Answer:
Frequency
Explanation:
It’s kinda self-explanatory but bascially speed=wavelength times frequency
Answer:
The correct options are;
C. Divergent plate boundary
D. Normal faults
Explanation:
Tensile stress tends to pull objects part by acting axially upon the object to pull the object on a cross section perpendicular to the objects cross-section
The most common stress in convergent plate boundaries is compression stress
The most common stress in divergent plate boundaries is tensile stress
In the presence of tensile stress, normal faults results in the raising of mountains due to their enormous forces
Therefore, the features of Earth's crust involving tension are divergent plate boundary and normal faults.
Answer:
The general electronic configuration of the element present in the 13th group of the periodic table is . Therefore, the number of valence electrons of the group 13this 3. Also, the metalloid element which is present in group 13th is boron. Hence the metalloid which has 3 valance electrons is boron.
Explanation:
Llowing certain substances to pass through it but not others, especially allowing the passage of a solvent but not of certain solutes.
