Assume the snow is uniform, and horizontal.
Given:
coefficient of kinetic friction = 0.10 = muK
weight of sled = 48 N
weight of rider = 660 N
normal force on of sled with rider = 48+660 N = 708 N = N
Force required to maintain a uniform speed
= coefficient of kinetic friction * normal force
= muK * N
= 0.10 * 708 N
=70.8 N
Note: it takes more than 70.8 N to start the sled in motion, because static friction is in general greater than kinetic friction.
The correct answer that would best complete the given statement above would be the term WHITE. Prisms separate WHITE light, such as that from the Sun, ...
Answer:
angular frequency of the table must be same as the frequency of the projection of the gum on the wall
Explanation:
Since we know that the projection on the wall is the vertical component of the position of the gum on the rotating table
So here we will say

so the angle made by the radius vector depends on the angular frequency of the disc by which it is rotating
So we can say

so here we can say

so here we can say that
angular frequency of the table must be same as the frequency of the projection of the gum on the wall
