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 is generally greater than Cv Cp and Cv are always equal Cp and Cv vary independently 3. If the Cp value is 220 units, what could be a possible value for the Cv value? 220 units 11.7 units 250 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? 4 0.4 2 0.2 5. The emf produced be generator depends upon Number of loops Length of the wire Resistance of the circuit Volt 6. A dynamo converts mechanical energy to: Potential energy Electrical energy Kinetic energy Thermal energy 7. This is correct for capacitors in Both parallel and series Parallel None of them Series 8. In , the number of (E) electron , (P) protons and (N) neutrons are E= 90 , P= 88, N= 350 E= 88 , P= 90, N= 90 E= 90 , P= 90, N= 90 E= 88 , P= 90, N= 260 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 Varies depending on its energy Zero Equal to the mass of an electron Equal to the mass of a proton Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11
