Path length is 2*pi*0.4=2.512
Speed=distance/time
Speed =2.512/0.2=12.56m/s
In order to describe motion along a straight line, you must state the speed and direction of the motion. Those two quantities, together, comprise what's known as "velocity".
Based on the description, it will be most likely that he believes in Oscillating model (also known as Cyclic model) of the universe
Based on this model, the gravitational force will prevent further expansion by pulling back the matters and undergo a bounce
hope this helps
Explanation:
The given data is as follows.
Resistance (R) = 1200 ohm, Area (A) = m (as )
Diameter (d) = 2.3 mm = m
First, we will calculate the length as follows.
R =
Here, = resistivity of aluminium =
Putting the given values above and we will calculate the value of length as follows.
R =
1200 =
L =
As the circumference of circular wire =
or, =
=
And, number of turns will be calculated as follows.
No. of turns × Circumference = Length of wire
No. of turns ×
=
Thus, we can conclude that turns of wire are needed.
