The rain gets evaporated in to water vapor and is returned to the clouds where they go through condensation and then they poud down as rain or A.K.A, Precipitation.
Answer: During sexual reproduction, the genetic material of two individuals is combined to produce genetically-diverse offspring that differ from their parents. The genetic diversity of sexually-produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment
Answer:
60 000 N
Explanation:
1 pa = 1 N/m^2
you have 300 000 of these = 300 000 N /m^2
but only an area of .2 m^2
300 000 N / m^2 * .2 m^2 = 60 000 N
Answer: The unit of impulse is applied to an object produces an equivalent vector change in its linear momentum, also in the same direction.
Explanation:
Answer:
![\rm KE\pm \Delta KE = 17.6\pm 6.8\ J.](https://tex.z-dn.net/?f=%5Crm%20KE%5Cpm%20%5CDelta%20KE%20%3D%2017.6%5Cpm%206.8%5C%20J.)
Explanation:
<u>Given:</u>
- Mass,
- Velocity,
![\rm v\pm \Delta v = 5.2\pm 0.2\ m/s.](https://tex.z-dn.net/?f=%5Crm%20v%5Cpm%20%5CDelta%20v%20%3D%205.2%5Cpm%200.2%5C%20m%2Fs.)
where,
are the uncertainties in mass and velocity respectively.
The kinetic energy is given by
![\rm KE = \dfrac 12 mv^2 = \dfrac 12 \times 1.3\times 5.2^2=17.576\approx 17.6\ J.](https://tex.z-dn.net/?f=%5Crm%20KE%20%3D%20%5Cdfrac%2012%20mv%5E2%20%3D%20%5Cdfrac%2012%20%5Ctimes%201.3%5Ctimes%205.2%5E2%3D17.576%5Capprox%2017.6%5C%20J.)
The uncertainty in kinetic energy is given as:
![\rm \dfrac{\Delta KE}{KE}=\dfrac{\Delta m}{m}+\dfrac{2\Delta v}{v}\\\dfrac{\Delta KE}{17.6}=\dfrac{0.4}{1.3}+\dfrac{2\times 0.2}{5.2}\\\dfrac{\Delta KE}{17.6}=0.384\\\Rightarrow \Delta KE = 17.6\times 0.384 = 6.7854\ J\approx6.8\ J\\\\Thus,\\\\KE\pm \Delta KE = 17.6\pm 6.8\ J.](https://tex.z-dn.net/?f=%5Crm%20%5Cdfrac%7B%5CDelta%20KE%7D%7BKE%7D%3D%5Cdfrac%7B%5CDelta%20m%7D%7Bm%7D%2B%5Cdfrac%7B2%5CDelta%20v%7D%7Bv%7D%5C%5C%5Cdfrac%7B%5CDelta%20KE%7D%7B17.6%7D%3D%5Cdfrac%7B0.4%7D%7B1.3%7D%2B%5Cdfrac%7B2%5Ctimes%200.2%7D%7B5.2%7D%5C%5C%5Cdfrac%7B%5CDelta%20KE%7D%7B17.6%7D%3D0.384%5C%5C%5CRightarrow%20%5CDelta%20KE%20%3D%2017.6%5Ctimes%200.384%20%3D%206.7854%5C%20J%5Capprox6.8%5C%20J%5C%5C%5C%5CThus%2C%5C%5C%5C%5CKE%5Cpm%20%5CDelta%20KE%20%3D%2017.6%5Cpm%206.8%5C%20J.)
