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.
Insulators are the materials that are bad conductors of heat/electricity.insulation is tge pricess of covering any thing with such materials in order to prevent heat or electricity.
The two types of mechanical waves are longitudinal waves, and transversal waves.

Total distance covered = 40+20+30 = 90 km
Total time taken to cover this distance = .5 hr + .2 hr + .75 hr = 1.75 hr
Avg. speed of Trip would be
90/1.45 = 62.07 km</span>
Answer:
The correct equation for calculating force is change in momentum divided by time. So 10 kg m/s divided by 3 s is 3.3 newtons (N
