Explanation:
KE = 1/2 mv²,
where KE is the kinetic energy,
m is the mass,
and v is the velocity.
Given m = 1500 kg and v = 30 m/s:
KE = 1/2 (1500 kg) (30 m/s)²
KE = 675,000 J
KE = 675 kJ
The answer is B) comets.
all planets look as though they lie along a flattened circular plane or disk
the Sun and planets rotate in the same direction
all moons orbit planets in a counterclockwise direction
Our solar system is made up of an ordinary star known as the Sun. All moons orbit planets in a counterclockwise direction are not one of the observed characteristics of our solarsystem.
Our solar system is made up of an ordinary star known as the sun, as well as the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
It contains the planets' satellites, as well as countless comets, asteroids, and meteoroids, as well as the interplanetarymedium.
When viewed from the Northpole or the North star Polaris, the Moon and all other typical non-asteroid size moons in our solar system orbit their host planet in a counter-clockwise manner.

The answer is: all moons orbit planets in a counterclockwise direction
b. If you have an accompanying licensed driver
c. If you drive on less traveled roads
d. If you get permission from the local police
When a driver's license is suspended, typically, one cannot drive. However, one might be able to drive under certain conditions, like obtaining an essential need driver license or a hardship license. Laws vary by location, hence local transportation operating rules must be consulted.
When your driver's license is suspended, under most jurisdictions you are generally not allowed to drive. However, there can be certain exceptions to this rule. The correct answer among the provided options would be (a) If you obtain an essential need driver license. This type of license, also referred to as a hardship or restricted license, may allow you to drive under certain conditions, for instance, for work or medical appointments. It's important to note that laws may vary by location, so it is always important to consult with local legal sources or transportation departments to understand specific regulations and processes related to obtaining conditional driving permissions when your license is suspended.

Sound waves travel fastest through the ground.
A longitudinal wave is a form of wave in which the medium vibrates parallel to the direction of the wave.
Here,
The displacement of the medium moves with the wave motion in the same direction.
Sound waves are longitudinal waves because, the direction of the energy transport is parallel to the oscillations of the sound waves.
Since, it is created by compressions and rarefactions in the air, sound waves are known as longitudinal waves. The air particles vibrate in a direction that is parallel to the direction of propagation.
The sound waves require a medium to propagate.
Solids and liquids have the quickest sound wave propagation rates, whereas gases have the slowest. Gases are very loosely packed while liquids are not as securely packed as solids. Sound moves through solids much more quickly than it does through gases due to the distance between the molecules.
Hence,
Sound waves travel fastest through the ground.

Answer: The correct option is the ground.
Explanation:
Sound is a longitudinal wave. In longitudinal wave, the particles vibrate parallel to the direction of the propagation of the wave.
It needs medium to travel. It can travel in solid, liquid and gas.
Sound wave travels faster in solid in comparison to liquid.
It travels slowest in air.
Ground is a denser medium. Here, the sound wave travels faster in comparison to the ocean and the air.
Therefore, the correct answer is the ground.
