A block of mass m is suspended by a vertically oriented spring. If the mass of a block is increased to 4m, how does the frequency of oscillation change, if at all? O The frequency would be increased to two times its initial value O The frequency would be reduced by a factor of V2 2 O The frequency would be reduced to one-fourth of its initial value O The frequency would be reduced to one-half of its initial value O The frequency would be unchangedThe two arms of a U-tube are not identical, one having 5 times the diameter of the other. A cork in the narrow arm requires a force of F1 = 51 N to remove it. The tube is filled with water and the wide arm is fitted with a piston with area A2. What is the minimum force, F2, that must be applied to the piston to push the cork out? Please round your answer to the nearest whole number (integer)
