A solution contains 25.0 g of nano3 per 110.0 g of solution, then the concentration in ppm is 0.5 ppm.
Concentration in parts per million (ppm) indicates how many parts of solute are in 1,000,000 parts of solution. For example, saline is a dilute aqueous solution of sodium chloride NaCl(aq) with a concentration of 9,000 ppm.
The key point of PPM is to indicate how many "units" of substance A are for every million total units of solution or mixture. Percentages, in contrast, are very similar measures to PPMs, as they tell you how much there is "out of 100". Just like we can say we have a 7% solution, we can say we have a 36 PPM solution.
The most important thing to remember when performing PPM calculations is that the units you choose for the solution and the units of the substance of interest must be the same. For example, you cannot use solute mass and total solution volume. To get reasonable results, you should use mass and mass or volume.
It is the ratio of the number of grams of solute for every one million grams of solution
Therefore,
ppm = gram of solution/ grams of solute ×10⁶
= 5.0×10⁻⁵/100 ×10⁶
=0.5 ppm

What is specific heat capacity ?Specific heat capacity is the amount of thermal energy required to raise the temperature of a unit mass of a substance by one degree. It is typically measured in joules per kilogram-Kelvin (J/kg-K). Specific heat capacity is an important thermodynamic property since it is related to the amount of energy needed to increase the temperature of a material. It is also related to the amount of heat released or absorbed when a material undergoes a change of temperature. In general, materials with higher specific heat capacity require more energy to increase their temperature, and materials with lower specific heat capacity require less energy.

is there any way to pull on your partner’s force sensor without your partner’s force sensor pulling back? Try it
A force sensor is a device used to measure force or weight. Force sensors are commonly used in a wide range of applications, including scientific experiments, industrial processes, and athletic training.
It is not possible to pull on a partner's force sensor without the force sensor pulling back. This is because of the basic principles of physics, specifically Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In other words, when a force is applied to an object, the object will respond with an equal and opposite force.
In the case of a force sensor, if you try to pull on the sensor, the sensor will respond by applying an equal and opposite force back to you. This is what makes the force sensor work; it measures the force applied to it and then provides a measurement of that force in response.
In conclusion, it is not possible to pull on a partner's force sensor without the force sensor pulling back. This is due to the basic principles of physics and the fact that a force sensor measures force by responding with an equal and opposite force to the one being applied to it.

B) circular epicycle whose center, in turn, moves around the Earth.
The Ptolemaic model of the Solar System has each planet moving along a circular epicycle whose center, in turn, moves around the Earth.
Option B is correct.
The Ptolemaic model of the Solar System was an ancient model that was developed by the Greek astronomer Ptolemy in the 2nd century AD.
In this model, each planet was believed to move along a circular path known as an epicycle.
The center of each epicycle was in turn believed to move around the Earth in a circular path, with the Earth being at the center of the Solar System.
This model was widely accepted for over a thousand years and was considered to be a complete and accurate representation of the Solar System.
However, it was later discovered to be incorrect and was eventually replaced by the heliocentric model of Copernicus and later the laws of motion and gravitation developed by Isaac Newton.
Despite its errors, the Ptolemaic model remains an important milestone in the history of astronomy and science.

a. absorption c. refraction b. reflection d. transmission
"Refraction" happens when light energy bends as it passes from one type of substance to another type. Therefore, option c is the correct answer.
What is Refraction?Refraction is the bending of a light wave as it passes from one type of substance to another type. Refraction occurs as a result of changes in density and speed. For instance, light slows down as it enters water from air. When light travels through a fast medium and into a slow medium, the light beam is refracted, which causes it to bend in the direction of the boundary between the two media.

When a bicycle is at point A and travelling at a speed of 9 m/s, its magnitude increases at a rate of v' = 0.2 m/s2, or by 0.2 m/s2.
The rate at which velocity changes in relation to time is known as acceleration, and it is a vector quantity that has both magnitude and direction. The bicycle's acceleration at point A in this scenario is equal to 0.2m/s2, as the bicycle's velocity is rising at a constant rate of 0.2m/s2. Accordingly, the bicycle's speed is growing by 0.2 m/s every second and will keep doing so until a net force intervene to slow it down or stop it.This data gives a snapshot of the bicycle's motion at a particular moment in time (when it passes point A).

The mass of 10 trillion silver atoms is approximately 6.6 x 10^-7 grams.
To determine the mass of 10 trillion silver atoms, we need to know the atomic mass of silver. Silver is a chemical element with the atomic number 47 and its atomic mass is 107.87 amu (atomic mass units). One amu is equivalent to 1.66 x 10^-24 grams.
So, to find the mass of 10 trillion silver atoms, we need to multiply the atomic mass of one silver atom by the number of atoms:
mass = atomic mass * number of atoms
mass = 107.87 amu * 10^13 atoms
mass = 1.0787 x 10^-22 grams * 10^13 atoms
mass = 1.0787 x 10^-9 grams * 10^13 atoms

in the Holocene era lived Homo sapiens or intelligent humans. Therefore, culture as a human creation experiences extraordinary development and progress.
About anthropoceneEtymologically, the word Anthropocene comes from the Greek word "anthropos" which means human. Human activities have become numerous and very intensive to the point of rivaling the great power of nature, which means that now humans have changed the order of the earth so that they become the main determining factor for natural motion,
Today, humanity has equaled or surpassed some of nature's great forces in changing the biosphere and many parts of the earth's system of functioning.

what is the color of lava when it is at its hottest?
a. Crimson
b. Orange
c. Yellow
d. red
The color of the lava when it is in its hottest state will be b) orange color.
The color of lava depends on temperature. Starts bright orange (1000-1150 C). On cooling, the color changes from bright red (800-1000 °C), then dark red (650-800 °C), to brownish red (500-650 °C). Solid lava will be black (but can still be very hot). The hottest lava that exists today is called "mafic" and is the type that contains mineral compounds that melt at the highest temperatures. An electric blue flame that looks like lava. Despite the name, this phenomenon is actually a sulfur fire that resembles the appearance of lava rather than actual lava from a volcanic eruption.

Two masses m and 2m approach each other along a path right angle to each other. After collision they stick together and move off at 2m/s at angle 37° to the original direction of the mass m what where the initial speed of the two particles?
The initial speed of the mass "m" object is 4.79 m/s, while the initial speed of the mass "2m" object is 1.81 m/s.
the two masses' initial motional speed
Applying the law of conservation of linear momentum, the two masses' initial speed is determined as follows: m1u1 + m2u2 = v(m1 + m2).
Angle between the two masses is equal to 90 degrees if m is in the horizontal direction and 2m is in the vertical direction.
What do starting and final speeds mean?When gravity first exerts force on an object, its initial velocity defines how quickly the object moves. The final velocity, on the other hand, is a vector number that gauges a moving body's speed and direction after it has reached its maximum acceleration.
