A 400g mass object at rest is acted on by a 200 N net force for 12 seconds. What is it’s final velocity?
Kisachek [45]

Explanation:

do we can say that the first step is finding the acceleration of the object. We do so by saying F = ma

so a = F/m

a = 500 m/s^2

we now have the time, acceleration and initial velocity.

so we can find the final velocity by using one of newtons equations which is: vf = vi + at

so:

vf = 0 + 500 × 12

vf = 6000

note that our initial velocity was zero since the object was initially at rest.

if you still have any doubt dont hesitate to ask for further help.

Two point sources are vibrating in phase producing two-dimensional water wave interference. The first antinodal line on either s
Viktor [21]

For all antinodal positions we know that

\Delta \phi = 2N\pi

now we also know the relation between phase difference and path difference

\Delta \phi = \frac{2\pi}{\lambda}\Delta x

now we will have

2N\pi = \frac{2\pi}{\lambda}\Delta x

now from above equation we will have

\Delta x = N\lambda

now for the first anti node position

N = 1

\Delta x = \lambda

Option D is correct
