A parallel-plate capacitor is connected to a battery. The space between the two plates is empty. If the separation between the c

Answer:

The final stored energy will become half.

Explanation:

We know that stored energy in the capacitor is given as

$E=\dfrac{1}{2}CV^2$

C=capacitance

V=Voltage difference

E=Energy

$C=\dfrac{\varepsilon A}{d}$

d=Distance between plates

A=Area

$E=\dfrac{1}{2}\times \dfrac{\varepsilon A}{d}\times V^2$

If the distance between plates get double ,say d' = 2 d

Then stored energy

$E'=\dfrac{1}{2}\times \dfrac{\varepsilon A}{d'}\times V^2$

$E'=\dfrac{1}{2}\times \dfrac{\varepsilon A}{2d}\times V^2$

$E'=\dfrac {E}{2}$

Therefore the final stored energy will become half.

Explain two reasons why sea ice so important to a polar bear.

Zolol [24]

This loss of stable old ice has set up additional losses of sea ice cover each summer because the thinner younger ice is more easily melted during the recent warmer summers. Because of their dependence upon the sea ice for food, these changes can directly affect the carrying capacity of the Arctic for polar bears. Mark this as the brainliest answer please

A couch of mass 210 kg is being pushed across the floor with an applied force of 4100 N. The coefficient of kinetic friction bet

Dennis_Churaev [7]

Let us use the formula for Newton's Second Law of Motion:

Net force = Mass*Acceleration
Net force = Applied Force - μ*Normal Force
where μ is the coefficient of kinetic friction

Normal Force = Force due to gravity = mass*gravity
Normal Force = (210 kg)(9.81 m/s²) =<em> 2,060.1 N</em>

Then,
Net force = 4100 - 0.38*2060.1 = 3317.162 N

3317.162 N = (210 kg)(a)
Solving for acceleration,
<em>a = 15.796 m/s²</em>
