Match each charged object to the electric field diagram that each would produce?

OK. I see what's going on here.
To answer all of these, you have to know two basic things about the
electric field. 
(THAT's the whole purpose of the question ... to help you determine
whether you're clear on these two things, or need to go over them.)

Thing #1). 
The larger the charge is, the stronger the field is around it,
and a stronger field is indicated with more lines.

Thing #2). 
The direction of the lines is the direction of the force on a tiny positive
charge in the field. 
If the charge in the middle is positive, then another tiny positive charge
gets pushed away from it ... the lines point OUT. 
If the charge in the middle is negative, then a tiny positive charge
gets attracted to it ... the lines point IN.
_________________________

drawing a).
lines point in, charge in the middle is negative
thickest set of lines . . . biggest negative charge

drawing b).
lines point out, charge in the middle is positive
thicker than average lines . . . biggest positive charge

drawing c).
lines point in, charge in the middle is negative
thin lines . . . negative charge in the middle is kind of small

drawing d).
lines point out, charge in the middle is positive
thin lines . . . positive charge in the middle is kind of small
___________________________

I just looked through the charges, to see what they gave us
for positive, negative, big ones, little ones, etc.
BE CAREFUL when you decide which charge to put in the middle.
Don't just look at the beginning numbers ... be sure and consider the exponents too.

According to the Heisenberg uncertainty principle, if the uncertainty in the speed of an electron is 3.5 × 103 m/s, the uncertai
GREYUIT [131]

Explanation:

It is given that,

Uncertainty in the speed of an electron, \Delta v=3.5\times 10^3\ m/s

According to Heisenberg uncertainty principle,

\Delta x.\Delta p=\dfrac{h}{4\pi}

\Delta x is the uncertainty in the position of an electron

Since, \Delta p=m\Delta v

\Delta x=\dfrac{h}{4\pi.m \Delta v}

\Delta x=\dfrac{6.6\times 10^{-34}}{4\pi\times 9.1\times 10^{-31}\times 3.5\times 10^3}

\Delta x=1.64\times 10^{-8}\ m

So, the uncertainty in its position is 1.64\times 10^{-8}\ m. Hence, this is the required solution.

A load of 800 N is lifted using a block and tackle having 5 pulleys. If the applied effort is 200 N, calculate
ser-zykov [4K]

Explanation:

Load=800N

Effort=200N

1. Mechanical Advantage = LOAD/EFFORT

= 800N/200N

= 4

2 Velocity Ratio = no. Of pulleys =5

3. Efficiency = Mechanical advantage / velocity ratio × 100%

= (4/5)×100%

=80%

4. output work= load×load distance

= 800N × 5m

= 4 × 1000J

5. Efficiency = (output work/input work) ×100%

Or, 80% = (4000J/input work) ×100%

Or, 80%/100% = 4000J/inputwork

Or, 4/5 = 4000J/inputwork

Or, input work =4000J × 5/4

Input work = 5×1000J

I hope it helped! ;-)

the weight of 80 kg of mass on mercury is 296 N and almost identical to the weight of the same mass on Mars but mercury has much
Dmitrij [34]
Where Gravity rely's on only mass and distance and nothing else, so the weight on the planets will vary like you have stated. However Mars is smaller than Mercury, so the weight on Mars will be less, and the weight on Mercury will be more. Think this way.

More Mass = More Gravity = More Weight

Less Mass = Less Gravity = Less Weight
