How did anders celsius devise the temperature scale?
Anders celsius devise the temperature scale using a mercury thermometer.
The Celsius temperature scale, which measures heat or cold, from 0° for frozen water, to 100° for boiling water, was invented by Anders Celsius, a Swedish astronomer, in 1742. He named the scale the centigrade scale, and people may occasionally still see temperatures listed with this term. In 1954, however, scientists officially named the temperature scale after the astronomer to honor his work.The original scale differs from the modern use of Celsius. The creator set 0 as the boiling point of water and 100 as its freezing point. This was reversed shortly after his death to the more modern usage.One of the advantages of the modern scale is that the calculations from 0 to 100 are far easier than Fahrenheit calculations.In modern times, most countries use Celsius measurements, not simply for the weather, but for temperature measurements in baking and other applications. Scientists throughout the world use a combination of this scale and Kelvin measurements. The Kelvin scale is based on the fixed points of absolute zero, where nothing could be colder, and all matter solidifies, and the triple point of water, where gas, liquid and solid water are equally used. This scale is particularly useful for discussing extreme temperatures.To know more about temperature visit:

The volume of the sphere is 41.89 centimeters cubed.
What is sphere?A sphere is a three-dimensional shape that is made up of all points that are the same distance from the center. It is a perfectly round, symmetrical object that looks the same from any angle. A sphere is one of the most basic shapes in geometry and is found in many everyday objects. A soccer ball, basketball, and even a globe are all examples of spheres. The surface of a sphere is called a spherical surface and has no edges or vertices.
The volume of a sphere is calculated using the formula V = 4/3 * π * r^3, where r is the radius of the sphere. In this case, the radius of the sphere is 12 centimeters, so the volume would be 4/3 * π * 12^3 = 4,188.8 cubic centimeters, which is equivalent to 41.89 cubic centimeters. Therefore, the answer is 41.89 centimeters cubed.

How many aneuploid gametes are produced from a nondisjunction event in meiosis II?.
Two gametes will be produced by meiosis II, which will have unequal number of chromosomes.
A nondisjunction event during meiosis II results in the production of two aneuploid gametes. Nondisjunction is a type of error that occurs during meiosis, the process by which cells divide to produce sperm and egg cells. During meiosis, chromosomes first replicate and then line up in pairs along the center of the cell. Then, the pairs of chromosomes are pulled apart, one to each of the two new cells, ensuring that each cell gets one copy of each chromosome. Nondisjunction occurs when chromosomes fail to separate properly, resulting in one daughter cell receiving an extra copy of a chromosome, while the other daughter cell is missing a copy. In the case of meiosis II, this means that the two gametes produced will have an unequal number of chromosomes. One gamete will have an extra copy of a particular chromosome, while the other gamete will be missing a copy of that chromosome. These gametes are called aneuploid because they have an abnormal number of chromosomes.
Aneuploidy can have serious consequences, as the extra or missing chromosomes can disrupt the normal genetic makeup of the organism. Aneuploidy in sperm or egg cells can lead to the formation of genetically unbalanced zygotes when fertilization occurs, which can result in various genetic disorders and developmental abnormalities. For example, Down syndrome, a common chromosomal disorder, is caused by an extra copy of chromosome 21. Similarly, Turner syndrome is caused by the absence of one X chromosome in females, resulting in a total of 45 chromosomes.
In summary, a nondisjunction event in meiosis II results in the production of two aneuploid gametes, each with an abnormal number of chromosomes, which can lead to various genetic disorders and developmental abnormalities.

Is momentum infinite in space?.
As a result, there is almost no friction in space to slow moving objects. A ship in space, unlike a ship on the water, does not require constant thrust to keep moving forward. After the engines are turned off, the momentum of a space ship will continue to propel it forward indefinitely at a constant speed.
What is momentum?Momentum is defined as a body's amount of motion. It is measured by "mass velocity," since velocity and the direction of the body's motion impact momentum. Momentum is a vector quantity since velocity is a vector and mass is a scalar variable. Momentum is defined as the product of mass and velocity. Momentum is a body's "power" while it moves, indicating how much force it can exert on another. A bowling ball (large mass) traveling slowly (low velocity), for example, can have the same momentum as a baseball (small mass) thrown quickly (high velocity).

How many chromosomes are present in each cell after the completion of meiosis nondisjunction?.
After the completion of meiosis nondisjunction, 2 of the four daughter cells will have a normal complement of 23 chromosomes and the other two daughter cells will be aneuploid, one with n+1 and other with n-1 chromosomes.
The cell cycle has two main parts which is-
The Interphase and mitosis/meiosis. Interphase is further subdivided into three other phases.
Nondisjunction can occur during either mitosis or meiosis, but the effects of meiosis are more widely studied because they have a direct impact on the offspring. Meiosis, also known as reductional division, is the process by which chromosome numbers are reduced and haploid gametes are produced. Gametes are sex cells that merge during sexual reproduction to produce new, unique offspring — eggs in females and sperm in males. Nondisjunction creates gametes with abnormal chromosome numbers, which result in offspring with ploidy numbers after fertilization.

a lever with an effort arm of 10 meters and a load arm of 2 meters is used to lift an object weighing 220 newtons to a height of 4 meters. if 400joules of work is done, how much force must have been applied?
The force applied must have been 1100 Newtons.
To calculate the force applied, we can use the equation for work done by a lever:
Work done = effort force x effort arm x cos(theta)
where theta is the angle between the effort arm and the load arm. Since the angle is not given, we can assume it to be 90 degrees.
We know that the work done is 400 joules, the effort arm is 10 meters, and the load arm is 2 meters.
We can substitute these values into the equation:
400 = F_effort x 10 x cos(90)
The cosine of 90 is zero.
So
F_effort = 400/0 = undefined
To find the force applied, we can use the principle of the mechanical advantage of the lever.
MA = load arm/effort arm = 2/10 = 1/5
F_effort = F_load / MA = 220 N / (1/5) = 1100 N
So the force applied must have been 1100 Newtons.
