A clear glass panel can become a mirror by simply being coated with silver on its back surface, which creates images by reflection. You can also use mirror-effect spray paint. Hope I helped some :)

lord [1]

Distance covered is given as follows

1). 7 km North

2). 5 km North

3). 1 km East

Now total distance covered will be given as

d = d_1 + d_2 + d_3

d = 7 km + 5 km + 1 km

d = 13 km

Now in order to find the displacement we will show all with their directions

\vec d_1 = 7 + 5 = 12 km towards North

\vec d_2 = 1 km towards East

So total displacement is

\vec d = \vec d_1 + \vec d_2

\vec d = 12 \hat j + 1 \hat i

so net displacement will be

d = \sqrt{12^2 + 1^2} = 12.04 km

so displacement is 12.04 km

An amoeba has 1.00×1016 protons and a net charge of 0.300 pC. (a) How many fewer electrons are there than protons? (b) If you pa
ladessa [460]

Explanation:

(a)   It is known that charge on a proton is equal to 1.6 \times 10^{-19} C. And, net charge is given as 0.3 pC which is also equal to 0.3 \times 10^{-12}C.

Therefore, we will calculate the number of electrons as follows.

           \frac{0.3 \times 10^{-12}C}{1.6 \times 10^{-19}C}

            = 1.87 \times 10^{6}

Hence, there are 1.87 \times 10^{6} fewer electrons are there than protons.

(b)   Now, we will calculate the fraction of protons that would have no electrons as follows.

               \frac{1.88 \times 10^{6}}{1 \times 10^{16}}

               = 1.88 \times 10^{-10}

Therefore, fraction of the protons that would have no electrons is 1.88 \times 10^{-10}.

A 580-mm long tungsten wire, with a 0.046-mm-diameter circular cross section, is wrapped around in the shape of a coil and used
serious [3.7K]

Answer: 1.64 *10^19 electrons

Explanation: In order to the explain this problem we have to consider the following:

The current= charge/time; so

as the electrons move in the tungsten wire we have:

0.526 C/s= N electrons per second* charge of electron=

N electrons/s= 0.526/1.6*10^-19= 3.28 *10^18 electrons/s

Then, during  5 seconds  will pass:

3.28 *10^18 electrons/s*5 5s= 1.64 *10^19 electrons
