Answer:
osmosis
Explanation:
osmosis is the movement of solvent materials through a semi permeable membrane into a region of solute concentration, therefore water moving through a membrane is an osmotic process.
Answer:
The stress is calculated as
Solution:
As per the question:
Length of the wire, l = 75.2 cm = 0.752 m
Diameter of the circular cross-section, d = 0.560 mm =
Mass of the weight attached, m = 25.2 kg
Elongation in the wire,
Now,
The stress in the wire is given by:
(1)
Now,
Force is due to the weight of the attached weight:
F = mg =
Cross sectional Area, A =
Using these values in eqn (1):
Answer:
statements <em><u>2, 3, 4, and 7</u></em> are true
Explanation:
The friction force between the box and the incline if the box does not slide down the incline will be 0.577
The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction. There are several kinds of friction: Two solid surfaces in touch are opposed to one another's relative lateral motion by dry friction.
Given the box resting on the inclined plane above has a mass of 20kg and the The incline sits at a 30 degree angle
We have to find the friction force between the box and the incline if the box does not slide down the incline
Since the frictional force F₁ must equal or exceed gravitational force F₂ down the incline:
F₁ = F₂
μmgcosΘ = mgsinΘ
μ = (mgsinΘ)/(mgcosΘ)
μ = tanΘ
μ = 0.577
Hence the friction force between the box and the incline if the box does not slide down the incline will be 0.577
