Is it possible to have a magnet with only one pole? Explain.
Answer:
no.
Explanation:
The reason this has
never happened is due to the source of magnetic fields: moving electric
charges. When electric charges (e.g. electrons) move in circles, they
produce a magnetic field. In a piece of iron, it is very easy to line up
these circles, getting all the little magnets to work together as one big
magnet.
For each of these circles, one side is the north pole and one side is the
south pole. Since each circle has two sides, each circle has a north and a
south pole. Even the smallest possible magnets (spinning electrons) have a
north and a south pole.
what is the relationship between the distance from an object and the strength of its gravity?
Answer:
the separation distance will weaken the gravitational force get weaker
Explanation:
separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

Color is everywhere in nature. The arrows in the image model the wavelengths of visible light. Compare how the incoming colors of light behave when they encounter the kittens black fur, it’s white fur, the green grass, and the yellow dandelion
Answer:
The black color absorbs all colors of light, the white reflects all colors of light, the yellow-orange flowers only reflect yellow and orange light, and the green grass only reflects green light. It is because they reflect certain colors of light that these objects display certain colors.
Explanation:
A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns.
a. gene modification
b. artificial selection
A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns. This is called as gene modification.
What is gene modification?Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology.
Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA.
For example, cornstarch can be made with GMO corn and sugar can be made with GMO sugar beets. Corn: Corn is the most commonly grown crop in the United States, and most of it is GMO. Most GMO corn is created to resist insect pests or tolerate herbicides.
Therefore, A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns. This is called as gene modification.
