how can I tell if there are more positive ions in a cell than another with different RMP

yo i need help om physics, specifically on the electricity unit. The charge by induction part is confusing as shit and i don't get what the ground does. 

A ball is rolled up a constant slope. After 3.6s it reaches its maximum displacement of 2.6m and then begins to roll back down. What was the initial velocity of the ball when it started up the slope

what is the difference(s) between autosomes 1-22 and chromosome pair 23

MgO(s)+2HCl(aq) -> MgCl2(aq) + H20(l)

Please explain how I find the enthalpy of this equation?

Chef Potato's body has a cylinder in the middle and two half spheres that make up his bottom and head. He has the two dimensional shape measurements as follows: 20 cm in total length, 5 cm between the end of the cylinder and the top of the top sphere. Reduce Chef1.) Potato by a scale factor of 0.5.2.) Chef Potato needs to be converted from a two dimensional shape to a three dimensional object and then enlarged to 300% of his original size. The three dimensional chef potato is similar in shape to a capsule made of a half sphere at the top, and a half sphere at the bottom and a cylinder in between. Determine the surface area of the enlarged three dimensional chef potato and the scale factor.3.) What are possible dimensions of a box that could be used to deliver the enlarge model of chef potato to store? Justify your answer.

4(d+3) - 3(d-2)=1.2

$60=\sqrt{252d\left(0.72\right)}$60=√252d(0.72)
