Answer: The expression $CaCO_{3}\rightarrow CaO+CO_{2}$ is an example of chemical reaction.

Explanation:

Given expression,

$CaCO_{3}\rightarrow CaO+CO_{2}$

This is the chemical equation.

We know that,

In this equation, $CaCO_{3}$ is the reactant and $CaO+CO_{2}$ is the product.

The substance initially present in the chemical reaction is called reactant and the substance formed by the reaction is called product.

Hence, The expression $CaCO_{3}\rightarrow CaO+CO_{2}$ is an example of chemical reaction.

A light ray is incident on a plane surface separating two transparent media of refractive indices of 1.65 and 1.35. If the incid

Vesna [10]

Explanation:

Given

Refractive Index $(n_1)=1.65$

$n_2=1.35$

angle of incident $=35 ^{\circ}$

Light originates in the medium of higher refractive index

Let $\theta _1$ and $\theta _2$ be the incident and refraction angles respectively thus according to snell's law

$n_1sin\theta _1=n_2sin\theta _2$

$1.65\times sin35=1.35\times sin\theta _2$

$sin\theta _2=0.701$

$\theta _2=44.507^{\circ}$

(b)Ray originates from lighter medium

$1.35\times sin35=1.65\times sin\theta _2'$

$sin\theta _2'=0.469$

$\theta _2'=27.96\approx 28^{\circ}$

What force does the water exert (in addition to that due to atmospheric pressure) on a submarine window of radius 44.0 cm at a d

Butoxors [25]

Calculate the pressure due to sea water as density*depth.
That is,
pressure = (1025 kg/m^3)*((9400 m)*(9.8 m/s^2) = 94423000 Pa = 94423 kPa

Atmospheric pressure is 101.3 kPa
Total pressure is 94423 + 101.3 = 94524 kPa (approx)

The area of the window is π(0.44 m)^2 = 0.6082 m^2

The force on the window is
(94524 kPa)*(0.6082 m^2) = 57489.7 kN = 57.5 MN approx
