I believe the correct answer would be "A" energy source.
Tide is the alternating pattern of rising and falling sea level with respect to land.
There are three types of tide relative to the position of the moon and sun to that of the earth.
1. Spring tides. Occur when the moon sun and earth arrange themselves more or less in a straight line, like an arrow. These tides are the highest and lowest tides.
2. Perigean spring tides. Occur when the new moon or full moon closely aligns with perigee, the closest point to the earth in the moon's orbit. These tides are not as high or low as the spring tides.
3. Neap tides. Occur when the sun and the moon are at right angles as seen from earth.The tides are at minimum range.
The net force on the rocket is 846400 N.
Answer:
Explanation:
It is known that weight is the influence of gravitational force acting on any mass of the object. So in the present case, the weighing force given is equal to the gravitational force acting on the rocket. Thus, the gravitational force will be acting towards downward direction. But an upward force is required by the rocket for thrusting purpose and that force is given as upward force. So the net force acting on the rocket is the vector addition of all the forces acting on the rocket. As in this case, only upward and downward force is acting on the rocket. The vector addition will be equal to subtraction of downward acting gravitational force from upward force or force provided by engine.
Net force = Engine force - Gravitational force = 890000-43600=846400 N
So the net force acting on the rocket is 846400 N.
A. Reduced greenhouse gas emissions.
The phases of the moon are the changing appearances of the moon, as seen from Earth. Which phase happens immediately after a third quarter moon are the following
Explanation:
- After the full moon (maximum illumination), the light continually decreases. So the waning gibbous phase occurs next. Following the third quarter is the waning crescent, which wanes until the light is completely gone -- a new moon.
waning gibbous phase
- The waning gibbous phase occurs between the full moon and third quarter phases. The last quarter moon (or a half moon) is when half of the lit portion of the Moon is visible after the waning gibbous phase.
Time takes by the moon to go through all the phases
about 29.5 days
- It takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant “fixed” stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).
- At 3rd quarter, the moon rises at midnight and sets at noon. Then we see only a crescent. At new, the moon rises at sunrise and sets at sunset, and we don't see any of the illuminated side!
