Answer:
437.5Kjoules
Explanation:
K.E=half multiply by mass multiply by square of velocity
=437.5Kjoules
<span>In order for
an object to accelerate, a <u>force</u> must be applied. It follows Newton’s second
law of motion where it states that a body at rest remains at rest unless a
force is acted upon it. When you move an object, you are exerting a force onto
it. By exerting a force on the object, you are actually displacing it from its
initial position. You cannot apply force to the object without altering its
position. Keep in mind that when you exert work, you are exerting energy too. </span>
A law has always been observed to be true
Properties that define the light is a wave are
1. Speed : speed of light is 300,000 Km /s, It is most fundamenta property of light to define light is a wave
2. Reflection: Light particles or photons reflect off the particles or masses are continue to travel at the same speed.

The solar system is bounded together by gravity, and is made up of the Sun eight planets and dwarf planets
The correct options are;
- The Sun ⇒ generates energy deep in its core through the fusion of hydrogen and into helium
- Earth ⇒ has a single moon that is surprisingly large compared to its planet
- Saturn ⇒ is orbited by at least two geologically active moons: Titan and Enceladus
- Neptune ⇒ has a large moon, Triton, that almost certainly once orbited the Sun independently
- Venus ⇒ has a surface hot enough to melt led as a result of extremely strong greenhouse effect
- Uranus ⇒ has an axis tilt that gives it very extreme seasons
- Pluto ⇒ was studied up close in 2015 by the New Horizons spacecraft.
- Mars ⇒has no surface liquid water today, but shows clear evidence of such water in the distant past
- Jupiter ⇒ has a famous storm known as the Great Red Spot
- Eris ⇒ is similar in size to Pluto and also considered a dwarf planet
- Mercury ⇒ has a greater difference in temperature between its day and night sides than any other world
Reasons:
The Sun generates energy by nuclear fusion in its cores
The size of the Moon more than a quarter of the Earth's size
Saturn moon Titan shows signs of volcanic activity
The moon Triton rotates in the opposite direction to the rotation of Neptune
Venus is the second closest planet to the Sun with a thick CO₂ atmosphere, resulting in a greenhouse effect that makes the planet 510°C hotter
Uranus has seasons that last for approximately 20 years
The New Horizons spacecraft took 9.5 years to reach Pluto after the mission was launched in 2006
Mars liquid water disappeared billions of years ago
The Great Red Spot storm has lasted for over 300 year
Eris, one of the largest dwarf planets and is further from the Sun than Pluto
The difference in temperature between the day and night sides of Mercury is 427°C - (-180°C) ≈ 607°C
