ETEA MDCAT 2022 PAPER (PART 13) 1. The time period of a simple pendulum with mass m, is T. When the pendulum’s mass m is replaced by another ball of mass 3 times the older mass such that the length of pendulum is not changed then its new time period will be: 3T T T/3 2T 2. The velocity of a wave is v, its time period is T and { is its frequency. Then the correct equation for frequency is: T=v/T 1f=1/T 1f=v+T T=vf 3. Which of the following contains the same number of molecules as 22 gram of carbon dioxide? 2g of hydrogen gas 32g of oxygen gas 9g of water 71g of chlorine gas 4. Molecular mass of the compound is 60 and its empirical formula is CH,0. What will be the molecular formula of the compound? C2H4O2 C2H6O2 C2H8O2 C6H12O6 5. Greater the wavelength associated with the photon: Greater the wavelength associated with the photon: Smaller is its energy Its energy will remain constant its energy will be variable 6. Identify the compound given below which has bonds formed by overlapping of sp and p orbitals: NH3 BeCl2 BF3 H2O 7. Which of the following elements has highest ionization energy? C O Be N 8. Which of the following shows marked deviation from ideal behaviour at a given temperature and pressure? H2 He CO2 N2 9. Exceptionally low acidic strength of HF is due to: Strong hydrogen bonding Smaller size of fluorine More electronegativity of fluorine Strong polar bond between H & F 10.
