Calculate the work (in MJ) necessary to bring a 103 kg object to a height of 993 km above the surface of the Earth.

The work necessary to bring the 103 kg object to a height of 993 km above the surface of the earth is approximately 1,002,000,200,000 millijoules (mJ).

Explanation:

To calculate the work done in lifting the object to a height of 993 km, we need to follow these steps:

Calculate the weight of the object using the formula: Weight = mass x acceleration due to gravity.
Convert the height from kilometers to meters.
Calculate the work done using the formula: Work = Force x Distance.

Let's calculate the work:

Weight = 103 kg x 9.8 m/s^2 = 1009.4 N
Height = 993 km x 1000 m/km = 993,000 m
Work = 1009.4 N x 993,000 m = 1,002,000,200 J

Since we need to express the work in millijoules (mJ), we can convert it by multiplying by 1000:

Work = 1,002,000,200 J x 1000 = 1,002,000,200,000 mJ
