False. I’m pretty sure the heart is the strongest muscle ( ._.)
Hello There!
From what i know, gravitational force increases if the mass is increased.
If the mass is being decreased, then i assume it will be B. Decreases.
Hope This Helps You!
Good Luck :)

Answer:
a) Impulse(J)=40.04 kg.m/s
b)F=2566.66 N
Explanation:
Given that

We know that impulse(J) impulse is a vector quantity

We know that P=mV
So
Now by putting the values
J=1.3(9.8-(-21))
So impulse(J)=40.04 kg.m/s
Force is given as

or we can say that

So 
F=2566.66 N
When a body performs a uniform circular motion, the direction of the velocity vector changes at every moment. This variation is experienced by the linear vector, due to a force called centripetal, directed towards the center of the circle that gives rise to centripetal acceleration, the mathematical expression is given as,

Where,
v = Tangential Velocity
r = Radius
The linear velocity was 2010m/s in a radius of 0.159m, then the centripetal acceleration is


Therefore the centripetal acceleration of the end of the rod is 
It can be classified with either the alkali metals or halogens; i believe
