False the light year is not a unit of time it is a unit of distance true.
true
Defining true zenith distance is knowing the difference between Africa and south America.True zenith distance is associated with Greenwich line and meridional zenith distance is defined with the celestial equator which instructs the basin of south america. -AG
False. While our eyes can perceive sunlight in the visible spectrum, the Sun emits energy in a wide range of wavelengths, including ultraviolet and infrared light, which are not visible to the human eye.
It is false. The Earth's orbit is an ellipse (oval), although the distance only varies by about 3.4% from closest to farthest (147 million to 152 million kilometers).
True. The Sun is much closer to Earth than the Moon. The average distance from the Earth to the Sun is about 93 million miles (150 million kilometers), whereas the average distance from the Earth to the Moon is about 238,855 miles (384,400 kilometers).
False the light year is not a unit of time it is a unit of distance true.
True. Work is measured in joules, where 1 joule is equal to the work done when a force of 1 newton is applied over a distance of 1 meter in the direction of the force.
false
False. The wavelength of a wave is measured from crest to crest or trough to trough, representing the distance between two corresponding points on a wave cycle.
That is correct.That is correct.That is correct.That is correct.

False. The speed of light is always the same: 300,000 kilometers per second.
true
It is false.
False. The wavelength of a wave is actually measured from crest to crest, or trough to trough, not from crest to trough.
True. Work is measured in joules, which is the unit of energy in the International System of Units (SI).
