Question 16 (1 point)

Physics
1 answer:
Lerok [7]3 years ago
7 0

Answer:

η = 0.7

Explanation:

The refractive index of the material can be calculated by using the following formula:

\eta = \frac{c}{v}\\

where,

η = refractive index of the material = ?

c = speedof light in vaccuum = 3 x 10⁸ m/s

v = speed of light in this material = 4.3 x 10⁸ m/s

Therefore,

\eta = \frac{3\ x\ 10^8\ m/s}{4.3\ x\ 10^8\ m/s}

<u>η = 0.7</u>

What two things are a included when describing force? Question 3 options: Direction and mass Strength and size Size and directio
Vinvika [58]

Force is a vector quantity and denotes any interaction that change the motion of an object in a certain direction. When influence by force an object can change its velocity or

The two things that are a included when describing force are: magnitude and direction. To fully describe the force acting upon an object, you must describe both the magnitude (size or numerical value) and the direction.

Imagine a universe in which, like in ours, there are two kinds of charges (positive and negative), with the like charges repelli
GuDViN [60]

Answer:

the static charge is not always distributed on the surface of the conductor, there are also charges in the volume but of lesser magnitude

Explanation:

In this hypothetical system the electric force is of type

       F = k' \frac{q_1 q_2 }{r^2}

in this case the force decays to zero much faster,

if we call Fo the force of Coulomb's law

         F₀ = k \frac{q_1 q_2 }{r^2}

assuming the constant k is the same

the relationship between the two forces is

        F / F₀ = 1 / r

        F = F₀ / r

when analyzing this expression the force decays much faster to zero.

In an electric conductor, charges of the same sign may not feel any repulsive force from other charges that are at a medium distance, so there is a probability that some charges are distributed in the volume of the material, this does not happen with coulomb's law

Consequently, the static charge is not always distributed on the surface of the conductor, there are also charges in the volume but of lesser magnitude

A motor spins up the flywheel with a constant torque of 50 n⋅m. how long does it take the flywheel to reach top speed?
dimulka [17.4K]

A motor spins upward the flywheel with a persistent torque of 50N⋅m.

What time does it take the flywheel to get to the top speed?
From the equation: 
Tj = J*dω/dt 


you can get the two equations: 
Δt1= J1*Δω/Tj = 240*125.66/50 = 603.17 sec 
Δt2= J2*Δω/Tj = 120*125.66/50 = 301.58 sec
