Answer:
a variable (often denoted by x ) whose variation does not depend on that of another.
Explanation:
Answer:
See below.
Explanation:
I'll do the second row for you the other 2 are done in exactly te same way.
B. Area of 1 side of cube = 2*2 = 4.
Surface area = 4*6 = 24
Volume = 2*2*2 = 8.
Surface area / volume = 24/8 = 3.
Ratio of Suface Area to Volume = 24 : 8 = 3 : 1. (divide both by 8)
Answer:
The following must be true for diffusion of a solute to occur across a partition that separates two compartments
The partition is semi permeable
There is concentration gradient across the partition
The process is known as Osmosis
Explanation:
Diffusion is the migration of particles of a substance, liquid or gas, from a region of high concentration to a region of lower concentration and it only occurs where there is a concentration gradient for example spraying a perfume at a corner of a room, the spray sent spreads across the room as there is a concentration gradient
Osmosis is the movement or diffusion of solvent molecules across a semi permeable membrane from a region of low solute concentration to a region of high solute concentration to create a balanced concentration of solute on both sides of the compartment.
Answer:
3 and 1
Explanation:
All others are a physical change
Answer is: velocity of the bowling ball is 6.19 m/s.
Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.
m(ball) = 35.2 kg; mass of a bowling ball.
p(ball) = 218 kg·m/s; momentum of a ball.
v(ball) = p(ball) ÷ m(ball).
v(ball) = 218 kg·m/s ÷ 35.2 kg.
v(ball) = 6.19 m/s; velocity of a bowling ball.
