You push an object initially at rest across a frictionless floor

Answers

Answer 1

 t = t₀ / 2

Explanation:

In this exercise we must use Newton's second law

         F = m a

         a = F / m

now we can use kinematics

 as in object part of rest (v₀ = 0)

       v =a t₀

       t₀ = v / a

these results are with the first experiment

now repeat the experiment, but F = 2F₀

          a = 2F₀ / m = 2 a₀

         v = 2 a₀ t

         t = v / 2a₀

         t = t₀ / 2

Summary of Photorealism

The name Photorealism (also known as Hyperrealism or Superrealism) was coined in reference to those artists whose work depended heavily on photographs, which they often projected onto canvas allowing images to be replicated with precision and accuracy. The exactness was often aided further by the use of an airbrush, which was originally designed to retouch photographs. The movement came about within the same period and context as Conceptual art, Pop art, and Minimalism and expressed a strong interest in realism in art, over that of idealism and abstraction. Among several male practitioners of Photorealism there is an interest in themes of machinery and objects of industry such as trucks, motorcycles, cars, and even gumball machines, whereas Audrey Flack, the sole female practitioner, infuses her works with greater emotionality and the transience of life. Ultimately, the Photorealists were successful in attracting a wide audience, but they are often overlooked by art historians as an important avant-garde style.

John is standing on top of a 19.6-m tall bridge. off in a distance, he sees a boat approaching the bridge at constant speed. when the boat is 27 m from the bridge, john drops a stone. the stone hits the water 3 m in front of the boat.how fast is the boat traveling?

Answers

If  john drops a stone and the stone hits the water 3 m in front of the boat. The speed of the boat is: 12m/sec.

Speed

First step is to find the time

-19.6 m = -1/2 ×9.8 m/s² × t²

0 = -4.9t²  + 19.6

-19.6  = -4.9t²

t²=  19.6 / 4.9  

t  =√(19.6 / 4.9)

t=√4

t = 2 seconds

Second step is to calculate the speed using this formula

Speed=Distance/Time

Let plug in the formula

Speed=27 - 3/2

Speed=  24/2

Spee= 12m/sec

Inconclusion the speed of the boat is: 12m/sec.

A poll worker analyzing the ages of voters found that and . what is a possible voter age that would give her zx = 1.14? round your answer to the nearest whole number. 59 66 71 90

Answers

Answer:

Option C, 71.

Explanation:

A possible voter age that would give z = 1.14 is 64 years old (rounded to the nearest whole number).

What is standard deviation?

A standard deviation is a measure of how far apart the data is from the mean.

Assuming the question is asking for a possible value of the population mean age, and given that the worker found that the sample mean age is x = 65 and the sample standard deviation is s = 8.

We can calculate the standardized score (z-score) for a given population mean age using the formula:

z = (x - m) / (s / sqrt(n))

Where x is the sample mean age, m is the population mean age, s is the sample standard deviation, and n is the sample size.

To find a possible value of m that would give z = 1.14, we can rearrange the formula and solve for m:

m = x - (z x s / sqrt(n))

Putting in the given values, we get:

m = 65 - (1.14 x 8 / sqrt(100))

m = 65 - 0.91

m = 64

Therefore, a possible voter age that would give z = 1.14 is 64 years old (rounded to the nearest whole number).
