Answer:
Tides on our planet are caused by the gravitational pull of the Moon and Sun. Earth's oceans "bulge out" because the Moon's gravity pulls a little harder on one side of our planet (the side closer to the Moon) than it does on the other. The Sun's gravity raises tides, too, but lunar tides are twice as big.
That's a weird graph, but judging from the units the acceleration is the slope of the graph.
a = (0.8 - 0.3)/(0.16 - 0.055) = 4.76 m/s²
Answer:
0 kgm/s
Explanation:
The momentum is the product of mass(m) and velocity(v).
Initially the velocity of truck is 0 m/s so the product of mass and velocity becomes 0.
It does not matter what is the weight of truck, because the velocity will make the product of m*v = 0
It does not matter what is the momentum of car.
Explanation:
As a tornado or other storm system passes over a building, low pressure can tug a roof upward. When those forces surpass the force exerted by the weight of the roof, the structure flies up and is swept away by wind currents..
