No, flexeril is a muscle relaxant. The drug name is cyclobenzaprine. Ibuprofen is a non-steroidal anti-inflammatory pain medicine. You can safely take a pain reliever and a muscle relaxant together. They work together to help reduce your discomfort.
This force exerted by air molecules or what is called as Atmospheric pressure is measured by barometer. At sea level the amount of pressure exerted by the atmosphere is about 14.7 pounds/square inch. This means at sea level an object experiences 14.7 pounds of pressure pushing against every square inch of object. When heat energy is added to molecules, they begin to move rapidly. This causes the molecules to exert increased pressure as they bump into the objects around them.
Standard atmospheric pressure for Earth sea level (14.7 psi) 150 to > 550 kPa: 25 to > 80 psi: Impact pressure of a fist punch (approximate) [citation needed] +180 to +250 kPa +26 to +36 psi: Air pressure in an automobile tire relative to atmosphere (gauge pressure) [citation needed] +210 to +900 kPa +30 to +130 psi
