Question:
Diffusion is the movement of particles from high to low concentration. True or False
Answer:
True.
Explanation:
Diffusion is a process that allows the movement of substance or particles in and out of cells through a semipermeable membrane.
Diffusion is a process that allows the spread or movement of particles from the region of higher concentration to a region of lower concentration through a semipermeable membrane.
Diffusion only occurs in gases and solution but not in solids, it also occurs only where particles can move freely.
Note: When particles move from the region of higher concentration to a lower concentration, it gives room for even, uniform and random distribution of particles.
Answer:
The force parallel to the horizontal is 26.24 N
Explanation:
She pulls on the leash with a force F = 30 N, this force, since its at an angle of 29° (i will cal this angle 
), it has a force component on x (the horizontal, i will call this force 
) and a force component on y (the vertical, i will call this 
).
This can be seen in the attached picture.
Since we are asked about the force parallel to the horizontal, we need to find the component of the force , since is the adjacent angle, we need to use cosine:
since 
and 
The force parallel to the horizontal is 26.24 N
Answer:
Potential, Kinetic and Chemical energy.
Explanation:
btw, congratulations for turning into an expert.
Answer:
Efficiency = StartFraction T Subscript h Baseline minus T Subscript C Baseline over T Subscript h Baseline EndFraction times 100. Efficiency equals T Subscript c Baseline minus T Subscript h Baseline over T Subscript h Baseline all times 100.
They have pure elements or a verity of compounds inside.
