Answer:

This causes the object to move in an oblique motion.

Explanation:

Oblique movement occurs when an object is thrown and begins its movement at a certain angle to the horizontal. In this type of throw, the object performs two simultaneous movements, while performing a vertical movement, rising and falling, also moving horizontally.

The analysis of the oblique throw must be made taking into account the movement executed vertically (y axis) and the horizontal movement (x axis). Regarding the movement in the y axis, the concern will be the determination of the maximum height reached by the body, because of the action of gravity in this axis the movement will be uniformly varied. X-axis motion analyzes will determine the horizontal range of the throw, ie the distance between the starting and finishing points. Horizontally, the movement will be rectilinear and uniform.

Ad libitum [116K]

Answer:

A. They cycle elements through the biotic and abiotic components of an ecosystem.

Explanation:

Chemical elements such as nitrogen, carbon, phosphorus etc. moves between the living and non-living parts of an ecosystem in the biosphere. The cycle of these elements between these counterparts (abiotic and biotic) is referred to as the BIOGEOCHEMICAL CYCLE.

Firstly, the biotic components of an ecosystem refers to the living organisms such as plants, animals, microbes etc while the abiotic components are the non-living parts such as soil, water etc. Therefore, according to the description given in the options, option A describes what a BIOGEOCHEMICAL CYCLE best.

The unit cells can be represented by tennis balls arranged in various configurations in a box. For the FCC structure, (a) determ

-Dominant- [34]

Based on the diagram shown in the attached file

R = Radius of the sphere

a = Lattice constant

Using pythagoras theorem for the right angled triangle in figure 2

(4R)^2 = a^2 + a^2

16(R^2) = 2(a)^2

Solving the above equation

a=2R√2

To prove that the Atomic Packing factor is 0.74

Let the volume of atom in a unit cell be Vs

Total unit cell volume, Vc

Vc = a^3

Vc =(2R√2)^3

Vc=16R^3 √2 =22.63R^3

Since there are 4 atoms in the FCC unit cell

Vs=4*(4/3 πR^3)

Vs=5.33 πR^3

APF=(5.33 πR^3)/(22.63R^3 )

APF=0.74

Answer:

Put simply, Asexual reproduction is reproduction without the use of gametes or the number of chromosomes being changed. So they are genetically identical creatures. Some animals include wasps, lizards, sharks, turkeys, and sea urchins.

Sexual reproduction includes chromosomes and gametes being fused, creating genetically different offspring. Examples of creatures that reproduce sexually are humans, chickens, cow, pigs, etc.

How does increasing the concentration of a nonvolatile solute in water affect the following properties:Vapor pressure: Decreases

PIT_PIT [208]

Answer: Osmotic pressure : increases

Explanation:

Osmotic pressure is the minimum pressure which is applied to a solution to prevent the flow of solvent across a semipermeable membrane

$\pi =CRT$

$\pi$ = osmotic pressure

C= concentration in Molarity (number of moles of solute dissolved per liter of the solution)

R= solution constant

T= temperature

Thus as osmotic pressure is directly proportional top concentration, osmotic pressure will increase on increasing the concentration of a nonvolatile solute in water.
