As we know that, Winnowing is used when the lighter particles is required to remove. Hence, in Case 2 the lighter part is removed and the remaining is needed.
Boil the water to get remove the salt and then use filter paper to remove the microorganisms
Answer:
optical axis also called: central axis or principal axis
Explanation:
Spherical mirrors can be concave or convex. Every day we find them in our homes: Christmas balls, casseroles, spoons. If you experiment with them you will notice that the image they reflect does not have the same characteristics as in flat mirrors. In reality, these characteristics depend, among other questions, on the type of mirror and the distance at which the object is located.
Main elements of a spherical mirror:
- Radius of curvature: is the radius of the sphere to which it belongs.
- Mirror vertex: it is the cap pole, it is located at the point of contact between the main optical axis and the mirror.
- <u>Main optical axis</u>: is the line determined by the vertex or pole and the center of the curvature.
Answer:
hydropower
Explanation:
hydroelectric power is a domestic source of energy. This automatically allows each state to produce their own energy without being reliant on international fuel sources. It also won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. This is because it is powered by water.
I hope this helped. sorry it took so long. I was trying to get the right resources 4 you
Answer:
Zero
Explanation:
Since momentum is a product of mass and velocity of an object, in this case when the object stops its final velocity is zero hence despite the magnitude of its mass, multiplied by zero the final momentum is equivalent to zero. However, in case after experiencing momentum its velocity reduces but doesn’t come to a rest, the momentum will have a value. For this question, the first case applies hence momentum value is zero.
