The truck will require force to stop:
Force equals Mass x Acceleration (F = m * a)
Both vehicles will need to decelerate by 55 miles per hour, so the one with a greater mass, m, will require more force to stop. The truck has a mass of 4000 kg, which is greater than the car's
Answer:
Frequency of sound wave in water = 6.8 Hz
Explanation:
Given:
Speed of sound wave in water = 10.2 m/s
The wavelength of the sound wave in water = 1.5 m
Find:
Frequency of sound wave in water
Computation:
Frequency = Speed of wave / Wavelength
Frequency of sound wave in water = Speed of sound wave in water / The wavelength of the sound wave in water
Frequency of sound wave in water = 10.2 / 1.5
Frequency of sound wave in water = 6.8 Hz
Answer:
Explanation:
Circumference in meters is
C = πD = 0.68π
9200 m / 0.68π m = 4,306.545518...
4,306.5 revolutions
Answer:
The correct option is c. 75 for this question
Explanation:
The correct option is c. 75 for this question:
Let's see how.
Continuity Equation is given as:
AcVc = AaVa
Where,
Aa = Area of Aorta
Ac = Area of the capillary
Va = Fluid speed in Aorta
Vc = Fluid speed in Capillary
So,
Assuming the fluid is the ideal one/
/4 
Vc= /4 
Va
Vc= Va
Dc = Da x 
Dc = 2.5 cm x 
Dc = 73.192 cm
Dc = 75 approximately
Hence, the diameter of the capillary = 75 cm approximately
