Answer:

899752.13598 N

Explanation:

p = Pressure on the plate = 7.16\times 10^4\ Pa

A = Area = \pi r^2=\pi 2^2=\pi 4

F = Force on the region

When force is divided by area we get pressure

p=\frac{F}{A}\\\Rightarrow F=p\times A\\\Rightarrow F=7.16\times 10^4\times \pi 4\\\Rightarrow F=899752.13598\ N

Force is exerted by the atmosphere on a disk-shaped region is 899752.13598 N

Answer:

The maximum height will be 7408.8 meters

Explanation:

final velocity = initial velocity + acceleration × time  

final velocity = 0 m/s + 58.8 m/s^2 ×6 s  

Final velocity = 352.8 m/s  

final velocity ^2 = initial velocity ^2 + 2 × acceleration × displacement  

(352.8)^2 = (0)^2 + 2×58.8 ×displacement  

Solving for displacement,

height = 1058.4 meters.  

After this, the rocket is in free fall, we can use the same equation.  

final velocity ^2 = initial velocity ^2 + 2 ×acceleration×displacement  

final velocity = 0  

0^2 = 352.8^2 + 2×(-9.8)×displacement  

displacement = 6350.4 meters  

the maximum height will be 7408.8 meters

Correct answer choice for question 1 is:


A) Figurative language


Explanation:


Figurative language uses terms of speech to be more powerful, effective, and impactful. Characters of speech such as metaphors, similes, and implications go away the usual meanings of the words to give users new acumens. On the other hand, alliterations, imageries, or echoes are symbolic tools that review the minds of the users. Figurative language can perform in various forms with the use of various literary and eloquent articles.


Correct answer choice for question 2 is :


D) Words that trigger the imagination to remember by appealing to the five senses


Explanation:


Imagery, in a literary text, is an author's use of rich and detailed language to add intensity to their work. It advances to human senses to increase the reader's knowledge of the work. Powerful kinds of comparison join all of the senses. There are seven main kinds of imagery, each resembling a sense, feeling, action, or reaction. Olfactory imagery concerns, scents, or the sense of smell. Gustatory imagery concerns tastes or the sense of taste. Tactile imagery concerns physical forms or the feeling of touch.
