Answer: units are interrelated in such a way that one unit is derived from other units without conversion factors. ... SI is used in most places around the world, so our use of it allows scientists from disparate regions to use a single standard in communicating scientific data without vocabulary confusion.
Explanation:
Answer:
Micro and radio waves.
Lower energy.
Gamma rays.
Explanation:
The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths.
Ionising radiation os defined as the energy required of photons of a wave to ionize atoms, causing chemical reactions.
The energy of the wave depends on both the amplitude and the frequency. If the energy of each wavelength is a discrete packet of energy, a high-frequency wave will deliver more of these packets per unit time than a low-frequency wave. In summary, the longer the wavelength, the lower the energy to ionise.
The velocity of a wave is directly proportional to the frequency of that wave.
c = f * lambda
Where,
c = velocity of the wave
f = frequency of the wave = 1/time
Lambda = wavelength.
From the above expression, the longer the wavelength, lambda the shorter the frequency.
Examples of waves with longer wavelengths are, micro and radio waves, while radiations with shorter wavelengths like gamma rays.
let the plane is flying at some angle theta with west towards north
Now we can use the components
now since plane has to fly towards west so net speed in north must be equal to speed in south for air
So we can say
so plane has to fly in direction 14.5 degree North of west
Answer:
5.648 N/C
Explanation:
Given:
q₁ = 60 pC/m² = 60 × 10⁻¹² C/m²
q₂ = -80 pC/m² = - 80 × 10⁻¹² C/m²
Now,
Electric field is given as:
E =
ε₀ = Permittivity of Free Space
thus, due to charge q₁
E₁ =
or
E₁ = 3.389 N/C
and, due to charge q₂
E₂ =
or
E₂ = 4.519 N/C
Now,
The resultant electric field =
or
The resultant electric field =
or
The resultant electric field =
or
The resultant electric field = 5.648 N/C
The masses of both objects and the distance between their centers.
