satela [25.4K]3 years ago
8 0

Explanation:

initial velocity=0

final velocity=40m/s

time=50s

acceleration=?

now,

a=v-u/t

a=40-0/50

a=40/50

a=0.8m/s^2

A compound wall consists of parallel layers of two different materials, 10 cm of brick and 2 cm of wood. If the difference of te
RSB [31]

The temperature difference between the wooden wall is 16⁰C, and the heat current per square metre of the wall is 7,325 W/m².

<h3>Temperature difference between the wooden wall</h3>

The temperature difference between the wooden wall is calculated as follows;

  • Let the brick wall =  wall A
  • Let the wooden wall = wall B
  • Let the area of the walls = A

\frac{dQ_A}{dt } = \frac{dQ_B}{dt} \\\\\frac{K_A \Delta T_A \times  A}{L_A} = \frac{K_B \Delta T _B \times A}{L_B}\\\\\frac{K_A \Delta T_A }{L_A} = \frac{K_B \Delta T _B}{L_B}\\\\\frac{0.5 \times 20}{0.1} = \frac{0.125 \times \Delta T _B }{0.02} \\\\100 = 6.25\Delta T _B\\\\\Delta T _B = \frac{100}{6.25} \\\\\Delta T _B = 16 \ ^oC

<h3 /><h3>Heat flowing in the walls</h3>

Q = KL(ΔT)

Q = 0.5 x 0.1 x (20 + 273)

Q = 14.65 W

<h3>Heat current per square meter of the Walls</h3>

QA = W/A

QA = (14.65)/A

  • Let the area of the wall = 10 cm x 2 cm = 0.1 m x 0.02 m = 0.002 m².

QA = 14.65/0.002

QA = 7,325 W/m²

What are the different types of precipitation
nikitadnepr [17]

There are many different types of precipitation —rain, snow, hail, and sleet for example—yet they all have a few things in common. They all come from clouds. They are all forms of water that fall from the sky.

What would happen to the railway lines in hot weather if there are no gaps in the track?
Olin [163]
When it gets hot, rails expand.  The gaps in the track allow for it to expand straight, but if there were no gaps, it could expand in unexpected directions, so it could be very dangerous for a train to go over it because they could be bent.

stealth61 [152]

Answer:

The receptors that sense the Earth's magnetic field are probably located in the birds' eyes. Now, researchers at Lund University have studied different proteins in the eyes of zebra finches and discovered that one of them differs from the others: only the Cry4 protein maintains a constant level throughout the day and in different lighting conditions
