<span>Here's your explanation:
R = k / d^2 (k is a constant, unknown)
</span><span>d1 = 0.01 and R1 = 0.306
d2 = 0.0299 R2 = ?
</span>
<span>Use the equation in line 1 for both case and divide and k will go away and you can find R2</span>
<em><u>Answer:</u></em>

<em><u>Resultant velocity is the vector sum of all given individual velocities. Velocity is a vector because it has both speed and direction. There are many ways to calculate vector sums, such as using a vector addition diagram, but using trigonometry to calculate vector components is usually more efficient.</u></em>

Answer:
V=11.74m/s, 69.59°
Explanation:
From newtons equation of motion ,we know that
V^2 = u^2+2gh
for the rt
For the vertical component of the speed
Vy^2=V0^2+ 2gh
Vy= the final speed in the vertical axis
V0= initial speed, 0m/s
g= acceleration due to gravity 9.81m/s
h=height/distance between the eagle and the lake
Vy^2= 2*9.81*6.2
Vy =√121.644
Vy=11.02m/s
The resultant speed will be
V=(Vy^2+Vx^2)^0.5
V=(11.02^2+4.1^2)^0.5
V=137.7241^0.5
V=11.74m/s
Direction
Tan^-1(11.02/4.1)
β=69.59°
V=11.74m/s, 69.59°
Answer =11.74m/s, b°
Its a compound hope this helped u<span />
