Answer:
The answer is mutualism because they are both on the receiving and giving ends
Answer:
Option D, The equator gets more direct sunlight throughout the yea
Explanation:
The position of the mass is given by (in cm):

The velocity is the derivative of the position:

Substituting t=0.40 s, we can find the velocity at this time:
A=atomic mass
Z=atomic number (nº of protons).
N=neutons.
A=Z+N
Data:
A=39
Z=19
A=Z+N
39=19+N
N=39-19=20.
It therefore has 20 neutrons in its nucleus.

Below is the solution:
<span>centripetal accel = 1.5*g
ω²r = 1.5*9.8m/s²
ω² * 8m = 14.7 m/s²
ω = 1.36 rad/s * 1rev/2πrads * 60s/min = 12.9 rpm</span>
