Answer:
Negligible weights is a change so minor or insignificant to be deemed to have no effect on weight or balance.
The block of wood is 3cm on each side so it is a cube. The volume of a cube is given by s^3. So the volume of this block is 3cm x 3cm x3 cm = 27 cm^3. density = mass/volume =27 g / 27 cm^3 = 1 g/cm^3
A window is the most transparent object from these, so that is the answer.
Given :- A resistor of 150 ohm, hence Resistance (R) = 150 ohm
Potential Difference (v) = 24 V
Current (I) = ?
V = IR
24 = I × 150
I = 24/150
I = 0.16 ampere
hope it helps!
