Answer:

n = 3

Explanation:

We know that the nth-order maximum for the Young's two-slit experiment is given by the following expression:

dsin(θ) = nλ

If two maxima concides we must have the relation:

nλ1 = mλ2  --- eq1

In this particular experiment

m = n+1

λ1 = 680 nm

λ2 = 510 nm

Replacing m in eq1 we have

nλ1 = (n+1)λ2

Solving for n we have:

n = λ2/(λ1-λ2)

Therefore:

n = 510/(680-510)=3

A 3.00 cm diameter coin rolls up a 30.0 degree incline plane. The coin starts with an initial angular speed of 60.0 rad/s in a s
yanalaym [24]

Answer:

The coin roll up to 11.57 cm at 30° incline plane.

Explanation:

Given that,

Diameter = 3.00 cm

Angle = 30.0 °

Angular speed = 60.0 rad/s

We need to calculate the length

Using conservation of energy

\dfrac{1}{2}mv^2+\dfrac{1}{2}I\omega^2=mgh

\dfrac{1}{2}mr^2\omega^2+\dfrac{1}{2}\times(0.4mr^2)\times\omega^2=mgl\sin\theta

Put the value into the formula

\dfrac{1}{2}\times(1.5\times10^{-2})^2\times(60.0)^2+\dfrac{1}{2}\times0.4\times(1.5\times10^{-2})^2\times(60.0)^2=9.8\times l\sin30

l\sin30=\dfrac{0.567}{9.8}

l=2\times\dfrac{0.567}{9.8}

l=0.1157\ m

Hence, The coin roll up to 11.57 cm at 30° incline plane.

I need help with science
Nataly [62]

Answer:

Ca = 2

Cl = 2

O = 6

Explanation:

Element given from the question above include = 2CaClO₃

NOTE: The 2 in front of CaClO₃ is affecting Ca, Cl and O.

Thus, the number of each atom of element present in 2CaClO₃ can be obtained as follow:

Ca = 1 × 2 = 2

Cl = 1 × 2 = 2

O = 3 × 2 = 6

Thus,

Ca = 2

Cl = 2

O = 6
