Since the angle is West of North, therefore to find for
the westward component (horizontal component) of the vector, we use the sin
function:
sin θ = opposite side / hypotenuse = westward component /
resultant vector
So the westward component (x) is:
x = 85.42 sin 23
<span>x = 33.38 unit</span>
Answer:
2 m/s²
30 m/s
Explanation:
1) F = ma
1000 N = (500 kg) a
a = 2 m/s²
2) Given:
v₀ = 0 m/s
a = 2 m/s²
t = 15 s
Find: v
v = at + v₀
v = (2 m/s²) (15 s) + 0 m/s
v = 30 m/s
It's Decrease or cease to exist, but I'm leaning more towards decrease.
Answer:
147.45 Hz
Explanation:
v = Speed of sound in water = 1482 m/s
= Speed of whale = 4.95 m/s
Frequency of the wave in stationary condition
Ship's frequency which is reflected back
The difference in frequency is given by
The difference in wavelength is 147.45 Hz
