Answer:
According to Newton's second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.

Which of the following is accurate
regarding intrusive igneous rock?
A. It forms on the earth's surface.
B. It forms inside the earth.
C. It is made from sediments.
D. It has a fine-grained texture.
Answer:
B
Explanation:
I believe because intrusive stays within the earth
The accurate statement regarding the intrusive igneous rock is that It forms inside the earth.Hence, Option (B) is correct.
What are Intrusive igneous rock ?Intrusive, or plutonic, igneous rock forms when magma remains inside the Earth's crust where it cools and solidifies in chambers within pre-existing rock.
The magma cools very slowly over many thousands or millions of years until is solidifies.
Therefore, The accurate statement regarding the intrusive igneous rock is that It forms inside the earth.Hence, Option (B) is correct.

SITUATION # 2: Every morning we drink milk to strengthen our bones. You
prepare a 100ml with a 5% powdered milk mix solution for your mother.
She asks you how many grams of milk you used for her drinks. What
would be your response to her question?
The amount of milk present on 5 % of 100 ml milk powder solution is 95 grams.
The solution was prepared by dissolving 5% milk powder in 100 ml of the solution.
The amount of milk powder will be = [tex]\rm 100\;\times\;\frac{5}{100}[/tex] ml
The amount of milk powder = 5 ml.
The amount of milk = Total - amount of milk powder
The amount of milk = 100 - 5
The amount of milk = 95 ml.
Since the density of milk = 1 gm/ml
The amount of milk in 95 ml of solution = 95 grams.
In the solution of 5 % milk powder in 100 ml milk, there would be 95 grams of milk.

How are protons and neutrons the same and how are they different?
Explanation:
Protons, Neutrons and Electrons are the three primary subatomic particles that form an atom.
Protons and Neutrons are large particles and are densely compacted into the nucleus of the atom. Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge.
Together the protons and Neutrons make up the mass of the atom.
Electrons are electrochemically negatively charged particles that move random around the nucleus. They have a relatively small mass compared to Protons and Neutrons. They are found in electron clouds that surround the nucleus and their movement and properties provide for the bonding characteristics of each atom.

what did rutherford's gold foil experiment tell about the atom
Answer:
The alpha particles that were fired at the gold foil were positively charged. ... These experiments led Rutherford to describe the atom as containing mostly empty space, with a very small, dense, positively charged nucleus at the center, which contained most of the mass of the atom, with the electrons orbiting the nucleus.
A sample of helium gas at a pressure of 0.538 atm and a temperature of 256 °C, occupies a volume of 437 mL. If the gas is cooled at constant pressure until its volume is 316 mL, the temperature of the gas sample will be
Answer:
110 °C
Explanation:
The following data were obtained from the question:
Initial pressure (P1) = 0.538 atm
Initial temperature (T1) = 256 °C
Initial volume (V1) = 437 mL.
Final pressure (P2) = constant = 0.538 atm
Final volume (V2) = 316 mL
Final temperature (T2) =?
Next we shall convert 256 °C to Kelvin temperature. This Can be obtained as follow:
T(K) = T(°C) + 273
Initial temperature (T1) = 256 °C
Initial temperature (T1) = 256 °C + 273 = 529 K
Next, we shall determine the new temperature of the gas as illustrated below:
Pressure = constant
Initial temperature (T1) = 529 K
Initial volume (V1) = 437 mL.
Final volume (V2) = 316 mL
Final temperature (T2) =?
Applying the Charles' law equation, we have:
V1 /T1 = V2 /T2
437/529 = 316/T2
Cross multiply
437 × T2 = 529 × 316
437 × T2 = 167164
Divide both side by 437
T2 = 167164 / 437
T2 = 382.5 ≈ 383 K
Finally, we shall convert 383 K to celsius temperature. This can be obtained as follow:
T(°C) = T(K) – 273
T(K) = 383 K
T(°C) = 383 – 273
T(°C) = 110 °C
Therefore, the new temperature of the gas is 110 °C
Which statement best describes why radioactive atoms can be used to date materials?
A.
Nonradioactive atoms in rocks eventually turn into radioactive atoms.
B.
The Sun interacting with atoms in a rock causes new atoms to form over time.
C.
The ratio of radioactive atoms to other kinds of atoms changes over time.
D.
The number of radioactive atoms in a substance increases over many years.
The ratio of radioactive atoms to other kinds of atoms changes over time. Hence, option C is correct.
What is radioactive decay?In the process of radioactive decay the unstable atom nuclei of the parent nucleus break down and split so as to release the daughter atoms or nuclei along with the release of energy in the form of heat. Thus as the decay process proceeds the concentration of the parent atom decreases but the concentration of the daughter atom increases.
Radioactive atoms can be used to date materials because the radioactive decay occurs at a known rate, and the density of fission tracks for the amount of uranium within a mineral grain can be used to determine its age.
Hence, option C is correct.
