6. An excited dog runs full-speed toward his owner who has just returned home from
school. If he runs north along their driveway for a distance of 45 m and takes 5.2 s to get
there, what is his average velocity?
Please answer in comments with work !!:)
Answer:
v = 8.65 m/s
Explanation:
Given that,
Distance covered by the doge, d = 45 m
Time taken, t = 5.2 s
We need to find its average speed. The total distance covered divided by the total time taken is called the average speed of an object. So,
[tex]v=\dfrac{45\ m}{5.2\ s}\\\\=8.65\ m/s[/tex]
So, the average speed is 8.65 m/s.

I'm contrast to Venus the coldest temperature yet measured on the surface of any body in the solar system is -235C
Answer:
Explanation:
I don't get what the relation here is. Venus is the hottest planet in our solar system. And yes, it's hotter than mercury despite mercury being closer to the sun. And your question talks about the coldest temperature measured which is -235 degrees Celsius. That surely isn't measured on Venus. I'm only wondering what Venus has got to go with cold and what exactly your question is

Comparing Cells
i need to know a few things about the primary function and organelles present in..
protists cells
fungus cells
plant cells
and, animal cells
Answer:
Protists cells: ribosomes, mitochondria, and chloroplasts.
Fungus cells: cell walls, nuclei, mitochondria, endoplasmic reticulum, Golgi apparatus, endosomal vacuoles, various types of vesicles, and peroxisomes.
Plant cells: chloroplast, cell wall, plastids, and a large central vacuole.
Animal cells: nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles.
Answer:
1) Ribosomes: Are the organelles responsible for synthesizing all the proteins the protist will need
Mitochondria: which are the organelles responsible for turning food into energy the cell can use
Chloroplasts, which are the organelles that are able to capture sunlight
____________________________________________________________
2) Mitochondria: Developmental and morphogenetic switches such as hyphal differentiation and biofilm formation, adaptation to stress, cell wall biosynthesis and structure.
Endoplasmic reticulum: harbors several of the enzymes involved in the biosynthesis of ergosterol, an essential membrane component
Golgi apparatus: performs crucial functions in the sorting and processing of proteins destined for secretion
____________________________________________________________
3) Chloroplast: Allow plants to capture the energy of the Sun in energy-rich molecules and carries out the process of Photosynthesis.
Cell wall: The cell wall surrounds the plasma membrane of plant cells, providing structure and protects the plant from mechanical and osmotic stress.
Plastids: responsible for manufacturing and storing of food. These often contain pigments that are used in photosynthesis
Vacuole: Simply helps maintain water balance, usually large and takes up most of the space in a plant cell.
____________________________________________________________
4) Nucleus: Controls and monitors the activities of the cell and carries the genes, structures that contain the hereditary information for their offspring.
Mitochondria: Generates most of the chemical energy needed to power the cell's biochemical reactions.
Endoplasmic reticulum: Serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins.
Golgi apparatus: Helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
Vesicle: Transport vesicles help move materials, such as proteins and other molecules, from one part of a cell to another
Vacuole: Are generally small and help dispose waste products in the cell.
Ribosomes: Link together specific amino acids to form polypeptides and they export these to the cytoplasm.

Explanation:
When the forces acting on a stationary object are unbalanced, the object will
A. remain stationary
B. begin moving and speed up
C. remain moving at a constant speed
D. No effect
Answer:
B
Explanation:
Well it is certainly not no effect. Something has to happen. Not D.
If the balances are unbalanced it means that there is a force left over that can cause an acceleration. The speed is not constant when there is an acceleration. Not C
Unbalanced forces mean that there has to be something happening. Unless the friction cannot be overcome, there will be motion. Not A. But it is your second best answer if there is friction.
The answer I think you are intended to give is B.
A car with a mass of 2000 kg accelerates at 6 m/s'at a green light. What is the car's force?
Answer:
Car's force is 12000 N.
Explanation:
→ Force = Mass × Acceleration
→ Force = 2000 kg × 6 m/s²
→ Force = 12000 NA negative charge of -0.00040 C and a positive charge of 0.00092 C are separated by 0.4 m. What is the force between the two charges?
Answer:
20654 N
Explanation:
Applying
F = kqq'/r²........... equation 1
Where F = Force between the charge, q = First charge, q' = second charge, r = distance betweeen the charge, k = coulomb's constant.
From the question,
Given: q = -0.0004 C, q' = 0.00092 C, r = 0.4 m
Constanr: k = 8.98×10⁹ Nm²/C²
Substitute these values into equation 1
F = ( -0.0004×0.00092×8.98×10⁹)/(0.4²)
F = (3.30464×10³)/0.16
F = (3304.64)/0.16
F = 20654 N
Hence the force between the charges is 20654 N

Biology of awerness. Based on information in the articale, what is the most likely reason all organisms adapted to havea the trait of awarenes
Answer:
Awareness was selected because it was beneficial to organisms in particular environments.
Explanation:
Based on the article, natural selection is a phenomenon that recognizes and allows traits that are useful to an organism and that would be favorable for it to be passed from one generation to another.
Natural selection marked awareness as a useful trait that would be beneficial for organisms because it helped them adapt well to the particular environments that they found themselves. For example, this ability helped an organism to be able to recognize where it could get food and light in its environment.
What is the rule you would write describing how light reflects off a mirror?
Answer: The angle of incidence equals the ray of reflection. So this law states that any ray of light that strikes an object will reflect off the object such that the striking or incident angle is identical to the reflecting angle (as measured from the normal).

If the work required to speed up a car from 11 km/h to 21 km/h is 6.0×103 J , what would be the work required to increase the car’s speed from 21 km/h to 33 km/h
Explanation:
We need convert the velocities first to m/s and we get the following:
v2 = 21 km/hr = 5.8 m/s
v1 = 11 km/hr = 3.1 m/s
We need to find the mass of the car also for later use do using the work-energy theorem:
[tex]delta \: w = \frac{1}{2} m(v \frac{2}{2} - v\frac{2}{1} )[/tex]
6.0x10^3 J = (0.5) m [(5.8)^2 - (3.1)^2]
or
m = 499.4 kg
Now we determine work needed delta W to change its velocity from 21 km/hr to 33 km/hr
v2 = 33 km/hr = 9.2 m/s
v1 = 21 km/hr = 5.8 m/s
delta W = (0.5)(499.4)[(9.2)^2 - (5.8)^2]
= 1.3 x 10^4 J
If you put 3.27 moles of an ideal

what pressure will it create?
(Make sure to put P, V, and T
in the right units.)
(Unit = Pa)
Answer:
1.65 atm
Explanation:
Applying,
PV = nRT....................... Equation 1
Where P = Pressure, V = Volume, n = number of moles, R = malar gas constant, T = Temperature.
Make P the subject of the equation
P = nRT/V..................... Equation 2
From the question,
Given: n = 3.27 moles, V = 50.0 L, T = 35 °C = (273+35) = 308K
Constant: R = 0.082L.atm/K.mol
Substitute these values into equation 2
P = 3.27(0.082)(308)/(50)
P = 1.65 atm
