Answer:

Distance between slits, d=2.89\times 10^{-7}\ m  

Explanation:

It is given that,

Wavelength, \lambda=410\ nm=410\times 10^{-9}\ m

Angle, \theta=45

We need to find the distance between two slits that produces first minimum. The equation for the destructive interference is given by :

d\ sin\theta=(n+\dfrac{1}{2})\lambda

For first minimum, n = 0

So, d\ sin\theta=(\dfrac{1}{2})\lambda

d is the distance between slits

So, d=\dfrac{1/2\lambda}{sin\theta}

d=\dfrac{1/2\times 410\times 10^{-9}}{sin(45)}

d=2.89\times 10^{-7}\ m

So, the distance between two slits is 2.89\times 10^{-7}\ m. Hence, this is the required solution.

A toy of mass 0.155 kg is undergoing simple harmonic motion (SHM) on the end of a horizontal spring with force constant 305 N/m
zzz [600]

Answer:

310.38\times 10^{-4}j

Explanation:

We have given mass m=0.155 kg

Force constant K = 305 N/m

Distance X=1.25\times 10^{-2}m

Velocity v=.305 m/sec

The total energy at any position of the motion is give by E=\frac{1}{2}mv^2+KX^2  here \frac{1}{2}mv^2 is energy due to motion and KX^2  is energy due to spring elongation

So total energy E=\frac{1}{2}\times 0.155\times 0.305^2+305\times 0.0125^2=310.38\times 10^{-4}j

meriva

Answer:

m = 17.87 kg

Explanation:

As we know that tank itself has mass given as 13.4 kg

so it is given as

m_1 = 13.4 kg

also the tank contains air in it and the mass of air inside the tank is also given as 4.47 kg

so it is

m_2 = 4.47 kg

so total mass of the tank is the mass of the empty tank and mass of air in the tank

m = m_1 + m_2

m = 13.4 + 4.47

m = 17.87 kg
