An object starts from rest and exhibits the motion represented by the graph. The object’s average velocity during the 3 second to 5 second time interval is approximately –
8.4 m/s
3.2 m/s
4.8 m/s
.0125 m/s
Answer:
8.4 m/s
Explanation:
Initial velocity of the object is 0 as it was at rest.
We need to find the object’s average velocity during the 3 second to 5 second.
We can see from the graph that from 3 s to 5 s, the graph is a straight line. If we take the slope we can find the average velocity during the 3 second to 5 second.
Displacement between 3 s to 5 s is :
D = 24.8 m - 8 m = 16.8 m
Time = 5 s - 3 s = 2 s
Now,
Average velocity,
[tex]v=\dfrac{\Delta y}{\Delta x}\\\\y=\dfrac{16.8\ m}{2\ m}\\\\y=8.4\ m[/tex]
So, the object’s average velocity during the 3 second to 5 second is 8.4 m/s.

What happens to the oxygen and carbon dioxide as we breathe
Answer:
Your lungs deliver oxygen and remove carbon dioxide from your blood in a process called gas exchange. Gas exchange happens in the capillaries surrounding the alveoli, where the oxygen that is breathed in enters the circulatory system and carbon dioxide in the blood is released to the lungs and then breathed out.

Which row in the chart below best
describes asexual reproduction?
3
2
1
4
Answer:
1
Explanation:
Asexual reproduction is the ability of an organism to produce offspring identical to themselves.
In asexual reproduction, the number of parents is one, and the generation of offspring is genetically identical to a single parent. Therefore, row (1) best describes asexual reproduction.
What is asexual reproduction?Asexual reproduction can be described as a mode of reproduction in which a new offspring is generated by a single parent. The new individuals generated are genetically and physically identical to each of their parents. Asexual reproduction can be defined as the mode of reproduction in which the production takes place of offspring by a single parent.
Asexual reproduction can be observed in both multicellular and unicellular organisms. This process does not include gamete fusion and no change in the number of chromosomes either. Asexual reproduction will inherit the same genes as the parent.
Characteristics of Asexual Reproduction are single parent, no fertilization takes place, occurs in a very short time, and grows rapidly. The offspring in asexual reproduction is genetically similar.

which contains the most amount of energy a glass of water at 20C or a glass of water at 80C. EXPLAIN ANSWER
Answer:
80C
Explanation:
As a substance gets hotter, or as a substance gets closer to the state of gas, the particles in the substance move faster, become more spread out and have more energy. This is why Gas has the most energy while solids have the least. Therefore, the hotter a substance is the more energy it has.
A glass of water at 80°C will have the most amount of energy
Explanation:
The temperature is defined as the degree of hotness and coldness of the object.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object, higher will be the value of temperature.The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.So, from this, we can conclude that glass with water at a higher temperature that is 80°C will have a higher amount of energy than a glass of water at 20°C.

a large office building is 1.07x10^2m long,31m wide. and 4.25x10^2m high. what id the volume?
If a large office building is 1.07 x 10^2 meters long, 31 meters wide. and 4.25 x 10^2 meters high, then the volume of the building would be 1409725 meters cube.
What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
As given in the problem we have to calculate the volume of a large office building having the dimensions of 1.07 x 10 ^2 meters long, 31 meters wide, and 4.25 x 10^2 meters high.
The volume of the office building = length × width × height
=107 × 31 × 425
=140925 meters cube
Thus, the volume of the building would be 140925 meters cube.

By mistake, a quart of oil was dumped into a swimming pool that measures 25.0 m by 30.0 m. The density of the oil was 0.750 g/cm3. Assuming the oil spread into a uniform, thin layer over the water, how thick was the oil slick?
The oil slick thick = 1.256 x 10⁻⁴ cm
Further explanationVolume is a derivative quantity derived from the length of the principal
The unit of volume can be expressed in liters or milliliters or cubic meters
The conversion is
1 cc = 1 cm3
1 dm = 1 Liter
1 L = 1.06 quart
so for 1 quart = 0.943 L
[tex]\tt 0.943~L=0.943\times 10^{-3}m^3[/tex]
Volume of oil dumped = volume of swimming pool
[tex]\tt 0.943\times 10^{-3}~m^3=25\times 30\times h(h=thick)\\\\h=\dfrac{0.943\times 10^{-3}}{750~m^2}=1.257\times 10^{-6}~m=\boxed{\bold{1.256\times 10^{-4}~cm}}[/tex]

If an egg is placed in a container of salt water, the mass of the egg will decrease because water will move out of the egg. What process does this represent?
Osmosis
Mitosis
Respiration
Fermentation
Answer:
osmosis. I
Explanation:
If an object/ cell is placed in a solution where the concentration is more or stronger than itself(hypertonic solution), it shrinks because water moves out of it, but if it is placed where the concentration of the surrounding solution is lesser than its concentration(hypotonic solution), it swells and can burst because water moves into it. So the mass of the egg will decrease because it is placed in an hypertonic solution (salt water) and the concentration of the salt water is stronger than its concentration

What is the molecular geometry of PBr3? A. trigonal pyramidal B. trigonal planar C. linear D....
The geometry of PBr₃ is trigonal pyramidal. Therefore, option A is correct.
Trigonal pyramidal geometry refers to the molecular geometry around a central atom in a molecule or ion where there are three bonded atoms and one lone pair of electrons. This geometry is commonly found in molecules with a central atom surrounded by three bonding pairs and one non-bonding pair of electrons.
The term "trigonal" refers to the arrangement of the three bonding pairs, which are positioned in a flat, triangular shape around the central atom. The term "pyramidal" indicates that the lone pair of electrons occupies the fourth position, giving the molecule a three-dimensional pyramid-like shape.
