Answer:
Explanation:
The energy of a photon is given by:
where
h is the Planck constant
f is the frequency of the photon
In this problem, we have:
is the frequency of the photon
Substituting into the equation, we find:
The angle of the resultant vector, rounded to the nearest tenth is determined as 36.9⁰.
<h3>
Magnitude of components vectors</h3>
The resultant vector of the three vectors can be determined from the magnitude of the components vectors.
Ex = 2
Fx = 4
Gx = 2
Ey = 2
Fy = 1
Gy = 3
∑Vx = Ex + Fx + Gx = 2 + 4 + 2 = 8
∑Vy = Ey + Fy + Gy = 2 + 1 + 3 = 6
<h3>Angle of the resultant vector</h3>
tanθ = Vy/Vx
tanθ = 6/8
tanθ = 0.75
θ = tan⁻¹(0.75)
θ = 36.9⁰
Thus, the angle of the resultant vector, rounded to the nearest tenth is determined as 36.9⁰.

Answer:
the affirmation is False
Explanation:
This expression can be analyzed using Newton's laws and specifically Newton's third law that establishes that the force that one body (1) exerts on another body (2) is of the same magnitude as the force exerted by the second body on the first, but in the opposite direction.
Based on this law, the body applies a force to the box and the box reacts with a force on the string of equal magnitude, no matter if it is moving or not, but it contrary direction,
in view of this explanation the affirmation is False
