Answer:
Galileo threw two balls from a tower's summit. They were both the same size and shape, yet one weighed 50 grams and the other weighed 500 grams. As a result, the two balls collided at precisely the same time. This finding backs up Newton's law of gravitation, which states that things with more mass will be subjected to a larger gravitational force. Because the 500-g ball has higher inertia, it takes more force to accelerate it. That force is provided by the stronger gravitational pull, and the two balls descend at the same rate.
Explanation:
One of the famous experiments often associated with Galileo Galilei is the experiment involving objects of different masses dropped from the Leaning Tower of Pisa. While there is some debate regarding whether Galileo actually conducted this specific experiment, it is often attributed to him for its conceptual importance.
According to the account, Galileo dropped two objects of different masses, such as a heavy cannonball and a lighter musket ball, from the top of the Leaning Tower of Pisa. The experiment aimed to determine whether objects of different masses would fall at different rates, as was commonly believed at the time. The expected result, based on the Aristotelian view prevailing during Galileo's time, would have been that the heavier object (the cannonball) would have fallen faster than the lighter one (the musket ball).

What happened when there was not enough carbon dioxide in the atmosphere to trap the sun's heat about 600 mya?
Answer:
Decreased Temperatures
Explanation:
Because carbon dioxide traps heat in the atmosphere, a lessening of atmospheric carbon dioxide concentrations would mean that more heat could escape into space. This would result in a net decrease in the Earth's average temperature, assuming other factors remain the same.

Answer:
most potteries were Circular, Such as in Egypt they had slavery, but it wasn't like European slavery. They would grow their farms to provide for their families. one main way was to carry water back for their crops in circular plates and vases.
You could say Egyptian slavery wasn't slavery. it was mainly just everyone fending on their source of crops. And everyone could sell their crops for more produce.

What are the organs in the circulatory system
Answer:
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.A student experiments with two solutions containing the same solute concentrations
in a beaker that is divided by a semipermeable membrane, as shown.
In which direction will the water move so that the concentrations of the solutions
remain constant on both sides of the membrane?
A in both directions at different rates
B in both directions at the same rates
C toward the right side of the beaker
D toward the left side of the beaker
Answer:
B in both directions at the same rates
Explanation:
Solutions with the same amount of solute concentration is referred to as ISOTONIC. In an isotonic solution, there is NO net movement of water molecules because there is no osmotic gradient i.e. difference in solute concentrations.
In this case, a student experiments with two solutions containing the SAME SOLUTE CONCENTRATIONS in a beaker that is divided by a semipermeable membrane. Due to the equal amount of solute concentrations in both solutions, water moves into and out each membrane at an equal rate.
In order for the concentrations of the solutions to remain constant on both sides of the membrane, WATER MUST MOVE IN BOTH DIRECTIONS AT THE SAME RATE.

Answer:
X=16
Explanation:
We would need to convert the whole number (5) into a fractIon. By doing this, we multiply 5 by 3 to get 15. We also must add in the 1 form the 1/3 in the 5, getting 16 for a total, then Adding 16 to the whole equation would be 16/3 or x=16

A hand sanitizer was advertised to be more effective at killing bacteria than any antibacterial soap. Students were split evenly into 4 groups to test this claim. Groups 1-3 washed their hands using the assigned hand sanitizer or soap (see table) and warm water for two minutes, and then dried their hands with a paper towel. Group 4 rubbed their hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then dried their hands with a paper towel. After washing, each student’s hands were swabbed and the swab was applied to a culture plate and incubated. Finally, the bacterial cultures were counted. what is the independent variable?
Answer:
Group 4
Explanation:
The control group in this case would be those students in group 4.
The control group during an experiment is a group that does not receive the treatment administered to other groups and as such used as a standard for measuring the effects of the treatment on other groups. Whatever differences that exist between the control group and the various treatment groups is attributed to be as a result of the treatment administered to the groups.
In this case, group 4 only used warm water for washing their hands instead of the hand sanitizer/soap used by the other groups. Whatever differences found out in the bacterial count in their respective culture swabs can be attributed to the effects of the hand sanitizer/soap.

Hope This Helps.pls mark brainliestexplain why the suspension of isolated chloroplasts became alkaline when illuminated?
Answer:
Yes, protons are pumped across the membrane, but flow right back again through the ATP synthase. More important is that illumination is required for carbon fixation. As photosynthesis runs, the chloroplasts remove CO2 from the water they are suspended in. In solution, CO2 forms carbonic acid, so removing CO2 will reduce the level of carbonic acid, raising the pH.
Explanation:
Chloroplasts are the primary cell organelles involved in the conversion of light energy into stable chemical energy through photosynthesis. The chloroplasts will become alkaline due to a rise in pH and a reduction in carbon dioxide.
Chloroplast is the green-colored cell organelle, primarily involved in the conversion of light energy into chemical energy.
When the isolated chloroplasts are illuminated, the suspension in which chloroplasts are suspended becomes alkaline. It is assumed that protons are pumped in from the medium to the thylakoids.
As photosynthesis takes place, the chloroplasts remove carbon dioxide from the suspension, which causes an increase in the pH of the suspension.
Therefore, the formation of carbonic acid from the CO2 will raise the pH.
