Answer:
c. wavelength
Explanation:
The speed of the wave on the string is given by
Here, \mu is the mass per unit length and T is the tension in the string.
For the different thickness, the mass per unit length is different. Therefore, the wave speed is different in the two strings.
The frequency of the oscillations depends upon the oscillator. So, the frequency is same for the two strings by using same oscillator.
The frequency and speed relation is,
f= γλ
λ= f/γ
Since frequency is constant, the wavelength of the waves different as the speeds are different.
Answer:
P.E = 980 Joules
Explanation:
Given the following data;
Mass = 20 kg
Height = 5m
Acceleration due to gravity = 9.8 m/s²
To find the potential energy stored in the block;
Mathematically, potential energy is given by the formula;
Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Substituting into the equation, we have;
P.E = 980 Joules
