Answer 1

Answer:

4th answer

Explanation:

The gradient of a distance-time graph gives the speed.

gradient = distance / time = speed

Here, the gradient is a constant till 30s. So it has travelled at a constant speed. It means it had not accelarated till 30s. and has stopped moving at 30s.

Explain what occurs to satellites when they travel too fast and too slow to keep in orbit

Answers

If the satellite goes too slow:

It will crash into it's surrounding things it's orbiting.It would not go forward enough due to pull of gravity.Gravity will pull it back to Earth.The satellite could be knocked or moved closer or farther from the object it is orbiting.

If the satellite goes too fast:

It will eventually fly away.It can go forward soo fast.It would go too fastly that gravity can't retain in an orbit.The satellite's inertia would carry it off into space.

An instructor gives a demonstration in which he makes a standing wave on a long thin slinky. The slinky is 6.0 meters long. If you see 3 loops on the slinky when the instructor shakes the end of the slinky at a rate of 2.50 cycles per second, then the speed (in m/s) of transverse traveling waves on the slinky is

Answers

The characteristics of standing waves allows to find the result for the speed of the wave is:

The speed wave is: v = 10 m / s

The wave is a way of transmitting energy without mass displacement, , in the attachment we can see a diagram of the standing wave.

Each cycle corresponds to half a wavelength, they indicate that the frequency is 2.50 Hz and there are three cycles, so the wavelength is:

L = [tex]n \frac{\lambda}{2}[/tex]

λ = 2L/n

λ = 2 6 /3

λ = 4 m

Wave speed is related to wavelength and frequency

v = λ f

v = 4 2.5

v = 10 m / s

In conclusion, using the characteristics of standing waves we can find the result for the speed of the wave is:

The wave speed is: v = 10 m / s

When these photons are emitted, they travel between two surfaces to form the wave that is represented in the simulation. 2. This wave is the summation of all the photons being introduced with every oscillation, and as they continue to travel, the amplitude . This occurs because the photons are emitted in coherent fashion (constructive interference); however, amplitude when the photons overlap in an incoherent fashion (destructive interference). 3. In a laser device, a small portion of photons are permitted to escape (for use in an application). This is emulated in the simulation, where Damping represents the loss of photons. When Damping is set to Lots the amplitude compared to when Damping is set to None. 4. The generation of multiple wavelengths is possible in some laser producing systems, and the diffraction angle can be to allow the isolation of different wavelengths. 5.
