You are given a rectangular block of an unknown resistive material which is 1.0 cm high by 4.0 cm wide by 6.0 cm long. You measure a resistance of R when electrodes are connected to the top and bottom of the block in order to measure resistance across the height of the block. What is the correct sequence of resistance values that you will measure when the resistance is measured across the height of the block, the width of the block, and finally the length of the block

answer: pseudoscience

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 100. i just did this lesson and got a 100% on it. : )
