Answer:
2000 pieces
Explanation:
The number of tiles is given by dividing the area of room by the area of each tile. In this case,
thw areas are as shown below
Area of room is 8*10= 80 m2
Converting dimensions of tiles from cm to m then
Area of tiles is 0.2*0.2= 0.04 m2
No of tiles is 80/0.04=2000 tiles
The geologic force applied to rocks is called compression. Compression<span> is the stress that squeezes </span>rocks<span> together. As a result of the c</span>ompression rocks fold or fracture depending on their compressive strength<span> or </span>compression strength<span> - the capacity of a material or structure to withstand loads tending to reduce size.
</span>When the compression is horizontal the crust will be s<span>hortened and thickened.</span><span> When the compression is vertical maximum a section of rock will fail in </span>normal faults<span>, horizontally extending and vertically thinning a given layer of rock.</span>
(d) option is right answer
HYDROGEN GAS + OXYGEN GAS= HYDROGEN PEROXIDE H2+O2=H2O2 HYDROGEN PEROXIDE IS A LIQUID BECAUSE HYDROGEN PEROXIDE CAN NEVER BE A SOLID BECAUSE TWO LIQUIDS CAN NEVER FORM A GAS IT IS IMPOSSIBLE NO MATTER THE CONDITION
Answer:
27.22 F.
Explanation:
T ( t ) = T₀ + ( T₁ - T₀)
T ( t ) = 41 , T₀ = 0 , T₁ = 140 , t = 15
Put these values in the equation above
41 = ( 140 - 0 ) e^{-15k}
41/140 = e ^{-15k}
(41/140)^{1/3} = e ^{-5k}
Let after 20 minutes temperature becomes T
T = 0 + 140 e^{-k20}
T / 41 = e^{-5k }
= (41/140)^{1/3}
T = 41 X (41/140)^{1/3}
= 27.22 F.
