What methods are you using to test this (or each) hypothesis theses are my hypothesis:

1) Experiment of motion( movement) can be performed in this lab.

2) Experiment of motion( movement) can be performed better in this lab.

3) Only experiments of motion( movement) can be performed in this lab.

4) Experiment of motion( movement) can be performed more accurately in this lab.

5) No experiment of motion( movement) can be performed in this lab.

I'm kinda on a crunch of time so please help me as fast as you can but still being accurate

Why is metal often used for cooking pan?

On mars a rock falls an unknown vertical distance from a resting position and lands in a crater. if it takes the rock 2.5 seconds to fall, how high is the cliff the rock fell from? mars' surface gravity is 3.8 m/s2. a. 9.5 m b. 11.9 m c. 15.2 m d. 23.8 m

Industrial processes often require the damping of vibrations. consider a workbench that uses four large ideal springs in place of traditional legs, with each spring supporting one corner of the workbench and exhibiting a force constant of 47500 n/m. this workbench is used when creating products that involve highly unstable chemicals. according to specifications, the acceleration of the manufacturing equipment must be held to less than 22.3 m/s2 for the manufacturing process to proceed safely. the amplitude of vibrations are expected to remain under 0.622 mm throughout. given that the workbench and maufacturing equipment combine to 6.05 kg, find the maximum acceleration expected of the equipment and workbench. (ignore the mass of the springs.)
