A
More concentrated means more collisions per unit volume, and as the volume stays the same and only concentration changes, the there are more collisions
Answer:
lipids are insoluble in water which is why lipids are often found in biological membranes and other waterproof coverings.
P (gravitational force) = m (mass) x g
<=> P = 0.05 x 10
<=> P = 0.5N
We can't tell without more information. We know it will be higher than 40 and lower than 75, but we don't know exactly where it will settle. In order to work that out, we would need to know the volumes of the water and the cube, and WHAT metal the cube is made of.
