Answer:
m = 0.255kg
Explanation:
from the formular of a mass - spring system
T = 2π√m/k
making m as the subject of formular
m = T² k/4π²
T =5.91s
k = 0.288 N/m
m = 10.059/39.489
m = 0.255kg
Answer:
0.018 N
Explanation:
From the given information;
We understood that A and C possess the same current direction, thus the force between them is said to be an attractive force.
Also, between B and C, there exist different current directions, thus, the force between them is said to be a repulsive force.
So, the force per unit length magnitude are as follows:
Similarly;
Thus, the net force acting on 4.0 - m length of the wire C is:
Thus, the magnitude of the force on a 4.0-m length of wire C = 0.018 N
The mechanical advantage is defined as the ratio between the load (output force) and the effort (input force):
for the ramp in our problem, the output force is 300 N, while the input force is 100 N, so the mechanical advantage of the ramp is:
