Answer:

Speration between the slits d=2.86\ \mu m

Explanation:

Given that,

Wavelength of light, \lambda=612\ nm=612\times 10^{-9}\ m

It is incident on a double slit produces a second-order maximum at an angle of 25 degree.

The condition for maxima is given as :

dsin\theta=m\lambda

d = seperation between the slits

m = order, m = 2

d=\dfrac{m\lambda}{sin\theta}

d=\dfrac{2\times 612\times 10^{-9}\ m}{sin(25)}

d = 0.00000289

or

d=2.86\mu m

So, the seperation between the silts is 2.86\ \mu m. Hence, this is the required solution.

Answer:

See the answers below.

Explanation:

We can solve both problems using Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

∑F =m*a

where:

F = force [N] (units of newtons)

m = mass = 1000 [kg]

a = acceleration = 3 [m/s²]

F = 1000*3\\F=3000[N]

And the weight of any body can be calculated by means of the mass product by gravitational acceleration.

W=m*g\\W=1000*9.81\\W=9810 [N]

seropon [69]

Answer: Option B. R = (1/2)gt^2

Explanation:

S = R (horizontal distance)

V^2 = 2gS

V^2 = 2gR

R = V^2 / 2g

But V = gt

R = (gt)^2 / 2g

R = (g^2 x t^2) / 2g

R = gt^2 / 2

But t^2 = 2h/g

R = ( g x 2h/g) / 2

R = h

But h = (1/2)gt^2

R = h = (1/2)gt^2
