A spring balance measures the weight of an object in air to be `0.1N` .It shows a reading of `0.08N`, when the object is completely immersed in water. If the value of acceleration due to gravity is,`10m//s^(2)` ,the volume of the object is
(1) `20cm^(3)`
(2) `80cm^(3)`
(3) `200cm^(3)`
(4) `2cm^(3)`

Suppose the acceleration due to gravity at a place is 10 m/s^2 . Find its value in cm//(minute).

An object of mass 26 kg floats in the air and it is in the equilibrium state.Air density is 1.3 kg m^(-3) . The volume of the object is

A spring balance reads forces in Newton. The scale is 20 cm long and read from 0 to 60 N. Find potential energy of spring when the scale reads 20 N.

Density of an object is g//cm^(3) . Express it in kg//m^(3) .

An object lies 100 cm inside water (mu=4//3) . It is viewed from air nearly normally. Find the apparent depth of the object.

The chart above shows approximate of the acceleration due to gravity in meters per second squared (m/(sec^(2))) for the eight planets in our solar system. The weight of an object on a given planet can be found by using the formula W=mg, where W is the weight of the object measured in newtons, m is the of the object measured in kilograms, and g is the acceleration due to gravity on the planet measured in m/sec^(2) . An object on Earth has a weight of 150 newtons. On which planet would the same object have an approximate weight of 170 newtons?

Density of water is ...… ("10 g cm"^(-3)//"1 g cm"^(-3)) .

A fish in water sees an object which is 24cm above the surface of water. The height of the object above the surface of water that will appear to the flash is (mu=4//3)

The chart above shows approximate of the acceleration due to gravity in meters per second squared (m/(sec^(2))) for the eight planets in our solar system. The weight of an object on a given planet can be found by using the formula W=mg, where W is the weight of the object measured in newtons, m is the of the object measured in kilograms, and g is the acceleration due to gravity on the planet measured in m/sec^(2) . What is the weight, in newtons, of an object on Mercury with a mass of 90 kilograms?

A point object is placed at a distance of 20 cm from a glass slab, H=18cm, half immersed in water as shown in figure. The distance between two images when seen from the other side of the slab is (mu_(g) = (3)/(2) and mu_(w) = (4)/(3))
