Answer:
the answer is OD which says tge buoyant girce on an object is equal to the weight of th fluid
Explanation:
The difference in frequency can be calculated using the formula
f= source frequency from the ship
v'= speed of the wave reflected from the whale = 4.95 m/s
v= speed of the ship.
since, the source frequency and speed of the ship data is missing, calculation of difference in frequency not possible.

The angle measured counterclockwise from the positive x-axis is θ = 50.4°
<h3>
How to get the angle correspondent to a vector?</h3>
Here we know that the vector is:
V = < -177 cm, -214 cm>
To get the correspondent angle for this vector, we can think that this is the hypotenuse of a right triangle, such that the y-component and x-component are the cathetus.
Then, to get the angle (measured counterclockwise from the positive x-axis) is given by:
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
Tan(θ) = (-214cm)/(-177 cm)
Using the inverse tangent function we get:
Atan(Tan(θ)) = Atan((-214cm)/(-177 cm))
θ = 50.4°
So the angle is 50.4°

<h3>The correct answer is:</h3><h2>9.08 x 10⁶ meters.</h2><h2 /><h3>Explanation:</h3>
Fg = 2.58 x 10³ N
Mv = 4.87 x 10²⁴ Kg
Md = 655 Kg
So, Fg = G Mv Mp / r²
By putting in the values,
r² = 8.2466 x 10¹³
<h2>r = 9.08 x 10⁶ meters.</h2>
