Answer:
64.1°
Explanation:
Coefficient of friction = Horizontally resolved pushing force divided by Moving force
Coefficient of friction is 0.437
Resolving pushing force to horizontal = Moving force * Cos ∅
Therefore, 0.437 = Cos ∅
and ∅ = Arch Cos 0.437 = 64.1°
Waves transfer energy not matter. so simply put, the water doesn't move. it's just being used as a road that energy uses to get from point a to b. it's easier to think of some thing on the water rather than the water it self. like a cork floating on the surface. when a wave passes through the cork. the cork goes up to the peak of the wave and then down to the trough of the wave and then back at equilibrium. it only moved up and down since it was following the wave pattern. if the waves transfered matter as well as energy then the cork would begin to get pushed by the wave and move towards the direction of travel
I think it is Letter D, because she already said what to make
Answer:
<em>The product of the object's weight and the horizontal distance between the two positions.</em>
<em></em>
Explanation:
Work is the product of force and the distance through which this force is moved. The distance moved can be vertical, or horizontal. For two bodies located the same distance from the center of the earth, the work done will be the product of the weight of the product and the horizontal distance between the two positions. <em>If the vertical work is needed, then the work is zero, since there is no height gradient between them</em>.
