1. Find the density of an object that has a mass of 8.2 grams and a volume of 3 cc.
satela [25.4K]

The actual formula for volume for a cube is the length multiplied by the width and then multiplied by the height. Since all three measurements are the same, the formula results in the measurement of one side cubed. For the example, 5^3 is 125 cm^3. Multiply the volume by the known density, which is the mass per volume.

How many moles of sulfur are in 80 grams of sulfur?
Norma-Jean [14]

Answer:

2.5 moles

Explanation:

Number of moles = MassMolar mass

= 80⋅g32.06⋅g⋅mol−1 = ??mol

Note that sulfur likely exists in its elemental state as S8. I am perfectly justified in treating sulfur as S. The number of sulfur atoms is the same in each case.

Write one paragraph to explain what circuler motion is?
ZanzabumX [31]

Answer:

When a body moves in a circle with constant speed , it is said to be in uniform circular motion .

Explanation:

  • When an object moves in a circular path , its direction changes at each point .
  • This change in direction result in change of velocity (velocity is vector quantity which changes if direction of the object change) .However speed do not change (it is scalar quantity , not affected by Direction)
  • The Change in velocity produce acceleration ( a = v - u)
  • Hence The object always produce acceleration in uniform circular motion .So, Some force (centripetal force) is needed to keep the object in circular motion.

A scientist is studying the effect of climate change on a population of fur seals living on an island off the coast of Alaska. F
solniwko [45]

Answer:

A

Explanation:

The only factor that would not decrease the carrying capacity of the fur seal's environment is the population of predators.

<em>The carrying capacity is defined as the maximum number of individuals of a species an environment can sustain based on the resources available. Hence,   only a fluctuation in the resources available in the environment of the fur seal can affect the carrying capacity. </em>

<u>Pollution </u>and <u>destruction of the habitat of the fur seal</u> would limit the resources available to the animals and as such, limit the carrying capacity. A <u>fluctuation in the population of prey available</u> for the population of fur seals would also affect the carrying capacity.

The only factor that has no bearing on the carrying capacity of the fur seal's environment is the population of predators. Predators have the capacity to reduce the population of fur seals but not affect the carrying capacity for fur seals.

The correct option is, therefore, A.
