There is no air pressure on the moon, so the liquids will shoot straight up, possibly causing you to choke.

Two infinite nonconducting sheets of charge are parallel to each other, with sheet A in the x = -2.15 plane and sheet B in the x

GalinKa [24]

Answer:

a) (-367231.63i , 367231.63i, 0) N/C

b) (0 , 0 , 367231.63i ) N/C

Explanation:

Case x < -2.15

$E =E_{+} + E_{+} \\E = 2*\frac{sigma}{2e_{0} } = \frac{sigma}{e_{0} }\\\\E = \frac{3.25*10^(-6)}{8.85*10^(-12) }\\\\E = - 367231.63 i$

Case x > 2.15

$E =E_{+} + E_{+} \\E = 2*\frac{sigma}{2e_{0} } = \frac{sigma}{e_{0} }\\\\E = \frac{3.25*10^(-6)}{8.85*10^(-12) }\\\\E = +367231.63 i$

Case -2.15 < x <+2.15

$E =E_{+} - E_{+} \\\\E = 0$

Case x < -2.15

$E =E_{+} - E_{+} \\\\E = 0$

Case x > 2.15

$E =E_{+} - E_{+} \\\\E = 0$

Case -2.15 < x <+2.15

$E =E_{+} + E_{-} \\E = 2*\frac{sigma}{2e_{0} } = \frac{sigma}{e_{0} }\\\\E = \frac{3.25*10^(-6)}{8.85*10^(-12) }\\\\E = +367231.63 i$

Brums [2.3K]

Answer:

Seven.

Explanation:

A period is a horizontal row of the periodic table. There are seven periods in the periodic table, with each one beginning at the far left. A new period begins when a new principal energy level begins filling with electrons.

1. A 1000 kg bag of sand has an<br> acceleration of 0.5m/s/s. What is the<br> force on the bag?

densk [106]

Answer:

We conclude that the force on the bag is 500 N.

Explanation:

Given

Mass m = 1000 kg

Acceleration a = 0.5 m/s²

To determine

Force F = ?

We know that when a force is applied to a body, it produces acceleration.

<u>Important Tip: </u>

We can determine the force on the bag using the formula F = ma

Using the formula

$F = ma$

where

$F$ is the force

$m$ is the mass

$a$ is the acceleration

now substitute m = 1000, and a = 0.5 m/s² in the formula

$F = ma$

$F = (1000)(0.5)$

$F=500$ N

Therefore, we conclude that the force on the bag is 500 N.
