Answer:
Multiply the wavelength by the frequency.
Explanation:
The velocity of a wave is the frequency times the wavelength.

ok............I'll try ............
Answer:
Explanation:
Let density of water be ρ .
During flow , volume of water flowing per second is constant
loss of P. E per unit volume = ρ gh , 83.5 % is lost
Gain of K E per unit volume = 1/2 ρ v²
83.5 % of mgh = ρ 1/2 ρ v²
1/2 ρ v² = .835 x 9.8
v² = 2 x .835 x 9.8
= 16.366
v = 4.04 m /s
Answer:
A. quality of road-making material
Explanation:
The CBR method of flexible pavement design gives an idea about the:
A. quality of road-making material
B. traffic intensities
C. characteristics of soil
D. All of the above
The California Bearing Ratio (CBR) test is a penetration test used to evaluate the subgrade strength of roads and pavements. The results of these tests are used with the curves to determine the thickness of pavement and its component layers. it is the measure of the resistance of a material against the penetration of a standard plunger.
This can be used to determine the quality of road making material. CBR is expressed as the percentage of the actual load to the standard load.
