Answer:
C. There is a net horizontal force on the skier in the direction the boat’s velocity.
Explanation:
This is because, according to Newton's First law of motion, when an object which in this case is the skier tends to be in equilibrium because it travels at a constant velocity, there is no net acceleration of the skier, and this causes the net force on the skier to be equal to zero.
Therefore in this question, option C which states that "There is a net horizontal force on the skier in the direction the boat’s velocity" is a false statement.
Answer:
a) n2 = 1.55
b) 408.25 nm
c) 4.74*10^14 Hz
d) 1.93*10^8 m/s
Explanation:
a) To find the index of refraction of the syrup solution you use the Snell's law:
(1)
n1: index of refraction of air
n2: index of syrup solution
angle1: incidence angle
angle2: refraction angle
You replace the values of the parameter in (1) and calculate n2:

b) To fond the wavelength in the solution you use:

c) The frequency of the wave in the solution is:

d) The speed in the solution is given by:

Answer:
C. is responsible for sliding friction and contact forces
Answer:
A single component that can’t be separated
