Answer:
v = 3.78 m/s
Explanation:
given,
mass of the child = 36 Kg
length of the chain, r = 2.9 m
tension in each chain, T = 265 N
now,
Net force acting in the system
2 T - m g = m a
T is the tension in the chain
a is the acceleration in the normal direction
here, ![a = \dfrac{v^2}{r}](https://tex.z-dn.net/?f=a%20%3D%20%5Cdfrac%7Bv%5E2%7D%7Br%7D)
now,
![2 T - m g = m\dfrac{v^2}{r}](https://tex.z-dn.net/?f=2%20T%20-%20m%20g%20%3D%20m%5Cdfrac%7Bv%5E2%7D%7Br%7D)
![2\times 265 - 36\times 9.8 = 36\times \dfrac{v^2}{2.9}](https://tex.z-dn.net/?f=2%5Ctimes%20265%20-%2036%5Ctimes%209.8%20%3D%2036%5Ctimes%20%5Cdfrac%7Bv%5E2%7D%7B2.9%7D)
v² = 14.274
v = 3.78 m/s
speed of the child at the lowest point is equal to 3.78 m/s
Xrays and one of the best generators of x-beams are dark gaps. These can't be identified outwardly, yet the x-beams they create can. It demonstrates an altogether different view than optical degrees.

Answer:
8.90 x 10^-3
Explanation:
8.90 x 10^-3
It has to be 10^-3 (ten to the negative three) because when you move the decimal back to it's proper place you are moving it to the left.
and it has to be 8.90 because you have to observe correct sig figs. The 0 at the end of the number is significant because it is at the end of the number AND to the right of the decimal point.
