WebMetallic spheres of radii 6 cm, 8 cm and 10 cm, respectively, are melted to form a single solid sphere. Find the radius of the resulting sphere. Solution: For Sphere 1: Radius (r 1) = 6 cm ∴ Volume (V 1) = (4/3)×π×r 13 For Sphere 2: Radius (r 2) = 8 cm ∴ Volume (V 2) = (4/3)×π×r 23 For Sphere 3: Radius (r 3) = 10 cm ∴ Volume (V 3) = (4/3)× π× r 33
WebThis cohesive force is different for different materials. If a drop of water and oil is gently dropped on a flat surface, the droplet of water will tend to be more spherical whereas the oil droplet will be a bit flatter. This happens because water has higher surface tension and hence it becomes able to pull the volume of liquid together more ... WebNCERT Solutions for Class 9 Science Chapter 1 Matter in Our Surroundings 4. Liquids generally have a lower density than solids. But you must have observed that ice floats on water. Find out why. Solution: In general, the volume of a liquid is more than the volume of a solid because liquid particles are freer to move, resulting in more volume.
WebThe volume of a cube = base area × height. Since all dimensions are identical, the volume of the cube = a3 Where a is the length of the edge of the cube. Volume of a Right Circular Cylinder The volume of a right circular cylinder is equal to base area × its height. The volume of cylinder =πr2h WebWe know that the surface area of a cuboid = 2 (lb + lh + bh) But here the bottom part is not to be painted. So, Surface area of box to be painted = lb + 2 (bh + hl) = 2 × 1 + 2 (1 × 1.5 + 1.5 × 2) = 2 + 2 (1.5 + 3.0) = 2 + 9.0 = 11 Hence, the required surface area of the cuboidal box = 11 m 2 8.

WebLet, the radius and height of the cylinder ber and h respectively. ∴ Volume of the original cylinder=πr2h. According to the question, New radius = r and new height = 2h. ∴ Volume of the new cylinder =π(r)2(2h) = 2πr2h. ⇒ The volume will become double of the original volume. Hence, option (A) is the correct answer.
