pressure=weight/area
a) the total weight means, 1.01*105 kg
hence, pressure= 1.01*105 kg/ 1 m2
hence, pressure = 1.01*105 kg/m2

the answer 4.9 was wrong I'm
not sure what I did wrong
1) A cubic metal box with sides of 18 cm contains air at a pressure of 1 atm and a temperature of 280 K. The box is sealed so that the volume is constant, and it is heated to a temperature of 380 K. Find the force due to the internal air pressure on each wall of the box 4.9 You currently have 1 submissions for this question....

I got a right but I got two wrong
Balloons are still used to deploy sensors that monitor meteorological phenomena and the chemistry of the atmosphere. It is to investigate some of the technicalities of ballooning by using the perfect gas law. Suppose your balloon has a radius of 1.5 m and that it is spherical. (a) What amount of H2 (in moles) is needed to infate it to 1.0 atm in an ambient temperature of 25'C at sea level?...

I got b wrong, not sure why :(
An electron moves in a circular path with a speed of 1.35 x 10 m/s in the presence of a uniform magnetic field with a magnitude of 2.16 mT. The electron's path is perpendicular to the field. (a) What is the radius (in cm) of the circular path? Cm (b) How long (in s) does it take the electron to complete one revolution? Consider the result for the radius, and how it...
