2) Unbalanced. Mike will push the box with a force of 20 N. The forces would be balanced if the box responded with 30 N.
3) Balanced. Both boys are pulling with the same force. Neither is winning.
4) Unbalanced. The rope will move with 10 N to the west. The teachers are winning.
5) Unbalanced. The kids are pulling 220 N to the east. The kids are winning.
6) Balanced. You and the dog are pulling with the same force.

Key Takeaways: Isotopes
Isotopes are samples of an element with different numbers of neutrons in their atoms.
The number of protons for different isotopes of an element does not change.
Not all isotopes are radioactive. Stable isotopes either never decay or else decay very slowly. ...
When an isotope decays, the starting material is the parent isotope.

Answer:
W = 113.98 N
Explanation:
Given that,
Radius of Potatoine
Mass of Potatoine, 
Mass of Marvin, m = 35 kg
We need to find his weight on Potatoine. Weight of an object is given by :
W = mg
g is acceleration due to gravity, 
So,
So, his weight on Potatoine is 113.98 N.
Answer:
Explanation:
distance travelled
s = 2πR
= 2 X 3.14 X 140
= 880 m
final velocity = v
initial velocity = u
distance travelled = s
time = 60 s
s = ut + 1/2 at²
880 = .5 x a x 60²
a = .244 m/s²
final velocity v = at
= .244 x 60
= 14.66
centripetal acceleration at final moment
v² /R
14.66 X 14.66 / 140
= 1.53 m/s⁻²
1.53 m/s²
this is centripetal acceleration which acts towards the centre.
tangential acceleration calculated a _t = .244
redial acceleration ( centripetal ) = 1.53
Resultant acceleration
R²= 1.53² + .244 ²
R = 1.55 m/s²
total force = 1.55 x 76
= 118 N
