Answer:
A. is the answer hope this helps
Mechanical waves require medium
Answer:
Option D
2 m/s East
Explanation:
From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum
Momentum, p=mv where m is the mass and v is the velocity
Since the masses are the same then
Therefore
where and are final velocities of objects while and are the initial velocities respectively
Taking East direction as positive then West as negative and by substitution
Therefore
hence East since it's positive
Answer:
False
Explanation:
False
If brakes fail then we should not run against any object or wall to slow down the speed instead we should use friction forces slow down the car and shift gear to neutral to cease any acceleration.
By driving zig-zag motion friction force on the tires may stop the car after some distance.
Do not try to shut off the engine as it will lock the steering mechanism any prove fatal.
