Answer:
Yes
Explanation:
An increased speed will result in an increased amount of energy, so when it crashes some of that energy will bounce back and crumple the car.
Answer:
Explanation:
Given:
density, 
diameter of the pipe, 
pressure difference, 
In case of pitot tube, the velocity is given by:
Now we know that volumetric flow rate is given as:
where :
a= cross sectional area of the pipe
v= velocity of flow
the determination of the age or date of organic matter from the relative proportions of the carbon isotopes carbon-12 and carbon-14 that it contains. The ratio between them changes as radioactive carbon-14 decays and is not replaced by exchange with the atmosphere.
Work = force in the direction of the movement x distance = 27 N x 1.7 m
Work = 45.9 joules
Answer: option c.
Change in pressure : 772-753 = 19 mm Hg
Since 1 mm Hg = 133 Pa Hg
Then, 19 mm Hg = 2527 Pa Hg
Area of rectangular pool = L* B = 11 x 21 = 231 m^2
To find the force, we multiply the area by the change in pressure: 2527 (231) = 583737N
