The energy travels in a disturbance, in an ocean that disturbance is a wave, so the wave makes energy and moves it through the water

A meter stick is found to balance at the 49.7-cm mark when placed on a fulcrum. When a 41.5-gram mass is attached at the 28.5-cm

zzz [600]

Answer:

The value is $M = 42.3 \ kg$

Explanation:

From the question we are told that

The first position of the fulcrum is x = 49.7 cm

The mass attached is $m = 41.5 \ g$

The position of the attachment is $x_1 = 28.5 \ cm$

The second position of the fulcrum is $x_2 = 39.2 \ cm$

Generally the sum of clockwise torque = sum of anti - clockwise torque

$CWT = m (x_2 - x_1)$

Here CWT stands for clockwise torque

$ACWT = M ( x - x_2)$

$m (x_2 - x_1) = M ( x - x_2)$

=> $41.5 (39.2 - 28.5 ) = M ( 49.7 -39.2 )$

=> $M = 42.3 \ kg$

580 nm light shines on a double slit with d=0.000125 m. What is the angle of the third dark interference minimum(m=3)?

sveta [45]

Answer:

0.796 degree

Explanation:

We are given that

Wavelength= $\lambda=580 nm=580\times 10^{-9} m$

$1nm=10^{-9} m$

$d=0.000125 m$

We have .to find the angle of the third dark interference minimum=3

$sin\theta=\frac{m\lambda}{d}$

Using the formula

$sin\theta=\frac{3\times 580\times 10^{-9}}{0.000125}$

$sin\theta=0.0139$

$\theta=sin^{-1}(0.0139)$

$\theta=0.796^{\circ}$

Hence, the angle of the third dark interference minimum=0.796 degree

An oil tank has a base of area 2.5 m2 and is filled with oil to a depth of 1.2 m. The density of the

asambeis [7]

Answer:

D. F = 24000[N]

Explanation:

To be able to calculate the force we must first find the pressure at the bottom of the tank. By means of the following equation:

$P=Ro*g*h$

where:

Ro = density of the liquid = 800 [kg/m³]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 1.2 [m]

$P=800*9.81*1.2\\P=9417.6[Pa]$

Pressure is defined as the relationship between Force on the area.

$P=F/A\\F=9417.6*2.5\\F = 23544 [N] = 24000[N]$
