They put gaps between the particles to slow down conduction

They make the material thicker so energy has to travel a further distance.

Answer:The correct answers are:

1. They trap heat in the spaces.

2. They puts gaps between the particles to slow down conduction.

3.The make the material thicker so energy has to travel a further distance.

Explanation:

Insulating materials are those substance which opposes the flow of current through them and makes up bad conductor. There are air spaces present between these substances which :

Traps the heat in the spaces so that movement of energy can be prevented.
These spaces put gap between the particles of substance so that conduction of heat can be prevented.
Makes the material thick so that energy has to travel longer distance so that energy get lost or distributed in an insulator.

All but two gaps within a set of Venetian blinds have been blocked off to create a double-slit system. These gaps are separated

Alecsey [184]

Answer:

Explanation:

separation between two gaps, d = 5 cm

angle between central and second order maxima, θ = 0.52°

use

d Sinθ = n λ

n = 2

0.05 x Sin 0.52° = 2 x λ

λ = 2.27 x 10^-4 m

λ = 226.9 micro metre

The linear momentum of a car of mass 1000 kg moving with a speed of 10 m/s is-----kg.m/s. HELP ME

Assoli18 [71]

Answer:

Explanation:

The kilogram-meter per second (kg · m/s or kg · m · s -1 ) is the standard unit of momentum . Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N · s), which is the SI unit of impulse .
