Answer:
Speration between the slits
Explanation:
Given that,
Wavelength of light,
It is incident on a double slit produces a second-order maximum at an angle of 25 degree.
The condition for maxima is given as :
d = seperation between the slits
m = order, m = 2
d = 0.00000289
or
So, the seperation between the silts is
. Hence, this is the required solution.

Answer:
-3.396 m/s or 3.465 m/s
Explanation:
v = Speed of sound in air = 343 m/s
= Relative speed of the singer
f = Observed frequency
f' = Actual frequency
1% change can mean 
From the Doppler effect equation we have

The velocity is -3.396 m/s
when 

The velocity is 3.465 m/s
Answer:A 2.2kg block of ice slides across a rough floor. Its initial velocity is 2.5m/s and its final velocity is 0.50m/s. How much of the ice block melted as a result of the work done by friction? (Latent Heat of water is 3.3*10^5J/kg)
