Answer:

F = 3.6 x 10⁻²⁴ N

Explanation:

The force of attraction or repulsion between two charges is given by the Coulomb's Law. Coulomb's Law states that:

F = kq₁q₂/r²

where,

F = Electric Force between electrons = ?

k = Coulomb's Constant = 9 x 10⁹ N.m²/C²

q₁ = q₂ = Charge on electron = 1.6 x 10⁻¹⁹ C

r = distance between electrons = 0.8 cm = 0.008 m

Therefore,

F = (9 x 10⁹ N.m²/C²)(1.6 x 10⁻¹⁹ C)(1.6 x 10⁻¹⁹ C)/(0.008 m)²

<u>F = 3.6 x 10⁻²⁴ N</u>

mash [69]

Answer:

the pressure will decrease by 1/2

Explanation:

PV=nRT

P=(nRT)/(V)

nRT are all constant so they will equal 1

V is 2

P=1/2

A ball is thrown straight down with a velocity of 12 m/s; what will be its velocity 2.0 s after being released?
hichkok12 [17]

Answer:

v = 31.6m/s

Explanation:

Given

Initial\ Velocity, u = 12m/s

Time, t = 2.0s

Required

Determine the final velocity, v

Using the first equation of motion

v = u + at

But in this case;

a = g = acceleration of gravity

So:

v = u + gt

Substitute values for u and t

v = 12 + g * 2

v = 12 + 2g

Take g as 9.8m/s²

v = 12 + 2 * 9.8

v = 12 + 19.6

v = 31.6m/s

<em>Hence, the velocity is 31.6m/s</em>

a baker places a paper cone into the center of a fruit pie before putting the pie in the oven. Explain why this would keep juice
zhannawk [14.2K]
<span>Bakers making fruit pies face the problem of the fruit juices running out into the oven and having a soggy crust. An ingenious way of preventing this is to put a paper cone made of thick brown paper in the hole at the center of the top crust as you put the pie in the oven. When the fruit juice boils, it rises into this funnel and then goes back down into the pie, preventing the juice from overflowing all over the crust. Pinching together the upper and lower crusts will prevent the juice from seeping out from the edges.</span>
