Answer:

Explanation:
Given that
Wavelength λ=192 nm
So energy of photon,E

Now by putting the values




We know that
Kinetic energy given as




Answer:
12.25 meters
Explanation:
s=1/2(v+u)t
s= displacement
v= final velocity
u= initial velocity
t= time
7m/s+0m/s divide by 2= 3.5 m/s velocity Times 3.5 seconds= 12.25 meters
The temp would affect the length of the wire
the length would affect how much support there is as well as the diameter of the wire
To measure acceleration, a stopwatch is used.
