What is the electric field strength at a distance of .50 m from a 1.00x10^-6 c charge?

ss7ja [257]

Answer:

e = k q / r² then,

e = 9×10^9 * 1×10^-6 / 50² = 3.6 N/C

hope this helps ❤.

a waterwheel built in Hamah, Syria, has a radius of 20 m . If the tangential velocity at the wheels edge is 7.85 m/s , what is t

gtnhenbr [62]

Answer:

3.08m/s²

Explanation:

Given parameters:

Radius = 20m

Tangential velocity = 7.85m/s

Unknown:

Centripetal acceleration = ?

Solution:

Centripetal acceleration is the acceleration of a body along a circular path.

it is mathematically given as;

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

v is the tangential velocity

r is the radius

a = $\frac{7.85^{2} }{20}$ = 3.08m/s²

If a typical smelt weighs 225 g, what is the total mass of pcbs in a smelt in the great lakes? If a typical smelt weighs 225 g,

photoshop1234 [79]

Answer;

= 2.34 x 10^-4 g pcbs

Explanation;

-A typical smelt has 1.04 ppm of PCB is great lakes.

Therefore;

The amount of PCB in a smelt in great leak can be calculated by multiplying the mass of smelt by the pcbs present in a smelt

= 225 g * ( 1.04/100000)

= 2.34 x10^-4 g pcbs
