13 g —> 0.013 kg
KE = 1/2(m)(v)^2
KE = 1/2(0.013)(8.5)^2
KE = 0.47 J
Answer: A. 24,000,000,000 km
Explanation: An Astronomical Unit commonly abbreviated as AU is the average distance between Earth and the Sun and is about 150 million kilometers.
Astronomical unit is mainly used to measure distances within our solar system.
1 AU is equal to
km
Thus 160 AU is equal to 
Answer and Explanation:
1. Evidence can be observed that light is energy-consuming because the liquid crystal sheet sets the temperature and gets warmer. With this, we can affirm that the light energy, moved the liquid crystal sheet molecules, making them when they move generate heat.
2. The evidence that light loads energy can be seen through the movement of the toy. This is because the light states that there was energy received, which will make all the gear of the toy work and move it.
To solve this problem we will apply the concept given by Pythagoras in the description of the lengths of the legs of a rectangular triangle and if equality against the square of the hypotenuse, that is

Here,
a, b = Legs of a triangle
c = Hypotenuse
According to the attached chart then we would have to

Substituting the given the lengths into the Pythagorean Theorem.

Therefore the distance x is 2830km.
