a person walks 750m due north then 250 m due east of the entire walk takes 12 min find the person average velocity​

Answers

Answer:

v = 1.098 m/s

Explanation:

Given that,

A person walks 750m due north then 250 m due east of the entire walk takes 12 min.

We need to find the average velocity of the person.

Displacement,

[tex]d=\sqrt{750^2+250^2} \\\\d=790.56\ m[/tex]

Average velocity = displacement/time

[tex]v=\dfrac{790.56\ m}{12\times 60\ s}\\\\v=1.098\ m/s[/tex]

So, the average velocity of the person is 1.098 m/s.

Two cars approach each other from opposite directions each
with a velocity of 54 km/h. One of the cars emits a note of frequency 480 Hz. What will be the approximate frequency
heard in the other car before they cross each other?

Answers

Answer:524 Hz

Explanation:

Approximate frequency, heard in other car, when two car approaches each other, before they cross each other is 524 Hz.

What is frequency?

Frequency of wave is the number of waves, which is passed thorough a particular point at a unit time.

For the two cars approaching each other the Doppler formula to find the frequency of second car is given as,

[tex]f_2=\dfrac{V_s+V_2}{V_s-V_1}f_1[/tex]

Here, [tex]V_s[/tex] is the speed of the sound.

Two cars approach each other from opposite directions.The velocity of car one is 54 km/h and the velocity of the car two is also 54 km/h.

Convert the unit of velocity of the car as,

[tex]\rm 54km/s=54\times\dfrac{5}{18}m/s\\\rm 54km/s=15m/s[/tex]

As we know that the speed of the sound is 340 m/s and one of the cars emits a note of frequency 480 Hz.

Thus, putting the values in the above formula to find out the frequency heard in the other car before they cross each other as,

[tex]f_2=\dfrac{340+15}{340-15}480\\f_2=524.3\rm Hz[/tex]


The approximate frequency heard in the other car before they cross each other is 524 Hz.

Can someone explain the meaning of this quote: "It wasnt only wickedness and scheming that made people unhappy, it was confusion and misunderstanding; above all, it was the failure to grasp the simple truth that other people are as real as you. And only in a story could you enter these different minds and show how they had an equal value. That was the only moral a story need have." -Atonement Ian Mcewan When Gregor Samsa woke up one morning from unsettling dreams, he found himself changed in his bed into a monstrous vermin. He was lying on his back as hard as armor plate, and when he lifted his head a little, he saw his vaulted brown belly, sectioned by arch-shaped ribs, to whose dome the cover, about to slide off completely, could barely cling. His many legs, pitifully thin compared with the size of the rest of him, were waving helplessly before his eyes.Whats happened to me? he thought. It was no dream. His room, a regular human room, only a little on the small side, lay quiet between the four familiar walls. Over the table, on which an unpacked line of fabric samples was all spread out--Samsa was a traveling salesman--hung the picture which he had recently cut out of a glossy magazine and lodged in a pretty gilt frame. It showed a lady done up in a fur hat and a fur boa, sitting upright and raising up against the viewer a heavy fur muff in which her whole forearm had disappeared.Gregors eyes then turned to the window, and the overcast weather--he could hear raindrops hitting against the metal window ledge--completely depressed him. How about going back to sleep for a few minutes and forgetting all this nonsense, he thought, but that was completely impracticable since he was used to sleeping on his right side and in his present state could not get into that position. No matter how hard he threw himself onto his right side, he always rocked onto his back again. He must have tried it a hundred times, closing his eyes so as not to have to see his squirming legs, and stopped only when he began to feel a slight, dull pain in his side, which he had never felt before.Evaluate the excerpt from Metamorphosis.
