Answer:
<em>The net force acting on the object is 0 N</em>
Explanation:
<u>Newton's Second Law of Forces</u>
The net force acting on a body is proportional to the mass of the object and its acceleration.
The net force can be calculated as the sum of all the force vectors in each rectangular coordinate separately.
The image shows a free body diagram where four forces are acting: two in the vertical direction and two in the horizontal direction.
Note the forces in the vertical direction have the same magnitude and opposite directions, thus the net force is zero in that direction.
Since we are given the acceleration a =0, the net force is also 0, thus the horizontal forces should be in equilibrium.
The applied force of Fapp=10 N is compensated by the friction force whose value is, necessarily Fr=10 N in the opposite direction.
The net force acting on the object is 0 N
Answer:
first law: an object remains in uniform motion except an external force has acted upon it eg a ball in stable motion doesn't move until one moves or kicks it
second law:the body acted upon by an external force gains a momentum which is directly proportional to the applied force and acts in the direction of the force
third law: to every action there is an equal and opposite reaction eg if u push someone the person moves backward away from you and not towards you
<span>When looking at nuclear masses we speak of the processes nuclear fision and nuclear fusion. </span>In fission a nucleus breaks up, into two nuclei. In fusion on the other hand two light nuclei combine to form one heavier nucleus. The relation
E=m*c^2. explains the difference in masses. <span>
So, in case of nuclear fusion t</span><span>he mass of the parts is always </span>more than the mass of the whole when looking at nuclear masses. In case of nuclear fusion. And in case of nuclear fision, the mass of the parts is always less<span> than the mass of the whole when looking at nuclear masses. In case of nuclear fusion</span>
B.Because you cant pull out whenever you want just because you have the right away. Hope this helps.
When viewing an object through a convex lens, the object appears smaller. Thus, B. things look smaller than they actually are. The way that light bends as it passes through a convex lens results in these shrunken images; moreover, the image of a convex lens is also upside down.
