Answer:
The frequency of an ocean wave is 15 Hz.
Explanation:
We are given with, the speed of an ocean wave is 45 m/s. Its wavelength is 3 m
It is required to find the frequency of an ocean wave.
The speed of a wave is given in terms of frequency and wavelength as :
,
f = frequency of ocean wave
So, the frequency of an ocean wave is 15 Hz.
a) precise but not accurate.
this is because the thrower was capable to repeat the same result everytime but it was not the desire outcome.
Answer:
4.04 s
Explanation:
h = vi + 1/2 a t ^2
HERE h = 80 m , vi = 0 , a =9.81 m/s^2
80 = 0 + 1/2 × 9.81 × t ^2
80 = 4.905 t^2
t^2 = 80/4.905
t ^2 = 16.30988
t = square root of 16.30988
t = 4.0385 s
t = 4.04 s
At sea level water boils at 100 degrese celcius
it can travel by curved pipe by reflecting
