Identify the phase and division I or II for the following:
Metaphase II
Metaphase I
Telophase II
Cytokinesis
Answer:
Metaphase II
Explanation:
Metaphase II is the division of two daughter cells and is when sister chromatids line up in the middle of the cell. This is what appears to be happening in the image. Additionally, you can see that the chromosomes have already crossed over.
Metaphase I only involves 1 cell, not 2 daughter cells.
Telophase II and Cytokinesis are when the cell splits. Also, Telophase II would result in 4 daughter cells, not just 2.

Ocean waves are hitting a beach with a frequency of 0.100 Hz. Their average wavelength is 15.0 m. What is their average speed?
What is the frequency of a pendulum that is moving at 30 m/s with a wavelength of 0.32 m?
Answer:
Average speed=1.5 m/s
Frequency of pendulum=93.75Hz
Explanation:
We are given
Frequency, [tex]f=0.100Hz[/tex]
Average wavelength =[tex]\lambda=15m[/tex]
Speed of pendulum, [tex]v=30m/s[/tex]
Wavelength, [tex]\lambda'=0.32m[/tex]
We have to find the average speed and frequency of pendulum.
We know that
Speed,[tex]v=\lambda f[/tex]
Using the formula
Average speed,[tex]v=15\times 0.1=1.5m/s[/tex]
Hence, the average speed =1.5m/s
Frequency, [tex]f=\frac{v}{\lambda'}[/tex]
Using the formula
[tex]f=\frac{30}{0.32}[/tex]
[tex]f=93.75Hz[/tex]
Hence, the frequency of a pendulum=93.75Hz

There is a scale with a basket on it. A brick, brick #1 is placed on the scale. The brick has a mass of 10 kg. If the brick is not moving on the scale, are the forces balanced or unbalanced?
Answer:
The forces are balanced
Explanation:
Since the brick is not moving on the scale, it means that the forces are balanced. An unbalanced force would only be present if there is motion of the brick. So, since the brick does not move, the net force on it is zero. Thus, the forces on it are balanced.

Coulomb's Law says that the forces between any two charges depends ___________.
Question 7 options:
A. Directly on the size of the charges
B. Inversely on the square of the distance between the charges
C. Directly on the square of the distance between the charges
D. A&B
E. A/C
Coulomb's Law says that the forces between any two charges depends directly on the size of the charges and inversely on the square of the distance between the charges. The correct option is D. A & B
Coulomb's lawFrom the question, we are to determine the correct option.
First, we will state Coulomb's law.
Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects
That is,
[tex]F \propto \frac{Q_{1} Q_{2} }{r^{2} } [/tex]
Where F is the electrical force
[tex]Q_{1} \ and \ Q_{2}[/tex] are the charges
r is the distance between the objects
From the law, we can observe that the forces depends directly on the size of the charges - Option A
and the forces also depends inversely on the square of the distance between the charges - Option B
Hence, the correct option is D. A & B

pls mark me brainliest
The net force acting on the airplane if, An airplane is flying at 80 kilometers per hour when a strong tailwind, traveling in the same direction at 5 kilometers per hour is 85 km/hr so, option A is correct.
What is force?Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces.
For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.
Given:
An airplane is flying at 80 kilometers per hour when a strong tailwind, traveling in the same direction at 5 kilometers per hour,
Calculate the net force acting on the airplane as shown below,
The net force acting on the airplane = The velocity of the airplane + velocity of the wind (As they both are in the same direction)
The net force acting on the airplane = 80 km / hr + 5 km / hr
The net force acting on the airplane = 85 km / hr
Thus, the net force acting on the airplane is added.

A. A baseball thrown by a player.
B. A pebble falling to the ground
C. Fish swimming in the water
D. A sailboat sailing on a lake
An action which is an example of a force which operates at a distance is a pebble falling to the ground. Thus, the correct option is B.
What is force?A force is an influence which can be changed upon with the motion of an object. A force can cause an object with some amount of mass to change the velocity of the object, i.e., to accelerate the object. Force can also be described as a push or a pull of the object. A force is a vector quantity because it has both the magnitude and direction.
A pebble falling to the ground level is an example of the force which operates at a specific distance. A force applied on the pebble covers some distance.
Therefore, the correct option is B.

What is the only part in our body we do not stretch?
Answer:
The quadriceps consists of four muscles: the skinny rectus femoris and the three huge “vasti” — vastus lateralis/intermedius/medialis. The vasti are only elongated by knee flexion, which is limited to about 120˚ when the calf hits the hamstrings. The vasti cannot be stretched strongly.
Answer:Masseter and temporalis
Why it’s unstretchable: The jaw can only open so far.
Why it’s a dang shame: Jaw tension is epidemic, and trigger points in these muscles cause a wide array of strange face and head pains, including toothaches, headaches, and earaches.
Which of the scientist responsible for cell theory would be the most likely to write a book titled Cells Come from Cells
Answer:
Rudolf Virchow
Explanation:
popularized the cell theory in an 1855 essay entitled “Cellular Pathology.” (b) The idea that all cells originate from other cells was first published in 1852 by his contemporary and former colleague Robert Remak (1815–1865).
Explanation:
Rudolf Virchow
-Rudolf Virchow would be the most likely to write a book titled 'Cells Come From Cells' because in cell theory he added a point that 'All cells arises from pre-existing cells. ' which means that all cells come from another cells which is as similar as the title of the book
According to Newton's second law equation, what is the relationship between net force applied and the acceleration of the object
Acceleration is inversely proportional to the net force
if acceleration goes up forces goes down
if acceleration goes down mass goes down
Acceleration is directly proportional to the net force
Answer:
Acceleration is directly proportional to the net force
Explanation:
The net force acting on an object is given by :
F = ma
Where
m is mass
and
a is acceleration
It can be seen that the relation between the net force and the acceleration is direct i.e. as the acceleration increases, the net force will increase. Hence, the correct option is (d).

What is longitudinal wave?
A sound wave is called a longitudinal wave because compressions and rarefactions in the air produce it.
The air particles vibrate parallel to the direction of propagation.
A longitudinal wave consists of a repeating pattern of compressions and rarefactions.
Thus, the wavelength is commonly measured as the distance from one compression to the next adjacent compression or the distance from one rarefaction to the next adjacent rarefaction.
Longitudinal waves move through a medium from the point of the disturbance in the form of compressions (where particles of the medium are bunched together) followed by rarefactions (where particles of the medium are farther apart).
In longitudinal waves, the distance from one compression to the next is the wavelength.
Therefore,
In longitudinal wave the wavelength is longer.

An experiment is designed to test what color of light will activate a photoelectric cell the best. The photocell is set in a circuit that "clicks" in response to current. The faster the current, the more clicks per minute. In this experiment, the number of clicks in one minute is recorded for each color of light shining on the photocell. To change the color of light, a different color of cellophane is placed over the same flashlight and the flashlight is then located a specific distance from the photocell.
Which of the following was not kept constant?
the color of the light after it has passed through the cellophane
the source of the original light
the distance of the light from the photocell
the test for photocell activation
Answer:
the color of the light after it has passed through the cellophane
Explanation:
Since in the given experiment, there is an impact of various colors of light on the cell i.e. photoelectric that should be measured. The photocell should be placed in a circuit when the current would passed. For every color that falls on the photocell, the value of the current that passed via the cell represent an idea.
In the given situation the color of light shows an independent variable and the dependent variable is clicks per minute or the current that passed through the cell
