The velocity of the wave is defined by the product of wavelength and frequency. The velocity of a wave with a length of 10 m and frequency of 5hz will be 50 m/sec.
<h3>What is the velocity of the wave?</h3>
The velocity of the wave is defined by the product of wavelength and frequency. It is obtained from the formula of the wavelength which is given by;
Hence the velocity of a wave with a length of 10 m and frequency of 5hz will be 50 m/sec.

Answer: Thermal comductivity (K) is 3.964x 10 ^-3 W/m.k
Explanation:
Thermal comductivity K = QL/A∆T
Q= Amount of heat transferred through the material in watts = 75W
L= Distance between two isothermal planes = 0.740mm
A= Area of the surface in square metres = 2m^2
∆T= Temperature change = (37-30) °C.
Solving this : K =( 75 x 0.740 x 10^-3)/ 2 x (37-30)
K = 3.964x 10 ^-3 W/m.k
The net force on the object is zero, so it has no acceleration. It moves in a straight line and at a constant speed (which may be zero).
