Suppose you have measured the diffraction pattern of a grating with d = 0.19 mm and have found that the spots were separated by
cestrela7 [59]

Answer:

d = 0.076 mm

Explanation:

Given data

diffraction pattern d1 = 0.19 mm = 0.019 cm

separated s(1)  = 1.8 cm

separated s(2) = 4.5 cm

to find out

d2 for an unknown

solution

we know here that spacing in between the diffraction fringe is always inversely proportional to diffraction grating so

we will apply here formula for unknown d that is

d1 (s1 / L) = d2 (s2 /L)

d2  = d1 ×  s(1) / s(2)

put here all thes evalue we get d2

d2  = d1 ×  s(1) / s(2)

d2  = 0.019 ×  1.8  / 4.5

d2 = 0.0076 cm

d2 = 0.076 mm

Write a hypothesis about the effect of temperature and surface area on the rate of chemical reactions using this format: “If . .
grandymaker [24]
Effect of temperature.

"If the temperature of the substance is increased then the rate of chemical reaction is also increased because the kinetic energy is greater."

Effect of surface area.

"If the surface area is increased then the rate of reaction is increased because there will be more active sites for the reaction to occur.

A strong lightning bolt transfers an electric charge of about 16 C to Earth (or vice versa). How many electrons are transferred?
zzz [600]

Answer:

Number of electrons, n=9.98\times 10^{19}

Explanation:

A strong lightning bolt transfers an electric charge of about 16 C to Earth, q = 16 C

We need to find the number of electrons that transferred. Let there are n electrons transferred. It is given by using quantization of electric charge as :

q = ne

n=\dfrac{q}{e}

e is elemental charge

n=\dfrac{16}{1.602\times 10^{-19}}

n=9.98\times 10^{19}

So, there are 9.98\times 10^{19} electrons that gets transferred. Hence, this is the required solution.
