Answer:

17.27 Hz

Explanation:

Applying

v = λf................ Equation 1

Where v = speed of the car, λ = Distance between successive crevice, f = number of crevice moved in 1 seconds(Frequency of the vibration)

make f the subject of the equation

f = v/λ............. Equation 2

From the question,

Given: v = 38 m/s, λ = 2.2 m

Substitute these values into equation 2

f = 38/2.2

f = 17.27 Hz

Why the blood pressure in human body is greater at the feet than at the brain. please help!!!!​
maxonik [38]

Answer:

The pressure of liquid column is given by p=hpg, where h is depth, p is density and g is acceleration due to gravity.

Therefore, pressure of the liquid column increases with depth. The height of the blood column in a human body is more at feet than at the brain. Therefore, the blood pressure in humans is greater at the feet than the brain.

Kamila [148]

Answer:

0.1667 m/s

Explanation:

m1V1 + m2V2 = m1V3 + m2V4

0.01 = ( 0.0075) + (0.015 * V4)

V4 = (0.01 - 0.0075) / (0.015)

V4= 0.1667
