- In Figure (a), string 1 has a linear density of 2.08 g/m, and string 2 has a linear density of 4.84 g/m. They are under tension due to the hanging block of mass M = 677 g. Calculate the wave speed on (a) string 1 and (b) string 2. (Hint: When a string loops halfway around a pulley, it pulls on the pulley with a net force that is twice the tension in the string.) Next the block is divided into two blocks (with M, + M2 = M) and the apparatus is rearranged as shown in Figure (b). Find (c) M1 and (d) M2 such that the wave speeds in the two strings are equal. - String 1 String 2 Knot M (а) - String 1 String 2 M1 M2 (b)The bottom says "H = 222 * (1)22 × -10 = 24.2 m". I dont understand this calculation and how the answer is 24.2 mA homeowner is told that she must increase the height of her fences 56.0% if she wants to keep the deer from jumping in to eat the foliage and blossoms. If the current fence is 2.12 m high, how high must the new fence be?
