Answer:

Temperature stresses are reduced as the multi-cylinder engine has more cooling surface area due to smaller cylinder bore. The intensity of vibration is sufficiently reduced as the primary and secondary forces are balanced. More power strokes per revolution giving smooth torque output.

A client is receiving an IV solution of sodium chloride 0.9% (Normal Saline) 250 ml with amiodarone (Cordarone) 1 gram at 17 ml/

tester [92]

Answer:

1.1mg/min

Explanation:

We are given that

Volume of solution=250 ml

Mass of amiodarone=1 g

Infusion rate=17 ml/hr

We know that

1 g= 1000 mg

Ratio of 1000g:250 ml= $\frac{1000}{25}=4 mg/ml$

The concentration of solution=4mg/ml

Amiodarone infusing (mg/min)= $\frac{infusion \;rate(ml/hr)\times concentration}{60}$

Because 1 hr= 60 minute

Amiodarone infusing=1.1mg/m

Hence, 1.1 mg/min of amiodarone is infusing.

A point charge of -2 µC is located at the origin. A second point charge of 6 µC is at x = 1 m, y = 0.5 m. Find the x and y coord

Soloha48 [4]

Answer:

x coordinate = -1.66 m

y coordinate is = -0.825m

Explanation:

Suppose z be the distance form the first charge and z + sqrt(1^2 +.5^2) be the distance from the second So z + sqrt(1+.25) = z + 1.12

We have k*2.0x10^-6/s^2 = k*6x10^-6/(s+1.12)^2

0.0356s^2 -0.019s-0.0897=0

s=1.876m

The angle of the line between the two charges is arctan(.5/1) = 26.6o

x coordinate = -1.876*cos(26.6) = -1.66m

y coordinate is -1.876*sin(26.6) = -0.825m

When you look at yourself in a convex mirror, you appear to be ¼ your actual size. If you are standing 1.0 m in front of the mir

Nookie1986 [14]

Answer:

The focal length is $f = -0.2 \ m$

The radius of curvature is $R = -0.4 \ m$

Explanation:

From the question we are told that

The magnification of the mirror is $m = \frac{1}{2}$

The distance of the person from the mirror(the object distance ) is $u = - 1.0 \ m$

The negative sign shows that it is been placed in front of the mirror

Generally the magnification of the mirror is mathematically represented as

$m = \frac{v}{u}$

=> $\frac{1}{4} = \frac{v}{-u}$

=> $v = \frac{- 1}{4}$

Generally from the lens equation we have that

$\frac{1}{f} = \frac{1}{u} + \frac{1}{v}$

=> $\frac{1}{f} = \frac{1}{-1 } + \frac{1}{-\frac{1}{4} }$

=> $f = -0.2 \ m$

Generally the radius of curvature is mathematically represented as

$R = 2 * f$

=> $R = 2 * - 0.2$

=> $R = -0.4 \ m$

When you approach a light source that in turn is moving towards you, your speed relative to the emitted light waves _____.?

Natalka [10]

This is a trick question:

The Doppler effect states that as you move closer to the source, the frequency of light(or sound/waves in general) increases, but technically the speed of light is always the same speed, even if you are moving at the speed of light.

Thus, the answer would be something along the lines of <u>don't change</u>.
