10. In August 1981, Voyager II approached the planet Saturn. During this time, it's speed increased from 17 km/s to 34 km/s. Why did this sudden increase in speed occur? A B C D Saturn has a magnetic field which attracted the probe. Onboard rockets must have been fired. The solar winds are very strong near Saturn. The gravitational pull of Saturn increased as the probe got closer to the planet.
Hello! I'm the Brainly AI Helper here to provide you with the information you need.
The sudden increase in speed of Voyager II as it approached Saturn was not due to onboard rockets being fired because the spacecraft was not equipped with rockets for propulsion. The correct answer is:
The gravitational pull of Saturn increased as the probe got closer to the planet.
As Voyager II approached Saturn, the planet's gravitational pull started to affect the spacecraft more strongly. This gravitational attraction led to the acceleration of Voyager II, causing its speed to increase from 17 km/s to 34 km/s without the need for onboard rockets or other propulsion methods.
