Answer:
2m/s/s
Explanation:
The formula goes- F=MA
F-Force M-Mass & A-Acceleration
We need to rearrange this formula to find the acceleration-
A=F/M
All we need to do now is substitute the values in
A=2000N/1000kg
A=2m/s^2
In the given option the last option (2m/s/s) would be the ans, as it's the same as 2m/s^2
So ya, I guess that's all
They did not believed Galileo's discoveries because religiouse reasons the preast said that all the bible is true but Galileo despised it.
lovely question hope 7 solve it
Explanation:
Answer:
The space cadet that weighs 800 N on Earth will weigh 1,600 N on the exoplanet
Explanation:
The given parameters are;
The mass of the exoplanet = 1/2×The mass of the Earth, M = 1/2 × M
The radius of the exoplanet = 50% of the radius of the Earth = 1/2 × The Earth's radius, R = 50/100 × R = 1/2 × R
The weight of the cadet on Earth = 800 N
![The \ weight, W =G\dfrac{M \times m}{R^{2}} = 800 \ N](https://tex.z-dn.net/?f=The%20%5C%20weight%2C%20W%20%20%3DG%5Cdfrac%7BM%20%5Ctimes%20m%7D%7BR%5E%7B2%7D%7D%20%3D%20800%20%5C%20N)
Therefore, for the weight of the cadet on the exoplanet, W₁, we have;
![W_1 =G\dfrac{\dfrac{M}{2} \times m}{ \left ( \dfrac{R}{2} \right ) ^{2}} = G\dfrac{\dfrac{M}{2} \times m \times 4}{ R ^{2}} = 2 \times G \times \dfrac{M \times m}{R^{2}} = 2 \times 800 \, N = 1,600 \, N](https://tex.z-dn.net/?f=W_1%20%20%20%3DG%5Cdfrac%7B%5Cdfrac%7BM%7D%7B2%7D%20%20%5Ctimes%20m%7D%7B%20%5Cleft%20%28%20%5Cdfrac%7BR%7D%7B2%7D%20%5Cright%20%29%20%5E%7B2%7D%7D%20%3D%20G%5Cdfrac%7B%5Cdfrac%7BM%7D%7B2%7D%20%20%5Ctimes%20m%20%5Ctimes%204%7D%7B%20R%20%5E%7B2%7D%7D%20%3D%202%20%5Ctimes%20G%20%5Ctimes%20%20%5Cdfrac%7BM%20%5Ctimes%20m%7D%7BR%5E%7B2%7D%7D%20%3D%202%20%5Ctimes%20800%20%5C%2C%20N%20%3D%201%2C600%20%5C%2C%20N)
The weight of a space cadet on the exoplanet, that weighs 800 N on Earth = 1,600 N.
They have the same velocity because their displacements (shortest line from point A to point B, which is a straight line) are the same and they meet at the same time.
