A boat has a pressure difference between top and bottom of 100 N/m2.
The area is 5 m2.
What is the weight of the boat ? N
How is the upthrust = N

If a 500 N child climbs in the new pressure = N/m2.

According to the tide table below what time of day will the highest tide occur?

The goal of this experiment was to answer the question, "how does diffraction occur? " suppose you formulated this alternate hypothesis: if the gap width is increased while keeping wavelength constant, then the observed diffraction will decrease because the less the ratio between wavelength and gap width is, the smaller the observed diffraction angle will be.to test this hypothesis, you would change the  gap widthdiffraction anglewavelength  and observe the  gap widthdiffraction anglewavelength  in the system.therefore, the independent variable would be the  gap widthdiffraction anglewavelength  and the dependent variable would be the  gap widthdiffraction anglewavelength.
