3-the-lamps are connected in parallel. The first lamp has a current of 2.A. The second lamp has a voltage equal to 10V and a resistance equal to 6 Ohm. The
third-lamp has a current equal to 4A Find in this scheme the total voltage, the current
for all·lamps, the total resistance.

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

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
