Wavelength = (speed) / (frequency)
Wavelength = (330 m/s) / (1320/s)
Wavelength = (330/1320) m
Wavelength = 0.25 m
<em>Wavelength = 25 cm</em>
<h2>
Option A is the correct answer.</h2>
Explanation:
Here velocity of ball and bat are in opposite direction.
Velocity of ball = 40 m/s
Velocity of bat = 18 m/s
Since they are in opposite direction relative velocity is given by,
Relative velocity = 40 + 18 = 58 m/s
Distance to home plate = 18 m
We have
Displacement = Velocity x Time
18 = 58 x Time
Time = 0.3 seconds
Option A is the correct answer.
Answer:
Those are the best electricity conductors that we can use to span large distances with large amounts of power. Its also alot cheaper to use copper wire than other kinds of metals. not to mention copper can bend easily and that makes the job of putting on wires alot faster and easier.
