The molecules of 1024 is 6382 and with the amount of 1540
Answer: C.
whether it can be separated into simpler substances through physical separation techniques
Explanation:
A heterogeneous mixture is colloidal if
- Particles cannot be seen with a naked eye.
- Particles can pass through filter paper
- It doesn't undergo sedimentation.
A heterogeneous mixture is suspension if
- Particles can be seen with a naked eye.
- Particles cannot pass through filter paper
- It undergoes sedimentation.
So, the criteria are responsible for deciding whether a heterogeneous mixture is a colloid or a suspension is "whether it can be separated into simpler substances through physical separation techniques".
So, the correct answer is "c".
The answer is D. Velocity has a direction and a magnitude, so to have a constant velocity, none of them should be changing. A seems right at first, but when the cat climbs up a tree, it's changing directions. B says the cat slows down which means there's a change in velocity and acceleration is present. C says that the cat's running around in circles so it's constantly changing directions. D is the only right one because the magnitude of velocity (speed) is 0 and not changing neither is the direction.
Hope this makes sense!
As a seed plant germinate, the new plant is called an seedling after the leaves first open , seedling can be defined as a young plant developing out of a plant embryo from a seed. Seedling development starts with germination of the seed.
