Rukshar painted the outside of thr cabinet of measure ` 1m xx 2m xx 1.5m`.How much surface area did she cover if she painted all expect the bottom of the cabinet?

A table-top measurs 2 m by 1 m 50 cm. What is its area in square metrea ?

In Millikan's oil drop experiment. What is the terminal speed of an uncharged drop of radius 2.0 times 10^-5 m and density 1.2 times 10^3 kg m^-3 . Take the viscosity of air at the temperature of the experiment to be 1.8 times 10^-5 Pa s . How much is the viscosity force on the drop at that speed? Neglect buoyancy of the drop due to air.

Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8 m above the surface of water and the fly at the end of the string rests on the water 3.6 m away and 2.4 m from a point directly under the tip of the rod. Assuming that her rod to the fly) is taut, how much string does she have out(see fig)? If she pulls in the string at the rate of 5 cm per second, what will be the heriozontal distance of the fly from her after 12 seconds.

A godown measures 40 m xx 25 m xx 15m. Find the maximum number of wooden creater each measureing 1.5 m xx 0.5 m that can be stored in the godown.

A bus stop is barricaded from the remaining part of the road, by using 50 hollow cones made of recyled cardboard. Each cone has a base diameter of 40 cm and height 1 m. If the outer side of each of the cones is to be painted and the cost of painting is Rs 12 per m^(2) , what will be the cost of painting all these cones ? ("Use"pi=3.14)" and take "sqrt(1.04)=1.02)

The radius of a hydrogen atom is 5.32 xx10^(-11) m and the radius of a proton at the centre is 1.5 xx 10^(-5) m. The ratio of the radius of the atom to the radius of proton is :

A fully loaded boeing aircraft has a mass of 3.3 times 10^5 Kg . Its total wing area is 500 m^2 . It is in level flight with a speed of 960 km//h (a) Estimate the pressure difference between the lower and upper surfaces of the wings (b) Estimate the fractional increase in the speed of the air on the surface of the wing relative to the lower surface.[ The density of air is p= 1.2 kg m^-3 ]

The paint in a certain container is sufficient to paint an area equal to 9.375m^(2). How many bricks of dimensions 22.5cmxx10cmxx7.5cm can be painted out of this countainer ?

Shubham painted 2/3 of the wall space in his room. His sister Madhavi helped and painted 1/3 of the wall space. How much did they paint together?
