im not gonna write a research paper but this is the really easy way write global warming talk about animals the polar ice caps and water levels then for what causes it burning fossil fuels and energy plants. then finish off with its awful and we should use solar or geothermic or wind or when the time comes fusion not fission fusion makes helium from hydrogen then burylliam from helium then oxygen and silicon so on so forth instead of fissions uranium,plutonium and thorium and with radioactive waste

A uniform electric field of magnitude 6.8 × 10 5 N/C points in the positive x direction. (a) Find the electric potential differe
Naya [18.7K]

Answer:

i)4080000V

ii)4080000V

iii)5766400v

Explanation:

Hello!

To solve this problem we will use the following steps

1. We will use the equation that defines the distance between two points in order to find the distance from the origin to each of the points that the problem asks for.

d=\sqrt{x^2+y^2}

x= horizonalt component

y=vertical component

d=distance

i)

x=0

y=6

d=\sqrt{0^2+6^2}=6m

ii)

x=6

y=0

d=\sqrt{6^2+0^2}=6m

iii).

x=6

y=6

d=\sqrt{6^2+6^2}=8.48m

2.we calculate the voltage at each point using the equation that relates the distance the voltage and the electric field

V=Ed

where

V=EPD= the electric potential difference

E=electric field  magnitude=6.8 × 10^5 N/C.

d=distance

i)

V=Ed=(6.8 × 105 N/C.)(6)=4080000V

ii)

i)

V=Ed=(6.8 × 105 N/C.)(6)=4080000V

iii)

i)

V=Ed=(6.8 × 105 N/C.)(8.48m)=5766400v

The largest graduated cylinder in my lab holds 2 L and has an inner diamter (the part that holds the water) of 8 cm. When it is
mestny [16]

Answer:

<em>3924 Pa</em>

<em></em>

Explanation:

Volume of cylinder = 2 L = 0.002 m^3  (1000 L = 1 m^3)

diameter of the inner cylinder = 8 cm = 0.08 m  (100 cm = 1 m)

radius of the inner cylinder = diameter/2 = 0.08/2 = 0.04 m

area of the inner cylinder = \pi r^{2}

where \pi = 3.142,

and r = radius = 0.04 m

area of inner cylinder = 3.142 x 0.04^{2} = 0.005 m^2

<em>height h of the water in this cylinder = volume/area</em>

h = 0.002/0.005 = 0.4 m

<em>pressure at the bottom of the cylinder due to the height of water = pgh</em>

where

p = density of water = 1000 kg/m^3

g = acceleration due to gravity = 9.81 m/s^2

h = height of water within this cylinder = 0.4 m

pressure = 1000 x 9.81 x 0.4 = <em>3924 Pa</em>
