Answer:

In order from largest to smallest these terms are:

In order from largest to smallest these terms are:Universe
In order from largest to smallest these terms are:UniverseGalaxy
In order from largest to smallest these terms are:UniverseGalaxySolar system
In order from largest to smallest these terms are:UniverseGalaxySolar systemStar
In order from largest to smallest these terms are:UniverseGalaxySolar systemStarPlanet
In order from largest to smallest these terms are:UniverseGalaxySolar systemStarPlanetMoon
In order from largest to smallest these terms are:UniverseGalaxySolar systemStarPlanetMoonAsteroid

In order from largest to smallest these terms are:UniverseGalaxySolar systemStarPlanetMoonAsteroidWe can generally say that a Moon is larger than an asteroid however some moons are quite large while others are smaller than many known asteroids. Asteroids are small rocky bodies that orbit the Sun, while moons are objects that orbit planets. Jupiter and Saturn have attracted many objects out of the asteroid belt and gathered them as moons.

Example of nuclear fission and nuclear fusion

EleoNora [17]

Answer:

In fission, energy is gained by splitting apart heavy atoms, for example uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. However, fusion is combining light atoms, for example two hydrogen isotopes, deuterium and tritium, to form the heavier helium.

Two uniform solid cylinders, each rotating about its central (longitudinal) axis, have the same mass of 3.56 kg and rotate with

Natali5045456 [20]

Answer:

(a) 3107.98 J

(b) 14530.6 J

Explanation:

mass, m = 3.56 kg

angular speed, ω = 179 rad/s

Moment of inertia of solid cylinder, I = 1/2 mr^2

where, m is the mass and r be the radius of the cylinder.

(a) radius, r = 0.330 m

I = 0.5 x 3.56 x 0.330 x 0.330 = 0.194 kgm^2

The formula for the rotational kinetic energy is given by

$K = \frac{1}{2}I\omega ^{2}$

K = 0.5 x 0.194 x 179 x 179 = 3107.98 J

(b) radius, r = 0.714 m

I = 0.5 x 3.56 x 0.714 x 0.714 = 0.907 kgm^2

The formula for the rotational kinetic energy is given by

$K = \frac{1}{2}I\omega ^{2}$

K = 0.5 x 0.907 x 179 x 179 = 14530.6 J

A disc of mass m slides with negligible friction along a flat surface with a velocity v. The disc strikes a wall head-on and bou

qwelly [4]

Answer:

-v/2

Explanation:

Given that:

a disc of mass m

Collides with the wall going through a sliding motion on on the plane smooth surface.

Upon rebounding from the wall its kinetic energy becomes one-fourth of the initial kinetic energy before collision.

We know, kinetic energy is given as:

$KE_i=\frac{1}{2}. m.v^2$

consider this to be the initial kinetic energy of the body.

Now after collision:

$KE_f=\frac{1}{4}\times KE_i$

$KE_f=\frac{1}{4} \times \frac{1}{2}\times m.v^2$

Considering that the mass of the body remains constant before and after collision.

$KE_f=\frac{1}{2}\times m.(\frac{v}{2})^2$

Therefore the velocity of the body after collision will become half of the initial velocity but its direction is also reversed which can be denoted by a negative sign.
