Answer:
HARDNESS
Explanation:
One key physical difference between transition metals and poor metals is their "" Hardness"" which is
the ability of a material to resist deformation. The test for hardness can be determined by a standard test which is the measurement of surface resistance to indentation. hardness tests are defined the shape and also type of indent.
The poor metals are also referred to as post transition metals. They are elements that are found at the right of the transition metals,they are located in the p-block,Their properties is as a result of their low melting and boiling point compare to other metals.They have high electronegativity and conductivity but softer texture compare to other metals.They are very soft more than the transition metals, but they cannot be cannot be classified as metalloids.
Poor metals includes elements in the periodic table such as; aluminium, gallium, indium, thallium, tin, lead, bismuth, and polonium.
Answer:
INTENSITY, TOWARD THE SUN, 45 J
Explanation:
Answer:
A 26m
Explanation:
firstly the answer will not be part c as distance unit will be meters (m)
next, substitute the values of a and t as shown
the answer rounded off to 2 significant figures will be hence 26m
A wave with a greater amplitude carries more energy to wherever it goes.
Answer:
There are about six to seven million cones in a human eye and are most concentrated towards the macula. Cones are less sensitive to light than the rod cells in the retina (which support vision at low light levels), but allow the perception of color.
