Kerry is explaining to a friend that she will be conducting a descriptive investigation. she wants to know if increasing the size of a parachute affects a skydiver’s time in the air. she plans on having skydivers drop from the same height but with different chute sizes and comparing the data. what is unusual about the description of her scientific investigation? a. descriptive investigations cannot have procedures.
b. this is not a descriptive investigation.
c. this is not a proper scientific question.
d. descriptive investigations cannot have a question.
Thanks for taking the time to read this!

spectral lines lyman is one set

the answer is 3.1 his answer is wrong mines is right

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
