How much voltage must be used to accelerate a proton (radius 1.2×10−15m) so that it has sufficient energy to just "touch" a silicon nucleus? a silicon nucleus has a charge of +14e, and its radius is about 3.6×10−15m. assume the potential is that for point charges.

Apossible explanation for a set of facts that can be tested by further investigation is called

Aphysical change is a change in the size, shape,, or stafe of matter true or false

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
