Complete the passage to summarize factors affecting the speed of a wave. The material or substance that a wave moves through is called a . The medium affects the speed of the wave that passes through it. One factor that affects the speed of a wave is the of medium. Some waves move faster in solids and some waves move faster in liquids and gases. Another factor that affects wave speed is the of the medium.

i think the answer is a, hope this : )

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

i would say

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
