Answer: short wavelength, high frequency
Explanation:
Gamma rays are highly energetic electromagnetic waves. High energy implies high frequency.
E = h ν
h is the Planck's constant, ν is the frequency.
For electromagnetic radiation, frequency is inversely proportional to wavelength. Thus, gamma rays have high frequency but short wavelength.
The frequency of gamma rays is greater than 10¹⁹ Hz and wavelength is less 10⁻¹² m.
With that information you can only suppose a uniformly accelerated motion. This is, acceleration is constant.
Then, acceleration = change in velocity / change in time = (58 -54)km/h / 2 h = 4km/h / 2 h = 2 km/h^2
Then the equation for velocity, V is
V = Vo + a*t = Vo + 2 (km/h^2) * t = Vo + 2t
Vo is the initial velocity, which you can find using V = 54km/h and t = -2
Vo = V after 2 hours - a*(2hours) = 54km/h - 2(km/h^2)*2h = 54km/k - 4km/h = 50km/h
Then, the equation is: V = 50 km/h + 2t
Valid for constant acceleration.
<span>Light travels Slower in a material with a higher index of refraction.
because </span><span>Water has a higher index of refraction than air and it travels slower (bends) in water
high index mean slow travel

A satellite is a body that revolves around another larger body. Where the larger body has a stronger gravitational pull on the smaller body, keeping it in orbit. Thus the moon is the satellite of the Earth is a good example of this.
