Answer:
Explanation:
Your numbers seem wonky, so I'll just assume that the initial displacement is a distance A (Amplitude) from the equilibrium position. Spring constant = k
Initial potential energy is
PE = ½kA²
As potential energy and kinetic energy are constantly exchanging in SHM,
the position x where half of the original spring potential exists is found where
½kx² = ½(½kA²)
x² = ½A²
x = (√0.5)A
x ≈ 0.707A
just plug in your actual starting position A
With A = 5.2 cm
x = 3.67695... 3.7 cm

headlamp glass is a borosilicate glass by gravity feed
Answer:
The time required by the impulse to travel from foot to brain equals 0.019 seconds
Explanation:
For uniform motion the distance, speed, time are related by the equation
In our case since the person is 1.90 meters tall so the nerve impulse will have to cover a distance of 1.90 meters at a speed of 100 m/s.
Hence the time required for the impulse to travel from foot to the brain can be calculated as
Comets are cosmic snowballs of frozen gasses, rock and dust that orbit the sun. When frozen, they are the size of a small town. When a comet's orbit brings it close to the sun, it heats up and spews dust and gasses that form a tail that stretches away from the sun fr millions of miles. There are probably billions of comets orbiting our sun in the Kuiper Belt and even more distant Oort Cloud. Comets have right for its name and had best to orbit the sun in the Kuiper Belt.
I can think of two reasons:
1). EVERY transmitted radio signal is transmitted as
a divergent beam. We don't have the technology to
transmit it as a perfectly parallel beam.
That's a good thing, because ...
2). If it were a perfect pencil-thin parallel beam, then
it would be practically impossible to keep it perfectly
aimed at the satellite.
