It occurs as detrital grains in sedimentary rocks. It forms under extreme pressure.
The answer is B. Bye because B those study speed.
Answer:
The dog is moving at a constant speed
Explanation:
Given that,
Position : 5, 10, 15, 20, 25
Time = 5. 10, 15, 20, 25
We need to draw a position time graph
Using given data
A graph of position and time shows the speed.
According to graph,
The graph indicates that the dog is moving at a constant speed because the graph is straight line.
Hence, The dog is moving at a constant speed
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.
