Answer:
Explanation:
he answer is 540 because you need to do the area of the wall times six. 15 times 6 times 6 equals 540
Field lines become straight and perpendicular because every point of circular loop the concentric circles become larger and larger as we move away from the wire.
centrifugal force is a fictitious force. What is happening is that since the earth itself is not a rigid body it will deform when under motion. Although gravity attempts to make the earth spherical, as it is rotating the earth deforms, in such away that it flattens to become an oblique spheroid. This happens as the material at the equator must have a net resultant centripetal force (not centrifugal) which causes its position of equilibrium from the center of the earth to be further away than at the poles as they do not have this force as they are not rotating around the center of mass.
Answer:
n = 1.76
Explanation:
According to the rule of ( n1 sin theta1 = n2 sin theta2 )
we know both angles so we insert them to the law and apply n1 = 1
so 1/2 = n2 sin 62 and we get the final answer
Answer:
a) 1.95 m/s
b) 5.56 m
Explanation:
Given that:
Velocity of the skier 
= 14.3 m/s
For the skier moving in the direction of the wave, we have:
Period (T) = 0.450 s
Relative velocity (V) of the skier in regard with the wave = 
where:
= velocity of the skier
= velocity of the wave
The wavelength 
can be written as:
---------------> Equation (1)
For the skier moving opposite in the direction of the wave, we have:
Period (T) = 0.342 s
Relative velocity (V) of the skier in regard with the wave = 
The wavelength can be written as:
------------------> Equation 2
Equating equation (1) and equation (2) and substituting = 14.3 m/s ; we have:
Collecting the like terms; we have:
b)
The Wavelength of the wave can be calculated using : 
λ ≅ 5.56 m
