Earth WUUIU Uoriginal mass?Ans: ~ 12 hrsIf the height of a satellite completinone revolution around the earth inseconds is h, meter, then what woulbe the height of a satellite taking2/2 T seconds for one revolution?Ans: R+ 2hject : |
|
Answer» Answer: plz mark as brainliest and follow me please Explanation:•Kepler's Third LAW: The cube of the MEAN distance of a planet from the sun is directly proportional to the square of time TAKEN to move around the sun. where , r is the mean distance from the sun •°•°•°•°•°<><><<><>><><>°•°•°•°•°•° ¶¶¶ SOLUTION: Given, height of satellite = m time taken by satellite for one revolution around earth = T sec When satellite takes seconds for one revolution, height of satellite = ? Cross Multiply 8(R+h_{1})^{3} = (R+h_{2})^{3} \implies 2^{3}(R+h_{1})^{3} = (R+h_{2})^{3} \implies (2(R+h_{1}))^{3} = (R+h_{2})^{3} \implies (2R+2h_{1})^{3} = (R+h_{2})^{3} APPLYING cuberoot on both sides, we get \implies 2R+2h_{1} = R+h_{2} \implies h_{2} = 2R+2h_{1}-R \implies h_{2} = R+ 2h_{1} •°• If satellite takes 2\sqrt{2}T seconds for one revolution, then height of satellite = R+2h_{1}

A copper block of 2 kg is heated in a furnace from 30°C to 430°C and then placed on thick ice block. Calculate specific heat of copper if ice melted is 1Kg |
|
Answer» Answer: PHYSICS A copper block of mass 2.5 kg is heated in a FURNACE to a temperature of 500 o C and then placed on a large ICE block. What is the maximum amount of ice that can MELT ? (Specific HEAT of copper=0.39Jg −1 K −1 ; heat of fusion of water =335Jg −1 ) November 22, 2019avatar Mitesh Ramekar SHARE VIDEO EXPLANATION ANSWER Mass of the copper block, m=2.5kg=2500g Rise in the temperature of the copper block, =500 o C Specific heat of copper, C=0.39J/g o C Heat of fusion of water, L=335J/g The maximum heat the copper block can lose, Q=mC =2500×0.39×500 =487500J Let m 1
g be the amount of ice that melts when the copper block is placed on the ice block. The heat gained by the melted ice,Q=m 1
L m 1
=Q/L=487500/335=1455.22g Hence, the maximum amount of ice that can melt is 1.45 kg |
