When we first dig into soil, it's nice and soft.( Depending on what soil it is; usually topsoil)

But when we go deeper into it, there are rocks and the soil is harder. There is bedrock at the bottom, subsoil in the middle, and topsoil at the top, which is where we walk.

The molecule of magnet are independent _____________

Bas_tet [7]

Answer:

The first is the electric field, which describes the force acting on a stationary charge and gives the component of the force that is independent of motion. The magnetic field, in contrast, describes the component of the force that is proportional to both the speed and direction of charged particles.

A long, thin straight wire with linear charge density λ runs down the center of a thin, hollow metal cylinder of radius R. The c

Delvig [45]

Answer:

$E=\dfrac{\lambda }{2\pi \varepsilon _or}$

Explanation:

Given that

For straight wire

Charge density= λ

For hollow metal cylinder

Charge density=2 λ

We know that electric filed for wire given as

$E_w=\dfrac{\lambda_{wire} }{2\pi \varepsilon _or}$

$E_w=\dfrac{\lambda }{2\pi \varepsilon _or}$

Now the electric filed due to hollow metal cylinder

$E_c=\dfrac{\lambda_{cylinder} }{2\pi \varepsilon _or}$

$E_c=\dfrac{2\lambda }{2\pi \varepsilon _or}$

Now by considering the Gaussian surface r<R then only electric fild due to wire will present.So

At r<R

$E=\dfrac{\lambda }{2\pi \varepsilon _or}$

A speedy tortoise can run with a speed of <img src="https://tex.z-dn.net/?f=v_T" id="TexFormula1" title="v_T" alt="v_T" align="a

Vinil7 [7]

Answer:

$t_{H} = t_{T} - 60$

Explanation:

Thinking process:

Let:

distance = speed × time

for the hare:

$d_{H} = s_{H} t_{H}$

for the tortoise:

$d_{T} = s_{T} t_{T}$

Let the length of the shell be s. Then the two are related. So:

$d_{H} = d_{T} - s$

Let's say the hare ran at x times the speed of the tortoise:

$s_{H} = xs_{T}$

So, the equation still holds : $t_{H} = t_{T} - 60$
