Answer:
In the past, astronomers look into the sky and the universe as a whole with an idea that it is a place where stars are born, transition through their life stages and ultimately die and this is because they couldnt differentiate between stars, quasars and active galaxies because with advanced equipment, they all look similar but as they technological ages arrived, they were able see that they are not the same.
the answer is sex drive, I just took the test
Answer:
If you throw a pebble into a pond, ripples
spread out from where it went in. These
ripples are waves travelling through the
water. The waves move with a transverse
motion.
Explanation:
It would still be eastward because The direction of the velocity vector is always in the same direction as the direction which the object moves.
Answer:
![\frac{g_{2}}{g_{1}} = \frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bg_%7B2%7D%7D%7Bg_%7B1%7D%7D%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
Explanation:
The period of the simple pendulum is:
![T = 2\pi\cdot \sqrt{\frac{l}{g} }](https://tex.z-dn.net/?f=T%20%3D%202%5Cpi%5Ccdot%20%5Csqrt%7B%5Cfrac%7Bl%7D%7Bg%7D%20%7D)
Where:
- Cord length, in m.
- Gravity constant, in
.
Given that the same pendulum is test on each planet, the following relation is formed:
![T_{1}^{2}\cdot g_{1} = T_{2}^{2}\cdot g_{2}](https://tex.z-dn.net/?f=T_%7B1%7D%5E%7B2%7D%5Ccdot%20g_%7B1%7D%20%3D%20T_%7B2%7D%5E%7B2%7D%5Ccdot%20g_%7B2%7D)
The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:
![\frac{g_{2}}{g_{1}} = \left(\frac{T_{1}}{T_{2}} \right)^{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bg_%7B2%7D%7D%7Bg_%7B1%7D%7D%20%3D%20%5Cleft%28%5Cfrac%7BT_%7B1%7D%7D%7BT_%7B2%7D%7D%20%5Cright%29%5E%7B2%7D)
![\frac{g_{2}}{g_{1}} = \left(\frac{2\,s}{4\,s} \right)^{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bg_%7B2%7D%7D%7Bg_%7B1%7D%7D%20%3D%20%5Cleft%28%5Cfrac%7B2%5C%2Cs%7D%7B4%5C%2Cs%7D%20%5Cright%29%5E%7B2%7D)
![\frac{g_{2}}{g_{1}} = \frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bg_%7B2%7D%7D%7Bg_%7B1%7D%7D%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
