Answer:

An insulator opposes the flow of electricity. Insulators are important to keep us safe from electricity. The wire that carries electricity to your computer or television is covered with a rubber-like insulator that protects you from getting electrocuted. Good insulators include glass, the air, and paper.

Answer:

θ=142.9°

Explanation:

d=1 *r

angle ϕ= 37.1°

the line connecting pebble and target should be tangent to a circle so

cos(180-ϕ-θ)= $\frac{r}{d}$ = $\frac{1}{1}$

∴ θ=180-ϕ- $cos^{-1} (\frac{1}{1} )$

θ= 180-37.1-0

θ=142.9°

Two 2.0cm×2.0cm metal electrodes are spaced 1.0 mm apart and connected by wires to the terminals of a 9.0 v battery. What is the

Fantom [35]

Answer:

The charge on each electrode is

$q=0.354 x10^{-12}$

Explanation:

The charge to find the equation is development

V=9v

$d=1.0 mm\\A=2cm*2cm=0.02m*0.02m\\A=4x10^{-4} \\E_{o} =8.85x10^{-12} (\frac{C^{2} }{N*m^{2} } )$

$q=C*V$

$C=\frac{E_{o}*A }{d} \\C=\frac{8.85x10^{-12} *4x10^{-4} }{0.01}=0.354 \\$

$q=0.354*9v\\q=3.186x10^{-12} C$

It takes 25N or force to drag a box along the floor at a constant speed. If the coefficient of friction is .3, what is the mass

Nataliya [291]

The mass of the box is 8.5 kg.

<h3>What is mass?</h3>

Mass can be defined as the quantity of matter contained in a body.

To calculate the mass of the box, we use the formula

Formula:

F = mgμ............. Equation 1

Where:

F = Force
m = mass of the box
g = acceleration due to gravity
μ = coefficient of friction

Make m the subject of the equation

m = F/gμ..................... Equation 2

From the question,

Given:

F = 25 N
g = 9.8 m/s²
μ = 0.3

Substitute these values into equation 2

m = 25/(0.3×9.8)
m = 25/2.94
m = 8.5 kg

Hence, the mass of the box is 8.5 kg.
