Answer:
The magnitude of the rate of change of the child's momentum is 794.11 N.
Explanation:
Given that,
Mass of child = 27 kg
Speed of child in horizontal = 10 m/s
Length = 3.40 m
There is a rate of change of the perpendicular component of momentum.
Centripetal force acts always towards the center.
We need to calculate the magnitude of the rate of change of the child's momentum
Using formula of momentum
![\dfrac{dp}{dt}=F](https://tex.z-dn.net/?f=%5Cdfrac%7Bdp%7D%7Bdt%7D%3DF)
![\dfrac{dP}{dt}=\dfrac{mv^2}{r}](https://tex.z-dn.net/?f=%5Cdfrac%7BdP%7D%7Bdt%7D%3D%5Cdfrac%7Bmv%5E2%7D%7Br%7D)
Put the value into the formula
![\dfrac{dP}{dt}=\dfrac{27\times10^2}{3.40}](https://tex.z-dn.net/?f=%5Cdfrac%7BdP%7D%7Bdt%7D%3D%5Cdfrac%7B27%5Ctimes10%5E2%7D%7B3.40%7D)
![\dfrac{dP}{dt}=794.11\ N](https://tex.z-dn.net/?f=%5Cdfrac%7BdP%7D%7Bdt%7D%3D794.11%5C%20N)
Hence, The magnitude of the rate of change of the child's momentum is 794.11 N.
The evidence of this research is published in the scientific journal Nature communication.
<u>Explanation:</u>
Our solar system shaped about 4.5 billion years prior from a thick haze of interstellar gas and residue. The cloud crumbled, potentially due to the shock wave of a close by detonating star, called a supernova. At the point when this residue cloud crumbled, it framed a sun powered cloud—a turning, whirling plate of material.
The research is distributed in the latest issue of journal Nature Communications. About 4.6 billion years prior, a haze of gas and residue that in the end framed our nearby planetary group was upset. The following gravitational breakdown framed the proto-Sun with an encompassing plate where the planets were conceived.
Answer:
Length of pipe organ(L) = 0647 m (Approx)
Explanation:
Given:
Temperature (T) = 14°C
Fundamental frequency (F) = 262 Hz
Speed of sound (v) = 331 + 0.60(T) m/s
Find:
Length of pipe organ(L)
Computation:
Speed of sound (v) = 331 + 0.60(14) m/s
Speed of sound (v) = 339.4
Length of pipe organ(L) = Speed of sound (v) / 2(Fundamental frequency)
Length of pipe organ(L) = 339.4 / 2 (262)
Length of pipe organ(L) = 0647 m (Approx)
