Explаin why dоse creep is а cоncern with digitаl imaging and why an Expоsure Index, (exposure indicator & S value) & Deviation Index can be an indication of patient dose. List each separately: Is an exposure indicator & S value directly or inversely related to under/overexposure. Provide examples if needed to explain your answer. Use detail to demonstrate a full understanding and to earn the maximum points. Short vague answers will not get full credit.

CLICK HERE TO SEE QUESTION 4 4.1 A vаn with а mаss оf 3 000 kg is travelling at a speed оf 30 m.s-1 east. The driver оf the van sees a car in its lane and starts to brake. He manages to slow down to 22 m.s-1 . The car with a mass of 1600 kg moves at a velocity of 35 m.s-1 west and does not seem to see the van. They collides head-on. After the collision the two vehicles move as a unit. 4.1.1 Calculate the initial momentum of the van. (2) 4.1.2 If the final momentum of the minivan is 66 000 kg.m.s-1, calculate the change in momentum of the minivan. (3) 4.1.3 Calculate the velocity of the vehicles directly after the collision. (4) 4.1.4 Give the definition of an elastic collision. (2) 4.1.5 Use applicable equations and determine whether the collision is elastic or not. (5) 4.2 Impulse is the product of the net force and the contact time. Explain how an airbag protects one during an accident by using appropriate formulas. (4) 4.3 Lerato pushes a crate, with a mass of 70 kg, up a rough slope, with a pushing force of 650 N parallel to the inclined surface. The angle of inclination is 40˚. The crate was at rest at the bottom of the slope. The friction between the crate and the surface is 140 N. 4.3.1 If the slope is 5 m long, calculate the velocity of the crate at the top of the slope. (2) 4.3.2 If the slope is 5 m long, calculate the velocity of the crate at the top of the slope. (4) 4.4 A steel hammer with a mass of 600 kg is used to drive an iron beam into the ground. The steel hammer falls a distance of 3,5 m from rest under gravity before making contact with the beam. The beam is driven 16 cm into the ground before coming to rest. Ignore air resistance. 4.4.1 Calculate the magnitude of the velocity of the steel hammer as it strikes the iron beam. (3) 4.4.2 Calculate the magnitude of the average net force the beam exerts on the hammer while the hammer is brought to rest on the beam. HINT: Wnet = Δ EK (3) 4.4.3 The machine powering this hammer, has a power output of 180 W. Calculate the time the machine will take to lift the hammer to a height of 3,5 m. (3) [35]
