A solenoid contains 770 coils of very thin wire evenly wrapped over a length of 18.0 cm. Each coil is 0.800 cm in diameter. Part A If this solenoid carries a current of 9.00 A, what is the magnetic field at its center

d is the correct answer

battery with hi vtge high val resist in series

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

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
