Answer:Michael Faraday  & Joseph Henry

Explanation:

Michael Faraday  & Joseph Henry both discovered Electromagnetic induction Working independently in Britain and United states respectively.Both discover that  current could be induced in a wire by moving a magnet in or out of a coil of wire.Henry develop the electromagnet in a practical device and laid the foundation of Electrical telegraph invented by Samuel F. B. Morse and Sir Charles Wheatstone, separately.

How many electrons are in an Sn+2 ion?
Veseljchak [2.6K]

Sn is Tin which has 50 atomic number

it means it has 50 electrons in its outer shells

+2 shows its valency

plus sign comes when electrons are removed from an atom

so here 2 electrons are removed from Sn atom

remaining electrons are 50-2

48 electrons

Vladimir [108]

Answer:

v=4m/s

Explanation:

The formulas for accelerated motion are:

v=v_0+at\\x=x_0+v_0t+\frac{at^2}{2}

We can derive the formula v^2=v_0^2+2ad from them.

We have:

v-v_0=at\\t=\frac{v-v_0}{a}

And substitute:

x=x_0+v_0(\frac{v-v_0}{a})+\frac{a}{2}(\frac{v-v_0}{a})^2\\x-x_0=\frac{v_0(v-v_0)}{a}+\frac{(v-v_0)^2}{2a}\\2a(x-x_0)=2v_0(v-v_0)+(v-v_0)^2=2v_0v-2v_0^2+v^2+v_0^2-2vv_0=v^2-v_0^2

Where in the first step of the last row we just multiplied everything by 2a. Since x-x_0 is the displacement d, we have proved that v^2=v_0^2+2ad

We use then our values to calculate the final velocity when starting from rest, traveling a distance 0.002m with acceleration 4000 m/s^2:

v=\sqrt{v_0^2+2ad}=\sqrt{2(4000m/s^2)(0.002m)}=4m/s
