Answer:
I think the answer would be British Thermal Unit
Explanation:
It equals one degree Fahrenheit and the equation for it is 1.055 × 103 joules.
The period of the wave is the reciprocal of its frequency.
1 / (5 per second) = 0.2 second .
The wavelength is irrelevant to the period. But since you
gave it to us, we can also calculate the speed of the wave.
Wave speed = (frequency) x (wavelength)
= (5 per second) x (1cm) = 5 cm per second
Answer:
Explanation:
a) Total distance traveled by the whale = 6.9 km + 1.8 km + 3.7 km = 12.4 km
b) the magnitude and the direction of the displacement of the whale = 6.9 km due east - 1.8 km due west = 5.1 due east
it final displacement = 5.1 km due east + 3.7 k due east = 8.8 km due east
c) average speed in km / hr = total distance traveled / total time = 12.4 km / 0.5 hr ( 30 min/ 60 min × 1 hr) = 24.8 km / hr
d) average velocity in km / h = total displacement / total time = 8.8 km / 0.5 h = 17.6 km/h
The one in the water would have a much greater speed than the one in the air since energy is transmitted better and faster in liquid than gas.
