is the density of the substance which has 5gm and in an area of 12cm, 10cm and 2cm.
To find the density of a substance, we know that density is the ratio of mass of the substance and volume of the substance. Hence, given that mass of the substance is 5gm and volume of the substance is 12cm×10cm×2cm =240
Therefore, we came to know that density of the substance which has mass and volume can be found by using the above formula. is the density of the substance whose mass is 5gm and volume is 240 .
A) SOBDM/BCCM (I Think)

Connecting a resistor in series with battery will cause the battery voltage to drop.
voltage across resistor= 12-3.6= 8.4
Current in the circuit= 0.15A
From the bunch of resistors, I will make a combination of 56Ω
