Physics

Identify each type of radiation as ionizing or non-ionizing. remember that ionizing radiation deposits enough energy when absorbed in a material such that electrons are removed from atoms to create charged ions.
non-ionizing: visible light
ionizing: alpha particles (he nuclei)
non-ionizing: microwaves
ionizing: gamma rays
non-ionizing: infrared
ionizing: beta particles (electrons, positrons)
non-ionizing: radio waves
ionizing: x-rays

17kN

Explanation:

The force of 10 kN in the cable and the load of 10 kN both have a component along the crane arm.

The force F exerted by the crane arm on the pulley is the sum of these 2 components.

Component of force in cable along the crane arm = 10 cos 30°

Component of load along the crane arm = 10 cos 30°

Considering the forces on the pulley,

F = 10 cos 30° + 10 cos 30°

Force F = 17.32 kN = 17 kN
