twenty-four

The four satellites are needed to determine the location of an object using a GPS receiver.

Option: B

Explanation:

A GPS receiver specifically calculates the different speed of light (299,792 km / s) variations in the signals arriving from 4 or more satellites to determine the location of Longitude, Latitude and Highness.

There is requirement of four satellites, since each satellite data brings around the satellite in a sphere. You can limit the considerations down to a single point by programming the crossings. The collision of three satellites positions you on two possible points. The last satellite shows you exactly where you are.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
