<em>A</em> - <em>B</em> = (10<em>i</em> - 2<em>j</em> - 4<em>k</em>) - (<em>i</em> + 7<em>j</em> - <em>k</em>)
<em>A</em> - <em>B</em> = 9<em>i</em> - 9<em>j</em> - 3<em>k</em>
|<em>A</em> - <em>B</em>| = √(9² + (-9)² + (-3)²) = √189 = 3√19
Answer:
If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes.
Explanation:
Hope i explained that clearly... :)
Answer:
the speed in -y
Explanation:
For this exercise we must use the right hand rule. The motion of a positive charge is given by.
Thumb points in the direction of speed
fingers extended in the direction of the magnetic field, + z axis
the palm in the direction of the force, as the charge is negative in the opposite direction of the force, axis + x
therefore the thumb is in the direction - y
the speed in -y
Answer:
<u><em>hydrostatic</em></u><em>; </em><u><em>colloid osmotic</em></u>
Explanation:
Hydrostatic pressure, <em>due to the force of gravity, is the pressure exerted by a liquid at an equilibrium point inside the fluid. </em>
Due to the increasing weight of the water exerting downward force from above, hydrostatic pressure increases in proportion to the distance measured from the surface.
Oncotic pressure, or colloid osmotic pressure, i<em>s a type of protein-induced osmotic pressure, especially albumin, in the plasma (blood / liquid) of a blood vessel which displaces water molecules, causing a relative molecular water deficit with water molecules moving back into the circulatory system within the capillary end of the lower venous pressure.</em>
Answer:
because circle D mixed all the four colors together(blue, pink, grey). Although circle C has blue and gray molecules there aren't any pink molecules.
