Answer: I'd go with Option B if you're allowed to pick One Option Only.

Option A is wrong. Electric Forces arent Non - Conservative. They're Conservative forces.

Option B: We Can Only Define Potential Energies for conservative Forces/fields✅

Option C is wrong. Since the Electric Force is Conservative... It doesn't depend on the path taken.

Option D... There's a Point where the electric Potential Energy is Zero but the separation Distance Would be large.

E is wrong because the Workdone around a closed path is Zero.

If the gradient of an Extension versus Force graph was found to be 5.6, then what is the value of the spring constant? *

worty [1.4K]

Answer:

5.6

Explanation:

F=kx is the formula for spring force. If Extension versus Force was graphed, a linear relation would appear, where the slope is the k value, aka the spring constant.

In a double-slit experiment, the second-order bright fringe is observed at an angle of 0.61°. If the slit separation is 0.11 mm,

tankabanditka [31]

Answer:

$5.86\times 10^{-7}\ \text{m}$

Explanation:

d = Slit separation = 0.11 mm

$\theta$ = Angle = $0.61^{\circ}$

m = Order = 2

$\lambda$ = Wavelength

We have the relation

$d\sin\theta=m\lambda\\\Rightarrow \lambda=\dfrac{d\sin\theta}{m}\\\Rightarrow \lambda=\dfrac{0.11\times 10^{-3}\times \sin0.61^{\circ}}{2}\\\Rightarrow \lambda=5.86\times 10^{-7}\ \text{m}$

The wavelength of the light is $5.86\times 10^{-7}\ \text{m}$ .

Which is more common: a star blows up as a supernova, or a star forms a planetary nebula/white dwarf system?

bazaltina [42]

A planetary nebula is more common to occur than a supernova. It actually is a nebula, meaning mist or cloud but was called planetary nebulae by others because it looked like a planet.

Supernova is a not a usual event to take place.
