Timothy is slowly walking at a speed of 0920.0 km/s. The circumference of the Earth is 40075000 meters. Over the course of 4320 minutes, how many times does he go around the earth, and what is his total distance in meters?

Timothy travels around the world 595 times and travels a total distance of 2.38x10^10 meters

what does the mitochondria do?

the mitochondria converts glucose into ATP (useable energy)

200

what is an organelle?

organelles are various different objects within a cell that each serve different purposes.

300

what is the difference between pinocytosis and phagocytosis?

pinocytosis brings fluid into the cell through the process of endocytosis whilst phagocytosis brings solids into the cell through the same process of endocytosis.

400

explain the difference between hypotonic,hypertonic, and isotonic

hypotonic is when the concentration of the solution outside the cell is less than the concentration in the cell.
hypertonic is when the concentration of the solution outside the cell is higher than the concentration in the cell.
isotonic is when the concentration outside the cell and in the cell are equal.

500

what happens to an egg (without the shell) when submerged in soy sauce.

due to the solution being hypertonic, the water in the cell goes out of the membrane and into the soy sauce. this causes the egg to shrivel up due to a lack of water.

Big Money Corp moves a pile of dirt 50.0003 kilometers into the air and exerts a force of 5.0000000000 Newtons. What is the Work in Joules? 

250002 Joules 

400

If ball^TM is at the top of a slide 1.5 meters in height, then what is the Kinetic Energy of ball^TM once it reaches the bottom? Assuming the mass of ball^TM is 1500.0 grams  

22J

500

Assuming pentagon^TM is at the top of triangle^TM which has a hypotonuse of 1.5km and an angle of elevation of 28 degrees. Assuming pentagon^TM has a mass of 1.2 grams and the total efficiency as pentagon^TM rolls down the triangle is 68%, what is the final kinetic energy? 

11J

SUPRISE!!!!!!! (do in order from 100-500)

Hypothectically speaking, if IN MINECRAFT somebody was to bring a completly random object weighing 150.0kg to the roof of the Rockfeller-Hewitt building which is 40.00m in height. What would be the potential energy of the random object?

E_p= 58860 Joules

200

On this continued hypothecial situation IN MINECRAFT, a large quantity of an explosive substance like ethane (C₂H₆) was placed in the afore mentioned random object and ignited, what kind of reaction would it be. Identify and predict the reaction, before balancing the equation.

2C₂H₆ + 3O₂ -> 4CO₂ + 6H₂O

Combustion Reaction

300

Still continuing the COMPLETELY hypothetical situation that takes place IN MINECRAFT. If sphere^TM emerges from the random object for no particular reason and in no particular direction and with 4000.0 J of kinetic energy what would the speed of sphere^TM be if sphere^TM weighs 25.00kg?

V=17.89 m/s

400

Very much still in this 100% hypothetical situation that is entirely within the fictional game known as minecraft, how long would it take for sphere^TM to travel 150 meters? (sphere^TM is still traveling at a velocity of 17.89 m/s)

8.4 seconds

500

Finally, for the last question of this hypothetical situation that is hypothetically happening ONLY within minecraft, if sphere^TM is a large cell with minimal salt inside and lands in saltwater underneath the brooklyn bridge on Friday at midnight.

sphere^TM would shrivel up due to passive transport.
