The particle nature of light is demonstrated through the photoelectric effect. The amount of light that is emitted is dependent on its intensity. According to the theory of light's particle nature, light is made up of "photons,"

Correct Answer: Right isosceles triangle

Solution : AB = $k$
BC = $k$
AC = $\sqrt2k$
⇒ AB² = $k^2$
⇒ BC² = $k^2$
⇒ AC² = $2k^2$
$\therefore$ AB² + BC² = AC² and AB = BC
By Pythagoras theorem, $\triangle$ ABC is

Correct Answer: 21 cm

Solution :
AD is the median of triangle ABC.
G is the centroid of triangle ABC.
If AG = 14 cm
So, $\frac{AG}{GD}=\frac{2}{1}$
⇒ $\frac{14}{GD} = \frac{2}{1}$
⇒ $GD =7$ cm
$\therefore$ AD = AG + GD = 14 + 7 = 21 cm
Hence, the

Correct Answer: IJK

Solution : Let's check the options –
First option: IJK→I + 1 = J; J + 1 = K
Second option: GIK→G + 2 = I; I + 2 = K
Third option: LNP→L + 2 = N; N + 2 = P
Fourth option: TVX→T +

Correct Answer: $45^\circ, 45^\circ$

Solution : Given: $\cos(A+B)=0$ and $\sin(A-B)=0$
The equation $\cos(A+B)=\cos 90^\circ$
$A+B=90^\circ$............(equation 1)
The equation $\sin(A-B)=\sin 0^\circ$
$A-B=0^\circ$............(equation 2)
Solving these two equations, we get:
$\angle A = \angle B = 45^\circ$
Hence, the correct answer is $45^\circ, 45^\circ$.
