Answer:

The friction force is what counteracts the movement of the block as it slides down the ramp.

Explanation:

When a forward force is applied, the block moves horizontally along the ramp or floor. The force opposing this movement is known as friction. When stationary, static friction acts on the block preventing movement, but once the block starts moving, static friction is replaced by kinetic friction, which resists the block’s motion and slows it down.

Answer:

A growth rate of 1.6%

It takes approximately 43.75 years to double.

Explanation:

Calculating the growth rate: 40 - 24 = 1616/1000 = 0.016 x 100 gives us a 1.6% growth rate.

Calculating doubling time: 70/1.6 equals roughly 43.75 years.

in the following poem by gregory pardlo (published in 2007), the speaker describes watching children playing double dutch—a vers
Fittoniya [148]

Hello. You overlooked including the poem related to the inquiry. The poem reads:

"The girls turning double-dutch

bob weave like boxers pulling

punches, shadowing each other,

sparring across the slack cord

casting parabolas in the air. They

whip quick as an infant's pulse

and the jumper, before she

enters the winking, nods in time

as if she has a notion to share,

waiting her chance to speak. But she's

anticipating the upbeat

like a bandleader counting off

the tune they are about to swing into.

The jumper stair-steps into mid-air

as if she's jumping rope in low-gravity,

training for a lunar mission. Airborne a moment

long enough to fit a second thought in,

she looks caught in the mouth bones of a fish

as she flutter-floats into motion

like a figure in a stack of time-lapse photos

thumbed alive. Once inside,

the bells tied to her shoestrings rouse the gods

who've lain in the dust since the Dutch

acquired Manhattan. How she dances

patterns like a dust-heavy bee retracing

its travels in scale before the hive. How

the whole stunning contraption of girl and rope

slaps and scoops like a paddle boat.

Her misted skin arranges the light

with each adjustment and flex. Now heather-

hued, now sheen, light listing on the fulcrum

of a wrist and the bare jutted joints of elbow

and knee, and the faceted surfaces of muscle,

surfaces fracturing and reforming

like a sun-tickled sleeve of running water.

She makes jewelry of herself and garlands

the ground with shadows."

Answer and Explanation:

Similes and metaphors serve as literary devices that enhance and personalize the narrative in a poetic manner through analogies. A simile draws comparisons between unrelated elements to create novel interpretations, while a metaphor links disparate items with a shared trait.

The author likens the girls' rope activities to abstract and complex actions that require great precision, strength, and concentration.

These figures of speech appear in lines such as:

"The girls turning double-dutch

bob weave like boxers pulling

punches, shadowing each other,

sparring across the slack cord

casting parabolas in the air. They

whip quick as an infant's pulse

and the jumper, before she

enters the winking, nods in time

as if she has a notion to share,

waiting her chance to speak. But she's

anticipating the upbeat

like a bandleader counting off

the tune they are about to swing into."
