Equilibrium is when the opposing forces or influences are balanced. So it would be E!
Answer:
The value of speed of wooden block at the instant after the collision
262.41 
Explanation:
Given data
Mass of block = 6.3 kg
Mass of bullet = 0.086 kg
Velocity of bullet
= 266 
Final velocity of whole system is

Put all the values in above formula we get

262.41 
This is the value of speed of wooden block at the instant after the collision.
Answer:
This show the most stable of atom of that element
Explanation:
The mass number of a element on the periodic table show the most stable atoms of that element.
The guy below is wrong!
F=ma
Where force = mass x acceleration
We dont have acceleration, a= change in velocity divided by the time taken.
a = v (final velocity) - u (initial) / t
a us 8-0 (at rest means u was 0) / 20 = 0.4
Using F=ma
F= mass x acceleration
F= 4 x 0.4
F=1.6 N
Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
