A projectil is projected vertically upwards from Earth at what height above the earth's surface will the force on the satellite due to the Earth be reduced to half its value at the Earth station?

(1/2)Gm/R2=Gm/(R+h)2
Where:
G is the gravitational constant
m is the mass of the Earth
R is the Radius of the Earth
h is the height above the Earth where Gravity is 1/2 surface gravity
Canceling Gm from both sides gives:
1/2R2 = 1/(R+h)2
inverting to make things simpler:
2R2 = (R+h)2
taking the square root of both sides:
sqrt(2)R=R+h
(sqrt(2)-1)R=h
the sqrt(2)=1.4142135623730950488016887242097
(sqrt(2)-1) = 0.4142135623730950488016887242097
so h=0.4142 R
The required height is 0.41 times the radius of Earth.

What causes reduced visibility in the mountains?
Most mountains are very close to or are touching clouds, which causes a fog and reduced visibility.
Reduce this by taking shorter showers?
Water consumption will be reduced
What happens to the orbit of earth when the mass of the sun is reduced to 75000?
The orbit gets larger
What does the word mean stupor?
Stupor - A state in which you can't hear, see, or think clearly, to have reduced or suspended sensibility
Why is there a high tide on the side of the earth furthest from the sun?
It's obvious why there's a high tide on the side nearest the moon: the water is pulled by the moon's gravity. However, that pull is reduced the further you get from the moon, so on the far side, the water experiences a much reduced pull. That causes it to bulge outwards.
Is the projected benefits at age 70 reduced if you don't work after age 66?

What are the Differences between cost control and cost reduction?
Cost Control - a method whereby costs are managed and monitored to ensure they do not grow beyond the projected amount.Cost Reduction - a method whereby costs are reduced from the projected amount
A satellite is at an altitude of one of earth radius. How does the gravitational force on the satellite compare to the force if it were on the surface of earth?
Since the distance from the Earth's center is doubled, the force will be reduced by a factor of 4.
What is the projected result of converting 25 percent or less of crop and rangelands in the US to forests with native trees?
one of the projected result in converting 25% or less of crop and rangelands with native trees in the united states is that around 30% percent of food supply will be reduced. These days, we are very dependent on manufacture based food to fill our quota
The velocity of a body thrown vertically upward is reduced into half in one secondwhat is the maximum height attained by it?
velocity is found by dividing the distance with time. In a second the height traveled is found by multiplying the velocity by the time taken and then dividing the answer by two.
If a satellite is travelling in orbit around the earth and the gravitational force drops to nil what will happen to the satellite?
Without gravity, the satellite will travel in the same direction it was going when gravity went to nil. This is due to the object's momentum, and the satellite will go off into space. And if the gravitation were nil to begin with, there would have been no orbit in the first place. The question is problematic, since planets will always have gravity. Picture a ball on a string that is being whirled around by someone. If the string snaps, the ball continues to move in the direction it was going at the moment the string snapped. It flies off in a tangent, and the satellite will do the same thing if gravity is suddenly reduced to zero.

Satellite Internet: The New Way to Get Connected?
Satellite Internet service is the one high-speed Internet service that is available anywhere. As long as one has electricity and (in North America) a clear view of the southern sky, satellite broadband should be available. These broadband providers are generally specialized Satellite Broadband Providers. Unlike the first satellite internet services offered a few years back, neither a phone line nor a dial-up data modem is required for uploads. Satellite Internet service operates independently of telephone or cable networks. In order to have a satellite Internet connection in your home, you will need to have a satellite dish (antenna) attached to the roof of your home and a satellite modem connected to your home computer. After you select the right high-speed Internet plan, a certified installer will connect your computer to a satellite modem and link the modem to a satellite dish (antenna). The installer provides the satellite modem and the satellite dish. Once installed, the satellite dish sends and receives information (i.e., email, Web pages, files) over the Internet and delivers it to your computer through your satellite modem, giving you secure and fast high-speed Internet access. Performance speeds for residential download Satellite Broadband Internet are typically 500-1000 Kbps (Kilobytes per second) or about 10-20 times faster than a 56K modem. Upload speeds are generally 100 - 256 Kbps. Satellite Internet is not ideal for consumers who require highly responsive high-speed Internet service, such as that required for online games or stock trading. VPNs do not work well over satellite also. You may use a VPN, but you will likely experience reduced speeds by as much as 50–75 percent. You can restore your connection to full speed by simply disabling your VPN client when your session is over. Voice over IP and video streaming doesn't work well with satellite internet either, due to the latency issues. Installation for satellite Internet requires about $600.00 in specialized equipment and the proper installation of a small satellite dish with a clear view of the southern sky. Equipment can often be financed by the satellite Internet provider. Monthly, the costs usually run anywhere from $60.00 to $90.00, depending on service options and speed plus the cost of the equipment and in some case an activation fee of about $100. Some satellite Internet providers are now offering "cheap" satellite internet in the $40.00- $50.00 range. It is slower than regular Satellite broadband and conditions may apply. Be sure to ask about all available options. Some other tips when considering satellite internet: it is fully mobile, meaning you don't have to stay close to home to have access. It can be a perfect solution for an RV or the summer cabin. Be sure to evaluate all options before choosing a high-speed Internet service broadband provider.
