A physics laboratory situated at an elevation of 1500 m wishes to shield against cosmic rays. What thickness of concrete (density= 1700 kg/m³) is required on the roof to give the same weight per square meter as 1500 m of air? Ignore any change in air density with altitude. i Save for Later m Submit Answer

the average density of an atom is approximately 103 kg/m3. The nucleus of an atom has a radius about 10-5 times that of the entire atom, and contains nearly all the mass of the atom.  What is the approximate density, in kilograms per cubic meter, of a nucleus?

Although human lung capacity is about 3 liters per lung, the tidal volume, representing the amount of air that is breathed in and out with each breath is much -3 less, typically about 250 cm7 per lung. The cycle of inhalation and exhalation during normal activity can be represented as a sine curve, as shown in the figure below, where the amount of air in each lung before inhalation begins is about 1.09 liters (the functional residual capacity of the lung) and the time on the horizontal axis has been calculated with the average adult breathing rate of 16 breaths per minute. Volume of air in lungs (L) 1.34 1.09 mm minimum height maximum height 15 We can model each lung as a cylinder of radius 5.95 cm in which one end cap is free to move up and down, increasing and decreasing the volume of the model lung during the breathing process. (a) Using the data above, calculate the minimum and maximum heights (in cm) of the model lung during the breathing process. (Round your answers to at least…

Convert the total number of gallons of gas  2.90 per gallon (round trip 452 miles) to liters of gas.

Please help me with these problems. We are using algebra based physics, not calc based

For (b), why do we divide the (100Wx8h) by (103Wh)? I get that we need to cancel out the Wh, but why do we divide by 103 specifically?

Hey, I'm really so sorry for leaving this out, but I completely forgot to tell you that I need the answer in the amount of years it takes. That's totally on me, I apologize. Also, I can't tell if the dot between the two 2s in the answer is a multiplication symbol or a decimal point.
