Three charged particles are positioned in the xy plane: a 50-nC charge at y = 6 m on the y axis, a –80-nC charge at x = –4 m on

leva [86]

Answer:48 V

Explanation:

Given

Three charged particle with charge

$q_1=50\ nC at y=6\ m$

$q_2=-80\ nC at x=-4\ m$

$q_3=70\ nC at y=-6\ m$

Electric Potential is given by

$V=\frac{kQ}{r}$

Distance of $q_1$ from $x=8\ m$

$d_1=\sqrt{6^2+8^2}$

$d_1=\sqrt{36+64}$

$d_1=10\ m$

similarly $d_2=8-(-4)$

$d_2=12\ m$

$d_3=\sqrt{(-6)^2+8^2}$

$d_3=\sqrt{36+64}$

$d_3=10\ m$

Potential at $x=8\ m$ is

$V_{net}=\frac{kq_1}{d_1}+\frac{kq_2}{d_2}+\frac{kq_3}{d_3}$

$V_{net}=k[\frac{q_1}{d_1}+\frac{q_2}{d_2}+\frac{q_3}{d_3}]$

$V_{net}=9\times 10^9[\frac{50}{10}-\frac{80}{12}+\frac{70}{10}]\times 10^{-9}$

$V_{net}=9\times 5.33$

$V_{net}=47.97\approx 48\ V$

A plane flying at 70.0 m/s suddenly stalls. If the acceleration during the stall is 9.8 m/s2 directly downward, the stall lasts

tino4ka555 [31]

Answer:

v = 66.4 m/s

Explanation:

As we know that plane is moving initially at speed of

$v = 70 m/s$

now we have

$v_x = 70 cos25$

$v_x = 63.44 m/s$

$v_y = 70 sin25$

$v_y = 29.6 m/s$

now in Y direction we can use kinematics

$v_y = v_i + at$

$v_y = 29.6 - (9.81 \times 5)$

$v_y = -19.5 m/s$

since there is no acceleration in x direction so here in x direction velocity remains the same

so we will have

$v = \sqrt{v_x^2 + v_y^2}$

$v = \sqrt{63.44^2 + 19.5^2}$

$v = 66.4 m/s$

Bee Movie Script - Dialogue Transcript

According to all known laws

of aviation,

there is no way a bee

should be able to fly.

Its wings are too small to get

its fat little body off the ground.

The bee, of course, flies anyway

because bees don't care

what humans think is impossible.

Yellow, black. Yellow, black.

Ooh, black and yellow!

Let's shake it up a little.

Barry! Breakfast is ready!

Ooming!

Hang on a second.

Hello?

- Barry?

- Adam?

- Oan you believe this is happening?

- I can't. I'll pick you up.

Looking sharp.

Use the stairs. Your father

paid good money for those.

Sorry. I'm excited.

Here's the graduate.

We're very proud of you, son.

A perfect report card, all B's.

Very proud.

Ma! I got a thing going here.

- You got lint on your fuzz.

- Ow! That's me!

- Wave to us! We'll be in row 118,000.

- Bye!

Barry, I told you,

stop flying in the house!

- Hey, Adam.

- Hey, Barry.

- Is that fuzz gel?

- A little. Special day, graduation.

Never thought I'd make it.

Three days grade school,

three days high school.

Those were awkward.

Three days college. I'm glad I took
