The printing press had dramatic effects on European civilization. Its immediate effect was that it spread information quickly and accurately. This helped create a wider literate reading public.
Answer:
c. is negative
Explanation:
When the magnitude of force is multiplied with the force vector's projection along the direction of the vector of displacement which is negative as it is a resistive force we get the work done.
As the wind is acting in opposite direction of the force which is being applied by the plane the work done will be negative. Also, the net work will be the sum of many smaller negative quantities.
Hence, the answer here is negative.
Answer:
a tendency to do nothing or to remain unchanged.
Explanation:
Answer:
1) Height of bridge = 12.4 m
2) Velocity when the swimmers hit the water = 15.58 m/s
3) Time of flight if the bridge was 2.5 times as high = 2.52 s
Explanation:
Using the equations of motion,
g = 9.8 m/s², y = H = ? t = 1.59 s
Initial velocity, u = 0 m/s,
final velocity, v = ?
Total Time of fall, t = 1.59
1) y = ut + gt²/2
y = 0 + 9.8(1.59)²/2
y = 12.4 m
2) v = u + gt
v = 0 + (9.8 × 1.59)
v = 15.58 m/s
3) y = ut + gt²/2
y = 2.5 × 12.4 = 31 m
u = 0 m/s
g = 9.8 m/s²
31 = 0 + 9.8t²/2
4.9t² = 31
t² = 31/4.9
t = 2.52 s
