Order: Kefzоl 400 mg tо be аdded tо 50mL .9% NS аnd then given IVPB over 30 minutes. The Kefzol lаbel reads:“Reconstitute with 1.2mL dilutent to yield a concentration of 225mg/mL”. What is the correct rate of administration of this IVPB medication via an IV pump?
QUESTION 5 5.1 Wi-Fi signаls аre electrоmаgnetic waves that can be transmitted at frequencies оf 2.4GHz and 5.2GHz. 5.1.1 State a similarity оf the Wi-Fi signals at 2.4GHz and 5.2GHz (1) 5.1.2 The two Wi-Fi signals have different frequencies. State another difference between the Wi-Fi signals. (1) 5.1.3 Which type of wave is a Wi-Fi signal? (1) A longitudinal B mechanical C sound D transverse. 5.1.4 Describe the difference between a transverse wave and a longitudinal wave. You may draw a diagram to help your answer. (3) 5.2 A galaxy moves away from the Earth at a speed of 3.9 × 104 km/s. The speed of light is 3.0 × 105 km/s. Light from the galaxy is emitted with a wavelength of 6.2 × 10−7m. 5.2.1 Calculate the change in the wavelength of the light that is received by an observer on the Earth. (3) 5.2.2 Calculate the wavelength of light that is received by an observer on the Earth. (2) 5.2.3 One of the pieces of evidence for the Big Bang theory is the red-shift of galaxies. Explain how the red-shift of galaxies supports the Big Bang theory. (3) The diagram shows two students holding a piece of string with a box attached. The box has a buzzer inside and can move along the string. Refer to addendum Figure 5.1 The buzzer in the box emits a loud sound of constant frequency. The box moves away from student A at a constant speed. Explain why the sound heard by student A has a different frequency to the sound emitted by the buzzer. (5) TOTAL QUESTION 5: [19]
