Wavelength
Question
The total distance between 4 consecutive crests of a transverse wave is 6 m. What is the wavelength of the wave?
Quote the final answer
The wavelength is 2 m.
Answer : <u><em>Gravitational potential energy</em></u>
Explanation :
Gravitational potential is defined as the work done in moving an object from a fixed reference location to the location of object. This arises from the law of gravity and it acts against the gravity.
Mathematically, it is defined as potential energy (U) per unit mass (m).
i.e. 
The general form of Gravitational energy is
where, 
is gravitational constant
and 
are masses of interacting bodies
and 
is the distance between them.
Negative sign shows here that the system is bound.
We know, f = ma
Here, m = 100 kg
a = 20 m/s²
Substitute their values,
f = 100 * 20
f = 2000 N
In short, Your Answer would be 2000 N
Hope this helps!
Answer:
Highest order: m = 1
Explanation:
Formula for solving this is;
dsin θ_m = mλ
We want to find m, thus;
m = (dsin θ_m)/λ
We are told that White light spans from 380nm - 750 nm. Thus, at maximum, λ = 750 nm.
θ_m = 90°
d = (900 lines/mm) = 9000 × 10^(-7) lines/nm
Since we want to find m, the units nm has to cancel out in the equation.
Thus, we will write d in nm/lines as (10^(7))/9000 nm/lines
Thus;
m = ((10^(7))/9000 × sin 90)/750
m = 1.48
Approximately 1
