Explanation:
Resistance of the tungsten wire
R = resistivity x length / cross sectional area
=
= 107 x 10⁻⁴ ohm
Resistance at 120 degree can be obtained from the following formula
= 155.15 x 10⁻⁴ ohm
= 160 x 10⁻⁴ ohm ( rounding off to two syg fig )
current = 12.5
potential diff = 12.5 x 155.15 x 10⁻⁴ V
= 0 .1939 V
= .19 V
required electric field = potential diff / length of wire
= .1939 / 16 x 10⁻²
= 1.2 N / C
Explanation:
It is given that,
Weight of the rock in air, W = 110 N
Since, W = mg
m = 11.22 kg
We need to find the apparent weight of the rock when it is submerged in water. Apparent weight is equal to the weight of liquid displaced i.e.
d is the density of water,
V is the volume of rock,
M = 3.37 kg
The apparent weight in water, W = m - M
W = 76.93 N
So, the apparent weight of the rock is 76.93 N. Hence, this is the required solution.
