A student wants to know if the effect of gravity is the same on all objects. She follows these steps: 1. Drop a 5-gram ball, a 10-gram ball, and a 12-gram ball from a height of 10 meters.

2 Record how long it takes for each object to hit the ground

3: ?
Which step should be next?

Choose new balls

Measure the mass of the balls again

Drop the balls from a different height

Perform a second trial

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
