Find the length of the stock needed to create the shape as shown the right. A stock with a thickness of 4 centimeters can be divided into three parts from left to right: a vertical part of length 20 centimeters; a curved surface extending outwards that is one-quarter of a full circle of radius 8 centimeters; horizontal part of length 25 centimeters. The length of the stock needed to create the shape is approximately nothing ▼ cm squared . cm. (Simplify your answer. Round to the nearest tenth as needed.)

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
