Answer:
128
Step-by-step explanation:
(2³) (140/7)-32 =128
I believe you meant the equal signs to be division symbols haha. The next step would be 18/6.
a. The period of the pendulum for the given Length = 23 cm is 0.962 s
b. The period of the pendulum for the given Length = 192 cm is 2.779 s
<h3>What is time period of the pendulum?</h3>
When the bob of the pendulum is displaced from its equilibrium position and starts swinging from one end to another end or to and fro. The time taken to complete one cycle is called the time period.
The expression for finding the time period is
T = 2π√l/980
Given, the length of the pendulum l,
a. L =23 cm
Put the value into the expression of Time period, we get
T = 2π√(23/980)
T =0.962 s
a. L =192 cm
Put the value into the expression of Time period, we get
T = 2π√(192/980)
T =2.779 s

The answer is D. 76. This is because if STR is 28 degrees, and angle STU is on a straight line, all we have to do is subtract 180-28, then divide by 2.
