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? 436 Hz 442 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 vary independently Cp is generally greater than Cv 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 250 units 300 units 11.7 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 Number of loops Resistance of the circuit Volt Length of the wire 6. A dynamo converts mechanical energy to: Electrical energy Kinetic energy Thermal energy Potential energy 7. This is correct for capacitors in Both parallel and series None of them Parallel 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= 260 E= 90 , P= 90, N= 90 E= 88 , P= 90, N= 90 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 an electron Equal to the mass of a proton Varies depending on its energy Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11
