Explanation:
electricity is the flow of electrical power or charge
Answer:
K = .3941 × 10³ W/m.K
Explanation:
Qcond = K A ΔT÷ L
∴K = Qcond ×L ÷ A ΔT
J ÷ S = P
P = I × V =Qcond
∴Qcond = I × V
= 0.6 A × 110 V
=66 W
L = 0.12 m
ΔT = 8 °C
Qcond =33 V
Area = (πD²) ÷ 4
= [π (4 × 10⁻² )²] ÷ 4
= 1.256 × 10⁻³ m²
∴A = 1.256 × 10 ⁻³³ m²
So K = ( Qcond × L ) ÷ A ΔT
= (33) (0.12 ) ÷ (1.256 ×10⁻³ ) × 8
= 0.3941 × 10³ W/m .K
1 centimetres = 10 millimetres
178 centimetres = 10 × 178 = 1780 millimetres
First and second options are incorrect
------------------------------------------------------------------------------------------------------
1 metres = 100 centimetres
178 centimetres = 178 ÷ 100 = 1.78 metres
Third option is correct
-----------------------------------------------------------------------------------------------------
1 cm = 10 mm
1 mm = 1000 micrometres
1 cm = 10000 micrometres
178 cm = 178 × 10⁴ micrometres
Fourth option is incorrect
-----------------------------------------------------------------------------------------------------
1 kilometre = 1000 metres
1 metre = 100 cm178 cm = 178 ÷ 100 = 1.78 metres
1.78 metres = 1.78÷1000 = 1.78 × 10⁻³ kilometres

Correct answer: third option
You could cook it and then drop it or you can always wrap it in bubble wrap.
Igneous rocks are rocks that form through the cooling and solidification of magma or lava.
