The stopcock connecting a 4.94 l bulb containing krypton gas at a pressure of 7.24 atm, and a 2.78 l bulb containing argon gas at a pressure of 2.35 atm, is opened and the gases are allowed to mix. assuming that the temperature remains constant, the final pressure in the system is: atm.

c) up is the direction the magnetic force is acting on the charge.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
