Answer:
10 kg
Explanation:
Assuming a frictionless surface, then force F=ma where F is the applied force, m is the mass and a is acceleration. Making m the subject of the formula then
Substituting 100 N for the applied force F and 10 m/s^2 for acceleration a then the value of m will be
Therefore, in terms of kilograms, the bookshelf weighs 10 Kg
Answer:
Here is an image attached with similar questions.
The correct answer is D where acceleration is function of time.
Explanation:
The force acting on the object is constant.
There is no change in the application of forces.
And we know that Force is the product of acceleration and masses.
Newtons second law:
Regarding mass we know that it can neither be created nor destroyed.
So in we have two constant terms, constant divided by constant will give the same result as
There is no change in acceleration with respect to time
.
So the most appropriate graph where time (t) is changing on but acceleration doesn't changes is D.
The graph will be similar to and will be horizontal to the
.
Option D depicts the same.
