Answer:
60cm
Step-by-step explanation:
perimeter of a square=4L
192cm=4L
L=48cm
Dilated by ratio 0.25
1 : 0.25 = 48 : 12
New length = 48+12 = 60cm.
Answer:
it might be 3 one according to me
The statement that best describes the blocks after the spring is released is the total momentum is zero.
<h3 /><h3>Law of conservation of momentum</h3>
From the law of conservation of momentum, the initial momentum of the system, M equals the final momentum of the system M'
M = M'
<h3>
Momentum of blocks</h3>
Now, since both blocks are initially at rest, the initial momentum M = 0.
Since the initial momentum equals the final momentum after the blocks are released,
M = M' = 0
So, the total momentum after the blocks are released is zero.
So, the statement that best describes the blocks after the spring is released is the total momentum is zero.
