указать уравнение гармонических колебаний математического маятника длина которого 2,5 м а амплитуда колебаний 0,1 м.

Ответы

Автор ответа: MrsVaderr

x=x0sinwt, где x0-амплитуда, w-циклическая частота
Её мы найдём из формулы периода колебания мат.маятника:
T=2пи√(l/g)=3,14
w=2пи/T=6,28/3,14=2
Таким образом, уравнение гармонических колебаний в данном случае будет иметь такой вид:
x=0,1sin2t

Task 3. F Read the text. For each question choose the correct answer A, B, C or D.
Like Nothing on Earth!
I couldn't believe my eyes as people in blue space suits floated around on the screen in front of
me. They were laughing and trying to catch objects drifting past them. A voice spoke "Imagine
floating like an astronaut. Experience true weightlessness, just as NASA's astronauts do, aboard
our specially modified Boeing 727 airplane, the Zero Gaircraft!!!The video came to an end and
our instructor switched on the lights before speaking to us. "So are we ready then?" I could never
have imagined what I was about to do! It all started a few months ago when a friend of mine
encouraged me to enter a competition on a local radio station. The winner would get to
experience an 'anti-gravity' flight operated by a company called Zero G. An opportunity like this
is rare as the starting price for a ticket is over #3, 000. The only other way to access such a flight is
to qualify as a student for one of the educational programmes offered. So you can imagine my
surprise when I got a call saying I had won.
The day of the flight finally arrived and it was a bright, cool morning as our small group made our
way to a large airplane hangar. Our instructor was there to greet us and we were each given our
own blue space suits. Next, we sat down to watch an informational video. It explained that we
would experience 'micro gravity' or zero gravity as our plane did a series of steep climbs and
descents. It was during the descents that we would experience zero gravity that would last about
30 seconds and then gravity would suddenly return. Finally, the video demonstrated some safety
techniques such as keeping our feet down or risk landing on our heads. Just before boarding the
plane our instructor recommended not getting caught up with doing flips and turns but instead
trying to enjoy the unique sensation of weightlessness. I would later realize how important his
suggestion really was.
The plane took off and soon we were high above the clouds. Suddenly it was time. "Feet down!"
called out our instructor. Whoosh! My body rose abruptly from the floor and I was floating light
as a feather! I Tried to turn but there was nothing to hold on to. An arm caught my foot and sent
me slowly spinning towards the ceiling. I was hovering effortlessly near the ceiling when all of a
sudden the pilot pulled up and I fell to the floor! This happened another 12 more times during the
flight. I felt like a pinball bouncing around in all directions before crashing to the ground again
On the last time, I remembered what our instructor had said; I just laid back and took in the
amazing sensation of weightlessness.
Before I knew it, we were back on the ground and taking pictures in front of our aircraft. The
of zero gravity is almost impossible to explain. Unlike skydiving and free falling, a person
does not feel the pull of gravity. Nothing i've experienced before can come close to what it's like
to float in anti-gravity, It's something everyone should experience for themselves. I know I'm
glad I did as it was a once in-a-lifetime experience that I'll never forget!
