The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh, where s is the atmospheric pressure, d is the density of the liquid, and gas the acceleration due to gravity.

p = s + dgh

dgh = p - s

h = (p - s)/dg

Which formula represents h in terms of p, s, d, and g? Formula B is correct.

Calculate the stroke of a slider-crank where the crank radius is 4.13 inches and the coupler is 5 inches.

scoray [572]

Answer:

$x=8.268 inches$

Step-by-step explanation:

From the question we are told that:

Radius $r=4.13$

Coupler $C= 5 inches.$

Generally the equation for Stroke in a slider-crank Mechanism x is mathematically given by

$x=2* Radius$

$x=2*4.13$

$x=8.268 inches$

If the diameter of circle C is 3 times greater than the diameter of circle D, the area of circle C is how many times the area of

amid [387]

The radius of circle C is also 3 times greater than the radius of circle D.
The area of circle C:
A C = (3r)² π = 9 r² π
The area of circle D:
A D = r² π
9 r² π : r ² π = 9
Answer: It is 9 times the area of circle D.

A line has a slope of 1/4 and passes through point (0.4,-1/2). What is the value of the y-intercept?

AVprozaik [17]

Answer: The value of the y-intercept is $-\frac{3}{5}$

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

In this case we know that the line passes through point $(0.4,-\frac{1}{2})$ and has a slope of $\frac{1}{4}$ . Then we can substitute the following values into $y=mx+b$ :

$x=0.4\\\\y=-\frac{1}{2}\\\\m=\frac{1}{4}$

Then:

$-\frac{1}{2}=\frac{1}{4}(0.4)+b$

And finally, we must solve for "b":

$-\frac{1}{2}=\frac{1}{4}(0.4)+b\\\\-\frac{1}{2}-\frac{1}{10}=b\\\\b=-\frac{3}{5}$
