The table shows the gravitational force on an object measured on Earth and the Moon.
Location Gravitational Force on the Object (N)
Earth
490
81
Moon
Why is the gravitational force different in each location?
A
The Moon has more mass and gravity than Earth does.
B
E arth has less acceleration due to gravity than the Moon
C
Earth has more acceleration due to gravity than the Moon.
D.
The mass of the object is different on Earth than on the Moon

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.

Asatellite with an orbital period of exactly 24.0 h is always positioned over the same spot on earth. this is known as a geosynchronous orbit. television,communication, and weather satellites use geosynchronous orbits. at what distance would a satellite have to orbit earth in order to have a geosynchronous orbit?

In which item is energy stored in the form of gravitational potential energy? a. a slice of bread b. a compressed spring c. an apple on a tree d. a stretched bow string
