Physics A parallel-plate capacitor of capacitance C1 is made using two gold plates. Another parallel-plate capacitor of capacitance C2 is made using two aluminium plates with same plate separation, and all the four plates are of same area. If rg and ra are respectively the electrical resistivities of gold and aluminium, then which one of the following relations is correct? C1pa = C2pg C2>C1 C1 = C2 C1>C2 C1pa = C2pg C2>C1 C1 = C2 C1>C2 ANSWER DOWNLOAD EXAMIANS APP
Physics It is easier to roll a stone up a sloping road than to lift it vertical upwards because Work done in rolling is more than in lifting. Work done in rolling a stone is less than in lifting it. Work done in both is same but the rate of doing work is less in rolling. Work done in lifting the stone is equal to rolling it. Work done in rolling is more than in lifting. Work done in rolling a stone is less than in lifting it. Work done in both is same but the rate of doing work is less in rolling. Work done in lifting the stone is equal to rolling it.
