What distinguishes a nebula and a star is that a nebula is a cloud of gas and dust in outer space, visible in the night sky either as an indistinct bright patch or as a dark silhouette against other luminous matter. And a star is a<span> type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.</span>
Yes. If an object would be vertical, it would most likely have potential energy due to gravity.
Answer:
Any force greater than 24.5 N
Explanation:
To find the frictional force is the 1st step. this can be found by multiplying the coefficient of friction and the normal force. normal force can be found by multiplying gravity (we will say 9.8 m/s/s) and the mass which is 10. You then multiply the result by the coefficient of friction which is 0.25 and it leads us to an answer to 24.5 N. This means that if you pull with exactly 24.5 N, the sled wouldnt move. So you need a force greater than 24.5 N and we have our answer.
I hope I helped correct me if im wrong
because there small elemts like atoms but bigger than atoms we all know that
Answer:
Net force, F = 7 N
Explanation:
It is given that,
Initial kinetic energy of the car, 
Final kinetic energy of the car, 
Distance, d = 1 m
We need to find the average net force on the car during this interval. It is given by using the work energy theorem as :


Also, W = F.d d = distance and F = net force



F = 7 Newton
So, the average net force on the car during this interval is 7 newton. Hence, this is the required solution.
