True or False 9. The number of protons will tell you what element it is. 10. The Atomic Mass - (minus) The Atomic Number tells you the number of protons in an element. 11. If an element is an ion, it has more or less neutrons than usual. 12. Elements in the same vertical column are called Periods. 13. The 3 groups of the periodic table are metals, non-metals, and gases. Help please:))) sorry im not really good with physical science:(

Which type of basaltic lava flow has a fairly smooth

Talia is manufacturing rolls of wire for hanging pictures. she needs a material that is so that it can easily be pulled into wire without breaking.

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
