Answer:
Explanation:
Cart A is moving to the right with constant speed i.e. net acceleration is zero
because acceleration is change in velocity in given time
Cart B is moving towards right with gradually speed up so there is net acceleration which helps to increase the velocity s
This indicates the net force acting on the cart towards right
For cart C there is gradual slow down of cart which indicates cart is decelerating and a net force is acting towards which opposes its motion.

Explanation:
The three major difference between Pluto and the other Terrestrial planets are
1. Pluto's orbit is far from being circular. Its orbit has highest eccentricity,meaning that its distance from sun varies more than any other planet of the solar system.
2. The ratio of the size of the planet to size of moon is highest for the for Pluto. its moon Cheron is quite large which is surprising as Pluto gravitational force is not much.
3.Pluto's orbit is the most tilted orbit of the solar system.
Answer: 1.11 x 10⁸ Pa
Explanation:
At any deep, the absolute pressure is the same for all points located at the same level, and can be expressed as follows:
p = p₀ + δ. g . h, where p₀ = atmospheric pressure = 101, 325 Pa
Replacing by the values, we get:
p= 101,325 Pa + 1025 Kg/m³ . 9.8 m/s². 11,033 m = 1.11 x 10⁸ Pa.
The theories change over time because new information and technology may be developed that influence the theory. Therefore, option B is correct.
As new information and perspectives become available, established theories may be changed or refuted. If a new or modified theory explains all the old theory did and then some, scientists are likely to accept it.
When fresh data emerges that refutes an existing theory, scientific theories can be revised or replaced. All scientific theories are founded on observable, testable data, and they can be changed when new information is found that contradicts the present idea.
When certain features of a hypothesis are refuted by fresh experimental data, a theory might be altered in science.
Thus, option B is correct.

Theories change over time due to new information, technology, and the perspectives of new generations of scientists.
Theories change over time for several reasons. First, new information and technology may be developed that influence the theory. For example, advancements in experimental methods can provide new information and lead to the refinement or modification of theories. Additionally, theories may change with each new generation of scientists as they bring new perspectives and ideas. It is important to note that theories may or may not be supported by new information, and scientists do not change the definition of theory to have their ideas accepted.

KNO3 of 10g will undergo crystallization at 0 °
Because the heavier the KNO3 mass will require a higher temperature in the dissolution process.
Potassium nitrate is a nitrate salt compound from potassium with the molecular formula KNO3. Potassium nitrate salt can be made by reacting potassium chloride with sodium nitrate. If the saturated solution each of the solution is mixed with each other, then it will form sodium chloride salt because NaCl in water is small, the salt will settle. By cooling the filtered filtrate KNO3 will undergo crystallization
This compound decomposes with oxygen evolution at 500 ° C according to the reaction equation:
2 NaNO3 (s) -> 2NaNO 2 (s) + O2 (g)
Crystallization is separation by forming crystals so that the mixture can be separated. A gaseous or liquid substance can cool or condense and form crystals because it undergoes a crystallization process. Crystals will also form from a solution that will be saturated with a certain solvent. The more the number of crystals, the better, because the less likely to be polluted by dirt.
Potassium Nitrate has a physical white powder that is easily soluble in water and odorless. Meanwhile, to analyze the structure and characteristics of Potassium Nitrate MM2 data processing is used in the Chemoffice 15.0 application. This data processing is used to determine the shape of compounds, types of bonds in molecular movement compounds and other parts that can not be observed directly by the eye without the aid of tools. And for the form of compounds in 2 dimensions and 3 dimensions used Chemdraw 15.0 and Chem3D 15.0 applications
