i squared r = 0.03x0.03x1000=3x0.03x10=.9W
Answer:
Explanation:
For simple pendulum the formula is
Where T is time period , l is length and g is acceleration due to gravity .
n is frequency
Putting the values
l = 1.584 m
<span>To answer this problem, we use balancing of forces: x and y components to determine the tension of the rope.
First, the vertical component of tension (Tsin theta) is equal to the weight of the object.
T * sin θ = mg =</span> 1.55 * 9.81 <span>
T * sin θ = 15.2055
Second, the horizontal component of tension (t cos theta) is equal to the force of the wind.
T * cos θ = 13.3
Tan θ = sin </span>θ / cos θ = 15.2055/13.3 = 1.143
we can find θ that is equal to 48.82.
T then is equal to 20.20 N
