Which of the following is metamorphic rock?
granite |
|
coal |
|
obsidian |
|
marble |
The Earth's rocks fall into three categories based on how they're formed. Igneous rock (granite, basalt, obsidian) is formed from the hardening of molten rock (lava), sedimentary rock (shale, sandstone, coal) is formed by the gradual despositing and cementing of rock and other debris, and metamorphic rock (marble, slate, quartzite) which is formed when existing rock is altered though pressure, temperature, or chemical processes.
Which of the following is the formula for work?
\(W = {{F}\over{d}}\) |
|
\(W = \vec{F}\vec{d}\) |
|
\(W = {F}{d}\) |
|
\(W = {\vec{F} \over \vec{d} }\) |
Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meter (Nm), work is calculated by multiplying force times displacement: \(W = \vec{F}\vec{d}\)
