BALOCHISTAN MDCAT PAPER 2021 MDCAT 2021 ( 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? 446 Hz 436 Hz 434 Hz 442 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? Cp is generally greater than Cv Cp and Cv vary independently Cp and Cv are always equal Cv is generally greater than Cp 3. If the Cp value is 220 units, what could be a possible value for the Cv value? 220 units 11.7 units 300 units 250 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? 0.4 2 0.2 4 5. The emf produced be generator depends upon Length of the wire Resistance of the circuit Volt Number of loops 6. A dynamo converts mechanical energy to: Kinetic energy Potential energy Thermal energy Electrical energy 7. This is correct for capacitors in Series None of them Parallel Both parallel and series 8. In , the number of (E) electron , (P) protons and (N) neutrons are E= 88 , P= 90, N= 260 E= 90 , P= 88, N= 350 E= 88 , P= 90, N= 90 E= 90 , P= 90, N= 90 9. If electrons are passed through an electric and magnetic field undeflected, the correct equation is: F = q(E + vB) F = q(E – vB) F = q(E / v) F = q(E x 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
