A rectangular gasoline tank can hold 50.0 kg of gasoline when full. What is the depth of the tank if it is 0.500-m wide by 0.900
sweet-ann [11.9K]

Answer:

0.16 m

Explanation:

A rectangular gasoline tank can hold 50.0 kg of gasoline when full, and the density of gasoline is 6.8 × 10² kg/m³. We can find the volume occupied by the gasoline (volume of the tank).

50.0 kg × (1 m³/6.8 × 10² kg) = 0.074 m³

The volume of the rectangular tank is:

volume = width × length × depth

depth = volume / width × length

depth = 0.074 m³ / 0.500 m × 0.900 m

depth = 0.16 m

Which physical property is used to test the purity of metal ?
dimulka [17.4K]

The physical and chemical properties of metal can differ between the elements but if we try and generalize.


Physical properties are that they are hard, dense, shiny, malleable (can be bent), ductile (can be pulled into wires), a good conductor of heat and have high melting points meaning that they are solid at room temperature


Their chemical properties include being good electrical conductors, they make metallic bonds (ionic bonds with non-metals) and their atoms are arranged in a lattice. They release hydrogen when reacted with acids and are usually cations (positive ions).

The small and large pistons of a hydraulic press
Vsevolod [243]

Answer:

1600 N

Explanation:

pascals principle says..

\frac{A_{out}}{A_{in}} =  \frac{F_{out}}{F_{in}} \\

so lets do

\frac{2}{4} = \frac{x}{3200}

so multiply one half (2/4 simplified) by 3200

1600 is equal to x

1600 N
