Answer:
Part a)
Part b)
Part c)
v = 100 m/s
Part d)
since wave is moving in +x direction
so here the sign must be negative
so complete wave equation is
Explanation:
As we know that the wave equation is given as
here we know that
= maximum displacement of the particle
Part a)
maximum displacement = amplitude
so here we know that
Part b)
k =
here we know that length of the string is 3 m
it consist of 3 loops
so we will have
so we have
Part c)
v = wave speed
v = 100 m/s
Part d)
since wave is moving in +x direction
so here the sign must be negative
so complete wave equation is
Answer:
1. False
2. Fats
3. False

MyPlate is an initiative from the United States Department of Agriculture that is designed to help Americans improve their eating habits throughout their lifetimes. Every meal matters. The five food groups represented in My Plate include vegetables, grain, dairy, protein foods, and fruits.
Calories are a source of energy for the human body. So, the more active a person is, the more energy he would need to be supplied to him in form of calories. The less active a person is, the fewer calories he would need.
