Answer: density, Omass, radiation, pressure because Radiation pressure is the mechanical pressure exerted upon any surface . Small bodies are more affected than large ones because of their lower mass relative to their surface area formed by the radiation pressure of the young stars reduces the cluster mass enough to allow rapid dispersal.
Explanation: I Hope that helped!!!
mass, pressure, density
two students are working together to build a birdhouse. Student 1 applies a force of 10 N to a wooden board in order to slide it across the table to student 2. If the force of fraction resisting the student ´s push is 4 N, what is the net force acting on the board?
Answer:
6
Explanation:
if there is 10n and the friction is 4n on the table then it is 6n.

What is the equal and opposite force for the Earth's force of gravity pulling down on the person as
described by Newton's third law?
Answer:
Normal force
Explanation:
normal force always perpendicularly points away from a surface
Normal force is the equal and opposite force for the Earth's force of gravity pulling down on the person as described by Newton's third law.
What is force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

Why is gunshot residue important for a forensic scientist? What are the potential complications with this type of evidence?
FORENSICS
Answer:
Gunshot residue is important to forensic scientists because it can help measure the firing distance of a weapon, or if someone has fired a weapon lately based on what's on their hands. The potential complications of this evidence include it being uncertain if the residue is from another firing. This type of evidence can also be uncertain in a courtroom when firing distance is drawn into question.

Which of the elements below has the largest electronegativity? Na, Mg, S, P?
HURRY!!!
Answer:
Electronegativities generally decrease from top to bottom within a group due to the larger atomic size.
Of the main group elements, fluorine has the highest electronegativity (EN= 4.0) and cesium the lowest (EN=0.79).
Explanation:
Sulfur has the largest electronegative element. Therefore, option C is correct.
What is electronegativity?Electronegativity is a measure of an atom's ability to attract electrons toward itself in a covalent bond, and it generally increases as you move across a period from left to right in the periodic table.
The type of bond that exists between atoms will depend on the electronegativity of the system.
Out of the given elements, S (sulfur) has the largest electronegativity. Sulfur has an electronegativity value of 2.58 on the Pauling scale, while Na (sodium) has an electronegativity value of 0.93, Mg (magnesium) has an electronegativity value of 1.31, and P (phosphorus) has an electronegativity value of 2.19. Therefore, option C is correct.

Answer:
Matter has mass and takes up space.
Explanation:
Matter is everything around you. Atoms and compounds are all made of very small parts of matter.
Mass is a measure of the amount of matter in an object.
Please help me vote you brainiest
Answer:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces. This always results in a stronger force than either of the individual forces alone
A popular radio station broadcasts with a frequency of 94.7 MHz. What is the
wavelength of the broadcast? (1 MHz = 1x106 Hz).
Answer:
λ = 0.032×10² m
Explanation:
Given data:
Frequency of broadcasts = 94.7 MHz
Wavelength of broadcasts = ?
Solution:
Frequency of broadcasts = 94.7× 10⁶ Hz
Formula:
Speed of wave = frequency × wavelength
3×10⁸ m/s = 94.7× 10⁶ Hz × λ
λ = 3×10⁸ m/s /94.7× 10⁶ Hz
Hz = 1/s
λ = 0.032×10² m

O D. CHCI
SUBMIT
Answer:
Empirical formula is CH₃Cl.
Explanation:
Given data:
Percentage of hydrogen = 6%
Percentage of carbon = 24%
Percentage of chlorine= 70%
Empirical formula = ?
Solution:
Number of gram atoms of H = 6/ 1 = 6
Number of gram atoms of C = 24 /12= 2
Number of gram atoms of Cl = 70/ 35.45 = 2
Atomic ratio:
C : H : Cl
2/2 : 6/2 : 2/2
1 : 3 : 1
C : H : Cl = 1 : 3 : 1

The piece of metal is magnetic
Answer:
Explanation:
Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.

What evidence do you need to determine that two rocks have some similar minerals because the minerals from the original rock was eroded then it was later compressed with other minerals to form a different rock.
Answer:
It comes from same parent material.
Explanation:
The two rocks have some similar minerals which indicates that they are comes from the same parent material but with the passage of time it is mixed with other minerals due to which they are some different in composition from one another so we can conclude that they comes from the same parent material due to the presence of some similar minerals.
