Sally and Juan’s science teacher has directed the class to build a paper airplane. The challenge is to build an airplane that fl

ies the farthest distance. The students have two days to design and test their planes. The assignment will end with a “fly-off”. Sally and Juan built their first plane. Whenever they tested the plane, it would take a nose dive into the floor. They changed the design by reshaping the nose of the plane and adding some weight to the tail. The plane flew, but did not get very far. Next they tried to change the way they threw the plane. After many tries, their plane flew an average distance of 35 meters. Sally and Juan's trial and error airplane design could be described as ___________________ in the technological design process.
A) evaluating a solution
B) identifying a problem
C) communicating results
D) implementing a design

Evaluating a solution

Answer:

A) evaluating a solution

Explanation:

When we try to produce a technological project many problems and difficulties can occur. These problems can hamper the success of the project and turn all dedication into failure. For this reason, it is important for researchers to be quick to identify problems and solve them.

An example of this can be seen in the question above, where Sally and Juan are trying to solve the problem of their planes. They do not know what is causing the problem and are therefore evaluating a solution, in order to continue the project.

What is the minimum work needed to push a 920-kg car 310 m up along a 6.5 ∘incline? Ignore friction.Express your answer using tw
AVprozaik [17]

Answer:

2800000J

Explanation:

Parameters given:

Mass = 920kg, weight = 920 * 9.8 = 9016N

Distance = 310m

Angle of inclination = 6.5°

Work done is given as :

W = F*d*cosA

Where A = angle of inclination

W = (9016 * 310 * cos6.5)

W = 2776993.59J

In 2 significant figures, W = 2800000J
