The answer would be vertically. This is from the time when there is already an incomplete polarization in the direction of the analogous to the horizontal surface, we only need to relate some vertical polarization (through sunglasses) to stabilize things off.

Lena [83]

Answer: 316.8V

Explanation:

given data:

metre moving current = 0.96mA

meters voltage = 288V

or  0.96*300V = 288V

<u><em>Solution:</em></u>

<u><em /></u>v1 = (0.96mA*150)<u><em /></u>

<u><em /></u>= 144V<u><em /></u>

<u><em /></u>

i1 = \frac{144v}{750}

= 0.192mA

i2 = imovement + i1

i2= 0.96mA+0.192mA

= 1.152mA

Vmeasured = 144V+(150)(1.152mA)

=316.8V

the unknown voltage is 316.8V

A proton is released in a uniform electric field, and it experiences an electric force of 5 X 10^-10 N toward the South. What is
Ymorist [56]

Answer:

Electric field on proton

E=3.12\times 10^9\ N/C

Explanation:

Given that

Force,F=5\times 10^{-10}\ N

We know that

Charge on proton

q=1.6\times 10^{-19}\ C

We know that

Force = Electric field x Charge

F= E x q

E=\dfrac{F}{q}\ N/C

E=\dfrac{5\times 10^{-10}}{1.6\times 10^{-19}}\ N/C

E=3.12\times 10^9\ N/C

Electric field on proton

E=3.12\times 10^9\ N/C

What does basketballs have inside of it
FrozenT [24]
Hi there!

Great question!

Basketballs have air inside them. A special pump is used to insert the air. That's why you can lift the basketballs off the ground easily. If it was a solid, though, you'd hardly be able to lift the ball up! Basketballs can float, too, because anything with air inside can float. If it were solid, it would sink in the water easily.

Hope this helps! :D

The graph below shows the velocity of a car over time.
jekas [21]

Answer:

D. Calculate the area under the graph.

Explanation:

The distance made during a particular period of time is calculated as (distance in m) = (velocity in m/s) * (time in s)

You can think of such a calculation as determining the area of a rectangle whose sides are velocity and time period. If you make the time period very very small, the rectangle will become a narrow "bar" - a bar with height determined by the average velocity during that corresponding short period of time. The area is, again, the distance made during that time. Now, you can cover the entire area under the curve using such narrow bars. Their areas adds up, approximately, to the total distance made over the entire span of motion. From this you can already see why the answer D is the correct one.

Going even further, one can make the rectangular bars arbitrarily narrow and cover the area under the curve with more and more of these. In fact, in the limit, this is something called a Riemann sum and leads to the definition of the Riemann integral. Using calculus, the area under a curve (hence the distance in this case) can be calculated precisely, under certain existence criteria.
