Answer:
The dominant wavelength of the sun is 
Explanation:
Wien's law is defined as:
(1)
Where
is the maximum wavelength, c is the Wien's constant and T is the temperature.
Therefore,
can be isolated from equation 1.
(2)

Notice that it is necessary to express the Wien's constant in units of meters
⇒ 
Finally, equation 2 can be used:


Hence, the dominant wavelength of the sun is
Answer:
Explanation:
given,
mass of block = 3 kg
spring constant k = 500 N/m
kinetic friction coefficient µk = 0.6
speed of block = 5 m/s
F = µk N
F = 0.6 x 3 x 9.8
F = 17.64 N
using energy conservation


250 x² + 17.64 x - 37.5 = 0
on solving
x = 0.354 m
graph is attached below

Answer
given,
Hunk Finn speed,v_y= 0.7 m/s
Speed of river,v_x = 1.50 m/s
Assuming the speed of the river is in x-direction.
Speed of Hunk Finn to be in y-direction.
Hunk velocity relative to river =



Speed of Hunk relative to river = 1.66 m/s
direction of the boat



Hence, angle of the raft is 24.01°
