Hey guys...please help me with both b) and c) in this question.

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.

Answer:

Brown dwarf has the lowest temperature

Answer:

(u mean theory* i think)

Grounded theory differs from either qualitative content analysis or thematic analysis because it has its own distinctive set of procedures, including theoretical sampling and open coding. In contrast, the procedures in the other two are not specified at the same level of detail.

The car's rate of change of position is decreasing. The car is moving but its rate of position increase is coming down. The car will eventually come to a brief stop and begin traveling backward.

Answer:

Archimedes' Principle

Explanation:

Its because Archimedes' Principle states "that the buoyant force on an object is equal to the weight of the fluid displaced by the object.... If you want to know the buoyant force on an object, you only need to determine the weight of the fluid displaced by the object."

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).

Cant conduct heat or electricity?

Answer:

add the Resistance

2(100)= 200

2) 200 ohms

If two 100 ohms resistors are placed in series, their total resistance will be 200 ohms

When two or more resistors are connected end to end consecutively , they are said to be connected in series combination .Total resistance in  series combination is calculated as the algebraic sum of individual resistances

General formula = R (equivalent ) = R1 + R2 + R3 + .......

let R1 = 100 ohms

R2 = 100 ohms

R(equivalent resistance in series combination )= R1 + R2

R = 100 + 100

R = 200 ohms

If two 100 ohms resistors are placed in series, their total resistance will be b) 200 ohms

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.

Answer:

It is A. Open Circuit.

Explanation:

Filament heats up and produces the light. If the filament breaks, the current does not flow and the circuit will be open. The ammeter will reach zero when this happens.

Answer:

12 (Magnesium- Mg)

Explanation:

Looking at the four numbers, we have:

Magnesium, Silicon, Sulfur, and Chlorine.

We can eliminate two of the answers immediately just by looking at the periodic table.

Sulfur and Chlorine are on the nonmetal side of the periodic table. So that's definitely not it. That leaves Magnesium and Silicon.

Silicon is a Metalloid. Magnesium is an Alkaline earth Metal.

Metaloids are elements that have a mix of both metal and nonmetal properties (luster, how it feels, etc.). Since it's a MIX and Magnesium is just straight METAL-

We can say Magnesium has the most metallic properties.

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.

Answer:

The coastal zone is not a stable and constant environment, but a dynamic place that can change rapidly in response to natural processes such as seasonal weather patterns. Waves, winds, currents, tides and storms are the major forces on the coast.

Explanation:

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

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.

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

Answer:

(a) k = 80 N/m   (b) x = 75 cm

Explanation:

The question says that, "A spring is elongated 30 centimeters when we exert a force of 24 N on it a) calculate the value of the spring constant b) calculate the elongation of the spring when applying a force of 60 N"

Given that,

Force exerted on the spring, F = 24 N

Elongation in the spring, k = 30 cm =0.3 m

(a) We know that, the force on the spring is given by :

F = kx

Where

k is spring constant

So,

[tex]k=\dfrac{F}{x}\\\\k=\dfrac{24}{0.3}\\\\k=80\ N/m[/tex]

(b) When F = 60 N,

[tex]x=\dfrac{F}{k}\\\\x=\dfrac{60}{80}\\\\x=0.75\ m\\\\x=75\ cm[/tex]

Hence, this is the required solution.
