There are several main pieces of evidence<span> that support the </span>Big Bang<span> theory. One is the fact that the universe is expanding, proven with something </span>called<span>red shift. The second is something </span>called<span> cosmic microwave background radiation. The third is the abundance of different elements in the universe.</span>
Answer:
The normal force is 85,42 N
Explanation:
There is no friction force, therefore there is no relationship between the normal force and the friction.
We can find the normal force using a free body diagram and check the forces that are acting on the sled. The total forces are equal to 0 because there is no movement in the y-axis. The movement exists only on the x-axis.
Answer:
Weight is a consequence of the universal law of gravitation
Explanation:
Weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. Weight is a consequence of the universal law of gravitation: any two objects, because of their masses, attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
