Answer: 50 V
Explanation:
Given
Three capacitors are connected in parallel across 50 V battery
When capacitor are connected in parallel, net capacitance is the sum of all the values
Net capacitance
Voltage in parallel circuit is same across each capacitor. Therefore, voltage across 4.7 F capacitor is 50 V
675g/cm³ is the density of the liquid
Here we have given that
density of wood be ρ.
the volume of the block be V
The volume of the block =1/4 v
The volume of the immersed block (v) =V-1/4V=3/4V
We know the weight of the block = the weight of the water displaced by the submerged part of the block.
i.e. V x ρ x g
= 3/4 x900g/cm³
= 675g/cm³
Density is a measure of mass divided by the volume of an object. Defined as mass per unit volume. here from the above equation we have substituted the given value and we got the answer as 675g/cm³

When glass is rubbed with a dry cloth, the friction creates charged static electricity; this in turn attracts small non charged particles of dust. The simplest way to put it, the dry cloth creates a static charge that attracts non charged dust particles.
