WILL GIVE , PLS HELP IT DUE TODAY Lab Report
Drop and Bounce
u have to drop a bouncy ball from different points of a ruler or something like a ruler and then have to write down stuff for this, I don't know what to do though I'm freaking out will give and 100 points
1. What was the purpose of the experiment?

2. What were the independent, dependent, and control variables in your investigation?

3. Write a hypothesis based on observations and scientific principles.

Experimental Methods
1. What tools did you use to collect your data?

2. Describe the procedure that you followed to conduct your experiment.

Data and Observations
1. Record your observations. Include the data table you created for the lab and a graph based on the data table.

Conclusions
1. What conclusions can you draw about the relationship between the temperature of a ball and its bounce height? Is there a direct or inverse relationship? Write an evidence-based claim.

2. What are some sources of error in your experiment? What are some ways that you could improve the accuracy and precision of the measurements?

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

Many bird species build nests in which they raise their offspring. one of these species is known as the magnolia warbler. breeding pairs of magnolia warblers build nests out of pieces of grass and twigs. the female warbler will then lay her eggs in the nest and sit on the eggs for a few weeks until they hatch. after the offspring have hatched, the female will continue to sit on the newborn chicks to keep them warm. both the male and the female bring food for the offspring to eat until the young are mature enough to find food on their own. which of these most likely describes why birds such as the magnolia warbler build nests in which to raise their offspring? a. nest building decreases the amount of energy used by the parent birds to raise their offspring to adulthood. b. nest building increases the probability that the offspring will survive and eventually produce offspring of their own. c. nest building decreases the amount of food that the offspring require the adult birds to provide. d. nest building increases the probability of the offspring being located by airborne predators.
