Density is the characteristic property of a substance. It is the measure of mass of the substance
divided by its volume (density= mass/volume). Manipulate the given formula to
come up with the formula for the volume. Therefore, volume is equals to mass of
a substance divided by its density (Vol= mass/density). Given 12.6 g/ml as density
and 7.65 g mass, volume is equals to 0.60714 ml, since 1 ml = 1cm^3, volume is
equals to 0.60714 cm^3 then extract the cube root of the volume to get the
length of the cube in cm which is equal to 0.84677 cm.
Answer:
Personally I think, that the answer is B.
Explanation:
<span> <span> <span> <span> CLIMATE: The amount of water in the air and the temperature of an area are both part of an area’s climate. Moisture speeds up chemical weathering. Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates. Without temperature changes, ice wedging cannot occur. In very cold, dry areas, there is little weathering. </span> <span> SURFACE AREA<span>-
Most weathering occurs on exposed surfaces of rocks and minerals. The more surface area a rock has, the more quickly it will weather. When a block is cut into smaller pieces, it has more surface area. So, therefore, the smaller pieces of a rock will weather faster than a large block of rock</span> </span> <span> ROCK COMPOSITION<span>-
Some minerals resist weathering. Quartz is a mineral that weathers slowly. Rocks made up of minerals such as feldspar, calcite, and iron, weather more quickly.</span> </span> <span> Pollution speeds up weathering. Factories and cars release carbon dioxide and other gases into the air. These gases dissolve in the rainwater, causing acid rain <span>to form. Acid rain contains nitric and sulfuric acid, causing rocks and minerals to dissolve faster. </span> </span> </span> </span> </span>
Answer:
there are uncountable sun are there but sun is star therefore there are uncountable stars are there
Answer:
The kinetic energy when the film vault landed is 12744000J.
Explanation:
The kinetic energy is defined as:
(1)
Where m is the mass and v is the velocity.
By means of equation 1, the kinetic energy of the film vault when it landed can be determined
But 
Hence, the kinetic energy when the film vault landed is 12744000J.
