Answer:
Electromagnetic waves can travel through empty space.
Explanation:
Electromagnetic waves are defined as the waves that are created due to the vibrations between a magnetic field and an electric field.
Earth atmosphere is made up of several gases and spaces between them. Thermal energy from the sun require to pass through space by electromagnetic radiation. Electromagnetic waves can travel through empty space and that is why other type of waves are unable to transfer thermal energy.
Hence, the correct answer is "Electromagnetic waves can travel through empty space".
Answer:

Explanation:
The energy emitted by a single photon is given by:

where
h is the Planck constant
c is the speed of light
is the wavelength of the photon
For the photons emitted by the zinc atoms,

So the energy of a single photon emitted is

And since the number of atoms is

The total energy emitted will be

I don't know what you meant 'dontk'.

Minecraft logic
Answer:
The road bank angle is 16.38⁰.
Explanation:
radius of curvature of the road, r = 50 m
allowable speed of car on the road, v = 12 m/s
The bank angle is calculated as;

where;
θ is the road bank angle
g is acceleration due to gravity = 9.8 m/s²

Therefore, the road bank angle is 16.38⁰.
