V = \frac{m}{\rho}
V = \frac{3.2}{16.8}
V = 0.19 mL

We know that d=m/v where d is density, m is mass and v is volume. Lets transform formula to get v in times of d and m
d= \frac{m}{V}  /*V \\ V*d=m /:d \\ V= \frac{m}{d}
Now we have to substitute our data to formula
V=\frac{3.2}{16.8}=0.19 ml - its the answeer

A loudspeaker, mounted on a tall pole, is engineered to emit 75% of its sound energy into the forward hemisphere, 25% toward the
Naily [24]

Answer:

"0.049 W" is the correct answer.

Explanation:

According to the given question,

r = \sqrt{(3.5)^2+(2.5)^2}

  =\sqrt{8.5}

SL=85

As we know,

⇒  SL=10 \ log(\frac{I}{I_o} )

     85=10 \ log(\frac{I}{10^{-12}} )

      I=3.162\times 1^{-4} \ W/m^2

Now,

⇒  P_{front} = I(2\pi r^2)

               =(3.162\times 10^{-4})(2\pi\times 18.5)

               =0.0368 \ W

               =0.75 \ P

or,

                =0.049 \ W

Figure A shows cross section of a land form or rock. In Figure B, compression stress is applied on it. When compression stresses are applied on a rock, it squeezes the rock cause fold or fracture. The fault formed by compression stress is called thrust fault. If the compression stresses/ force continue to act on a rock it will converge and form thrust fault. In Figure C, tension stresses is applied on the rock. When a tension stress applied on a rock it deforms/ lengthen. There are three type of deformations occur due to tension stresses. One is elastic deformation, in which, rock retains it original shape when force/stresses are removed. Second is plastic deformation, in which rock lengthen and change occur permanently. Third type of deformation is result into fracture or breaking of rock. In Figure C, shear stresses are applied on rock. Shear stresses are applied with equal magnitude but in opposite direction. It cause breaking of rock.

What must be the distance (in meters) between a point charge q1 = 16 μC and a point charge q2 = 32 μC for the electrostatic forc
adoni [48]

Answer:

d = 0.71 meters

Explanation:

It is given that,

Charge 1, q_1=16\ \mu C=16\times 10^{-6}\ C

Charge 2, q_2=32\ \mu C=32\times 10^{-6}\ C

Electrostatic force between charges, F = 9 N

Let d is the distance between the charges. The electrostatic force between the charges is given by the product of charges and divided by square of distance between them. Mathematically, it is given by :

F=k\dfrac{q_1q_2}{d^2}

d=\sqrt{\dfrac{kq_1q_2}{F}}

d=\sqrt{\dfrac{9\times 10^9\times 16\times 10^{-6}\times 32\times 10^{-6}}{9}}

d = 0.71 meters

So, the distance between the charges is 0.71 meters. Hence, this is the required solution.
