Answer:
The wavelength of the light is .
Explanation:
Given that,
Distance between the slit centers d= 1.2 mm
Distance between constructive fringes
Distance between fringe and screen D= 5 m
We need to calculate the wavelength
Using formula of width
Put the value into the formula
Hence, The wavelength of the light is .
Only some metals are attracted by magnets; these metals are called ferromagnetic is your answer
Peer mediation is problem solving by youth with youth. It is a process by which two or more students involved in a dispute meet in a private, safe and confidential setting to work out problems with the assistance of a trained student mediator.
Hooke's Law: F = - k x
Potential energy, PE = [1/2] k x^2 = [1/2] kx x = [kx][x/2] = -Fx/2
F = - 2*PE / x = - 2*0.0030J / 0.0047m = -1.28 N (the negative sigh indicates that the force is opposed to the displacement of the spring)
:
Answer:
741.333
Explanation:
F = ma
so in order to find mass you must change the equation to
m = F/a
m = 5560/7.5
741.333 = 5560/7.5
