On Earth, gravity increases the speed of a falling object by about 9.8 m/s
every second that it falls.

In 0.4 second, its speed increases by (0.4 x 9.8) = 3.92 m/s.

If it just rolled off of the shelf at the beginning of that 0.4 second, then it
started from zero speed, and its speed after 0.4 second is 3.92 m/s.

Its velocity is 3.92 m/s downward.

Elan Coil [88]
<span>The heavier the body is, the stronger its gravitational pull. Example, the Milky Way Galaxy has a gravitational pull because of the heavenly bodies such as stars and planets are surrounding it. A strong force is exerted if the mass of another body is bigger than the other body.</span>

Which of the following statements best explains why liquid water is NOT found on Jupiter?
agasfer [191]

Answer:

The planet lacks a solid surface and the temperature is too low

Explanation:

Jupiter does not have solid surface as it is made up of swirling gases, mainly hydrogen(90%) and helium(~10%). The swirl comes from massive wind with speed of 335 miles/hour. The temperature in cloud of Jupiter is 145°C which is too low for water to remain in liquid state as the temperature range for liquid water is 0°C to 100°C.
