Answer:

A The father should sit closer to the pivot.

C The longer wrench makes the job easier because less force is needed when there is more distance from the pivot.

A As far from the head of the hammer as possible because this will maximize torque.

D at the opposite side of the seesaw towards the middle

A beam of monochromatic light (f =5.09 ×1014 Hz) has a wavelength of 589 nanometers in air. What is the wavelength of this light

frosja888 [35]

Lucite has a refractive index of n=1.50. This means that the speed of the light in lucite is decreased according to:
$v=\frac{c}{n}$
where $c=3 \cdot 10^8 m/s$ is the speed of light in air. Putting the number in the formula, we find that the speed of light in lucite is
$v=\frac{3 \cdot 10^8 m/s}{1.50}=2\cdot 10^8 m/s$
The frequency of the light is $f=5.09 \cdot 10^{14}Hz$ , so now we can calculate the wavelength in lucite by using the formula:
$\lambda=\frac{v}{f}=\frac{2\cdot 10^8 m/s}{5.09 \cdot 10^{14} Hz}=3.93 \cdot 10^{-7} m=393 nm$
<span>Therefore, the correct answer is (2) 393 nm.</span>

When a viscous fluid flows in a tube, its velocity is __________.

ankoles [38]

From the equation, r is the distance from the center of the tube. When r = 0, you're considered to be at the centerline and the expression has the highest value. Therefore, the velocity of a viscous fluid is greatest at the center of the tube.
