Answer:
KE = 7.7160 GJ
Explanation:
given data
mass = 500 kg
radius = 6394 km
acceleration of gravity = 4.09 m/s²
orbital speed = 20,000 km/h = 20000 ×
= 5555.56 m/s
solution
we Kinetic energy is express as
KE = 0.5 × m × v² .................1
here m is mass and v is velocity
put here value and we get
KE = 0.5 × 500 × 5555.56²
KE = 7716061728.400
KE = 7.7160 GJ
Answer:
An atom with a closed shell of valence electrons (corresponding to an electron configuration s2p6) tends to be chemically inert. An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion.Explanation:
That would be false because a hypothesis is a testable educated guess
and when investigating, they make guesses to what happened then they try to solve it.
The interaction of light that distorted the image of where Bill's goggles appear to be is Refraction.
<h3>
What happens to the speed of light when it hits water in a swimming pool?</h3>
The light slows down when it passes from the less dense air into the water, this slow down of the ray of light which causes the ray of light to change direction and then the changes the speed of the light that causes refraction.
The swimming pool appears shallow than it appear to be because the rays of light coming from the bottom of the swimming pool that is refracted by the water making the height of the swimming pool to be above the actual swimming pool bed and there by misleading the observer(Bill).
