What else can I help you with?
Is it true or false the second postulate of special relativity says that the speed of light in empty space depends on the motion of the source or of the observer?
False. The speed of light in empty space is a constant, independent of the motion of the source/observer. An observer travelling towards or away from a light source at 99% the speed of light would measure light going the same speed as an observer stationary relative to the light source.
Each time the moon revolves behind the Earth it will pass through the Earth's shadow. True False?
False. Usually the Moon passes north or south of Earth's shadow.
Why The earth builds new crust at divergent boundaries true or false?
false
Is the moon the star closest to earth true or false?
false the moon is not a star
True or false Elements abundant in the body are not abundant on Earth?
False. Elements abundant in the body, such as oxygen, carbon, hydrogen, nitrogen, and calcium, are also abundant on Earth. These elements are essential for life and can be found in various forms in the Earth's rocks, atmosphere, and oceans.
Is this statement true or false the horizon is the point where to an observer the earth and sky appear to meet?
True. The horizon is the line where the Earth's surface and the sky seem to meet from the perspective of an observer. It is influenced by the observer's height and the curvature of the Earth.
Altitude is defined as the distance in degrees of a star below the horizon?
Actually, altitude is the height of an object above a specific reference point, usually the observer's horizon. It is measured in degrees, with 0 degrees being right on the horizon and 90 degrees directly overhead.
What is the correct term Zenith is the angle between an object and the horizon?
If I understand the question, then it includes a false statement.The angle between an object and the horizon is the object's 'elevation' angle.'Zenith' is a point in the sky . . . the point directly over your head, whoseelevation angle is 90 degrees regardless of which direction you're facing..
How do you use a false horizon with a sextant?
To use a false horizon with a sextant, you would need to create an artificial horizon with a still reflecting surface, such as oil in a pan or a small pool of water. You would then line up the celestial body you are measuring with its reflection on the artificial horizon, allowing you to take an accurate sextant reading. This method is useful when the true horizon is obscured or not visible.
When a signal is absent but an observer believes that they perceive the signal anyway?
false alarm
Altitude is defined as the distance in degrees of a star below the horizon.?
false
What are two types of reporting isolating events are observer-reported and media reporting.?
FALSE
Is it true or false that the Earth does not appear to be gaining or losing heat as a planet in space?
False. The Earth is gaining more heat than it is losing, leading to global warming. This increase in heat is primarily due to human activities that release greenhouse gases into the atmosphere, trapping heat and causing temperatures to rise.
Is it true or false the second postulate of special relativity says that the speed of light in empty space depends on the motion of the source or of the observer?
False. The speed of light in empty space is a constant, independent of the motion of the source/observer. An observer travelling towards or away from a light source at 99% the speed of light would measure light going the same speed as an observer stationary relative to the light source.
What is a false link?
a false link is a link that is fake. most will not appear on the screen
Brightness determines how lighter colors appear on the display true or false?
false
Does committed fixed costs have a short term planning horizon-usually one year?
False
