<span>208.3 meters The product of the wavelength multiplied by the frequency will equal the speed of light which is 299792458 m/s. Simple algebra will tell you that you can divide the speed of light by the frequency to get the wavelength. So 224997958 m/s / 1080000 1/s = 208.3314426 m Rounding to 4 significant digits gives you 208.3 meters.</span>

A 65 kg cart travels at a constant speed of 4.6 m/s. What is its kinetic energy?
Talja [164]

Answer:

Explanation:

mass (m) = 65 kg

velocity (v) = 4.6 m/s

Kinetic energy (KE)

= 1/2 * m * v²

= 1/2 * 65 * 4.6²

=  687.7 J

hope it helps :)

The literary movement with which Wilde is most closely associated is Select one: a. romanticism b. existentialism c. Art for art
jeyben [28]

Answer:

Correct answer is ''c'' Art for art's Sake

Explanation:

Wilde wrote in the literary movement called Aestheticism during the late nineteenth century. Contrary to popular belief, Wilde did not create the literary movement, but played a role as a leader who promoted the movement. While Wilde was a college student the works of Algernon Charles Swinburne and Edgar Allan Poe influenced his own writing style. Also, the English essayist Walter Pater helped to form Wilde's humanistic aesthetics.

The philosophical foundations of Aestheticism come from Immanuel Kant. He formulated the idea of "art for art's sake". He believed that art was to be enjoyed for its own beauty regardless of social or moral concerns.

A 150 g baseball pitched at a speed of 45 m/s is hit straight back to the pitcher at a speed of 60 m/s. What is the magnitude of
abruzzese [7]

Answer:

The average force is 1578.94 N.

Explanation:

Given that,

Mass of baseball = 150 g

Speed = 45 m/s

Speed of pitcher = 60 m/s

Time = 9.5 ms

We need to calculate the average force

Using formula of impulse

J=\Delta p

J=m\Delta v...(I)

J=F\Delta t....(II)

From equation (I) and (II)

F=\dfrac{m(v_{f}-v_{i})}{\Delta t}

Where, m = mass of baseball

v_{f} = final velocity

v_{i} = Initial velocity

\Delta t = time

Put the value into the formula

F=\dfrac{150\times10^{-3}\times(60-(-40))}{9.5\times10^{-3}}

F=1578.94\ N

Hence, The average force is 1578.94 N.
