Answer:
2 m
Explanation:
Work = force × distance
500 J = 250 N × d
d = 2 m

The gravitational force between two objects is given by:
![F=G \frac{m_1 m_2}{r^2}](https://tex.z-dn.net/?f=F%3DG%20%5Cfrac%7Bm_1%20m_2%7D%7Br%5E2%7D%20)
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is their separation
In this problem, the first object has a mass of
![m_1=0.60 kg](https://tex.z-dn.net/?f=m_1%3D0.60%20kg)
, while the second "object" is the Earth, with mass
![m_2=5.97 \cdot 10^{24}kg](https://tex.z-dn.net/?f=m_2%3D5.97%20%5Ccdot%2010%5E%7B24%7Dkg)
. The distance of the object from the Earth's center is
![r=1.3 \cdot 10^7 m](https://tex.z-dn.net/?f=r%3D1.3%20%5Ccdot%2010%5E7%20m)
; if we substitute these numbers into the equation, we find the force of gravity exerted by the Earth on the mass of 0.60 kg:
Answer
Explanation:
Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs. Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis. Cigarette smoking causes most cases of lung cancer.
Answer:
The soda is being sucket out at a rate of 3.14 cubic inches/second.
Explanation:
R= 2in
S= π*R²= 12.56 inch²
rate= 0.25 in/sec
rate of soda sucked out= rate* S
rate of soda sucked out= 3.14 inch³/sec
