Answer:
A) 200 j
B) 0 J
C) -100 J
D) -300 J
Explanation:
We know that change in potential energy is given as
where, mg is weight
yf and yi final and initial position
mg = 10 N
yf = 0 m
yi = 20 m
B) mg = 10 N
yf = 20 m
yi = 20 m
c) before fall from the drone
U = mgh
h = yf - yi = 20 - 30 = -10 m
D) point has 0 potential energy
mg = 10 N
h = yf -yi = 0 -30 = - 30 m
Answer:
from outside of the bottle to inside is by conduction and bottom to tha top of the water is by convection
Move with constant speed or accelerate and will determine direction
I’m pretty sure you’re correct
Solute, solvent.
Solute is what is dissolved in the solvent. Since there is less oxygen and more nitrogen, the oxygen is the solute and the nitrogen the solvent. Solution is not included in the answer because the air is the solution (the combination of the solutes and solvent).
