I think the main idea is that the middle planets have a solid inner core and that they all could have life on them
Answer:
Explanation:
Thinking process:
Let:
distance = speed × time
for the hare:
for the tortoise:
Let the length of the shell be s. Then the two are related. So:
Let's say the hare ran at x times the speed of the tortoise:
So, the equation still holds :
That latest value for the Angle is in Grads, not in Kilograms.
Apply law of conservation of momentum along vertical direction.
Apply law of conservation of momentum along the horizontal direction
The second ball velocity is 
The magnitud of final total momentum is
The magnitude of final energy is
When the object slides across the rough surface some of its potential energy will be lost to friction.
<h3>Conservation of mechanical energy</h3>
The law of conservation of mechanical energy states that the total mechanical energy of an isolated system is always constant.
M.A = P.E + K.E
When the object slides across the rough surface, some of the potential energy of the object will be converted into kinetic energy while the remaining potential energy will be converted into thermal energy due to frictional force of the rough surface.
P.E = K.E + thermal energy

False. Acids are actually found in the pH range from 0 to 7 and bases are found from 9 to 14. Meanwhile, 7 and 8 are considered neutral.
