Aforce or an event that changes the earth's surface is known as a. a tectonic boundary b. an oceanographic change c. a geological process d. a geologic plate

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

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
