ExplanationWhen you shake a rope, the particles in the rope move up and down, and the wave moves forward or away from the source of energy. The rope moves in a direction that is perpendicular
Nodes are the places where the rope doesn't move at all; antinodes occur where the motion is greatest.
Step 1
let's check the graph:
a) Nodes
and Antinodes
so, in the ripe there are 8 antinodes
therefore, the answer is
c) 8

Answer:
7.468 kN
Explanation:
Here the force of 7468 Newton is given.
Some of the prefixes of the SI units are
kilo = 10³
Mega = 10⁶
Giga = 10⁹
The number is 7468.0
Here, the only solution where the number of significant figures is kilo
1 kilonewton = 1000 Newton
So 7468 N = 7.468 kN
