Explain in your own words how the light reflects and absorb transmitted, give example
Draw a example of non-luminous and luminous object.
find the potential gradient between two parallel plate conductor of separation 0.03 when potential difference of 540 supplied to them hence determine the force in an electron which club between the plates
A large pot contains 5.00×10−3 m3 of water at 23.0 °C. How much thermal energy must be removed from the water to freeze it into ice at 0.00 °C (in MJ)? [Latent heat of fusion for water: 333.4 kJ kg−1 , specific heat of water: 4190 J kg−1 K−1 , density of water: 1000 kg m−3 .]
The specific weight of an unknown liquid is 12 400 N/me. What mass of the liquid is contained in a volume of 500 cm3? Use: the minimum value of gravity on the earth
Andrea has a particularly old bike, and she has not lubricated the chain or gears. This causes friction inside the gears as she rides. She begins coasting on flat ground at a speed of 10 m/s, and after a few seconds is only going 8 m/s. How much energy has been converted to heat?
