Question 1 (1 point)

Physics
1 answer:
velikii [3]3 years ago
3 0

Answer:

zirconium

Explanation:

in a liquid, the distance between particles is usually greater than in a solid (with the notable exception of water). Nevertheless, the forces of attraction between particles make liquids, like solids, virtually incompressible. However, the freedom of movement of the particles of liquids is greater than that of the particles of solids.

A hockey puck sliding on smooth ice at 4 m/s comes to a 1-m-high hill. Will it make it to the top of the hill?
solniwko [45]

Answer:

No  it will not make to the top of the hill  

Explanation:

From the question we are told that

   The velocity is  v  =  4 \ m/s

    The height of the hill is  h  = 1 \  m

Generally from the law of energy conservation we have that

   The kinetic energy of the pluck at the level position =  The potential energy of the pluck at the maximum height the  pluck can get  to  

So

       \frac{1}{2}  * m * v^2 =  m *  g *  h_{max}

=>    \frac{1}{2}   * v^2 =    g *  h_{max}

=>     h_{max} =   \frac{0.5 * v^2}{g}

=>     h_{max} =  0.8163 \  m

Given that the maximum height which the pluck can get to at this speed given in the question is less than the height of the hill then conclusion will be that the pluck will not make it to the top of the hill

Complete the passage to describe the relationship between intensity and loudness. Intensity is the amount of ______ that flows i
Usimov [2.4K]

Answer:

Blank One: I'm not certain but I'd assume it's either sound or energy.

Blank Two: Louder

Explanation:

volume is controlled by how much energy is put in an area per a unit of time, so the more energy in one area for a unit of time, the louder the sound will come out.

Sorry I couldn't give the best explanation!

A cylindrical rod of length L is connected across a fixed potential difference, creating a current I through the rod. What would
Inessa05 [86]

Answer:

The value of current through the rod becomes half

i' = \frac{i}{2}

Explanation:

As per Ohm's law we know that the current through a resistor is given as

i = \frac{V}{R}

here we know that

R = \rho \frac{L}{A}

here we know that the length of the cylinder is L and area is A so the value of current through the rod is given as

i = \frac{V A}{\rho L}

now we have change the length of the conductor to twice of initial value and rest all parameters will remain the same

so we will have

i' = \frac{VA}{\rho (2L)}

now from above two equations we have

\frac{i}{i'} = 2

so new current will become

i' = \frac{i}{2}
