Answer:
Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
Explanation:
Answer:
Object B has greater density
desity A=20/10=2 g cm^-3 . density B=50/10=5 g cm^-3
the object that has greater mass has the greater density because the volume of the those two objects are same
When lost fluid is not replaced adequately, dehydration can result.
Answer:
Hydrofluorocarbons (HFCs) are man-made organic compounds that contain fluorine and hydrogen atoms, and are the most common type of organofluorine compounds. Most are gases at room temperature and pressure.
Answer:
108.8 m /s
θ = 21°
Explanation:
Centripetal acceleration = ω² R
=( 13 )² x .602
= 101.74 m/s²
tangential acceleration a_t = angular acceleration x R
= 64.1 x .602
= 38.58 m /s²
Total acceleration R
R² = ( 101.74 )² + ( 38.58 )²
R = 108.8 m /s
angle required be θ
Tanθ = tangential accn / radial accn
= 38.58 / 101.74
θ = 21°
