The centripetal acceleration is the ratio of the tangential speed and the
radius of the shell.
The tangential speed of the part of the shell is approximately <u>0.12961 m/s</u>
Reasons;
The widest diameter of the egg, d = 12 cm = 0.12 m
The given centripetal acceleration, 
= 0.28 m/s²
Required:
The tangential speed of the bird.
Solution;
Where;
v = The tangential speed
Which gives;
v² = 0.28 m/s² × 0.06 m = 0.0168 m²/s²
v = √(0.0168 m²/s²) ≈ 0.12961 m/s
The tangential speed, v = <u>0.12961 m/s</u>

I believe this is right-
for the first question, it should be fluffy
and for the second it should be spot
potential energy is unused
kinetic energy is being used
it would be appropriate to round a number when you are talking about people or animals. Ex. it fits 10 1/2 people. it will most likely fit 9-11 people.
You it is not appropriate to round with money.
Ex. If you owe someone $9.43 you don't just give them $9
<u>Answer:
</u>
Distance traveled = 70 meters
Displacement = 36.06 meters
<u>Explanation:
</u>
Let north be positive Y and east be positive X
10 meters north, displacement = 10 j meters
20 meters west, displacement = -20 i meters
40 meters south, displacement = -40 j meters
Total displacement = (10 j - 20 i – 40 j) meters = (- 20 i - 30 j) meters
Magnitude of displacement = 
Distance traveled = 10+20+40 = 70 meters
Answer:
a)
b)
c) 0 J/K
d)S= 61.53 J/K
Explanation:
Given that
T₁ = 745 K
T₂ = 101 K
Q= 7190 J
a)
The entropy change of reservoir 745 K
Negative sign because heat is leaving.
b)
The entropy change of reservoir 101 K
c)
The entropy change of the rod will be zero.
d)
The entropy change of the system
S= S₁ + S₂
S = 71.18 - 9.65 J/K
S= 61.53 J/K
