I beleive its the middle/second option :)
Explanation:
Sorry if I'm wrong but Newton's third law is "for every action (force) in nature there is an equal and opposite reaction." meaning if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A so I beleive the moon would push up on the astronaut with a force of 300 N
I hope this helps, have a good day :)

Jamie rolls a 6-sided die 30 times and determines that the experimental probability of rolling a 2 is Start Fraction 1 over 15 End Fraction. The theoretical probability of rolling a 2 is Start Fraction 1 over 6 End Fraction. What could Jamie do to make his experimental results more closely match the theoretical probability?
Answers
Answer:
Conduct more trials
Explanation:
Theoretical Probability can be defined as what someone is expecting to happen
Experimental Probability on the other hand, is defined as what actually happens.
Probability is usually calculated in the same way for experimental probability and that of theoretical probability. You divide the total number of possible ways in which a particular outcome can happen, by the total number of outcomes itself.
In Experimental probability, the more times a probability is tried, it gets closer and even more closer to theoretical probability.
So, for the question, Jamie should improve the number of tries more, so as to get his experimental probability results to be closer to the theoretical probability result.
Answer:
A. He can increase the number of trials

Calculate the heat that must be supplied to
a 532 , stainless steel vessel containing 375 g
of water to raise its temperature from 35 C
to the boiling point of water 100°C. Cs. =0.51 J/g. degrees C
Answer in units of J.
Answers
Q must be supplied = 119523.3~J
Further explanationThe law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released
Q in = Q out
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
So from the question :
Q to the system(Q supplied) = Q water + Q steel vessel(Q gained)
[tex]\tt Q~supplied=m.c\Delta T(water)+m.c\Delta T(vessel)\\\\Q~supplied=375\times 4.18\times (100-35)+532\times 0.51(100-35)\\\\Q~supplied=101887.5+17635.8=119523.3~J[/tex]

NA
Explanation:
the other three options are alkali earth metals like magnesium (they are all in group 2). Sodium is the only one that is not an alkali earth metal.
The [tex]Na[/tex] element would be the least similar to magnesium ([tex]Mg[/tex] ).
Because all elements belongs to same group as magnesium except sodium.Why elements belong to same group are similar?The vertical row in the periodic table is called group.The elements in the same group shows similar properties because the number of valence electrons is same for elements in same group.What is valence electron?The electron/electrons present in valence shell is called valence electrons.

Calculate the density of helium if a balloon with a capacity of 5.00 L holds 0.890 g.
Answers
Answer:
Explanation:
Density is m/V. Also, 1 liter = 1000 [tex]cm^3[/tex]. So, we get 0.890/(5*1000) = [tex]1.78*10^{-4}[/tex] g/cm^3. You can convert this to kg/m^3 as well by multiplying it by 10. Depends which one you want.
The ratio of the mass in grams and volume in cubic meters gives the density. The density of 0.80 gm helium is 1.78 × 10 ⁻⁴ g/cm³.
What is density?Density is the amount or the number of entities that can be contained in an area. It is denoted by ρ and is calculated as,
Given,
Mass = 0.890 gm
Volume = 5000 cm³
ρ = Mass ÷ Volume
= 0.890 ÷ 5000
= 1.78 × 10 ⁻⁴ g/cm³
Therefore, 1.78 × 10 ⁻⁴ g/cm³ is the density of helium.

What factors are included on a phase diagram?
O A. Temperature and pressure
O B. Pressure and volume
O C. Mass and volume
O D. Heat and kinetic energy
Answers
Answer:
A. Temperature and pressure
Explanation:
The factors included in a phase diagram are the temperature and pressure conditions.
A phase diagram is a combined plot of three curves all in equilibrium;
Solid- liquid, liquid -gas, and solid -gas plots
On the vertical axis, we usually have the pressureOn the horizontal axis is where the temperature is represented. Most phase diagrams are used in chemistry and mineralogy to show areas in which different phases can exist at equilibrium.The factors included on a phase diagram are temperature and pressure and the correct option is option A.
A phase diagram is a graphical representation that shows the different phases of a substance (solid, liquid, and gas) as a function of temperature and pressure. It provides valuable information about the conditions at which different phases can exist and the boundaries between them.
The temperature is typically plotted on the horizontal axis, while the pressure is plotted on the vertical axis.
By examining a phase diagram, one can determine the melting point, boiling point, and critical point of a substance, as well as the regions of stability for each phase. Additionally, phase diagrams can reveal the existence of phase transitions such as melting, boiling, and sublimation.
Thus, the ideal selection is option A.

A.Diffusion
B.Exocytosis

Answers
Answer:
A. Diffusion
Explanation:
A.Diffusion - this is correct. Diffusion is the process where small molecules enter the cell by moving from a high concentration to a low concentration through a semi-permeable membrane.
B.Exocytosis - this is incorrect. Exocytosis is a cell transport mechanism where the cell uses a system of vesicles to transport cargo outside of the cell. The vesicles fuse to the cell membrane and deliver the cargo outside.
C.Osmosis - this is incorrect, osmosis is a type of diffusion specific to water molecules
D.Endocytosis - this is incorrect. Endoocytosis is a cell transport mechanism where the cell uses a system of vesicles to transport cargo into the cell. The cell membrane engulfs the molecules and brings them into the cell via the vesicle
