Velocity of a wave is the amount of wavelength multiplied by its frequency. Moreover, derivations would be;wavelength?
Hence wavelength would be velocity divided by the frequency.Result is 2.1 mThank you for your question. Please don't hesitate to ask in Brainly your queries.
Answer:
Explanation:
The energy stored in a spring
= 1/2 k x²
where k is spring constant and x is extension in the spring.
= .5 x 500 x .05²
= .625 J
Work done by friction = energy dissipated
= - μmg x d , μ is coefficient of friction , m is mass , d is displacement
= - .35 x 2.8 x 9.8 x .05
= - .48 J
energy of the mass when it reaches equilibrium position
= .625 - .48
= .145 J
If v be its velocity at that time
1/2 m v ² = .145
.5 x 2.8 x v² = .145
v² = .10357
v = .32 m /s
32 cm /s
I need help on that one 2 someone please help
He still move deforce stopping this call law of inertia depend on the mass of object
Double
Explanation:
Since the period T of a pendulum is given by
By increasing the length of the pendulum by 4, the period becomes
You can see that the period doubles when we increase the length by a factor of 4.
