Answer: object is not moving
Explanation:
Which phase of cell division is shown?
Exploring meiosis.
A. metaphase
B. prophase
C. anaphase
D. telophase
Answer:
Anaphase
Explanation:
This is because the spindle fibres have shortened and is pulling the chromatids towards the poles of the cell. The chromatids have also separated.
The cell division which is shown in the picture is anaphase. The correct option is C.
What are the phases of meiosis?Meiosis is divided into two main phases, each with its own set of subphases:
1 Meiosis I:
a. Prophase I: This is the longest and most complex phase of meiosis. During this phase, homologous chromosomes pair up and form bivalents, and crossing over occurs between the homologous chromosomes. The nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.
b. Metaphase I: During this phase, the homologous chromosomes line up along the metaphase plate, with one chromosome from each homologous pair facing each pole of the cell.
c. Anaphase I: During this phase, the spindle fibers contract and pull the homologous chromosomes towards opposite poles of the cell.
d. Telophase I: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in two daughter cells.
2. Meiosis II:
a. Prophase II: During this phase, the nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.
b. Metaphase II: During this phase, the chromosomes line up along the metaphase plate, with sister chromatids facing opposite poles of the cell.
c. Anaphase II: During this phase, the spindle fibers contract and pull the sister chromatids towards opposite poles of the cell.
d. Telophase II: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in four haploid daughter cells.
Meiosis involves two rounds of chromosome segregation, resulting in four haploid daughter cells that are genetically distinct from the parent cell.
Therefore, The correct option is C i.e anaphase.

The diagram below shows some waves traveling along a rope.
State the type of waves travelling on the rope.
Explain how you can tell. *
(2 points)
-- Well first of all, the waves are transverse waves. The fibers in the rope, and the hand that generates the waves, are moving up and down, but the wave is moving to the right, towards the wall. These directions are perpendicular.
-- Later on, after the waves reflect from the wall and travel back toward the hand, there are going to be standing waves on the rope. But this is probably beyond the scope of the question.

why does a heater having low resistance heating coils get heated more?
Answer:
Explanation:
That electrical energy will be dissipated in the form of heat, heating up the wire in the process. This heating is called Joule heating (James Prescott Joule) or ohmic heating or resistive heating. Which tells us that lower resistance (R) will produce higher current. Therefore lower resistance produces more heat.

Centripetal acceleration depends directly on the square of the object's speed and inversely on
the radius of the circle.
A-True
B-False
Answer:
True.
Explanation:
The formula for the centripetal acceleration of an object can be calculated by the formula as follows :
[tex]a_c=\dfrac{v^2}{r}[/tex]
Where
v is the speed of an object
r is the radius of the circle
It means, the centripetal acceleration depends directly on the square of the object's speed and inversely on the radius of the circle. Hence, the given statement is true.

A high fountain of water is located at the center of a circular pool. Not wishing to get his feet wet, a student walks around the pool and measures its circumference to be 15m. Next, the student stands at the edge of the pool and uses a protractor to gauge the angle of elevation at the bottom of the fountain to be 55°. How high is the fountain?
Answer:
The fountain is 3.43 m high.
Explanation:
Circumference of the pool = 15 m.
C = 2[tex]\pi[/tex]r
where C is the circumference and r its radius.
r = [tex]\frac{C}{2\pi }[/tex]
= [tex]\frac{15}{2(\frac{22}{7}) }[/tex]
r = 2.3864
radius of the pool = 2.40 m
So that the height of the fountain, h, can be determined by applying trigonometric function.
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
Tan 55 = [tex]\frac{h}{2.4}[/tex]
h = Tan 55 x 2.4
= 1.4282 x 2.4
= 3.4277
h = 3.43 m
The height of the fountain is 3.43 m.

Two by four about a three the espn by the Xbox 360 by the one two three and the logical by the fire the iso cohedron uh the Isosceles and the diameter by the three by four?
Answer:
divided by 2 plus one entity_secured_pace_nun_box 9 divided by oee burned akward potion tri tour all around divided by 3 divided by 4
Explanation:
So the first few words in this statement talks about two and four being equal to around three therefore giving you "divided by 2" as you need to divide the four by 2 and add one to get 3. The next statement "the espn by the Xbox 360", espn can be deemed as a secured entity that paces around a nun therefore giving you entity_secured_pace_nun and since this is being multiplied by a box and by 360, you apply the "Improve Rule of Baseless Base". This rule allows you to get entity_secured_pace_nun_box_9. Box comes from multiplying what we have with box and the 9 comes from adding 3+6+0. Since a logical fire is present in this equation, you burn the letters in "two three" that have no protection, these letters are t,w,t,h, and r. Next, you can take cohedron that sounds like couldron and brew yourself an akward potion with the tri sided isosceles. The diameter can be seen as a round up rule that allows you to regroup the answer you have so far. The "by the three by four" can easily be translate from the "Baseless Base Rule Compilation" giving you divided by 3 and divided by 4. That is why the answer is divided by 2 plus one entity_secured_pace_nun_box 9 divided by oee burned akward potion tri tour all around divided by 3 divided by 4. No need to thank me.

what happens to balloon filled with air when it goes very high attitude from surface of earth why
Answer:
The balloon will continue to expand and eventually burst.
Explanation:
Simply, the reason for this is because the density of the atmosphere decreases gradually as you increase in altitude closer to space. This means that the air on the outside of the balloon can't provide enough pressure over the surface of the balloon in order to counteract the gas on the inside of the balloon from expanding.
How much work does a student (m = 60 kg) do when he Climb a tower 80 m high?
Answer:
W = 47040 J
Explanation:
Given that,
The mass of a student, m = 60 kg
Height of the tower, h = 80 m
We need to find the work done in climbing the tower. The work done is given by :
W = mgh
So,
W = 60 × 9.8 × 80
W = 47040 J
So, the required work done is 47040 J.

During spring semester at MIT, residents of the parallel buildings of the East Campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. A balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. Assume that the stretching of the hose obeys Hooke's law with a spring constant of 88.0 N/m. If the hose is stretched by 4.20 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length
Answer:
The work done on the hose by the time the hose reaches its relaxed length is 776.16 Joules
Explanation:
The given spring constant of the of the spring, k = 88.0 N/m
The length by which the hose is stretched, x = 4.20 m
For the hose that obeys Hooke's law, and the principle of conservation of energy, the work done by the force from the hose is equal to the potential energy given to the hose
The elastic potential energy, P.E., of a compressed spring is given as follows;
P.E. = 1/2·k·x²
∴ The potential energy given to hose, P.E. = 1/2 × 88.0 N/m × (4.20 m)²
1/2 × 88.0 N/m × (4.20 m)² = 776.16 J
The work done on the hose = The potential energy given to hose, P.E. = 776.16 J
