass. You will have a harder time moving the stick back and forth if you shift the axis to the end. Because a major portion of the stick's mass is located farther from the axis, the moment of inertia around the end is much larger.

Pulsars are neutron stars that emit X rays and other radiation in such a way that we on Earth receive pulses of radiation from t
stira [4]

Answer:

(a) a_{c} = 5.41\times 10^{9} m/s^{2}

(b) a_{t} = 2.99\times 10^{- 5} m/s^{2}

Given:

Time period of Pulsar, T_{P} = 33.085 ms == 33.085\times 10^{- 3} s

Equatorial radius, R = 15 Km = 15000 m

Spinning time, t_{s} = 9.50\times 10^{10}

Solution:

(a) To calculate the value of the centripetal  acceleration, a_{c} on the surface of the equator, the force acting is given by the centripetal force:

m\times a_{c} = \frac{mv_{c}^{2}}{R}

a_{c} = \frac{v_{c}^{2}}{R}                (1)

where

v_{c} = \frac{distance covered(i.e., circumference)}{ T}

v_{c} = \frac{2\pi R}{Time period, T}           (2)

Now, from (1) and (2):

a_{c} = R\frac({2\pi )^{2}}{T^{2}}

a_{c} = 15000\frac{2\pi )^{2}}{(33.085\times 10^{- 3})^{2}}

a_{c} = 5.41\times 10^{9} m/s^{2}

(b) To calculate the tangential acceleration of the object :

The tangential acceleration of the object  will remain constant and is given by the equation of motion as:

v = u + a_{t}t_{s} = 0

where

u = v_{c}

a_{t} = - \frac{2\pi R}{Tt_{s}}

a_{t} = - \frac{2\pi 15000}{33.085\times 10^{- 3}\times 9.50\times 10^{10}}

a_{t} = 2.99\times 10^{- 5} m/s^{2}

Directions: I answer all the questions listed below.
anzhelika [568]

Answer:

The compression ratio is 10

Explanation:

Given

V_d = 450cm^3 --- swept volume

V_c = 50cm^3 --- compression volume

Required

Determine the compression ratio (CR)

This is calculated as:

CR = \frac{V_d + V_c}{V_c}

CR = \frac{450+50}{50}

CR = \frac{500}{50}

CR = 10

Analyze why we say an object is accelerating when we usually mean that it is speeding up and an object slowing down also is acce
dem82 [27]

(And don't forget that an object going around a curve at a constant speed is also accelerating.)

I believe there are two reasons:

1). The term is inadequately taught in the American public school system ... along with much of the rest of Science and Math in general.

2). The word became permanently and indelibly corrupted when the automotive industry decided to name the gas pedal the "accelerator".
