As we know that, the total distance covered, S = final reading of odometer – initial reading of odometer = (4460 – 4200) km = 260 km Total displacement = 0 km Total time taken, t = 4 h 20 ...

The nucleus has a two-layered covering called the nuclear membrane. The nuclear membrane contains pores that allow the transfer of material from inside the nucleus to the outside.

The conducting tissues in plants conduct different juices and have different structures. The primary conducting tissues of plants are xylem and phloem. The xylem carries water from the roots to other parts of the plant, while the phloem carries food ...

Among the given statements, statement [C] is not true because the constitutes of compound cannot be separated by simple physical methods.

Lateral meristem is present on the lateral sides of stems and roots. It helps in increasing the girth of stem and root.

(i)P is a compound. (ii) X and Y are compounds. (iii)X and Y are elements. (iv)P has a fixed composition.

Slope of velocity time graph gives acceleration. Because slope of the curve = v/t, where v/t = acceleration.

When a horse pushes the ground backwards (as action), then ground forces back the horse (as reaction) in forward direction. Due to this, the horse is able to pull a Tanga in forward direction.

If, m = 1 kg, F = 1 N, then, F = ma Or, 1 N = 1 kg x a Or, a = 1 N/ 1 kg = 1 kg – ms⁻²/ 1 kg = 1 ms⁻²

Given, u = 60 km/h = 60 x 5/18 m/s = 50/3 m/s, T = 1.6 s, V = 0 Average Acceleration: a = v – u/t = -50/ 3 x 1.6 = – 100/ 3 x 3.2 = – ...
