The International Space Station is in orbit about 420 km above the surface of Earth. Calculate how many minutes it would take for the ISS to complete one orbit. (E = 6.38 × 106 m, Mɛ = 5.98 × 1024 kg)

With the help of diagrams, indicate the three main objectives of a standard electrophysiological study (EPS). In addition, explain how the Wenckeback point (WP) is assessed. Indicate what are the values for normal and abnormal WP?

Part (b): Watts, volts, and ohms are SI units that can be expressed in the 'base' SI units as follows: kg-m² 53 ohm = kg-m² $³.A21 watt = volt= bottle cm kg.m² $3.A' (Recall that 'A' is the abbreviation for an ampere.) Use algebra and the equation at the top of the page (P=V²/R) to show that the base SI units for watts equal the base SI units for volts²/ohms. You do not need any numbers in this algebraic exercise. Instead, treat each of the base SI units (kg, m, s, A) as if it were an algebra variable (like x or y). Start with the following equation and substitute the base SI units for watt, volt, and ohm: watt = volt² ohm

QUESTION 6 Find the uncertainty in a calculated electrical potential difference from the measurements of current and resistance. Electric potential difference depends on current and resistance according to this function V(I,R) = IR. Your measured current and resistance have the following values and uncertainties 1 = 1.5 Amps, Sl = 0.2 Amps and R = 36.4 Ohms and SR 0.3 Ohms. What is the uncertainty in %3D the , SV ? Units are not needed in your answer.
