Answer:
Length = 2.92 m
Diameter = 0.11 mm
Explanation:
We have , where:
is the length
We divide the first equation by the second equation to get:
Using this Area, we find the diameter of the wire:
To find the length, we multiply the two equations stated initially:
Answer:
The acceleration is a = 2.75 [m/s^2]
Explanation:
In order to solve this problem we must use kinematics equations.
where:
Vf = final velocity = 13 [m/s]
Vi = initial velocity = 2 [m/s]
a = acceleration [m/s^2]
t = time = 4 [s]
Now replacing:
13 = 2 + (4*a)
(13 - 2) = 4*a
a = 2.75 [m/s^2]
