Explanation

Temperature increases or decreases the kinetic energy of particles, leading to melting, boiling, or freezing.

Pressure affects the arrangement of particles, especially in gases, influencing condensation or compression.

Explanation

Profit = 5000 - 4000 = Rs. 1000

Profit % = (1000 / 4000) × 100 = 25%

Explanation

The discriminant D = b^2 - 4ac = 1^2 - 4(4)(1) = 1 - 16 = -15.

Since D = -15 < 0, the roots are Imaginary and unequal.

Explanation

Calculate the cube root of 32768.

³√32768 = ³√32³ = 32

Explanation

Total admissions = 1250

Graphic designing = 400

Painting = 200

Calligraphy = 500

Total for these three = 400 + 200 + 500 = 1100

Admissions for baking = 1250 - 1100 = 150

Fraction for baking = 150 / 1250

= 3 / 25

Explanation

Given CF = 24 and the centroid G divides CF in a 2:1 ratio, with the longer part toward the vertex C and the shorter part toward the midpoint F of side AB.

The total length CF is divided into 3 parts, where 2 parts are toward the vertex (CG) and 1 part is toward the midpoint (FG).

FG = (1/3) × CF = (1/3) × 24 = 8.

Explanation

A star with an initial mass more than five times that of the Sun ends its life as a black hole after a supernova explosion.

Its gravitational pull becomes so strong that not even light can escape.

Explanation

Let's simplify the expression:

√1-sin²θ/sinθ = √(cos²θ)/sinθ (since 1 - sin²θ = cos²θ)

= cosθ/sinθ

= cotθ
