Calculate the change in the kinetic energy (KE) of the bottle when the mass is increased. Use the formula
KE = one half.mv2, where m is the mass and v is the speed (velocity). Assume that the speed of the soda bottle falling from a height of
0.8 m will be 4 m/s, and use this speed for each calculation.
Record your calculations in Table A of your Student Guide.
When the mass of the bottle is 0.125 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.250 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.375 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.500 kg, the KE is
kg m2/s2.
Answer:
The answers are the options 1, 2, 3, and 4
Explanation:
If you have any questions ask me please! :)
The kinetic Energy of the bottle falling from a height of 0.8m for different masses of (0.125,0.250,0.375,0.500)kg is (1,2,3,4) kgm*2/s*2 respectively.
Let's calculate the kinetic energy for different masses having a velocity of 4m/s in each case,
Using Formula:
K.E=\(1/2mv^{2}\)
When the mass of the bottle is 0.125 kg, the Kinetic Energy is
K.E=\(1/2(0.125)(4)^{2}\)
K.E=\(1/2(0.125)(16)\)
K.E=1/2(2)
K.E=1
When the mass of the bottle is 0.250 kg, the Kinetic Energy is
K.E=\(1/2(0.250)(4)^{2}\)
K.E=1/2(0.125)(16)
K.E=1/2(4)
K.E=2
When the mass of the bottle is 0.125 kg, the Kinetic Energy is
K.E=\(1/2(0.375)(4)^{2}\)
K.E=1/2(0.375)(16)
K.E=1/2(6)
K.E=3
When the mass of the bottle is 0.500 kg, the Kinetic Energy is
K.E=\(1/2(0.500)(4)^{2}\)
K.E=1/2(0.500)(16)
K.E=1/2(8)
K.E=4
Now we can calculate the change in kinetic energy (ΔKE):
ΔKE = KE(final) - KE(initial)
= 4 kg m*2/s*2 - 1 kg m*2/s*2
= 3 kg m*2/s*2

Place the parts of the human circulatory system in order from highest to lowest degree of internal organization.
→ → →
Answer: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows: Heart, Blood Vessels, Arteries, Veins, and Capillaries.
Explanation: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows:
Heart: The heart is a vital organ responsible for pumping oxygenated blood to the body and deoxygenated blood to the lungs. It consists of chambers (atria and ventricles) and valves that regulate blood flow.
Blood Vessels: Blood vessels form a network of tubes that transport blood throughout the body. They can be classified into three types: arteries, veins, and capillaries.
Arteries: Arteries are thick-walled blood vessels that carry oxygenated blood away from the heart to various parts of the body.
Veins: Veins are blood vessels that transport deoxygenated blood from the body back to the heart. They have thinner walls compared to arteries and contain valves to prevent backflow.
Capillaries: Capillaries are tiny, thin-walled blood vessels that connect arteries and veins. They facilitate the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
Please note that this arrangement is based on the internal organization of the circulatory system, with consideration given to the hierarchical structure and function of each component.

Why is it important to track our carbon and ecological footprint?
Answer: I got you Fam
Explanation:
it is one competing demand for biologically productive space
Answer:
The carbon footprint is a very important means to understand the impact of a person's behavior on global warming. This is why someone who effectively wants to contribute to stopping global warming, at least on an individual scale, needs to measure and keep track of their personal carbon footprint.
Why is it important to track your ecological footprint?
The Ecological Footprint is a simple metric. It is also uniquely comprehensive. Not only does it measure humanity's demand on our planet's ecosystems, but it is also key to understanding the inter-related pressures of climate change on the natural ecosystems on which humanity depends.
Why is knowing your carbon ecological footprint important?
Knowing your personal or organisational carbon footprint is useful for the following reasons: it enables you to identify and reduce GG emissions, it allows corporations to publish their environmental performance statistics, it can be used as information to raise awareness of environmental costs.

Weather is caused by the rising and falling of warm and cool air called ( ). These currents affect the different air pressures in the atmosphere( ) . Response area occurs when the air cools and begins to sink, while ( ) occurs when the air warms and begins to rise. The differences between these pressures are what causes
( ). Convection can also create ( ) in a small local area.
Answer:Movement of air caused by temperature or pressure differences is wind. Where there are differences of pressure between two places, a pressure gradient exists, across which air moves: from the high pressure region to the low pressure region. This movement of air, however, does not follow the quickest straight line path. In fact, the air moving from high to low pressure follows a spiralling route, outwards from high pressure and inwards towards low pressure. This is due to the rotation of the Earth beneath the moving air, which causes an apparent deflection of the wind to the right in the northern hemisphere, and left in the southern hemisphere. Consequently, air blows anticlockwise around a low pressure centre (depression) and clockwise around a high pressure centre (anticyclone) in the northern hemisphere (see Figure 3.1). This situation is reversed in the southern hemisphere.
