ETEA MDCAT Past Paper 2021 MDCAT 16 September ( PART 2 ) 1. Which frequency for tuning fork B would generate 6 beats in 2 seconds when used alongside a tuning fork A with a frequency of 440 Hz? 436 Hz 442 Hz 446 Hz 434 Hz 2. What relationship typically holds between the specific heat at constant pressure (Cp) and the specific heat at constant volume (Cv) for most substances? Cv is generally greater than Cp Cp and Cv vary independently Cp and Cv are always equal Cp is generally greater than Cv 3. If the Cp value is 220 units, what could be a possible value for the Cv value? 11.7 units 250 units 220 units 300 units 4. For a gas with an energy change of 4 kJ and 2 moles of the gas, resulting in a temperature change of 10 C, what is the specific heat capacity (Cv) of the gas? 0.2 4 0.4 2 5. The emf produced be generator depends upon Number of loops Volt Resistance of the circuit Length of the wire 6. A dynamo converts mechanical energy to: Thermal energy Electrical energy Potential energy Kinetic energy 7. This is correct for capacitors in Parallel Both parallel and series None of them Series 8. In , the number of (E) electron , (P) protons and (N) neutrons are E= 88 , P= 90, N= 260 E= 88 , P= 90, N= 90 E= 90 , P= 90, N= 90 E= 90 , P= 88, N= 350 9. If electrons are passed through an electric and magnetic field undeflected, the correct equation is: F = q(E x v) F = q(E – vB) F = q(E + vB) F = q(E / v) 10. The mass of photon is equall to Zero Equal to the mass of a proton Varies depending on its energy Equal to the mass of an electron Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11
