Two charged plates separated by 15 cm create a uniform electric field of 360 n/c. what is the potential difference between the p
nikitadnepr [17]

When two charged plates are separated by a distance, the potential difference between the plates is 54 Volts.

<h3>What is uniform electric field?</h3>

The electric field intensity which does not increase or decrease with time or remain constant is called the uniform electric field.

Given is the plates separated by distance d = 15 cm =0.15 m, electric field E= 360 N/C.

The relation between the electric field and voltage is

E=V/d

Substitute the values into the expression to get the potential difference V,

V = 360 x 0.15

V = 54 Volts

Thus, the potential difference between the plates is 54 Volts.

Compare the advantages and disadvantages of buying compact fluorescent bulbs rather than filament bulbs (6 marks)
myrzilka [38]
Advantages
-Fluorescent bulbs are more efficient than filament bulbs
-They are cheaper to use as they consume less electricity
-Lasts longer
-Since it consumes less electricity, less electricity needs to be produced, so less fossil fuels needs to be burnt so less harm to the environment.
Disadvantages
-More expensive to buy
-Shortened life span if turned off and on very frequently.
-Disposal a problem because of mercury vapour.

I hope this helps!

According to the Guinness Book of World Records (1990 edition, p. 169), the highest rotary speed ever attained was 2010 m/s (450
Valentin [98]

When a body performs a uniform circular motion, the direction of the velocity vector changes at every moment. This variation is experienced by the linear vector, due to a force called centripetal, directed towards the center of the circle that gives rise to centripetal acceleration, the mathematical expression is given as,

a = \frac{v^2}{r}

Where,

v =  Tangential Velocity

r = Radius

The linear velocity was 2010m/s in a radius of 0.159m, then the centripetal acceleration is

a = \frac{2010^2}{0.159}

a = 2.54*10^7m/s^2

Therefore the centripetal acceleration of the end of the rod is 2.54*10^7m/s^2
