(3i+5)) m/s. The range of the projected ball (in m) is: ( ). Q13: If the launching angle of a projected ball is 60", then the ratio of the maximum height to the range (H/R) is:( ). = Q14: If F₁ (31+ 2J)N, F₂=(1-3))N, then the magnitude of the resultant force is: (N₂ Q15: If an analogue balance is used to measure the mass of an object m= 3.24 kg. then the uncertainty Am (kg) is: (.......... Part 3: True or False (10 points) Put true or false beside each sentence 916: The uncertainty in a ruler is 0.005 cm. ( ) 017: The coefficient of kinetic friction is larger than the coefficient of static friction for the same surface. ( Y 018: The range of a projected ball is maximum when the launching angle 0-45°. ( 019: In the figure shown, the acceleration of the system increases when M increases. ( 020: At equilibrium, the velocity of a system remains constant. ( 14 (استطال) داری بوشله الحرام و e) 1.0
