Boyle’s Law: When____ is held constant, the pressure and volume of a gas are___ proportional.
It didnt give me a word bank
No link answers please
Answer:
When temperature is held constant, the pressure and volume of a gas are not proportional.
Explanation:
That is Boyle's Law
Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.
What is meant by gas laws ?Gas laws are defined as the laws that govern the properties of gases by determining the relationships between the pressure, volume and temperature of the gases.
Here,
Boyle's law is the gas law that governs the relationship between the pressure and volume of gases.
Boyle's law states that, for an ideal gas at a unit mass, the pressure of the gas is inversely proportional to the volume of the gas, at constant temperature.
P [tex]\alpha[/tex] 1/V
PV = a constant
When the temperature of the gas is held constant.
Hence,
Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.

Answer:
What inferences can you make about the melting points of the different substances and the motion of their particles, based on the data? (ignore that needed it here so i could see it better.)
Explanation:
Butter has a lower melting point than the cheese and the wax. The motion of the cheese were a little separated while the butter articles have more space in between. The wax had the closest particles.
I dont know if that makes sense?

An archer shot a 0.07 kg arrow at a target. The arrow accelerated at 4,000 m/s2 to reach a speed of 50.0 m/s as it left the bow. During this acceleration, what was the net force on the arrow?
A) 280 N
B) .0000175 N
C) 57,142 N
D) 3.5 N
The net force which has to be applied on the arrow of 0.07kg to accelerate at the rate of 4000m/s² is 280N. Thus, the correct option is A.
What is Force?
A force is an influence which can be a push or a pull that can change the motion of an object. A force can cause an object with some mass to change the velocity, i.e., results into acceleration. A force is a vector quantity as it has both the magnitude and direction.
Force applied on an object can be calculated by the formula:
f = m × a
where, f = force applied,
m = mass of the object,
a = acceleration of the object
Therefore, the force applied on the arrow is:
f = m × a
m = 0.07kg
a = 4000m/s²
f = 0.07 × 4000
f = 280N
Therefore, the correct option is A.

Why does autumn start in different months of the year in North America and South America?
A) The earth is tilted on its axis creating different seasons in the North & Southern Hemispheres at different points in its revolution around the sun
B) The earth is at a different distance from the sun due to its revolution
C) The sun is stronger during autumn due to the earth's elliptical orbit.
D) The earth’s tilt causes the Northern Hemisphere to receive more sun year-round Eliminate
Answer:
D
Explanation:
Autumn start in different months of the year in North America and South America due to the tilt in earth's axis creating different distance from the sun for different regions.
What are seasons ?A season is a time of year that can be identified by unique climatic features. Spring, summer, fall, and winter all occur in regular succession. Each has distinctive seasonal variations in light, temperature, and weather.
Each seasons starts at different month in two hemispheres of earth. This s due to the fact that, earth's axis is not perfectly circular and it is slightly tilted towards sun.
When the Northern Hemisphere is tilted toward the sun in June, more of the day is spent being illuminated by the sun's rays than it is in winter. As a result, there are longer daylight hours.
There are fewer daylight hours in December because the Northern Hemisphere is tilted away from the sun. Similarly the autumn season also differ from that of the southern hemisphere.

The Humbolt squid can travel 410 meters in 60 seconds. The squids average speed is ____. (Round to the nearest tenth)
Answer:

Explanation:
A baseball is thrown at 90 mph from east to west over a distance of 60 ft. What is
true of the ball's motion?
Its speed is 90 mph to the west.
Its acceleration is 30 mph.
Its velocity is 90 mph to the west.
Its acceleration is 150 mph.
Answer:
Its acceleration is 30 mph.
Explanation:
The true of the ball's motion will be that the velocity is 90 mph to the west. Velocity is the vector quantity. Because it shows the direction.
What is acceleration?
Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec². It is a vector quantity. It requires both magnitudes and direction to define.
The given data in the problem is
The velocity of baseball is,V= 90 mph
The distance travelled in mile is; d=0.0113636 mile
The time period is obtained as;
[tex]\rm t = \frac{d}{v} \\\\ \rm t = \frac{0.0113636}{90} \\\\ t=1.2 \times 10^{-4} \ hr[/tex]
The acceleration is obtained is 0.00108 mile/hr².
Hence, the true of the ball's motion will be that the velocity is 90 mph to the west.

The particle model of matter is one of the most useful scientific models because it describes matter in all three states. Understanding how the particles of matter behave is vital if we hope to understand science!
The model also helps us to understand what happens to the particles when matter changes from one state to another.
The following diagram shows different changes of state, as well as which processes are the reverse of each other. Melting and freezing are the reverse processes of each other and so are evaporation (boiling) and condensation.
