Answer from: judyandaub1

Yes, depending on the context.

Explanation:

If the more massive object is located in an environment that either provides an upward force or has less downward acceleration, then it may exert less force in the downward direction (weigh less) than an object with less mass.

Examples:

1. a 110 kg object weighed under water may show less weight than a 100 kg object weighed in air—particularly if it is much less dense.*

2. a man of mass 80 kg weighed on Earth's moon will definitely show less weight than a 100 kg man weighed on Earth.

* Actually, density has an effect on weight anytime the weighing is done in a medium other than a vacuum. (This is a potential source of error when trying to calibrate scales to very high accuracy.) When weighing is done in water, for example, an object of sufficiently low density will float, so show no weight at all.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic
