<span>a tsunami travels at a speed that is related to the water depth - hence, as the water depth decreases, the tsunami slows. The tsunami's energy flux, which is dependent on both its wave speed and wave height, remains nearly constant. Consequently, as the tsunami's speed diminishes as it travels into shallower water, its height grows.</span>
Answer:
926 N
Explanation:
Metric unit conversion:
R = 18 cm = 0.18 m
r = 5 cm = 0.05 m
The pressure exerted by the F = 12000N car on the wider arm would be ratio of the gravity over area
The pressure must be the same on the smaller pressure for it to be able to start lifting the car. We can calculate the force f acting on it:
Answer:
F = 98 N
Explanation:
Data:
- Mass (m) = 14 kg
- Acceleration (a) = 7 m/s²
- Force (F) = ?
Use formula:
Replace:
Multiply both operations, with the units:
What is the amount of the force?
The amount of the force is <u>98 Newtons.</u>
The answer is D.
Most of the rotational and orbital motions in the solar system are in the same "eastward" direction. Motions in this direction are referred to as direct motions while motions in the opposite direction are referred to as retrograde.
Retrograde motion is the apparent backward motion of a planet caused by its being lapped by another planet or vice versa. Both planet move in a direct eastward motion around the sun, but the planet with the inside (smaller) orbit moves faster than the planet on the outside (larger orbit), and when it passes the slower moving planet, each sees the other one as apparently moving backward relative to its motion around the sky.
