Answer:
T1 = 675 [N] ; T2 = 707.5 [N]
Explanation:
To solve this problem we must draw a free body diagram, where the bird is located, the posts and distances mentioned.
In the attached image we can see the free body diagram with different forces, angles and distances.
By conducting a distance analysis we can find the angles on both sides of the rope relative to the horizontal.
Then we perform a force analysis on the X-axis and the y-axis in order to find the two equations we need to find the stresses in the cables (T1 & T2)
Answer:
They established the laws of planetary motion. They explained how the Sun rises and sets. They made astronomy accessible to people who spoke Italian.
Explanation:
75 because 25 plus 75 equals 90
This problem can be answered using the equation below:
c = frequency x wavelength
where: c is the speed of light, which is equal to 3.00 x
10^8 m / s
frequency = c / wavelength
= (3.00 x 10^8m /s) / (2.40 x 10^-5 cm x 1 m /100cm)
= (3.00 x 10^8 m/s) / 2.40 x 10^-7m
= 1.25 x 10^15/s 1 / s = 1Hz
Frequency = 1.25 x 10^15Hz
B. Teens are still growing and require more energy for building bones and muscle.
