Plants are autotrophs
Animals are heterotrophs
Answer:


Explanation:
A denotes Alex
M denotes Mary
r = Distance from center
Mary and Alex will have the equal displacements in equal interval of time as they are in uniform circular motion. So,

Tangential speed speed is given by

The tangential speed of Mary is 
Answer:
A.3.64 m
Explanation:
Because
- v=(fλ)
- (1382)=(380)λ
- λ=3.637m~3.64m
<em>where</em><em> </em><em>,</em><em>v</em><em>=</em><em>velocity</em>
<em>f</em><em>=</em><em>frequency</em><em> </em>
<em>λ</em><em>=</em><em>wave</em><em> </em><em>length</em><em> </em>
Answer:

Explanation:
means initial angular velocity, which is 0 rev/min
means final angular velocity, which is 
t means time t= 3.20 s
one revolution is equivalent to 2πrad so the final angular velocity is:
= (2π/60) *2.513*10^{4} rad/s
= 2628.5 rad/s
so the angular acceleration, α will be:
α = 2628.5 rad/s / 3.20 s

so the rotational motion about a fixed axis is:
+ 2αΔTita where ΔTita is the angle in radians
so now find the ΔTita the subject of the formula
ΔTita =
