Answer:
Current, I = 1200 A
Explanation:
It is given that,
Length of the cylinder, l = 40 m
Radius of the metal wire, r = 4 mm = 0.004 m
Voltage source, V = 16 V
Resistivity of metal,
We know that the resistivity of any metal is given by the formula as :


R = 0.01336 ohms
Using ohm's law :



I = 1197.60 A
or
I = 1200 A
So, the current flowing in the cylindrical wire is 1200 A. Hence, this is the required solution.
Explanation:
The given data is as follows.
M = 35 kg, radius (r) = 2.2 m,
m = 17 kg, = 11 rad/s
We assume that will be the final angular speed.
Now, according to the conservation of angular momentum.

or, 
Putting the given values into the above formula as follows.

or,
=
= 7.58 rad/s
Thus, we can conclude that the angular speed of the clay and turntable is 7.58 rad/s.
Answer:the hare slept for 1 hr 55minutes.
Explanation: distance is changed to meters = 520m
Speed=distance/time
Speed of tortoise is 0.075m/s=520m/t
Crops multiplying t= 520/0.075 = 6933.3 seconds.
Speed for hare 16.7m/s =260m/t
ie 260m is half of the distance.
t =15.56seconds
Therefore the time slept by the hare = 6933.3- 15.56= 6917.74 seconds.
Converting to hours = 1hr. 55minutes is the time the hare slept.
