These equations calculate kinetic energy and gravitation potential energy.
Kinetic energy (KE) is the energy an object has because of its motion. That’s why it’s calculated using its mass and speed.
Gravitational potential energy (CPE) is the energy an object has due to its position in the gravitational field. This is the energy that can be converted by dropping it or letting it fall which is why the gravitational constant and height as well as mass are needed.
If you have any equations needed to be calculated, I’d be happy to help.
Answer:
2/3 or 3/2
Step-by-step explanation:
Let x represent the number. The given relation is ...
x +1/x = 2 1/6
x^2 +1 = (13/6)x
6x^2 -13x +6 = 0 . . . . . subtract the right side and multiply by 6
(6x -9)(6x -4)/6 = 0 . . . . factor
(2x -3)(3x -2) = 0 . . . . . . simplify a bit
x = 3/2 or 2/3 . . . . . . . . values of x that make the factors zero
The number is 2/3 or its reciprocal, 3/2.
Answer:
C. . how old they are
Step-by-step explanation:
Geologist are people that deal with the internal structure of the earth.
They study Rocks, and it's deposit accumulated millions of years back.
They can also give account of what happened in the past and the types of organisms that existed in the past.
Fossils are traces of event, remains of dead animals and decomposed object.
So geologist can give account of how many years a particular fossil has lived in that particular environment.
7 times 2 will be 14 and 3 times 2 is 6. So you need to add 14 plus 6 and you get 20 :) Hope you enjoy!
