When melting, energy is being absorbed. When freesing, energy is being released.
That's all I know.
Answer:
The forces experienced by the middle particle are attractive, and the net force will remain the same (0) if and only if the distances of the sides particles to the middle particle are the same.
Explanation:
In example 20.3 the forces experienced by the middle particle are repulsive because all the particles are positive, for the case in which the particles on the sides are replaced for negative charge particles the forces experienced by the middle particle are attractive. Regarding the net force, because we don't know the distances we can not give a definitive answer, what we can say is that if the distances from the middle particle to the sides particles are the same the net force is zero for both cases (remain unchanged).
First, convert the given volume in gallons to millliters by the appropriate conversion factors
(13.7 gal) x (3.785 L / 1 gal) x ( 1000 mL / 1) = 51854.5 mL
Multiply this value with the given density to obtain the mass in grams. The operation gives an answer of 38216.7665 g.
Answer:
Answer:
the shoe which having heel of smaller crossection area.
Explanation:
Pressure is defined as the thrust acting per unit area.
Thrust is the force which acts on the surface perpendicularly.
Pressure = force / Area
Its SI unit is Pascal or Newton per square metre.
As both the shoes have same mass, so force is same but the area of crossection is different for both the shoes.
Teh shoe having heel of small crossection area exerts more pressure on another person's feet then the shoe having heel which has more crossection area.
Explanation:
Answer:
Kyra is more precise.
Explanation:
Kyra is more precise as she has included the exact point second it had dissolved whereas Pari just rounded it to the closest number making her write a whole number that was rounded down.
