Explanation:
A rigid beam with one end at the origin has a force, F = 7.1 i +-1.8 j +7.8 k N acting on it at a position r = 2.4 i +5.3 j +8.4 k m from its fixed pivot point at the origin, Determine the magnitude of the torque exerted by this force.

Answer:
If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks.
Answer:
Q=cmΔT
Q1(steel)=Q2(water)
c1•m1• (t1-t) = c2•m2• (t-t2)
628•0.1•(80-t) = 4180•0.2• (t-10)
5024-62.8t = 836t -8360
5024+8360=(836+62.8)t
t=14.9°C
Answer:
An object changes position if it moves relative to a reference point. The change in position is determined by the distance and direction of an object's change in position from the starting point (displacement). Direction • Direction is the line, or path along which something is moving, pointing, or aiming.
