Answer: All light strikes an opaque object will be absorbed by the object.

Explanation:

Transparent objects are the ones which allow light rays to completely pass through them.

Translucent objects are the ones which allow the light rays to pass through them but the objects on the other side cannot be seen clearly.

Opaque objects are the ones which does not allow the light rays to pass through them. In other words, all the light rays gets absorbed by the object.

Hence, All light strikes an opaque object will be absorbed by the object.

Choose the statement(s) that is/are true about the ratio \frac{C_p}{C_v} C p C v for a gas? (Ii) This ratio is the same for all

Blababa [14]

Answer:

(i) false

(ii) true

(iii) true

(iv) false

Explanation:

(i) The ratio of Cp and Cv is not constant for all the gases. It is because the value of cp and Cv is different for monoatomic, diatomic and polyatomic gases.

So, this is false.

(ii) For monoatomic gas

Cp = 5R/2, Cv = 3R/2

So, thier ratio

Cp / Cv = 5 / 3 = 1.67

This statement is true.

(iii) for diatomic gases

Cp = 7R/2, Cv = 5R/2

Cp / Cv = 7 / 5 = 1.4

This statement is true.

(iv) It is false.

vector: (-3,-2)

Scalar: -6

so the vector multiplied by the scalar will have components
