Shkiper50 [21]

Answer:

Acceleration =0

Explanation:

There are two forces on the box in horizontal direction.

First one is horizontal component of 30N at 45°.

F=\frac{1}{\sqrt{2} }*30=21.2

Another one is given in opposite to direction of motion mean opposite to this force.

Which is = 2.22 N

Now we know F (net) =mass*acceleration(center of mass)

21.2-21.2 =10*acceleration

acceleration =0

Answer:

Fringe width = 21 mm

Explanation:

Fringe width is given by the formula

\beta = \frac{\Lambda L}{d}

here we know that

\Lambda = 564 nm

L = 4.0 m

d = 0.108 mm

now from above formula we will have

\beta = \frac{(564 \times 10^{-9})(4.0 m)}{0.108\times 10^{-3}}

\beta = 0.021 meter

so fringe width on the wall will be 21 mm

What is the force in N of an object that has a mass of 7 kilograms and acceleration of 6 m/s/s
Marina86 [1]

Newton's 2nd law of motion:         Force = (mass) x (acceleration)

If you want to move a 7-kg object with an acceleration of 6 m/s²,
then you will need to push it with (7 x 6) = 42 newtons of force.

You don't mean the force of an object.
