Answer:

Total energy = 1000J

KE = 500J

PE = 500J

Explanation:

As you may know, the equation for gravitational potential energy is mgh (weight x height)

If the skateboard is halfway down, that means it is at half the height. As the skateboard speeds up (as it goes downward), the potential energy becomes kinetic energy. Since it has 500J of kinetic energy at half way down, it means it had double that amount of Potential energy at the top (1000J). Since half of that became kinetic energy, there is only 500J of PE left.

Total energy = KE + PE = 1000J

KE = 500J

PE = 500J

In a double-slit experiment, the third-order maximum for light of wavelength 490 nm is located 15 mm from the central bright spo
jeka94

Answer:

The distance from the central bright spot are 156.8\times10^{-3}\ mm and 142.9\times10^{-3}\ mm.

Explanation:

Given that,

Wavelength = 490 nm

Distance y= 15 mm

Length L=1.6 m

New wavelength = 670

We need to calculate the distance from the central bright spot

Using formula of distance

y= \dfrac{m\lambda L}{d}

d=\dfrac{m\lambda L}{y}

Put the value into the formula

d=\dfrac{3\times490\times10^{-9}\times1.6}{15\times10^{-3}}

d=156.8\times10^{-6}\ m

d=156.8\times10^{-3}\ mm

We need to calculate the distance from the central bright spot for new wavelength

Using formula of distance

d=\dfrac{m\lambda L}{y}

Put the value into the formula

d=\dfrac{2\times670\times10^{-9}\times1.6}{15\times10^{-3}}

d=142.9\times10^{-6} m

d=142.9\times10^{-3}\ mm

Hence, The distance from the central bright spot are 156.8\times10^{-3}\ mm and 142.9\times10^{-3}\ mm.
