Explanation:
Below is an attachment containing the solution.
Answer:
180^2 + 390^2 = force ^2 (Pythagoras) root of force^2 = 429.5N approx resultant force Acceleration = Force/Mass 429.5/270 = 1.5907 ms^-2 in a Southwesterly direction.
Explanation:
It's a Angstrom Exponent. You can research that term from here.
Answer:

Explanation:
As we know by the formula of elasticity that

now we have


Area = 15.2 mm x 19.1 mm

now we also know that force is given as

here we have
stress = Force / Area


now from above formula we have



The answer is; metamorphic
Occurs when igneous and sedimentary rocks are subjected to extreme temperatures and pressure such that their chemical composition changes. Examples of metamorphic rocks are; marble (that metamorphoses from limestone rock), quartzite (from sandstone). Other types of metamorphic rock include gneiss and schist.
