A Stick a fork into each end of the root vegetable as shown. The forks should be on the same side of the
vegetable, and slightly angled away from each other. Place the forked vegetable on the edge of a box or
thin wall with the forks hanging down. Does the forked vegetable balance in any position? Is there a
position that works better than another? Explain.

Part B.
Consider this question posed at the beginning of the task:
Does Earth's gravitational force field act on objects that aren't touching Earth's surface?
Did the investigation answer the question? Explain whether it gave enough evidence to support the idea
that an invisible gravitational force field exists.

Part C
How might someone dispute the results of your investigation? How might you counter the argument?

Part D
What would improve the investigation design or procedures?

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
