Question

a gardener holds the nozzle of a hose constant at a small angle above the horizon from the nozzle. if the pressure of the water is increased so that the water leaves
o the height of the waters path will increase but the width of the path will rem
the height and width of the waters path will increase.
o the height and width of the waters path will remain the same.
o the width of the waters path will increase but the height will remain the same

question 7
choose the best answer from the options that follow each question.
in the absence of air resistance, the path of a projectile is a(n)
o polygon.
o semicircle.
o parabola.
o arc.

Explanation:

For the first question, increasing the water - pressure increases the initial velocity of the water. The height and range (width) of a projectile's (water in this case) path are both related to the initial velocity. Higher initial velocity leads to greater height and width. For the second question, in the absence of air resistance, the path of a projectile is a parabola because the horizontal motion is a uniform - motion and the vertical motion is a uniformly - accelerated motion under gravity.

Answer:

For the first question: the height and width of the water's path will increase.
For the second question: C. parabola.
