Answer:
Part (a) - 1.42 rev/s
Part (b) - 5.78s
Part (c) - 6.90s
Part (d) - 33.81 rev
Explanation:
The solution to this problem requires the knowledge of constant angular acceleration motion. The equations used here are similar to those used in constant linear acceleration motion. The detailed solutio is presented in the attachment below.
A=2.5 m/s²
m= 100 Kg
F=m*a
F=force
m=mass
a=acceleration
F=100 Kg*2.5 m/s²=250 N
answer: F=250 N
Answer:
Twice.
Explanation:
The momentum of an object is given by :
p = mv
Where
m is mass and v is the velocity
If the mass of the ball were doubled, m'=2m and v'=v=3 m/s
New momentum,
p'=m'v'
p'=2m × v
p'=2mv
or
p'=2p
So, the new momentum becomes twice the initial momentum.

Explanation:
The liquid contains only one element. -The liquid is a pure substance. The number at the end of an isotope's name is the -mass number. While looking at xenon (Xe) on the periodic table, a student needs to find an element with a smaller atomic mass in the same group.
