calcululate the molality of CsCl in a 8% by mass aqueous solution. answer in units of m
A 27-pound meteorite struck a car in Peekskill, NY, creating a dent about 22 cm deep. If the initial speed of the meteorite was 550 m/s, what was the average force exerted on the meteorite by the car?
A gaseous mixture of O2 and N2 contains 30.8 % nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 365 mmHg?
the pressure on a gas at-73 Cis doubled, but its volume is held at constant. What will the final temperature be in degrees Cesius?
i have to questions that just need to be checked on to see if i got them right. Lim x-->infinity for both problems 10/x+10 is number one i got 0 for this one. or is it does not exist. lim x-->infinity 6x/6x+5 for this one I got One. (1) is that correct.??
easy cal Q
Thanks! Exactly what I was looking for.
easy cal Q
lim x--->a x^2+a^2/x+a I know this equals (a) but I dont know how to explain my answer.
A) m*v^2=kinetic energy m*72^2=7.6*10^7 m*(7.6*10^7)/(72^2)=14660.5kg B) p=w/t p=(7.6*10^7)/2=3.8*10^7 p=38000000 watts
