Properties of electromagnetic radiation and photons. ... we find the types of energy that are lower in frequency ( and thus longer in wavelength) than visible light. Seeee
Answer:
The magnitude of the tension in the cable, T is 1,064.315 N
Explanation:
Here we have
Length of beam = 4.0 m
Weight = 200 N
Center of mass of uniform beam = mid-span = 2.0 m
Point of attachment of cable = Beam end = 4.0 m
Angle of cable = 53° with the horizontal
Tension in cable = T
Point at which person stands = 1.50 m from wall
Weight of person = 350 N
Therefore,
Taking moment about the wall, we have
∑Clockwise moments = ∑Anticlockwise moments
T×sin(53) = 350×1.5 + 200×2
T = 850/sin(53) = 1,064.315 N.

Answer:
Option D. 1000 J.
Explanation:
From the question given above, the following data were obtained:
Force (F) applied = 200 N
Distance (s) = 5 m
Time (t) = 10 s
Workdone (Wd) =?
Workdone (Wd) is simply defined as the product of force (F) and distance (s) moved in the direction of the force. Mathematically, it is expressed as:
Wd = F × s
With the above formula, we can calculate the Workdone as illustrated below:
Force (F) applied = 200 N
Distance (s) = 5 m
Workdone (Wd) =?
Wd = F × s
Wd = 200 × 5
Wd = 1000 J
Thus, the Workdone is 1000 J
Light is described as both wave as well particle because light behave as wave in phenomenon like diffraction, interference, refraction, Doppler effect, etc whereas it behave as a particle in phenomenon like photoelectric effect, etc. Hope this helps.
