Part A. Use the horizontal ruler to measure the horizontal distance between two crests. What is this distance? _ This is the wavelength of the wave. part B. What is the distance between the two troughs?

less than one you can't create energy

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

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
