Why do your feet feel colder stepping on ceramic tiles than on carpet?

Physics
2 answers:
gregori [183]3 years ago

Answer:

Option B

Tile is a good conductor : a carpet is a good insulator

Explanation:

When the feet comes in contact with the tile, the tile conducts heat from the body making one to feel cold. However, since carpet is made of insulators such as cotton, they don't conduct heat, therefore, it slows down the flow of the heat which would make it feel warm so our feet do not feel much more colder as it does with the tiles.

Answer:

B) Tile is a good conductor : a carpet is a good insulator

Explanation:

Heat travels from hot to cold. Your feet are warmer than the tile. The tile is a conductor and when you step on it, heat from your body transfers to the tile making it feel cool.

Kelly Clarkson is running between the Patronas towers in Kuala Lumpur on a tightrope at a speed of 15 m/s. Kelly currently weigh
Tomtit [17]

KE = 8887.5 J

<h3>Further explanation</h3>

Given

speed = 15 m/s

weight = 79 kg

Required

KE-Kinetic energy

Solution

Energy is the ability to do work  

Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:  

\large {\boxed {\bold {KE = \frac {1} {2} mv ^ 2}}}

Input the value :

KE = 1/2 x 79 kg x 15² m/s²

KE = 8887.5 J

uniform electric field of magnitude 365 N/C pointing in the positive x-direction acts on an electron, which is initially at rest
vfiekz [6]

Answer:

a)   W = - 1.752 10⁻¹⁸ J,  b)    U = + 1.752 10⁻¹⁸ J

Explanation:

a) work is defined by

         W = F . x

the bold letters indicate vectors, in this case the force is electric

         F = q E

we substitute

         F = q E x

the charge of the electron is

         q = - e

         F = - e E x

let's calculate

         W = - 1.6 10⁻¹⁹  365  3 10⁻²

         W = - 1.752 10⁻¹⁸ J

b) the change in potential energy is

          U = q ΔV

the potential difference is

          ΔV = - E. Δs

 

we substitute

         U = - q E Δs

the charge of the electron is

           q = - e

          U = e E Δs

we calculate

           U = 1.6 10⁻¹⁹ 365  3 10⁻²

           U = + 1.752 10⁻¹⁸ J

The length of a wooden rod is 25.5 cm. What is this length in:<br>(a) millimetres?<br>(b) metres?​
larisa86 [58]

Answer:

(a)255mm \\ (b)0.255m

Explanation:

(a)1cm = 10mm \\ 25.5cm = x

Cross multiply

1x = 25.5 \times 10 \\ x = 255mm

(b)100cm = 1m \\ 25.5cm = x

cross multiply

100x = 25.5 \\  \frac{100x}{100}  =  \frac{25.5}{100}  \\ x = 0.255m

hope this helps

brainliest appreciated

good luck! have a nice day!
