Why is thermal energy from the Sun transferred to Earth through electromagnetic waves instead of any other type of thermal energ
Pachacha [2.7K]

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".

The emission line used for zinc determinations in atomic emission spectroscopy is 214 nm. If there are 9.00×1010 atoms of zinc e
KengaRu [80]

Answer:

8.4\cdot 10^{-8}J

Explanation:

The energy emitted by a single photon is given by:

E=\frac{hc}{\lambda}

where

h is the Planck constant

c is the speed of light

\lambda is the wavelength of the photon

For the photons emitted by the zinc atoms,

\lambda = 214 nm = 214 \cdot 10^{-9} m

So the energy of a single photon emitted is

E=\frac{(6.63\cdot 10^{-34})(3\cdot 10^8)}{214\cdot 10^{-9}}=9.3\cdot 10^{-19}J

And since the number of atoms is

N=9.0\cdot 10^{10}

The total energy emitted will be

E=NE_1 = (9.0\cdot 10^{10})(9.3\cdot 10^{-19})=8.4\cdot 10^{-8}J

At what angle should the roadway on a curve with a 50m radius be banked to allow cars to negotiate the curve at 12 m/s even if t
kari74 [83]

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;

\theta = tan^{-1} (\frac{v^2}{gr} )

where;

θ is the road bank angle

g is acceleration due to gravity = 9.8 m/s²

\theta = tan^{-1} (\frac{v^2}{gr} )\\\\\theta = tan^{-1} (\frac{12^2}{9.8 \times 50} )\\\\\theta = tan^{-1} ( 0.2939)\\\\\theta = 16.38 ^0

Therefore, the road bank angle is 16.38⁰.
