Which single force acts on an object in free fall

Physics
2 answers:
Pavel [41]3 years ago
5 0

Answer:

Gravitational force

Explanation:

An object moving under free fall, the force acting on it is only gravity. The object move under the action of gravitational force. The force of gravity is always attractive. This force depends on the masses and the distance between masses.

Hence, force of gravity is the only force acting on the object when it is moving in free fall.

Now consider a wave which is paired with seven other waves into seven pairs. The two waves in each pairing are identical, except
Nikitich [7]

Answer:

<em>BCEG,ADF</em>

Explanation:

Between 2 waves, if path difference is mλ, m is an integer and they interfere constructively.

Between 2 waves, if path difference is (m+1/2)λ, m is an integer and they interfere destructively.

Light of wavelength O is passed through a diffraction grating with N lines/meter and then lands on a screen a distance L from th
rodikova [14]

Condition for diffraction

dsin\theta = m\lambda

Where

a = Distance between slits

m = Order of the fringes

\lambda = Wavelength

\theta = At the angle between the ray of light and the projected distance perpendicular between the two objects

For small angles

sin\theta = \approx tan\theta

Where

tan\theta = \frac{Y}{L}

Where L is the distance between the slits and Y the length of the light.

Replacing we have

d\frac{Y}{L} = \lambda m

Y = \frac{m\lambda L}{d}

The distance between slits d can be expressed also as d= \frac{L}{N} Where N is the number of the fringes, then

Y_n = mN\lambda L

Similarly when there is added a new Fringe we have the change of the distance would be :

Y_{n+1} = (m+1)N\lambda L

Linear distance between fringes is

\Delta Y = \Delta Y_{m+1}-Y_m

\Delta Y = (m+1)N\lambda L - mN\lambda L

Therefore the answer is

\Delta Y = N\lambda L
