Answer:
<h2>b) 3.48 N approx.</h2>
Step-by-step explanation:
<em>The bird will experience a centripetal force, this is the force exerted on a body that moves through a curve path.</em>
Fc=centripetal force
m=mass
v=velocity
r=radius
Step one:
given data
mass of bird m=0.3kg
the radius of curve r= 20m
velocity v= 15 m/s
Substituting we have
<u>The force is 3.37N</u>
Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

Answer:
23
Step-by-step explanation:
25+22+21+23+24= 115
115/5 = 23.
Answer 121°
Step-by-step explanation:
All triangles have an interior angle sum of 180.
From this you can subtract 103 and 18 to get 59.
The line that r is connected to is 180° (hence being a line)
This means you can subtract 59 from 180 to get 121°
