If the density of a metal bar is 3.47 g/mL and volume is 30 mL, calculate the mass of the metal bar in grams (g). Show the steps

Hitman42 [59]

Answer:

$m=104.1g$

Explanation:

Hello,

In this case, considering that the density is considered as the quotient of the mass and volume:

$\rho =\frac{m}{V}$

We can easily compute the mass by solving for it as follows:

$m=V*\rho =30 mL*3.47g/mL\\\\m=104.1g$

Best regards.

Look at the images of Mars below. choose three features from the images and explain why they provide evidence thatt there is or

asambeis [7]

Answer:

Spot (4) Has evidence that there were waves here at some point. It looks as if the sand/surface debris was moved back and forth, creating this pattern in the sand. Spots (5) and (7) show evidence of water erosion. The smooth edges of both hills mean that water once flowed through that area, carrying little pebbles and rocks that gradually shaped and smoothed those mounds. An example for this would be how there are smooth areas in the Grand Canyon where scientists have concluded that some, if not all, of the Grand Canyon was formed by flowing water. "Rapid uplift, cracking, and surface drainage of receding floodwaters provide both the path and the necessary volume of water to quickly carve out Grand Canyon," says scholars on icr.org.

Explanation:

Water Erosion exists.
