The given mass is 0.025563 g.
Examine the given choices.
a. 0.026 g
This uses 2 significant digits, with rounding to the 3rd decimal place.
b. 2.5 x 10² g = 250 g.
It is incorrect.
c. 0.025 g.
This uses 2 significant digits. It is inaccurate because it does not use rounding to the 3rd decimal place.
d. 0.02 g
This uses one significant digit. It is incorrect for representing the given data.
Answer: a. 0.026 g

Answer:
.D)The Vector sum of the linear momenta of the fragments must be zero.
Explanation:
.D)The Vector sum of the linear momenta of the fragments must be zero.
This statement is true. This is so because no external force is acting on the masses. The motion is created by internal force so momentum of fragments will be conserved.
A) this statement is false because kinetic energy was zero in the beginning ( the bomb was stationary in the beginning )
B ) This statement is false because it violates the law of conservation of momentum .( it does not violates only when all the fragments have equal mass )
C ) This statement is zero because kinetic energy is not a vector quantity so two kinetic energy when added can not sum up to zero.
