Answer:

False

Explanation:

The formula of force that exists between two charges is expressed as;

F = kq1q2/r²

If two charges separated by one meter exert a 9 N force on each other, the;

9 = kq1q2/1²

9 = kq1q2 ..... 1

If the charges are pushed to a 3 meter separation, then;

F =  kq1q2/3²

F =  kq1q2/9 .... 2

Divide both equations;

9/F = (kq1q2)/ kq1q2/9

9/F =  kq1q2 * 9/ kq1q2

9/F = 9

F = 9/9

F = 1N

Hence if the charges are pushed to a 3 meter separation, then the force on EACH charge will be 1N. Hence the answer is False

First, let's list everything we have...

a = 1.83 m/s^2

F = 1870 N (converted from kN to N)

vi = 0 m/s (it says started from rest, therefore velocity starts at 0)

t = 16 s

1). "Force acting on the car" is a bit ambiguous because there are many forces. But I'm going to assume that they are looking for just a basic implementation of force equation:

F=ma

where:

F = force

m = mass

a = acceleration

2). I recommend memorizing your equations of motion, because once you know them this part is also just as easy:

v_f=v_i+at

where:

vf = final velocity

vi = initial velocity

a = acceleration

t = time

Density = (mass) / (volume)

Density = (20 g) / (5 cm³)

<em>Density = 4 g/cm³</em> .

The density of the substance is greater than the density of water. A lump of the substance <em>will sink in water</em>, <u>unless</u> the lump is formed into a shape that displaces 20 cm³ of water or more, such as a tiny boat shape.

Pls guys what is displacement​
KengaRu [80]

Answer:

Displacement is the shortest distance from your initial position to your final position. Therefore, displacement is a measurement of distance and not an "end-point."
