The answer is that it is true
Electromagnetic radiation waves:
They can be either infared radiation or visible light
We cannot see I fared radiation but it is how some energy is transferred
Solar energy or solar radiation
Answer:
Explanation:
According to Newton's laws of gravitation force of attraction is given by
F = GMm/R²
G = 6.67 X 10⁻¹¹
,M = 2.5 Kg ,
m = 2.5 Kg ,
R = .14 m
=
F = 6.67 X 10⁻¹¹ X 2.5 X 2.5 / 0.14²
= 2126.9 X 10 ⁻¹¹ N.

Explanation:
a) The expression for grating diffraction is
d sin θ = m λ
where d the distance between two slits, λ the wavelength and m an integer that represents the diffraction range
In this exercise we are told that the two spectra are in the same position, let's write the expression for each network
Network A
m = 1
sin θ = 1 λ / dA
Network B
m = 2
sin θ = 2 λ / dB
they ask us for the relationship between the distances, we match the equations
λ / dA) = 2 λ / dB
dB / dA = 2
b) let's write the equation of the networks
sin θ = m_A λ / dA
sin θ = m_B λ / dB
we equalize
m_A λ/ dA = m_B λ / dB
we use that
dB / dA = 2
m_A 2 = m_B
therefore the overlapping orders are
Network B Network A
