I need help with question ii) Calculate the speed of these radio waves.

Physics
1 answer:
Sergeeva-Olga [200]2 years ago
4 0

Answer:

Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.

What are the potential out comes of force
AysviL [449]

Answer:

F in the definition of potential energy is the force exerted by the force field, e.g., gravity, spring force, etc. The potential energy U is equal to the work you must do against that force to move an object from the U=0 reference point to the position r.

A rocket takes off from Earth and starts flying to Mars. What happens to the force of gravity between the rocket and Earth as th
lawyer [7]

The force of gravity between Earth and Mars will decrease.

The gravitational law is given as-

           F = G mM/r²

  here,  m= mass of rocket

             M = mass of earth

             r = distance between earth and rocket

So, as rocket takes off from earth and fly towards mars then the distance starts to increase between earth and rocket, and the gravitational pull between them starts to weaken. Then a point will reach when rocket will far from gravity of earth and could probably enter the gravity of Mars.

Temperature is a measure of how much the atoms in a substance are moving. Why is a substance hotter in the gas state than in the
dolphi86 [110]
Hey there!
In a gas state, particles have lots of energy, so they move around very rapidly, hitting each other and flowing around, that's why you see them moving so freely. Because they have so much energy, the substance is likely to be harder, as it can obtain more thermal energy, or heat.
Hope this helps!

Elden [556K]

Answer;

1 second

Explanation;

Two objects moving at the same speed will always stay the same distance apart. If two objects are moving at different speeds, the distance between them must change.

Therefore; if the distance will be the same and the speed is also the same then the time taken will be the same.
