... In a laboratory experiment, you wish to determine the initial speed of a dart just after it leaves a dart gun. The dart, of mass m, is fired with the gun very close to a wooden block of mass M 0, which hangs from a cord of length l and negligible mass, as shown above. Assume the size of the block is ...

Is it possible to do work on an object that remains at rest?
... Gravitational PE is mgh, where height h is measured relative to some arbitrary reference level where PE = 0. For example, a book on a table has positive PE if the zero reference level is chosen to be the floor. However, if the ceiling is the zero level, then the book has negative PE on the table. It ...

... When a 3.88 g sample of solid ammonium nitrate disolves in 60.0 g of water in a coffee cup calorimeter, the temperature drops from 23.0 °C to 18.4 °C. (a) Calculate H (in kJ/mol ammonium nitrate) for the solution process. Assume that the specific heat is constant and = 4.184 J/g°C. (b) Is this proc ...

The negative sign in (7-13) means that the spring force always directed oppositely to the direction of displacement. This is why spring force ...

The minimum energy necessary for an alpha particle to escape from the nucleus can then be found by evaluating the potential at its local maximum, r = R0 . This minimum energy is high enough that we should, in theory, ...

... well. However, P b214 has only half-decays, and Bi214 and P o214 are rate-limited by lead. Thus, these initial conditions can be described as an activity vector (A0 0 0 A20 A20 A20 ) for some initial activity A0 . We reduce the activity to one comparable with the number of P o214 counts, and plot th ...
