Two vectors A and B are such that A+B=C and A₂+B₂ = C₂. Which of the following statements is correct?

A particle is moving eastward with a velocity of 5 m/s. In 10 seconds, the velocity changes to 5 m/s northwards. The average acceleration in this time is

A truck travelling due north at 30 m/s turns west and travels at the same speed; then the change in velocity is

Two forces each numerically equal to 10 dynes are acting as shown in the following figure, then the resultant is

Volume of a Cuboid is 30 cm³ and its = 5 cm, b = 3 cm Find its height

Therefore, the height of the cuboid is 2 cm.

Find the altitude of a triangle whose base is 20 cm and Area is 150 cm²

Therefore, the height of the triangle is 15cm.

ABCD is a Parallelogram DL AB and DM BC If AB = 18 cm, BC=12 cm and DM = 9 cm then find DL .

ABCD is a Parallelogram, DL AB If AB = 20 cm, AD = 13 cm and area of the Parallelogram is 100 cm², find AL.

The base of a Parallelogram is twice its height If the area of the Parallelogram is 512 cm², then find the height

Therefore, height of the parallelogram is 16cm.
