1. What is the relationship between seasons in the northern hemisphere and southern hemisphere? Explain.

2. Identify the seasons that are represented in the northern hemisphere and in the southern hemisphere. Explain.

Answer:

a= 1 m/s^2

Explanation:

Average acceleration can be found by dividing the change in velocity by the time.

a= ΔV/t

The change in velocity is the difference of the final velocity and initial velocity.

ΔV= final velocity - initial velocity

The final velocity is 30 m/s and the initial velocity is 25 m/s

ΔV= 30 m/s- 25 m/s

ΔV= 5 m/s

The time is 5 seconds.

Now we know the two values.

ΔV= 5 m/s

t= 5 s

Substitute the values into the formula.

a= 5 m/s / 5 s

Divide.

a= 1 m/s/s

a= 1 m/s^2

The average acceleration of the car is 1 meter per second squared.

The acceleration of the car with the mass of 1200kg and a force of 11 × 10³N is 9.17m/s²

Answer:

a) τ = -518 lb-inch , b)  d = 0 inch

Explanation:

a) The moment of a force is given by

         τ = F x r

The bold letters indicate vectors, we can solve the magnitude of this expression with

        τ = F r sin θ

and the angle by the right hand rule.

In general, the applied force is perpendicular to the rubber and in such a direction that the moment is opposite to the movement, therefore the angle is 270 = -90º and the sin 270 = -1

        τ = -F r

To perform a complete calculation, the radius of the rubber is needed, for example for a small car the radius is about 14 inch = 1,167 feet

       τ = -37 14

       τ = -518 lb-inch

The point o is assumed to be the center of the wheel, the negative sign indicates that the moment is clockwise

b) As the rubber is a circle and the force is perpendicular, the vector product gives an emoticon perpendicular to the rubber, so that this value decreases to zero we must reduce the application point (distance), that is, the distance must be zero.

            d = 0 inch

Answer:

Output varies

Explanation:

Here the outputs of gallons of gasoline and flight fuel is mentioned of two refineries namely Refinery EM and Refinery CG. The output has been mentioned with respect to one barrel of crude oil. So, one barrel of crude is used by both the refineries.

So, here the output (gallons of gasoline and flight fuel) varies while the input (one barrel of crude oil) remains constant.

The range of the projectile is 60 meters

Explanation:

To determine the range/distance of the projectile, the formula for velocity is used;

velocity = distance/time

where velocity is 15 m/s

time is 4 seconds

distance is unknown

From the formula above, distance is made the subject and thus

distance = velocity × time

distance = 15 × 4

distance = 60 m

The range of the projectile is 60 meters

Answer:

Explanation:

the process is given

Answer:

9 s.

Explanation:

The following data were obtained from the question:

Time (t) taken to reach the maximum height = 4.5 s

Time of flight (T) =?

The time of flight (T) is simply defined as the total time spent by the ball in the air. Mathematically, it defined as twice the time taken (t) to reach the maximum height i.e

T = 2t

With the above formula, we can obtain the time of flight as follow:

Time (t) taken to reach the maximum height = 4.5 s

Time of flight (T) =?

T = 2t

T = 2 × 4.5

T = 9 s

Thus, the time of flight of the ball is 9 s.

Answer:

Lindsay is planning a flight from St. Catherines to Hamilton, which lies due west of St. Catharines. Her aircraft flies at a speed of 200 km/h in still air. A wind of 50.0 km/h is blowing from [W 60.0� N]. In what direction must she aim the airplane to fly directly to Hamilton?

------------

It's a triangle problem.

The long side is the 200 km/hr, at an angle to be determined.

-----

1 side is 50 km/hr at an angle of -60 degs or 300 degs.

The 3rd side's length is not known, but it's at an angle of 180 degs (along the x-axis).

Lindsay has to fly this plane towards this direction [W 12.5° S] to get to Hamilton.

From this question, the plane is still up in the air.

We have wind blowing in [W 60° N ]

To solve the problem we have to make use of the sine rule

[tex]\frac{SinA}{a}=\frac{SinB}{b} =\frac{SinC}{c}[/tex]

We put the values in the equation, we have:

50/Sinθ = 200/sin60°

The next step is to cross multiply

50 x sin60° = 200Sinθ

50 x 0.8660 = 200sinθ

We make Sin θ the subject

Sine θ = 43.30/200

sine θ = 0.2165

we find the value of θ

θ = sine⁻¹(0.2165)

θ = 12.50

So Lindsay has to fly this plane towards this direction

[W 12.5° S]

A student wants to test if a bean plant will grow taller under green light than under sunlight. Select from the drop-down menu the correct step of the scientific method that each statement describes. Two identical bean plants are grown next to each other. They receive the same amount of water and sunlight. One plant is covered with a green, light-filtering plastic cover, and the other with a clear plastic cover. Measurements of the bean plants’ heights are recorded every day for two weeks. The student writes a lab report detailing the experimental procedure and results. The bean plant grown under the green filter will grow taller than the bean plant grown under unfiltered sunlight. Green light makes plants grow taller. The measurements show that the plant grown in natural sunlight grew taller than the green-filtered plant. So green light does not make plants grow taller. Plants are colored green, so maybe they grow more in green light.

Explanation:

1. An experiment is a procedure carried to test a hypothesis in order to support, reject or confirm the hypothesis. The steps below are for an experiment to whether bean plants grow taller under green light or sunlight.

Answer:

The length of the image of the pole is 4/3 m

Explanation:

The given parameters are;

The length of the Pole = 4 m

The type of mirror = Convex mirror

The distance of the pole from the mirror = 2 m

The mirror formula for convex mirrors is presented here as follows;

[tex]\dfrac{1}{U} - \dfrac{1}{V} = - \dfrac{1}{F}[/tex]

Where;

U = The object (pole) distance from the mirror = 2 m

V = The image of the objects (pole) distance from the mirror

The focal length of the mirror

Therefore, by substitution, we have;

[tex]\dfrac{1}{2} - \dfrac{1}{V} = - \dfrac{1}{1}[/tex]

[tex]\dfrac{1}{2} + 1 = \dfrac{1}{V}[/tex]

[tex]\dfrac{1}{V} = \dfrac{1}{2} + 1 = \dfrac{3}{2}[/tex]

[tex]V = \dfrac{2}{3}[/tex]

We have;

[tex]Magnification = \dfrac{Image \ height}{Object \ height } = \dfrac{Length \ of \ the \ Image \ of \ the \ Pole}{Length \ of \ the \ of \ the \ Pole } =\dfrac{-V}{U}[/tex]

Which by substitution gives;

[tex]Magnification = \dfrac{Length \ of \ the \ Image \ of \ the \ Pole}{4} =\dfrac{-\dfrac{2}{3} }{2} = \dfrac{2}{6}[/tex]

[tex]{Length \ of \ the \ Image \ of \ the \ Pole}{} = 4 \times \dfrac{2}{6} = \dfrac{4}{3}[/tex]

The length of the image of the pole = 4/3 m

From the given options, the end product of mitosis is Two identical nuclei (option b)

Mitosis is a fundamental cellular process that occurs in somatic (non-reproductive) cells, aiming to create two genetically identical daughter cells from one parent cell. It consists of several stages: prophase, metaphase, anaphase, and telophase.

During prophase, the chromatin (a combination of DNA and proteins) condenses into visible chromosomes, and the nuclear membrane disintegrates. In the subsequent stage, metaphase, the chromosomes align at the cell's equator, ensuring each daughter cell receives an equal number of chromosomes.

Next comes anaphase, where the paired chromosomes are pulled apart and move towards opposite poles of the cell. The final phase, telophase, involves the formation of two separate nuclei around the separated chromosomes.

At the end of mitosis, the single parent cell has divided into two genetically identical daughter cells, each containing a complete set of chromosomes. These daughter cells are fully functional and capable of carrying out their specific tasks within the organism.

So, the correct Answer: B. Two identical nuclei.
