If you mass 35kg on earth what will your mass be on the moon where gravity is 1/6 that of earths. PLZZZZ HElP NEED ASAP

abruzzese [7]

Answer:

Mass will be same on moon as on Earth but weight will be one-sixth of Earth.

Explanation:

Mass of a body doesn't depend on gravity. Mass is a constant quantity. So, mass on moon will be same as mass on Earth.

But, the weight of a body depends on gravity as weight is given as:

$\textrm{Weight}=\textrm{mass}\times \textrm{acceleration due to gravity}$

Therefore, if $g$ is acceleration due to gravity on Earth, then weight on Earth is, $W_{E}=mg$

Now, gravity on moon is one-sixth of Earth. So, $g_{moon}=\frac{1}{6}g$

Therefore, weight of the body on moon is, $W_{moon}=mg_{moon}=m\times \frac{1}{6}g=\frac{1}{6}mg=\frac{1}{6}W_{E}$

Therefore, a body has same mass both on moon and Earth but weight on moon is one-sixth of the weight on Earth.

On a certain map, every 3 cm represents 6 km on earth surface. Which ratio represents the scale of the map, which shows how the

damaskus [11]

Answer:

1 : 2 cm/km or $\frac{1}{2} \, \frac{cm}{km}$

One cm represents 2 km.

Explanation:

If 3 cm represents 6 km on the earth, the ratio to consider is: 3 : 6 cm/km which is the same as:

1 : 2 cm/km or $\frac{1}{2} \, \frac{cm}{km}$

One cm represents 2 km.
