Answers
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.

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
Answers
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
Answers
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.
