30 kg m/s
momentum = mass x velocity = 10 x 3 m/s =30 kg m/s
Answer:
Hydrogen bonding
Explanation:
As a rule of thumb, "likes dissolve like", meaning polar solutes dissolve in polar solvents and nonpolar solutes in nonpolar solvents. In this case, water is polar (<em>dipolar moment</em> = 1.85 Debye) dissolves methanol which is also polar (<em>dipolar moment</em> = 1.69 Debye). Besides being dipoles, both molecules have atoms of Hydrogen with a covalent bond to more electronegative atoms of Oxygen. When this happens, stronger dipole-dipole interactions appear known as Hydrogen bonding. There is an electrostatic attraction between H (positive charge density) and O (negative charge density).
Answer:
Atoms are neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.

Answer:
They break down the plants and animals they eat.
Explanation:
Consumers are the organisms which feed on plants and animals for obtaining energy. The carbon which is present in plant body in the form of glucose which is made in the process of photosynthesis. When these plants are eaten by consumers, the carbon which present in plants are transferred into the animal's body. This carbon is removed from the body of consumer in the process of cellular respiration and again goes to the atmosphere.
