Home >All Categories > Science & Mathematics >Physics >Open Question Britney Member since:February 23, 2011Total points:92 (Level 1)What are the conditions of a body which is acted upon by parallel co-planar forces?Answer Question

by dev Member since:December 25, 2010Total points:336 (Level 2)There are two conditions
(1) The vector sum of all the forces acting on the object must be zero.
Mathematically,?F vector=0. This condition ensures that the object remains at a
particular location and does not moving linearly (unless it is already in motion
with a constant uniform velocity).
(2) The algebraic sum of the torques about any axis of the object must be zero.
Mathematically ? torque vector=0, . This condition requires that the sum of the
counterclockwise torques must be equal to the sum of the clockwise torques
about the axis of rotation. Therefore when the net torque is zero, the object
remains in rotational equilibrium. This implies that either the object does not
rotate (rotational static equilibrium) or that it rotates with a constant angular
velocity (dynamic equilibrium)

(1)Hello, this is my question. how many moles of oxygen gas (O2) are needed to produce 36.04 grams of water (H2O) when reacting with excess ethane in the equation 2C2H6 + 7O2 5CO2 + 6H2O?
A. 19.0 moles of oxygen (O2)
B. 14.0 moles of oxygen (O2)
C. 2.3 moles of oxygen (O2)
D. 1.2 moles of oxygen (O2)

How many moles of water would be produced from the reaction of 3.25 moles of hydrochloric acid racting with excess calcium hydroxide?
help me please!

so i need this on an assignment for school and i wasn't really listening when he explained it. I just want the 3 components in paragraph form. :P oh and dont add to many sophisticated words because im copy and pasting.

heres the question word for word: describe the 3 major components necessary to help you understand the relationship between a graph, equation and a table of values.
