iron is magnetised
but how did u calculate acceleration when time is not given
acceleration =velocity /time
oh sorry i thoughr 50 was acceleration
hmm that was i saying
no problem
ho jata h
the answer will come in terms of time
I can't understand
we know acceleration is v-u/t so u is 50 so u have to specify v and t 2 get the answer

Answer:
D. All of these
Explanation:
Acceleration is the rate of change in velocity which is positive. Hence, the velocity increases. Hence, the speed always increase. If a body having a certain mass is accelerated it experience a force. According to Newton's second law of motion
Hence, if the body experience some force as well as some of change in velocity there will always be some change in linear momentum. As, v increases the linear momentum also increases.
