Answer:
0.8067 m
69.696 N
Explanation:
m = Mode = 3
M = Mass of string = 4 g
f = Frequency = 180 Hz
l = Length of string = 121 cm
Length of the string is given by

The wavelength is 0.8067 m
Linear density is given by

Speed of the wave

Speed of wave is given by

Tension is given by 69.696 N
Answer:
Easterly waves
Explanation:
Easterly is a migratory wavelike disturbance of the tropical easterlies.
It is a kind of wave within the broad easterly current which is generally more slowly than the current in which it is embedded.
Answer:
8 possible combinations
Assuming R 1, R 2 and R 3 be three different Resistance
1- all three in series
2-all three in parallel
3- R 1 and R 2 in series and parallel with R 3
4-R 1 and R 3 in series and parallel with R 2
5-R 2 and R 3 in series and parallel with R 1
6- R 1 and R 2
in parallel and series with R 3
7-R 1 and R 3 in parallel and series with R 2
8-R 2 and R 3 in V with R 1
Mixtures that appear to be the same throughout are homogenous mixtures
Answer:
The change in gravitational potential energy of the climber-Earth system is 
Explanation:
From the question we are told that
The mass of the hiker is 
The time taken is 
The vertical elevation after time T is 
The change in gravitational potential is mathematically represented as

here g is the acceleration due to gravity with value
substituting values
