I'd say B since headland since whenever there's a crash wave, headland receives most of the impact
Answer:
161.86 N
Explanation:
mass of box m= 55.0 kg
weight of the box, mg= 55×9.81
g here is acceleration due to gravity =9.81 m/sec^2
coefficient of friction between the box and the surface μ= 0.3
the friction force F_s= μmg= 0.3×55×9.81
=161.86 N
to move the ball horizontal force required is 161.86 N
In order to be considered a vector, a quantity must include Magnitude (A) and Direction (D).
Answer:
C. Waves transfer energy, but not matter.
