Answer:
The height of the object is 5007.4 miles.
Explanation:
Given that,
Weight of object = 200 lb
We need to calculate the value of 
Using formula of gravitational force

Put the value into the formula



We need to calculate the height of the object
Using formula of gravitational force

Put the value into the formula





Hence. The height of the object is 5007.4 miles.
Answer:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
Explanation:
Explanation. A gas will expand to fill its container. Pulling the plunger of the syringe creates a low pressure inside the syringe (a vacuum)
The combined
gas law does not account for changes in power. The combined gas law has no official founder; it is simply
the incorporation of the three laws that was discovered. The combined gas law
is a gas law that combines Gay-Lussac’s Law, Boyle’s Law and Charle’s Law. Boyle’s law states that pressure is inversely
proportional with volume at constant temperature. Charle’s law states that
volume is directly proportional with temperature at constant pressure. And
Gay-Lussac’s law shows that pressure is directly proportional with temperature
at constant volume. The combination of these laws known now as combined gas law
gives the ratio between the product of pressure-volume and the temperature of
the system is constant. Which gives PV/T=k(constant). When comparing a
substance under different conditions, the combined gas law becomes P1V1/T1 =
P2V2/T2.
