Answer:
Its acceleration is certainly negative.
Explanation:
- When an object moving in a straight line decelerates then its velocity certainly decreases.
- Its acceleration is certainly negative.
- As we know that acceleration is the rate of change in velocity and the object is decelerating i.e. its velocity is reducing with time.
where:
are final and initial velocities of the object
are final and initial time of observation.
- Its SI unit is
This would be called elevation
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Explanation:
Answer:
50N
Explanation:
the net force is the addition of all forces in an object.
The frictional force is the opposite of the applied force, so:
Nf(net force)= 250(applied force)-200(frictional force)
so Nf=50N
Small organism are not held by anything except their size. For example if you throw an elephant and an ant of a 100m tall building the elephant would explode when he would reach the ground, as for ant it would be stunned for about 1 - 3 seconds and then move on like nothing happened. The point is for every size there is a new world.
