electromagnet
When a electric current is passed through an insulated wire that is coiled around an iron core, like a nail, an electromagnet is created.
Answer:
we cant find the magnitude with just two coordinations.if that equation is y=mx....and we can think that these is also a cordintion (0,0)..because line cross the middle of the chart.then we can use the equation m= y difference/x difference
m=(4-0)(-3-0 )
m=4/(-3)
m=-1.333
The answer for “Why did Jim Bridger build a fort along the Oregon Trail” is D
Answer:
The scattering angle is 0.80
Explanation:
As we know
Wave length = h/mc (1-cos α) --1
W = mc^2
m = E/c^2
Substituting this in equation 1 we get
Wavelength = hc/E (1-cos α)
Substituting the given values, we get -
0.95*10^-9 = [(6.626 *10^-34 * 2.998 *10^8)/5.111*1000*1.6*10^-19} (1-cos α)
(1-cos α) = 1.14 *10^-10
cos α = 1- 1.14 *10^-10
α = 0.80
