Metals are found towards the left hand side of the periodic table while Nonmetals are found towards the right hand side of the periodic table.
Non metals are found towards the right hand side of the periodic table. They are not all gaseous at room temperature some nonmetals such as iodine are solid at room temperature.
Nonmetals usually have low melting and boiling points, are brittle, have relatively low density and are not good at thermal and electrical conduction.
Potassium - 39 contains 19 protons, 20 neutrons and 19 electrons. Recall that the number of protons and electrons are equal in a neutral atom.
The following is an accurate matching of the ions;
11 protons, 12 neutrons, 10 electrons = +1 - Na^+
31 protons, 39 neutrons, 28 electrons = +3 - Ga^2+
Group 2, period 5 = +2 - Sr^2+
Silver is a lustrous metal.
- Elements that share the most characteristics are found on the periodic table in the same "horizontal period". False
- If matter has a higher temperature, that means there will be "more" molecular motion. True
- If you cool down a propane tank, there will be "less" pressure in it. True
- If you put a balloon in a freezer, its volume would "increase". False
- If you put the balloon into a chamber where there is half the pressure, its volume will "double". True
- The average atomic mass of Aluminum (Al) is "16.00 amu". False
- Oxygen's atomic number is "8" therefore it has "8" protons in its nucleus. True
- An "electron" has the same mass as a neutron. False
- The nucleus contains "protons and neutrons", virtually all the mass of an atom - True

Answer:
The work done on the hose by the time the hose reaches its relaxed length is 776.16 Joules
Explanation:
The given spring constant of the of the spring, k = 88.0 N/m
The length by which the hose is stretched, x = 4.20 m
For the hose that obeys Hooke's law, and the principle of conservation of energy, the work done by the force from the hose is equal to the potential energy given to the hose
The elastic potential energy, P.E., of a compressed spring is given as follows;
P.E. = 1/2·k·x²
∴ The potential energy given to hose, P.E. = 1/2 × 88.0 N/m × (4.20 m)²
1/2 × 88.0 N/m × (4.20 m)² = 776.16 J
The work done on the hose = The potential energy given to hose, P.E. = 776.16 J
Answer:
I'm just going to tell you the information you need but not the answer so you can learn from the problem.
Explanation:
So he was at 248 km mark and traveled 99 km to get to the 149km mark. Then he turns around to go back 18 km to the 167 km mark. That is all the information you need to complete the question I recommend drawing it out in your notes.
