Find the elongation produced in a copper wire of length 2m and radius 5mm, when suspended by a block

igomit [66]

Answer:

0.104 m

Explanation:

Stress, $\sigma=\frac {F}{A}$

Where F is force and A is area. Also, F=mg where m is mass and g is acceleration due to gravity

$Area= \pi r^{2}$

$Strain=\frac {\triangle l}{l}$ where $\triangle l$ is the elongation and l is the original length

$E=\frac {stress}{strain}=\frac {\frac {F}{A}}{\frac {\triangle l}{l}}=\frac {Fl}{A\triangle l}$

Making $\triangle l$ the subject then

$\triangle l=\frac {Fl}{AE}=\frac{mg l}{\pi r^{2} E}$

By substituting the given values and taking g as 9.81 then

$\triangle l=\frac {Fl}{AE}=\frac{500\times 9.81\times 2 m}{\pi \times 0.005^{2}\times 1.2\times 10^{9}}=0.104087333 m\approx 0.104 m$

What is the magnitude of the electric field at the origin produced by a semi-circular arc of charge = 7.6 μc, twice the charge o

Anna [14]

Orient the semi-circle arc such that it is symmetric with respect to the y-axis. Now, by symmetry, the electric field in the x-direction cancels to zero. So the only thing of interest is the electric field in the y-direction.

dEy=kp/r^2*sin(a) where k is coulombs constant p is the charge density r is the radius of the arc and a is the angular position of each point on the arc (ranging from 0 to pi. Integrating this renders 2kq/(pi*r^3). Where k is 9*10^9, q is 9.8 uC r is .093 m

When a plane flies with the wind, it can travel 1575 miles in 3.5 hours. when the plane flies in the opposite direction, again

Zepler [3.9K]

When plane is flying along the wind then we can say

$V_{plane} + v_{wind} = \frac{distance}{time}$

$V_{plane} + v_{wind} = \frac{1575}{3.5}$

$V_{plane} + v_{wind} = 450 mph$

Now when its going against the wind the speed is given by

$V_{plane} - v_{wind} = \frac{distance}{time}$

$V_{plane} - v_{wind} = \frac{1575}{4.5}$

$V_{plane} - v_{wind} = 350 mph$

Now by the above two equations we will have

$V_{plane} = 400 mph$

$v_{wind} = 50 mph$

Similarities Between Theory And Law

antoniya [11.8K]

Like theories, scientific laws describe phenomena that the scientific community has found to be provably true. Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, whereas theories describe how the phenomenon happens.
