Matt forgot to put the fabric softener in the wash. As his socks tumbled in the dryer, they became charged. If a small piece of

lint with a charge of +1.25 E -19 C is attracted to the socks by a force of 3.0 E -9 N, what is the magnitude of the electric field at this location?

Answer:

E = 2.4 \times 10^{10} N/C

Explanation:

As we know that electric field is defined as the force experienced by a unit charge placed in external electric field.

now we know that

q = 1.25 \times 10^{-19} C

F = 3.0 \times 10^{-9} N

now we know that force is related to electric field intensity as per the following relation

F = qE

3 \times 10^{-9} = 1.25 \times 10^{-19} E

E = \frac{3 \times 10^{-9}}{1.25 \times 10^{-19}}

E = 2.4 \times 10^{10} N/C

I can't remember how to solve this kind of problem.
So, in desperation, I take a hard look at the units.

I do remember that electric field is measured in volts per meter,
and 1 volt/meter means 1 newton/coulomb.  And there it is !
The problem has a quantity of [newtons] and a quantity of [coulombs]
in it.  If I divide those, the quotient will be [newton/coulomb], and THAT's
electric field strength !

                 (3.0 x 10⁻⁹ N) / (1.25 x 10⁻¹⁹ C)
 
             =        2.4 x 10¹⁰  N / C

             =        2.4 x 10¹⁰  volts/meter .

Oksanka [162]

Answer:

47 kJoules (kJ)

Explanation:

Potential enegy on Earth is given by the relationship:

P.E. = mgh, where m is mass, g is the acceleration due to Earth's gravity, and h is height. Since we are given metric values, we will look for an answer that is consistent with Joules, the metric measure of energy. 1 Joule is defined as 1 kg*m^2/s^2, so we wnat units of kg, m, and sec.

We are given:

m = 95kg

h = 50 meters

Earth's gravity, g is 9.8 m/s^2

Enter the data:

P.E. = mgh

P.E. = (95kg)(9.8m/s^2)(50m)

P.E. = 46550 kg*m^2/s^2 or 46550 Joules(J)

Since we only have 2 sig figs, and since 1kJ =- 1000J

We can state the potential energy is 47kJ.

Spiderman has 47kJ of potential energy for the start of any dive back to Earth. [He needed that same amount of energy to reach that height, but we don't know from where it came. A jump, helicopter, beamed up by Scotty, or tossed up by Doctor Octopus.]

If the Sun suddenly went dark, we would not know it until its light stopped arriving on Earth. How long would that be, in second
Gre4nikov [31]

Answer: 500 s

Explanation:

Speed v is defined as a relation between the distance d and time t:

v=\frac{d}{t}

Where:

v=3(10)^{8}m/s is the speed of light in vacuum

d=1.5(10)^{11}m is the distance between the Earth and Sun

t is the time it takes to the light to travel the distance d

Isolating t:

t=\frac{d}{v}

t=\frac{1.5(10)^{11}m}{3(10)^{8}m/s}

Finally:

t=500 s
