I'd say A) atmosphere but i'm not very sure
Answer:
b option mass will not change based on location while weight will changr based on gravitational pull
bcz in the formula of weight w=mg
so w is directly proportional to g
Answer:
1.3 m/s
Explanation:
It is given that,
Mass of bird A, ![m_A=2.2\ kg](https://tex.z-dn.net/?f=m_A%3D2.2%5C%20kg)
Mass of bird B, ![m_B=1.7\ kg](https://tex.z-dn.net/?f=m_B%3D1.7%5C%20kg)
Initial speed of bird A is 0 as it was at rest
Initial speed of bird B is 3 m/s
We need to find the velocity of the center of mass for this system of two birds. Let it is V. so,
![v_{cm}=\dfrac{m_Au_A+m_Bu_B}{m_A+m_B}\\\\v_{cm}=\dfrac{2.2\times 0+1.7\times 3}{2.2+1.7}\\\\v_{cm}=1.3\ m/s](https://tex.z-dn.net/?f=v_%7Bcm%7D%3D%5Cdfrac%7Bm_Au_A%2Bm_Bu_B%7D%7Bm_A%2Bm_B%7D%5C%5C%5C%5Cv_%7Bcm%7D%3D%5Cdfrac%7B2.2%5Ctimes%200%2B1.7%5Ctimes%203%7D%7B2.2%2B1.7%7D%5C%5C%5C%5Cv_%7Bcm%7D%3D1.3%5C%20m%2Fs)
So, the center of mass for this system is 1.3 m/s.
Answer:
that jet will fly 1200 km in 2 hours
When it comes to organisms that help speed up the decay of biomes, worms
are wonderful creatures. They take almost anything that falls to the
earth and slowly erode it. Fungi is another option.
