Brisa's kite is flying above a soccer field at the end of 43 m of string. If the angle of elevation to the kite measures 72degree, and Brisa is holding the kite 1.2 m off the ground. How high above the ground is the kite flying? (Round to the nearest meter)

The height the kite is flying above the ground level to the nearest meter is 42m.

Step-by-step explanation:

this is not drown to scale:

  |\

  |  \

x |   \   43m

  |    \

  |___\

         Angle is 72º

sine = opposite / hypotenuse

sin 72 = x / 43

0.9510565 = x / 43

therefore x = 40.9m

Brisa is holding the kite 1.2 m off the ground, we also need to add 1.2 m to our calculated height of the kite. Thus, the answer is  

           40.9 m + 1.2 m = 42.1 m to the nearest meter is 42m.

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
