the titanic was 883 feet long and 175 feet tall.
a. if a model is built to have a scale ratio of 1in : 36ft , how long will the model be?
b. if a model is built to have a scale ratio of 1 in : 22 ft , how tall will the model be?
c. if a model is built to have a ratio of 1: 30 , how tall will the model be?

A. 24.53 inches long

B. 7.95 inches tall

C. 5.83 inches tall

Step-by-step explanation:

Original size of the Titanic was 883 feet long and 175 feet tall.

A. Scale ratio of 1 in : 36 ft.

scale ratio of a model =

Now length =

Let the length of the model be l inches

so length = =

             l   =

                 = 24.52777 ≈ 24.53 inches long.

B. Scale ratio of 1 in : 22 ft.

scale ratio of a model =

Let the model will be h inches tall.

so height = =

             h =

                = 7.954545 ≈ 7.95 inches tall

C. Scale ratio of 1 in : 30 ft.

scale ratio of model =

Let the model will be h inches tall.

so height = =

       h       =

                = 5.83 inches tall.

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
