Answer:

Towards the southern of the sound

Explanation:

As the motion of the source of sound is moving,the percieved sound frequency varies .this is known as Doppler effect.the sound waves emited by the sources tends to bunch up in front of the source and spread out behind the source.

Since the falcon is moving towards the sound,the frequency increases and so does the pitch of the sound

Why is there more air pressure at sea level than on top of a mountain?
Aleks04 [339]

Answer:

The depth (distance from top to bottom) of the atmosphere is greatest at sea level and decreases at higher altitudes. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude.

What wavelength of radiation has photons of energy 5.44 x 10-18 J?
spin [16.1K]

Answer:

λ = 37 nm

Radiation is in the ultra violet region.

Explanation:

Given data:

Energy of photon = 5.44 × 10 ⁻¹⁸ J

Wavelength of photon = ?

Solution:

E = h.c / λ

λ = h. c/ E

λ = 6.63× 10⁻³⁴m² kg/s × 3×10⁸ m/s / 5.44 × 10 ⁻¹⁸ Kg m²/s²

λ = 19.89 × 10⁻²⁶ kg. m³ /s² / 5.44 × 10 ⁻¹⁸ Kg m²/s²

λ = 3.7 × 10⁻⁸ m

m to nm conversion.

λ = 3.7 × 10⁻⁸m ×10⁹ nm / 1m

λ = 37 nm

Radiation is in the ultra violet region because the rage of UV is 1 nm - 400 nm.
