1.at constant temperature a gas occupy 50cm³ at 10mmhg calculate the work done 2.if normal human body temperature is 34 °c, what is the equivalent value in fahrenheit

3. A stone is thrown upward from ground with a velocity of 40m/s. how long does it take to reach the highest point
​

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
