Answer:
she will fall to an height of 21.09° only, beyond such an height ; the spring will break.
Katya will not be able to swing to the platform because the angle will be between -21.09° and 21.09° from vertical
Explanation:
If the distance is from the point of angle A to angle B , partitioned by a perpendicular line in the middle then, The conservation of energy between A and B can be expressed as :
![KE_A +PE_B = KE_B + PE_B](https://tex.z-dn.net/?f=KE_A%20%2BPE_B%20%3D%20KE_B%20%2B%20PE_B)
![0 + mgh = \frac{1}{2}mv_B^2+ 0](https://tex.z-dn.net/?f=0%20%2B%20mgh%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv_B%5E2%2B%200)
where ; the height h = ![l ( cos \theta - \frac{1}{2})](https://tex.z-dn.net/?f=l%20%28%20cos%20%5Ctheta%20-%20%5Cfrac%7B1%7D%7B2%7D%29)
![mgl ( cos \theta - \frac{1}{2}) = \frac{1}{2}mv^2_B](https://tex.z-dn.net/?f=mgl%20%28%20cos%20%5Ctheta%20-%20%5Cfrac%7B1%7D%7B2%7D%29%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2_B)
![\frac{mv_B^2}{l} = mg (2 cos \theta -1 )](https://tex.z-dn.net/?f=%5Cfrac%7Bmv_B%5E2%7D%7Bl%7D%20%3D%20mg%20%282%20cos%20%5Ctheta%20-1%20%29)
![T = \frac{mv_B^2}{l}+ mg cos \theta](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7Bmv_B%5E2%7D%7Bl%7D%2B%20mg%20cos%20%5Ctheta)
T = mg(3 cos θ - 1)
Given that:
T = 180 % = 1.8 mg
Then:
1.8 mg = mg(3 cos θ - 1)
2.8 mg = (3 cos θ - 1)
cos θ = ![\frac{2.8}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2.8%7D%7B3%7D)
θ = cos ⁻¹ (0.933)
θ = 21.09°
Therefore, she will fall to an height of 21.09° only, beyond such an height ; the spring will break.
Katya will not be able to swing to the platform because the angle will be between -21.09° and 21.09° from vertical
The sound wave produced can be described As a longitudinal wave of constant frequency
Longitudinal waves are waves in which the displacement of the medium is in the same direction as or the opposite direction to , the direction of travel of the wave. In a constant frequency, our brain will acknowledge this wave as 'sound'
Answer:
The answer is "folding".
Explanation:
It is a physical reconfiguring of the process, which gives a fabric a softer, lightweight shape. It is achieved in a far less simple space to carry or store products.
- When one places effect sizes on each other, instead move the different ends to each other and fold and roll it, its linear function of Folding would be illustrated.
- Except in geography, the piling process naturally creates space to makes the surface clearer and lighter.
<h3>Answer:</h3>
B produces the highest tides on Earth
A and D produce the lowest tides on Earth
This can be solve by using the formula
x = (v^2) (sin 2a) / gwhere v is the intial velocitya is the angle of trajectoryg is the acceleration due to gravity (9.8 m/s2)
x = (15.5^2) (sin 2(34) / 9.8x = 22.73 m
