SINDH MDCAT 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? Cv is generally greater than Cp Cp is generally greater than Cv Cp and Cv vary independently Cp and Cv are always equal 3. If the Cp value is 220 units, what could be a possible value for the Cv value? 300 units 220 units 11.7 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 4 0.2 5. The emf produced be generator depends upon Volt Resistance of the circuit Length of the wire Number of loops 6. A dynamo converts mechanical energy to: Electrical energy Potential energy Thermal energy Kinetic energy 7. This is correct for capacitors in Parallel Series Both parallel and series None of them 8. In , the number of (E) electron , (P) protons and (N) neutrons are E= 90 , P= 90, N= 90 E= 88 , P= 90, N= 90 E= 88 , P= 90, N= 260 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 Equal to the mass of a proton Zero 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
