NASA's Mars Pathfinder mission, launched in 1996, put the first free-moving rover—called Sojourner—on the planet. ... Together, these missions have shown scientists that Mars is an active planet that is rich in the ingredients needed for life as we know it—water, organic carbon, and an energy source

Answer:

  • 0.0002012
  • 0.0002192

Explanation:

Using apparent = mass of liquid expelled/mass of liquid remaining × temp. rise

Mass expelled: 250-248.5=1.5g

Mass remaining =248.5g

Temp. rise= 60-30= 30ºc

= 1.5/248.5×30=0.0002012

Using real= apparent + cubic expansivty

Cubic= 3 × linear expansivty

= 3×0.000006=0.000018

0.0002012+0.000018=0.0002192

Increasing the two objects will cause the gravitational force between the objects to decrease.
ELEN [110]
This statement is false. Increasing the two objects' mass (I'm guessing) will actually increase their gravitational force. This is because of the equation:

F_g =  \frac{Gm_1m_2}{d^2}

If the distance was increased, then the statement would be true, but since you are increasing mass, which is proportional to the Force of Gravity, you are in fact, increasing the gravitational force between the two objects.

If you walk at an average speed of 5 km/h for 30 minutes, how
Inessa05 [86]

The distance that would be accumulated during the journey is 2.5 meters

The parameters given in the question are  written below;

average speed= 5 km/hr

time = 30 minutes

convert 30 minutes to hours

= 30/60

= 0.5 hours

Distance-= speed × time

= 5 × 0.5

= 2.5 meters

Hence the distance of the entire journey is 2.5 meters
