What is Relationship: Definition and 1000 Discussions

An intimate relationship is an interpersonal relationship that involves physical or emotional intimacy. Although an intimate relationship is commonly a sexual relationship, it may also be a non-sexual relationship.
Emotional intimacy involves feelings of liking or loving one or more people, and may result in physical intimacy. Physical intimacy is characterized by romantic love, sexual activity, or other passionate attachment. These relationships play a central role in the overall human experience. Humans have a general desire to belong and to love, which is usually satisfied within an intimate relationship. Such relationships allow a social network for people to form strong emotional attachments.

    Relationship Between Velocities of Two Runners

    Homework Statement Reginald is out for a morning jog, and during the course of his run on a straight track, he has a velocity that depends upon time as shown in the figure below. That is, he begins at rest, and ends at rest, peaking at a maximum velocity Vmax at an arbitrary time tmax. A second...

    Relationship Between Bicycle Tire Pressure and Speed

    Hi, I have been tasked with finding a way to relate a bicycle tire's inflation pressure to its speed in traveling 160 meters. Data was given showing that as the pressure increased from 70 to 90 psi, the speed increased marginally. No equations were given. I think that it may have to do with...

    Crossed polarizers and F-Stop relationship

    This is not homework. I understand that cross-polarizing (using 2 polarizing filters) will reduce the transmitted light intensity "I" to ##cos^2{\theta}##. This is well understood.

    Relationship between friction and weight

    So I know that weight correlates with friction, as in more weight of an object means that it will experience more friction. However, what is not clear to me is why this occurs on a molecular level. Thanks for the help

    Relationship between resistance and heat

    Alloys have higher resistivity than pure metals. In real life, our voltage source ,i.e. battery, is constant. Using the formula H=V^2/R, we get that resistance is inversely proportional to heat. Alloys, in that case, will produce less heat as their resitivities are low, so are their resistances.
