Answer:
The dimension of thermal conductivity is M1L1T−3Θ−1, expressed in terms of the dimensions mass (M), length (L), time (T), and temperature (Θ). Other units which are closely related to the thermal conductivity are in common use in the construction and textile industries.

Answer:
Scale reading for no wind 
Explanation:
From the question we are told that
Area 
Weight of board 
Velocity 
Density of air 
Generally the equation for pressure difference by Bernoulli equation is mathematically given by


Generally force acting on the board by air is mathematically given by


Therefore
Scale reading for no wind W'


Scale reading for no wind W'=60N
Answer:
Sound and light are similar in that both are forms of energy that travel in waves.
Explanation:
They both have properties of wavelength, freqency and amplitude. ... Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter.
The speed of a wave, c, is given by the length of the wave, λ, times the frequency (times per second a cycle passes). Since frequency has units of inverse seconds, the units will then be m/s as we expect.
0.3 is your answer, good luck!!!!
