How did scientists boost the spacecraft juno on its way to jupiter, it overcome the gravitonal pull of the sun?

With the help of gravitational slingshot.

Explanation:

The scientists utilized the gravitational slingshot to boost the spacecraft Juno on its way to Jupiter, and at the same time assisting it to get rid of the Sun's gravitational pull. The Juno refers to the NASA space probe, which is orbiting around Jupiter. The Juno was launched in 2011 and comprises the maximum speed of 265000 kilometers in an hour.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
