Answer:
the velocity of the kid is 5.6 m/s
Explanation:
r is the radius and w is the frequency.
so we should know that the diameter is 18m and the diameter is equal to two times the radius, so r = 18m/2 = 9m
we should also know that the circumference of a circle is equal to c = 2pi*r, so each revolution has this length. if the kid does 5.9 revolutions in one minute then the kid spins at v = 5.9*2pi*9m/min
so we want to write this in meters per second and this means that we need to divide it by 60!
v = (5.9*2pi*9/60)m/s = 5.56 m/s
so your answer will be 5.6 m/s glad i could help!

The light the fish absorbs is sunlight, the light reflecting is UV
A sample of water is taken and kept in a beaker in a freezer at a constant temperature of 0°C. If the system is at dynamic equilibrium, which of these statements is true?
Answer:
The magnitude of the applied force is 94.74 N
Explanation:
Mass of the block, m = 11 kg
Angle of inclination of the plane, 
Friction coefficient, 
Now,
Normal force that acts on the block is given by:
(1)
Now, to maintain the equilibrium parallel to ramp the forces must be balanced.
Thus
(2)
From eqn (1) and (2)
F = 94.74 N
I think it is b cause I don’t think you do that
