LIST THE 5 TERMS WHEN MEASURING WAVELENGTHS?

What are the 4 measures of a wavelength?

As an example, a wave with a period T = 0.25 s takes ¼ of a second to complete a full vibration cycle (crest – trough – crest) at a certain location and thus performs four vibrations per second. Hence its frequency is f = 4 Hz.

...

1.2 The measures of a wave: velocity, amplitude, wavelength and frequency.

Explanation:

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

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
