Answer:
Potential gradient = 1.6 v/m
E.M.F. = potential gradient × balancing length 1.2 = 1.6 × l
l=1.2\1.6
=3\4
3\4=0.75m
convert m into cm 0.75x10
0.75m=75 cm
ans=75 cm
Explanation:
Answer:
2.6 g/cubic centimeter
Explanation:
Given :
Weight of the quartz = 13 gram
Original level of water = 30mL
Level of water after quartz was is placed inside the cylinder = 35 mL
Therefore rise in water = 35 - 30 = 5 mL
We known that 1 mL = 1 cubic centimeter
And density = mass / volume
Therefore, density of the quartz is = 13/5
= 2.6 g/ cubic centimeter

The definition of a scale of 1: 166 will mean that the scale of 1 in the model will be equivalent to 166 times the measurement in the real model, therefore we will have that the height would be 166 times smaller than the 179m given:
The same for the diameter,
The volume of a cylinder is given as
Therefore the volume would be
