Answer:
See explanation below.
Explanation:
Given two blocks of masses M and m, And a force F acting on the block of mass M pulling it outside.
The two masses system can be considered as a whole, With F being the only external force acting on them.
Here the spring force has been ignored as while considering the two system as a whole, it will be accounted as an internal force for the system
Therefore, The acceleration of the system will be:
Now both the masses are moving with this same acceleration towards the direction of force
.
Acceleration of mass m = a (as the system is moving as a whole)
Force on the mass m= mass times acceleration.
Tap water isn't pure. it just isn't H₂O.
A wheely because you see when you push it it has the scwers stong
Missing graph. I attach it in the answer.
In a uniformly accelerated motion, the velocity at time t is given by:
where a is the acceleration and t is the time.
Given the previous equation, if we plot v(t) versus t, we find a straight line; moreover, a (the acceleration) represents the slope of the curve.
Looking at the graph, we see that when the time goes from 10 s to 20 s, the velocity increases from 4 m/s to 6 m/s. Therefore the slope of the curve is
and this corresponds to the acceleration.
So, the correct answer is <span>
0.2 m/s2.</span>
Answer:
When boiling water is poured into a thick tumbler its inner surface expands. However, due to low thermal conductivity of glass, the expansion of outer surface of the tumbler is quite small. Due to uneven expansion of the outer and inner surfaces, the tumbler breaks.
