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? 442 Hz 436 Hz 434 Hz 446 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 and Cv are always equal Cv is generally greater than Cp Cp is generally greater than Cv Cp and Cv vary independently 3. If the Cp value is 220 units, what could be a possible value for the Cv value? 11.7 units 250 units 300 units 220 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? 2 4 0.2 0.4 5. The emf produced be generator depends upon Length of the wire Volt Resistance of the circuit Number of loops 6. A dynamo converts mechanical energy to: Thermal energy Potential energy Kinetic energy Electrical 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= 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 – vB) F = q(E x v) F = q(E + vB) F = q(E / v) 10. The mass of photon is equall to Equal to the mass of a proton Equal to the mass of an electron Varies depending on its energy Zero Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11
