Energy of wave depends on its amplitude and it is given as
here k = constant
A = amplitude
so energy will increase or decrease depends on the amplitude of the wave
So here if we need to check which wave has lower energy then we need to compare the amplitude.
If the amplitude is less then energy must be less
So please check in the figure that which wave out of A and B has lesser amplitude to find out the wave of lesser energy
Answer:
32.52 N
Explanation:
F-F' = ma.................. Equation 1
Where F = Force needed to pull the block, m = mass of the block, a = acceleration of the block, F' = Frictional force of the surface acting on the blcok
F = ma+F'
But,
F' = μmg
Where g = acceleration due to gravity, μ = coefficient of static friction
F = ma+μmg.................... Equation 2
Given: m = 6.0 kg, a = 1.5 m/s², μ = 0.40
Constant: g = 9.8 m/s²
Substitute these values into equation 2
F = 6(1.5)+6(9.8)(0.4)
F = 9+23.52
F = 32.52 N
Answer:
resultant force = 59 N
Explanation:
we know the formula: <em>Force = mass * acceleration</em>
Force = 25 kg * 2.36 m/s²
Force = 59 N
False
we can calculate it at a specific time by taking the derivative of positive function, which gives us the functional form of instantaneous velocity v(t)
No. You can look up the wavelengths of the electromagnetic spectrum and you will see that they cover a very large range of wavelengths.
