Which of the following statements is false regarding exposure and dose to air or soft tissue? the mass energy absorption coefficients (hp) for air and soft tissue are approximately equal over a broad range of photon energies the definition 1 r 2.58x104 c kgestablishes an approximate equality between exposure in the unit of roentgen and dose to soft tissue under the condition of charged particle equilibrium and in units of rad or rem exposure in the unit of roentgen is a factor of 1.14 greater than the dose to air under the condition of charged particle equilibrium and in the unit of rad a. c b. d. the average energy required to produce one coulomb of charge in dry air is 33.7 j exposure is defined for any form of uncharged ionizing radiation that can produce ion pairs in air

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off
